小編給大家分享一下基于.NET Core 3.1網(wǎng)站是如何開發(fā)和部署的，希望大家閱讀完這篇文章后大所收獲，下面讓我們一起去探討吧！
這里選擇vscode + .net core cli 是因?yàn)椴还茉赪indows還是Linux和Mac上都能使用這一套工具，而且命令行工具也非常強(qiáng)大。
在vscode插件市場中搜索安裝即可
新手還可以去這里了解vscode的強(qiáng)大之處
這里使用Centos7，因?yàn)?NET Core 3.1只支持7及以上版本
配置網(wǎng)絡(luò)
nmcli conn nmcli conn add ifname ens34 con-name ens34 type enthernet autoconnect yes ip4 192.168.30.110/24
安裝mariadb-server
使用XShell連接服務(wù)器
cd /etc/yum.repos.d/ mkdir bak mv Cen* ./bak/ curl -o /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-7.repo yum install mariadb-server.x86_64
啟動(dòng)服務(wù)
systemctl enable mariadb.service systemctl start mariadb.service systemctl status mariadb
執(zhí)行安全加強(qiáng)腳本
mysql_secure_installation
創(chuàng)建數(shù)據(jù)庫并授權(quán)訪問帳號

① 使用EF Core 生成模型
DB First模式
全局安裝ef工具
dotnet tool install --global dotnet-ef
測試工具是否安裝成功
D:\dotnet_core\HotelWebMVC>dotnet ef
_/\__
---==/ \\
___ ___ |. \|\
| __|| __| | ) \\\
| _| | _| \_/ | //|\\
|___||_| / \\\/\\
Entity Framework Core .NET Command-line Tools 3.1.0
Usage: dotnet ef [options] [command]
Options:
--version Show version information
-h|--help Show help information

Use "dotnet ef [command] --help" for more information about a command.只要看到有這個(gè)獨(dú)角獸就代表安裝成功了。
添加需要的NuGet包
dotnet add package Microsoft.EntityFrameworkCore.Design dotnet add package Pomelo.EntityFrameworkCore.MySql
使用EF工具
查看幫助
D:\dotnet_core\HotelWebMVC\DAL>dotnet ef dbcontext scaffold --help Usage: dotnet ef dbcontext scaffold [arguments] [options] Arguments: <CONNECTION> The connection string to the database. <PROVIDER> The provider to use.

連接數(shù)據(jù)庫生成模型數(shù)據(jù)
D:\dotnet_core\HotelWebMVC\DAL>dotnet ef dbcontext scaffold "Server=192.168.30.110,3306;DataBase=HotelWebDb;User=sa;Pwd=110;" "Pomelo.EntityFrameworkCore.MySql" -s ..\HotelWebMVC\HotelWebMVC.csproj Build started... Build succeeded.
修改連接字符串的位置
修改在appsettings.json文件中添加連接字符串
{
"Logging": {
"LogLevel": {
"Default": "Information",
"Microsoft": "Warning",
"Microsoft.Hosting.Lifetime": "Information"
}
},
"AllowedHosts": "*",
"ConnectionStrings":{
"HotelWeb":"Server=192.168.30.110,3306;DataBase=HotelWebDb;User=sa;Pwd=110;"
}
}然后在Sartup.cs文件獲取連接字符串
public void ConfigureServices(IServiceCollection services)
{
services.AddControllersWithViews();
string connString=Configuration.GetConnectionString("HotelWeb");
services.AddDbContext<DAL.HotelWebDbContext>(options=>options.UseMySql(connString, x => x.ServerVersion("5.5.64-mariadb")));
}最后DbContenxt類中配置就可以刪除了
移動(dòng)DAL生成的實(shí)體類到Models模塊
修改實(shí)體類中的命名空間
② 另一種使用ADO.NET實(shí)現(xiàn)
不是這次的重點(diǎn)，所以略過。
1.編寫一個(gè)簡單的Helper類
using Microsoft.EntityFrameworkCore;
namespace DAL
{
class EFCoreHelper
{
private DbContext dbContext = null;
public EFCoreHelper(DbContext context)
{
this.dbContext = context;
}
/// <summary>
/// 添加實(shí)體
/// </summary>
/// <typeparam name="T"></typeparam>
public int Add<T>(T entity) where T : class
{
dbContext.Entry(entity).State=EntityState.Added;
return dbContext.SaveChanges();
}
/// <summary>
/// 修改實(shí)體的全部屬性
/// </summary>
/// <typeparam name="T"></typeparam>
public int Modify<T>(T entity) where T:class
{
dbContext.Entry(entity).State=EntityState.Modified;
return dbContext.SaveChanges();
}
/// <summary>
/// 刪除實(shí)體
/// </summary>
/// <typeparam name="T"></typeparam>
public int Delete<T>(T entity) where T:class
{
dbContext.Entry(entity).State=EntityState.Deleted;
return dbContext.SaveChanges();
}
}
}2.完成新聞后臺數(shù)據(jù)訪問類
數(shù)據(jù)訪問類
using System;
using System.Linq;
using System.Collections.Generic;
using Models;
namespace DAL
{
public class NewsService
{
private EFCoreHelper helper = new EFCoreHelper(new HotelWebDbContext());
/// <summary>
/// 添加新聞
/// </summary>
/// <param name="news"></param>
/// <returns></returns>
public int AddNews(News news) => helper.Add(news);
/// <summary>
/// 修改新聞
/// </summary>
/// <param name="news"></param>
/// <returns></returns>
public int ModifyNews(News news) => helper.Modify(news);
/// <summary>
/// 刪除新聞
/// </summary>
/// <param name="newssId"></param>
/// <returns></returns>
public int DeleteNews(string newssId)
{
News news = new News() { Id = Convert.ToUInt32(newssId) };
return helper.Delete(news);
}
/// <summary>
/// 獲取指定數(shù)量的新聞列表
/// </summary>
/// <param name="count"></param>
/// <returns></returns>
public List<News> GetNews(int count)
{
using (HotelWebDbContext dbContext = new HotelWebDbContext())
{
return (from n in dbContext.News orderby n.PublishTime descending select n).Take(count).ToList();
}
}
/// <summary>
/// 根據(jù)ID獲取新聞信息
/// </summary>
/// <param name="newssId"></param>
/// <returns></returns>
public News GetNewsById(string newssId)
{
uint id = Convert.ToUInt32(newssId);
using (HotelWebDbContext dbContext = new HotelWebDbContext())
{
return (from n in dbContext.News where n.Id == id select n).FirstOrDefault();
}
}
/// <summary>
/// 獲取所有的新聞分類
/// </summary>
/// <returns></returns>
public List<NewsCategory> GetCategories()
{
using (HotelWebDbContext dbContext = new HotelWebDbContext())
{
return (from c in dbContext.NewsCategory select c).ToList();
}
}
}
}業(yè)務(wù)邏輯部分
using System.Collections.Generic;
using DAL;
using Models;
namespace BLL
{
public class NewsManager
{
private NewsService objService=new NewsService();
/// <summary>
/// 添加新聞
/// </summary>
/// <param name="news"></param>
/// <returns></returns>
public int AddNews(News news) => objService.AddNews(news);
/// <summary>
/// 修改新聞
/// </summary>
/// <param name="news"></param>
/// <returns></returns>
public int ModifyNews(News news) => objService.ModifyNews(news);
/// <summary>
/// 刪除新聞
/// </summary>
/// <param name="newssId"></param>
/// <returns></returns>
public int DeleteNews(string newssId) => objService.DeleteNews(newssId);
/// <summary>
/// 獲取指定數(shù)量的新聞列表
/// </summary>
/// <param name="count"></param>
/// <returns></returns>
public List<News> GetNews(int count) => objService.GetNews(count);
/// <summary>
/// 根據(jù)ID獲取新聞信息
/// </summary>
/// <param name="newssId"></param>
/// <returns></returns>
public News GetNewsById(string newssId) => objService.GetNewsById(newssId);
/// <summary>
/// 獲取所有的新聞分類
/// </summary>
/// <returns></returns>
public List<NewsCategory> GetCategories() => objService.GetCategories();
}
}3.添加一個(gè)控制臺項(xiàng)目用來測試
添加需要的引用
dotnet add package Microsoft.EntityFrameworkCore.Design dotnet add package Pomelo.EntityFrameworkCore.MySql
DbContext中的數(shù)據(jù)庫連接字符串添加回去
protected override void OnConfiguring(DbContextOptionsBuilder optionsBuilder)
{
if(!optionsBuilder.IsConfigured)
{
optionsBuilder.UseMySql("Server=192.168.30.110;DataBase=HotelWebDb;User=sa;Pwd=110;",x => x.ServerVersion("5.5.64-mariadb"));
}
}編寫測試代碼
News news=new News()
{
NewsContent="你好這是一個(gè)測試新聞內(nèi)容",
NewsTitle="測試新聞",
CategoryId=1
};
Console.WriteLine(objNews.AddNews(news));啟動(dòng)調(diào)試
選擇啟動(dòng)項(xiàng)目有兩種方法
①通過solution explorer 插件選擇
②通過配置launch.json 文件啟動(dòng)
然后修改啟動(dòng)程序入口就可以了
{
"name": ".NET Core Launch (console)",
"type": "coreclr",
"request": "launch",
"preLaunchTask": "build",
"program": "${workspaceFolder}/UnitTestPro/bin/Debug/netcoreapp3.1/UnitTestPro.dll",
"args": [],
"cwd": "${workspaceFolder}",
"stopAtEntry": false,
"console": "internalConsole"
},還要修改task文件，否則測試項(xiàng)目中新加的代碼不能被執(zhí)行。
結(jié)果查驗(yàn)
結(jié)果符合預(yù)期
注意事項(xiàng)
修改新聞?wù){(diào)用的方法不支持部分屬性修改，如果對象屬性不設(shè)置，那么沒有設(shè)置的字段被設(shè)置為空。
后面有字段部分修改的方法。
News news=new News()
{
Id=1008,
NewsContent="修改新聞的內(nèi)容",
NewsTitle="這是被修改的新聞標(biāo)題",
};
Console.WriteLine(objNews.ModifyNews(news));
4.編寫菜品預(yù)訂
5.編寫招聘
6.編寫投訴和建議
7.管理員登錄
類似不再貼代碼
1.完成前端Html代碼的編寫
不多說
2.完成MVC項(xiàng)目中控制器和視圖的文件添加
這個(gè)只能手動(dòng)添加，不像VS有模板可用
3.復(fù)制網(wǎng)站的靜態(tài)資源
asp.net core 網(wǎng)站靜態(tài)資源都是放在wwwroot目錄的，并且文件名一般是小寫。
4.在視圖中引用資源
MVC框架可以直接識別在wwwroot中的靜態(tài)資源，不用寫顯示的寫出目錄名。
<link rel="stylesheet" href="~/lib/bootstrap/dist/css/bootstrap.min.css" rel="external nofollow" rel="external nofollow" /> <link rel="stylesheet" href="~/css/site.css" rel="external nofollow" rel="external nofollow" />
5.編寫動(dòng)作方法
public IActionResult Index()
{
return View();
}6.添加視圖
7.啟動(dòng)調(diào)試
首頁效果圖
8.視圖與控制器之間傳遞數(shù)據(jù)
使用ViewData
視圖的網(wǎng)頁標(biāo)題可以使用這種方式傳遞
public IActionResult Index()
{
ViewData["title"]="好運(yùn)來酒店";
ViewBag.list=new NewsManager().GetNews(4);
return View();
}視圖中引用數(shù)據(jù)
<!doctype html> <html lang="zh"> <head> <!-- Required meta tags --> <meta charset="utf-8"> <meta name="viewport" content="width=device-width, initial-scale=1, shrink-to-fit=no"> <!-- Bootstrap CSS --> <link rel="stylesheet" href="~/lib/bootstrap/dist/css/bootstrap.min.css" rel="external nofollow" rel="external nofollow" /> <link rel="stylesheet" href="~/css/site.css" rel="external nofollow" rel="external nofollow" /> <title>@ViewData["title"]-舒適快捷經(jīng)濟(jì)</title> </head>
使用ViewBag
這是所謂的動(dòng)態(tài)類型，直接無中生有造一個(gè)屬性
ViewBag.list=new NewsManager().GetNews(4);
視圖中引用
@foreach (News item in @ViewBag.list) {
<div class="d-flex flex-row justify-content-between newslist">
<div class="p-2">
<a href="/News/NewsDetail?id=@item.Id" rel="external nofollow" rel="external nofollow" >@item.NewsTitle</a>
</div>
<div class="p-2">
@item.PublishTime.ToShortDateString()
</div>
</div>使用viewmodel
控制器中使用View的重載方法傳遞viewmodel
public IActionResult Index()
{
ViewData["title"]="好運(yùn)來酒店";
return View(new NewsManager().GetNews(4));
}視圖中先聲明后使用
Specify a model using the @model directive. Use the model with @Model:
@model list<News>
...
@foreach (News item in @Model) {
<div class="d-flex flex-row justify-content-between newslist">
<div class="p-2">
<a href="/News/NewsDetail?id=@item.Id" rel="external nofollow" rel="external nofollow" >@item.NewsTitle</a>
</div>
<div class="p-2">
@item.PublishTime.ToShortDateString()
</div>
</div>修改后的首頁
9.分部視圖
創(chuàng)建分部視圖
分部視圖的創(chuàng)建和其他視圖的創(chuàng)建沒有任何區(qū)別，只是它作為其他視圖的一部分來視圖用。
避免視圖代碼的重復(fù)。
在其他視圖中使用分部視圖
引用分部視圖使用特殊的標(biāo)簽 <partial name="..." />
@model List<News>
<div class="row">
<div class="col-md-4">
<partial name="../Shared/_LeftContentPartial.cshtml" />
</div>
<div class="col-md-8">
<div class="lefttitle righttitle">您現(xiàn)在所在的位置:中式餐廳酒店>新聞動(dòng)態(tài)</div>
<div class="bg-light">
@foreach (News item in @Model) {
<div class="d-flex flex-row justify-content-between">
<div class="p-2"><a href="NewsDetail?id=@item.Id" rel="external nofollow" >@item.NewsTitle</a></div>
<div class="p-2">@item.PublishTime.ToShortDateString()</div>
</div>
}
</div>
</div>
</div>10.使用Section布局定義
@RenderSection("js",required:false)使用
@section js{
<script type="text/javascript">
function changeFontSize(fontSize) {
//獲取要變化的對象
var divContent = $(".row .m-4");
divContent.css("font-size",fontSize);
}
</script>
}11.表單驗(yàn)證
使用模型驗(yàn)證方式實(shí)現(xiàn)
添加驗(yàn)證特性
public partial class DishBook
{
public uint Id { get; set; }
public string HotelName { get; set; }
[Required(ErrorMessage = "{0}不能為空")]
[Display(Name = "消費(fèi)時(shí)間")]
public DateTime? ConsumeTime { get; set; }
[Required(ErrorMessage = "{0}不能為空")]
[RegularExpression(@"^\d+$", ErrorMessage = "請輸入正確的{0}")]
[Display(Name = "消費(fèi)人數(shù)")]
public uint? ConsumePersons { get; set; }
public string RoomType { get; set; }
[Required(ErrorMessage = "{0}不能為空")]
[RegularExpression(@"^(13[0-9]|14[5|7]|15[0|1|2|3|5|6|7|8|9]|18[0|1|2|3|5|6|7|8|9])\d{8}$", ErrorMessage = "請輸入正確的{0}")]
[Display(Name = "手機(jī)號碼")]
public string CustomerPhone { get; set; }
[Required(ErrorMessage = "{0}不能為空")]
[Display(Name = "姓名")]
public string CustomerName { get; set; }
[EmailAddress(ErrorMessage = "請輸入正確的{0}")]
[Display(Name = "電子郵件")]
public string CustomerEmail { get; set; }
public string Comments { get; set; }
public DateTime BookTime { get; set; }
public int? BookStatus { get; set; }
// 擴(kuò)展屬性
[Required(ErrorMessage = "{0}不能為空")]
[Remote(action:"CheckVcode",controller:"Dish")]
[Display(Name = "驗(yàn)證碼")]
public string ValidationCode { get; set; }
}使用 Tag Helper 完成前端代碼編寫

</div>引入jQuery驗(yàn)證插件
這個(gè)是插件MVC項(xiàng)目時(shí)，模板自動(dòng)生成的
@section js{
<partial name="../Shared/_ValidationScriptsPartial.cshtml" />
<script src="~/lib/My97DatePicker/WdatePicker.js"></script>
}
Tag Helper自動(dòng)根據(jù)數(shù)據(jù)類型生成對應(yīng)的輸入框類型
可以手動(dòng)設(shè)置 type 來覆蓋
驗(yàn)證碼提交到服務(wù)器驗(yàn)證
使用 [Remote] 特性
詳細(xì)文檔參考：https://docs.microsoft.com/en-us/aspnet/core/mvc/models/validation?view=aspnetcore-3.1
The jQuery Validate remote method expects a JSON response:
注意：The [Remote] attribute is in the Microsoft.AspNetCore.Mvc namespace.
1.創(chuàng)建區(qū)域項(xiàng)目
建立區(qū)域項(xiàng)目目錄結(jié)構(gòu)
- Project name
Areas
Admin //分區(qū)項(xiàng)目1
Controllers
Views
Services //分區(qū)項(xiàng)目2
Controllers
Views添加路由規(guī)則
在Startup.cs文件中添加區(qū)域項(xiàng)目路由規(guī)則
app.UseEndpoints(endpoints =>
{
endpoints.MapControllerRoute(
name: "Admin",
pattern: "{area:exists}/{controller=Home}/{action=Index}/{id?}"
);
endpoints.MapControllerRoute(
name: "default",
pattern: "{controller=Home}/{action=Index}/{id?}"
);
});測試頁面
如果有和主項(xiàng)目同名的控制器使用區(qū)域特性區(qū)分
using Microsoft.AspNetCore.Mvc;
namespace HotelWebMVC.Areas.Admin.Controllers
{
[Area("Admin")]
public class HomeController : Controller
{
public IActionResult Index()
{
return View();
}
public IActionResult Welcome()
{
ViewData["Message"] = "Your welcome message";
return View();
}
}
}
如果不打區(qū)域標(biāo)記區(qū)分，啟動(dòng)項(xiàng)目會(huì)包錯(cuò)。
2.使用Cookie保存登錄憑證
添加依賴包
dotnet add package Microsoft.AspNetCore.Authentication.Cookies
配置服務(wù)
public void ConfigureServices(IServiceCollection services)
{
services.AddControllersWithViews();
services.AddDistributedMemoryCache();
services.AddSession(options =>
{
// Set a short timeout for easy testing.
options.IdleTimeout = TimeSpan.FromSeconds(300);
options.Cookie.HttpOnly = true;
// Make the session cookie essential
options.Cookie.IsEssential = true;
});
services.AddAuthentication(CookieAuthenticationDefaults.AuthenticationScheme)
.AddCookie(options=>{
options.Cookie.HttpOnly=true;
options.ExpireTimeSpan=TimeSpan.FromMinutes(5);
options.LoginPath="/admin";
// options.AccessDeniedPath="/403.html";
}
);
string connString = Configuration.GetConnectionString("HotelWeb");
services.AddDbContext<DAL.HotelWebDbContext>(options => options.UseMySql(connString, x => x.ServerVersion("5.5.64-mariadb")));
}啟用認(rèn)證服務(wù)添加的位置有要求：必須在app.UseRouting 和 app.UseEndpoints 之間。
app.UseRouting();
app.UseSession();
app.UseAuthentication();
app.UseAuthorization();
app.UseEndpoints(endpoints =>
{
endpoints.MapControllerRoute(
name: "admin",
pattern: "{area:exists}/{controller=SysAdmin}/{action=Index}/{id?}"
);
endpoints.MapControllerRoute(
name: "default",
pattern: "{controller=Home}/{action=Index}/{id?}");
});登錄成功后簽發(fā)憑證
using System.Security.Claims; using Microsoft.AspNetCore.Mvc; using Microsoft.AspNetCore.Authentication; using Microsoft.AspNetCore.Authentication.Cookies;
List<Claim> claims = new List<Claim>() { new Claim("username", admin.LoginName) };
ClaimsIdentity claimsIdentity = new ClaimsIdentity(claims, CookieAuthenticationDefaults.AuthenticationScheme);
AuthenticationProperties properties = new AuthenticationProperties()
{
IsPersistent = true
};
await HttpContext.SignInAsync
(
CookieAuthenticationDefaults.AuthenticationScheme,
new ClaimsPrincipal(claimsIdentity),
properties
);其他需登錄后才能訪問的資源，在控制器上添加 [Authorize]標(biāo)記
[Authorize]
public class HomeController : Controller
{
public IActionResult Index()
{
return View();
}
public IActionResult Welcome()
{
ViewData["Message"] = "Your welcome message";
return View();
}
}3.使用ajax提交表單
在dotnet core 中不再支持@Ajax.Form方式，而是使用jquery插件的方式支持了。
通過定義data-* 屬性來支持類似的功能
和Ajax助手的對照
====================================================== AjaxOptions HTML attribute ====================================================== Confirm data-ajax-confirm HttpMethod data-ajax-method InsertionMode data-ajax-mode LoadingElementDuration data-ajax-loading-duration LoadingElementId data-ajax-loading OnBegin data-ajax-begin OnComplete data-ajax-complete OnFailure data-ajax-failure OnSuccess data-ajax-success UpdateTargetId data-ajax-update Url data-ajax-url ======================================================
這個(gè)特性只能在form和a標(biāo)簽上起作用
使用方法：
①下載插件并引用到項(xiàng)目中
地址：https://github.com/aspnet/jquery-ajax-unobtrusive/releases
將src文件夾中的js文件拷貝到項(xiàng)目對應(yīng)的存放位置
②編寫需要的js函數(shù)
編寫回調(diào)函數(shù)
<script>
var onSuccess=function(data){
alert(data);
$("#mainForm")[0].reset();
dishImg.src = "/images/default.png";
};
var onFailed=function(data){
alert(data);
};
</script>③使用data屬性改寫標(biāo)簽
這里注意：要使用ajax提交表單，data-ajax="true"必須要設(shè)置為true。
data-ajax-confirm=“確認(rèn)要提交嗎？” 這里是彈出框的內(nèi)容，不是具體的函數(shù)名
data-ajax-begin
data-ajax-complete
data-ajax-failure
data-ajax-success
這些屬性值就是回調(diào)函數(shù)的名稱。
4.CKeditor使用
推薦使用ckeditor4，因?yàn)?版本中文輸入有問題。
使用步驟：
下載編輯器的軟件包
在頁面中引入它的js腳本
<script src="../../third_files/ckeditor4/ckeditor.js"></script>
使用texterea作為目標(biāo)
編輯器的高度可以config.js文件中設(shè)置
<textarea id="editor" name="editor" rows="20"></textarea>
在js中創(chuàng)建
<script> CKEDITOR.replace( 'editor' ); </script>
自定義配置
修改配置文件config.js，推薦直接在默認(rèn)的文件中添加需要的配置。
CKEDITOR.editorConfig = function( config ) {
config.language = 'es';
config.uiColor = '#F7B42C';
config.height = 300;
config.toolbarCanCollapse = true;
};獲取編輯器的內(nèi)容
用于提交前驗(yàn)證是否有內(nèi)容,NewsContent是編輯器textarea的id
var content=CKEDITOR.instances.NewsContent.getData();
注意此時(shí)數(shù)據(jù)驗(yàn)證通過，使用js提交表單的話，編輯器并沒有替換原來的內(nèi)容，需要手動(dòng)替換$("#NewsContent").html(content);
不然提交到控制器中是沒有值的。
var onSubmit=function(){
var content=CKEDITOR.instances.NewsContent.getData();
if(content==""){
alert("新聞內(nèi)容不能為空");
}
else{
$("#NewsContent").html(content);
$("#mainForm").submit();
}
}清空編輯器的內(nèi)容
CKEDITOR.instances.NewsContent.setData("");
In rare cases it may happen that the server or application configuration
will reject submitted HTML content if it is not encoded first (e.g. ASP.NET ValidateRequest).
In such case check the config.htmlEncodeOutput option.
config.htmlEncodeOutput = true;
上傳圖片設(shè)置
需要外部插件：file browser,popup,filetools
配置config.js文件
config.filebrowserBrowseUrl = ‘/browser/browse.php'; config.filebrowserUploadUrl = ‘/uploader/upload.php';
控制器中的參數(shù)使用 (IFormFile upload) 使用的是upload的參數(shù)名。
如何給一個(gè)響應(yīng)，放棄不用這個(gè)，使用filebrowserBrowseUrl這個(gè)功能，里面也有上傳
具體方法是：
響應(yīng)的js代碼如下：
<script>
// Helper function to get parameters from the query string.
function getUrlParam( paramName ) {
var reParam = new RegExp( '(?:[\?&]|&)' + paramName + '=([^&]+)', 'i' );
var match = window.location.search.match( reParam );
return ( match && match.length > 1 ) ? match[1] : null;
}
var upload=function(){
var file=$(".btnUpload>input")[0].files[0];
if(file==null){
alert("請選擇上傳圖片");
}
else{
var formData=new FormData();
formData.append("upload",file);
// 實(shí)例化一個(gè)AJAX對象
var xhr = new XMLHttpRequest();
xhr.onload = function() {
$(".border3").first().before('<div class="w-25 p-3 border3"><span class="d-inline-block"><h4><span class="badge badge-info rotated">new</span></h4><img class="img-thumbnail" src="/images/news/'+xhr.responseText+'" onclick="select(this)"></span><div class="text-center p-2">'+xhr.responseText+'</div></div>');
}
xhr.open("post",'@Url.Action("UploadImage","News")',true);
// 發(fā)送表單數(shù)據(jù)
xhr.send(formData);
}
}
var selectedImg=null;
var select=function(img){
if(selectedImg!=null){
selectedImg.parents(".border3").removeClass("selected");
}
selectedImg=$(img);
selectedImg.parents(".border3").addClass("selected");
}
var choose=function(){
if(selectedImg!=null){
var funcNum = getUrlParam( 'CKEditorFuncNum' );
var fileUrl = selectedImg.attr("src");
window.opener.CKEDITOR.tools.callFunction( funcNum, fileUrl );
window.close();
}
else{
alert("請選裝圖片");
}
}
</script>
5.其他功能省略代碼
1.抽取接口
通過vs來抽取接口，效率高。
2.重新組織項(xiàng)目結(jié)構(gòu)
新增IDAL、IBLL、DBUtility
UI–>IBLL–>IDAL–>Models
BLL–>IBLL、IDAL
IDAL–>Models
DAL–>IDAL、DBUtility
3.注冊依賴服務(wù)
public void ConfigureServices(IServiceCollection services)
{
//其他代碼省略了
...
services.AddDbContext<DBUtility.HotelWebDbContext>(
options => options.UseMySql(
Configuration.GetConnectionString("HotelWeb"),
x => x.ServerVersion("5.5.64-mariadb")
)
);
services.AddTransient<INewsManager, NewsManager>();
services.AddTransient<IDishManager, DishManager>();
services.AddTransient<IDishBookManager, DishBookManager>();
services.AddTransient<ISuggestionManager, SuggestionManager>();
services.AddTransient<IRecruitmentManager, RecruitmentManager>();
services.AddTransient<ISysAdminManager, SysAdminManager>();
services.AddTransient<INewsService,NewsService>();
services.AddTransient<IDishService,DishService>();
services.AddTransient<IDishBookService,DishBookService>();
services.AddTransient<ISuggestionService,SuggestionService>();
services.AddTransient<IRecruitmentService,RecruitmentService>();
services.AddTransient<ISysAdminService,SysAdminService>();
}4.修改代碼使用依賴注入
public class HomeController : Controller
{
private readonly INewsManager newsManager;
private readonly ISuggestionManager suggestionManager;
private readonly IRecruitmentManager recruitmentManager;
public HomeController(
INewsManager newsManager,
ISuggestionManager suggestionManager,
IRecruitmentManager recruitmentManager)
{
this.newsManager = newsManager;
this.suggestionManager = suggestionManager;
this.recruitmentManager = recruitmentManager;
}
// ...
}5.測試
啟動(dòng)項(xiàng)目也沒有什么問題
1.項(xiàng)目配置
dotnet core 中沒有Web.conf文件了。
查看文檔，都是通過Startup.cs中配置項(xiàng)目的。
暫時(shí)放棄配置。
2.命令行發(fā)布項(xiàng)目
CLI 提供了發(fā)布項(xiàng)目的相關(guān)命令
dotnet publish -c Release --no-self-contained -o /path/to/save/project/
3.另一種方式使用vs發(fā)布
很簡單，下一步下一步做就好了。
1.在Centos7 上安裝運(yùn)行時(shí)
Register Microsoft key and feed
sudo rpm -Uvh https://packages.microsoft.com/config/centos/7/packages-microsoft-prod.rpm
Install the ASP.NET Core runtime
sudo yum install dotnet-sdk-3.1
2.安裝libgdiplus
因?yàn)轫?xiàng)目中使用驗(yàn)證碼，需要用到這個(gè)命名空間：System.Drawing.Common
速度太慢，放棄。
3.將項(xiàng)目目錄上傳到linux
使用xshell 的ftp 輕松完成。
4.測試項(xiàng)目是否運(yùn)行
cd /var/www/HotelWeb/ dotnet HotelWeb.dll [root@centos7 HotelWeb]# dotnet HotelWebMVC.dll info: Microsoft.Hosting.Lifetime[0] Now listening on: http://localhost:5000 info: Microsoft.Hosting.Lifetime[0] Application started. Press Ctrl+C to shut down. info: Microsoft.Hosting.Lifetime[0] Hosting environment: Production info: Microsoft.Hosting.Lifetime[0] Content root path: /var/www/HotelWeb
5.安裝Nginx并配置
yum install nginx
vim /etc/nginx/nginx.conf
---------------
# 刪除nginx默認(rèn)的server，添加下面兩個(gè)
server {
listen 80 default_server;
return 444;
}
server {
listen 80;
server_name *.hotel.com;
location / {
proxy_pass http://localhost:5000;
proxy_http_version 1.1;
proxy_set_header Upgrade $http_upgrade;
proxy_set_header Connection keep-alive;
proxy_set_header Host $host;
proxy_cache_bypass $http_upgrade;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_set_header X-Forwarded-Proto $scheme;
}
}
----------------6.啟動(dòng)nginx
systemctl start nginx nginx -t # 配置確認(rèn)沒有問題后，重新載入配置 nginx -s reload
7.瀏覽器測試
修改win7的host
www.hotel.com 192.168.30.110
8.最后的問題
因?yàn)閘ibgdiplus這個(gè)庫沒有安裝，所以進(jìn)入驗(yàn)證碼的頁面會(huì)有報(bào)錯(cuò)。
fail: Microsoft.AspNetCore.Diagnostics.ExceptionHandlerMiddleware[1]
An unhandled exception has occurred while executing the request.
System.TypeInitializationException: The type initializer for 'Gdip' threw an exception.
---> System.DllNotFoundException: Unable to load shared library 'libgdiplus' or one of its dependencies.
9.修改dotnet監(jiān)聽端口
在Program.cs 文件中修改
public static IHostBuilder CreateHostBuilder(string[] args) =>
Host.CreateDefaultBuilder(args)
.ConfigureWebHostDefaults(webBuilder =>
{
webBuilder.ConfigureKestrel(serverOptions =>
{
serverOptions.Listen(IPAddress.Any, 5000);
})
.UseStartup<Startup>();
});
}修改后
[root@centos7 HotelWeb]# dotnet HotelWebMVC.dll info: Microsoft.Hosting.Lifetime[0] Now listening on: http://0.0.0.0:5000 info: Microsoft.Hosting.Lifetime[0] Application started. Press Ctrl+C to shut down. info: Microsoft.Hosting.Lifetime[0] Hosting environment: Production info: Microsoft.Hosting.Lifetime[0] Content root path: /var/www/HotelWeb [root@centos7 ~]# ss -tna State Recv-Q Send-Q Local Address:Port Peer Address:Port LISTEN 0 128 *:5000 *:* LISTEN 0 50 *:3306 *:* LISTEN 0 128 *:111 *:* LISTEN 0 128 *:80 *:* LISTEN 0 128 *:22 *:* LISTEN 0 100 127.0.0.1:25 *:* ESTAB 0 0 192.168.30.110:22 192.168.30.88:1581 ESTAB 0 52 192.168.30.110:22 192.168.30.88:1516 LISTEN 0 128 :::111 :::* LISTEN 0 128 :::22 :::* LISTEN 0 100 ::1:25 :::*
