微信小程序链接ASP.NET Webapi获取openid

在创建项目时，需要使用自己的appid，不能使用测试号的appid

首先在app.js文件中找到  wx.login({})，在里面调用一下asp.net webapi接口

if(res.code)

        {

          console.log('获取用户登录凭证：'+res.code);

           wx.request({

             url: 'http://localhost:52384/api/values/WX?js_code='+res.code, //传值

             headers:{

               'Content_Type':'application/json'

             },

             success: function (res) {

               console.log('获取openid:'+res.data); 

             }

           })

        }

 

 

后端代码

public string GetWX(string js_code)//获取前端传过来的值
{
string url= "https://api.weixin.qq.com/sns/jscode2session?appid=自己的appid&secret=自己的secret&js_code=" + js_code + "&grant_type=authorization_code";
HttpWebRequest request = (HttpWebRequest)WebRequest.Create(url);
request.Method = "GET";
request.ContentType = "text/html;charset=UTF-8";
HttpWebResponse response = (HttpWebResponse)request.GetResponse();
Stream myResponseStream = response.GetResponseStream();
StreamReader myStreamReader = new StreamReader(myResponseStream, Encoding.UTF8);
string retString = myStreamReader.ReadToEnd();
myStreamReader.Close();
myResponseStream.Close();
return retString;
}

 

最后返回的结果是
