小編給大家分享一下.NET Core如何實(shí)現(xiàn)單文件發(fā)布靜態(tài)編譯AOT CoreRT,希望大家閱讀完這篇文章之后都有所收獲,下面讓我們一起去探討吧!
首先確保安裝C++編譯環(huán)境,以及.NET Core 2.0 以上版本SDK。
新建WebAPI應(yīng)用
打開(kāi)命令提示符,輸入如下:
dotnet new webapi -o zeroapi cd zeroapi
新建WebAPI應(yīng)用。
添加CoreRT到項(xiàng)目
目前CoreRT還是alpha版,在myget上有包。
首先添加一個(gè)nuget.config
dotnet new nuget
然后在 <packageSources>
節(jié)點(diǎn)添加如下:
<add key="dotnet-core" value="https://dotnet.myget.org/F/dotnet-core/api/v3/index.json" /> <add key="nuget.org" value="https://api.nuget.org/v3/index.json" protocolVersion="3" />
接著添加Microsoft.DotNet.ILCompiler包引用:
dotnet add package Microsoft.DotNet.ILCompiler -v 1.0.0-alpha-*
替換默認(rèn)services并處理反射
打開(kāi)Startup.cs ,將 services.AddMvc();
替換成 services.AddMvcCore().AddJsonFormatters();
接著創(chuàng)建一個(gè)rd.xml 配置文件,用于反射處理運(yùn)行時(shí),確保反射程序集編譯到程序中。
rd.xml配置文件如下:
<Directives> <Application> <Assembly Name="zeroapi" Dynamic="Required All" /> <Assembly Name="Microsoft.AspNetCore.Server.Kestrel.Core"> <Type

Name="System.Linq.Expressions.ExpressionCreator`1[[System.Func`2[[System.Object,System.Private.CoreLib],[System.Object,System.Private.CoreLib]],System.Private.CoreLib]]" Dynamic="Required All" /> </Assembly> <Assembly Name="Microsoft.Extensions.ObjectPool"> <Type Name="Microsoft.Extensions.ObjectPool.DefaultObjectPoolProvider" Dynamic="Required All" /> </Assembly> <Assembly

Name="Microsoft.Extensions.Configuration.Json.JsonConfigurationSource" Dynamic="Required All" /> </Assembly> </Application> </Directives>
其中如果你要替換成自己的程序,更改 <Assembly Name="zeroapi" Dynamic="Required All" />
中的Name。
打開(kāi)zeroapi.csproj
在<PropertyGroup>
節(jié)點(diǎn)下將 <RdXmlFile>rd.xml</RdXmlFile>
加入。
接著將 <PackageReference Include="Microsoft.AspNetCore.All" Version="2.0.3" />
替換成如下:
<PackageReference Include="Microsoft.AspNetCore" Version="2.0.1" /> <PackageReference Include="Microsoft.AspNetCore.Mvc.Core" Version="2.0.1" /> <PackageReference Include="Microsoft.AspNetCore.Mvc.Formatters.Json" Version="2.0.1" />
接著將 ValuesController 更改一下,確保功能正常,如下:
public class ValuesController { [HttpGet("/")] public string Hello() => "Hello World! LineZero AOT"; // GET api/values [HttpGet("/api/values")] public IEnumerable<string> Get() { return new string[] { "AOT", "CoreRT" }; } // GET api/values/5 [HttpGet("/api/values/{id}")] public string Get(int id) { return "Your value is " + id; } }
程序改造完成,接著最重要的發(fā)布。
還原并發(fā)布
發(fā)布之前,使用dotnet run 確保功能正常運(yùn)行。
發(fā)布請(qǐng)打開(kāi) x64 Native Tools Command Prompt for VS 2017 ,注意一定在此命令行發(fā)布。在開(kāi)始菜單找到 Visual Studio 2017,打開(kāi)就能找到。
發(fā)布命令還是 dotnet publish -r <RID> -c <Configuration>
這里發(fā)布Windows 64位 dotnet publish -r win-x64 -c release
,初次的話會(huì)默認(rèn)還原對(duì)應(yīng)的包,需要一些時(shí)間。
發(fā)布完成后,打開(kāi)bin\x64\release\netcoreapp2.0\win-x64\publish 文件夾,里面zeroapi.exe即為最終文件,執(zhí)行即可。
可以看到最終大小為21m左右。然后訪問(wèn)http://localhost:5000/ 如圖:
控制臺(tái)Demo
新建一個(gè)控制臺(tái)應(yīng)用,使用AOT發(fā)布。
單純控制臺(tái),沒(méi)有反射的內(nèi)容,無(wú)需要rd.xml 文件。
代碼如下:
class Program { static void Main(string[] args) { Console.WriteLine("Hello World!"); Console.WriteLine("LineZero AOT Demo!"); Console.ReadKey(); } }
最終 dotnet publish -r win-x64 -c release
發(fā)布
最終單個(gè)文件大小不到4m!
