小程序中如何利用支付寶的SDK獲取用戶User ID

這篇文章主要介紹了小程序中如何利用支付寶的SDK獲取用戶User ID，具有一定借鑒價(jià)值，感興趣的朋友可以參考下，希望大家閱讀完這篇文章之后大有收獲，下面讓小編帶著大家一起了解一下。

支付寶小程序前端

app.js

App({
  globalData:{
    studentid:'',
    username:'',
    apiurl: 'http://XXX'
  }, 
  getUserInfo(){
    var that = this
    return new Promise((resovle,reject)=>{
      if(this.userInfo) resovle(this.userInfo);
      
      //調(diào)用用戶授權(quán) api 獲取用戶信息
      my.getAuthCode({
        scopes: 'auth_user', 
        success:(res) =>{
           if (res.authCode) {    
             my.httpRequest({
               url: that.globalData.apiurl + '/api/AliPay/GetUserInfo',
               method: 'GET',
               data: {
                  auth_code: res.authCode
               },
               dataType: 'json',
               success: function(res) {
                  that.globalData.studentid = res.data.data.student_id;
                  that.globalData.username = res.data.data.user_name;
                  //獲取用戶信息,照片、昵稱
                  my.getAuthUserInfo({
                    scopes: ['auth_user'],
                    success: (res) => {
                      that.userInfo = res;
                      resovle(that.userInfo);
                   },
                   fail:() =>{
                      reject({});
                   }
                  });
                  console.log('返回UserDetail', res.data.data);         
               },
               fail: function(res) {
                  my.alert({content: 'fail'});
               },
               complete: function(res) {
                  my.hideLoading();
               }
            });
          }
        },
        fail:() =>{
          reject({});
        }
      });
    });
  },

  onLaunch(options) {

  },
  onShow(options) {
    // 從后臺(tái)被 scheme 重新打開(kāi)
  },
});

上面的代碼調(diào)取后端webapi  http://XXX/api/AliPay/GetUserInfo 來(lái)獲取用戶信息，并把取到的userid,username 存到全局變量 globalData 里面

const app = getApp();

Page({
  data: {
    src: '',
    username: '',
    studentid: ''
  },
  imageError: function (e) {
    console.log('image 發(fā)生錯(cuò)誤', e.detail.errMsg)
  },
  imageLoad: function (e) {
    console.log('image 加載成功', e);
  },
  onLoad(query) {
    // 頁(yè)面加載
    app.getUserInfo().then(
      user => {
            console.info(user);
            //設(shè)置頭像
            if (user.avatar.length > 0) {
               this.setData({src: user.avatar});
            }
            else{
               this.setData({src: '/images/tou.png'});
            } 
            //設(shè)置用戶名    
            if (app.globalData.username)
            {
               this.setData({username: app.globalData.username});
            }
            else
            {
               this.setData({username: user.nickName});
            }

            if(app.globalData.studentid)
            {
               //設(shè)置UserId
               this.setData({studentid: app.globalData.studentid}); 
            }
        }
    );
  },
  onShow() {
    // 頁(yè)面顯示
       
  },
  onReady() {

     
  }
});

本來(lái)官方只提供了.net framwork 的SDK，但網(wǎng)上已經(jīng)有人移植了.net core 的版本，運(yùn)行 Install-Package Alipay.AopSdk.Core 進(jìn)行安裝，在 appsettings.json 進(jìn)行如下的配置，寫上你的小程序公匙，私匙，appid 等參數(shù) uid 可以不寫

  "Alipay": {
    //校園碼支付寶小程序正式環(huán)境
    "AlipayPublicKey": "",
    "AppId": "",
    "CharSet": "UTF-8",
    "GatewayUrl": "https://openapi.alipay.com/gateway.do",
    "PrivateKey": "",
    "SignType": "RSA2",
    "Uid": ""
  }

然后在后端core還需要注入Service

Startup.cs 代碼就補(bǔ)貼全部了，只貼相關(guān)的，這段代碼就干這么個(gè)事，讀取 appsettings.json  并注入服務(wù)

        private void ConfigureAlipay(IServiceCollection services)
        {
            var alipayOptions = Configuration.GetSection("Alipay").Get<AlipayOptions>();
            //檢查RSA私鑰
            AlipayConfigChecker.Check(alipayOptions.SignType, alipayOptions.PrivateKey);
            services.AddAlipay(options => options.SetOption(alipayOptions)).AddAlipayF2F();
        }


        public IConfiguration Configuration { get; }

        // This method gets called by the runtime. Use this method to add services to the container.
        public void ConfigureServices(IServiceCollection services)
        {
            //配置alipay服務(wù)
            ConfigureAlipay(services);
            ......

在得到從前端傳過(guò)來(lái)的授權(quán)碼之后，利用授權(quán)得到用戶信息

        private AlipayUserInfoShareResponse GetShareResponse(string auth_code)
        {
            var alipaySystemOauthTokenRequest = new AlipaySystemOauthTokenRequest
            {
                Code = auth_code,
                GrantType = "authorization_code"
            };
            var oauthTokenResponse = _alipayService.Execute(alipaySystemOauthTokenRequest);
            AlipayUserInfoShareRequest requestUser = new AlipayUserInfoShareRequest();
            AlipayUserInfoShareResponse userinfoShareResponse = _alipayService.Execute(requestUser, oauthTokenResponse.AccessToken);
            return userinfoShareResponse;
        }

        /// <summary>
        /// 獲取用戶信息
        /// </summary>
        /// <param name="auth_code"></param>
        /// <returns></returns>
        [HttpGet]
        [Route("GetUserInfo")]
        public ActionResult GetUserInfo(string auth_code)
        {
            try
            {
                AlipayUserInfoShareResponse userinfoShareResponse = GetShareResponse(auth_code);
                return new JsonResult(new { data = userinfoShareResponse });
            }
            catch (Exception ex)
            {
                log.Error("錯(cuò)誤:" + ex.ToString());
                return new JsonResult(new { data = ex.ToString() });
            }
        }
