附图小程序app.js：
二次更新：
编译的时候错误提示：https://api.weixin.qq.com/sns/jscode2session?appid=wx*********&secret=****37387043***&js_code=logincode&grant_type=authorization_code，这个请求地址不在安全域名列表中，官方给出的回答是为了安全起见，此接口请求只允许在服务端执行，调整后的代码如下：
服务端请求微信api获取session_key和openid代码：
1 public void RequestWxApi(string logincode) 2 { 3 string url = "https://api.weixin.qq.com/sns/jscode2session?appid=wx**********&secret=789******3e&js_code=" + logincode + "&grant_type=authorization_code"; 4 HttpWebRequest request = WebRequest.Create(url) as HttpWebRequest; 5 request.Method = "Post"; 6 7 request.ContentType = "application/json"; 8 byte[] databody = System.Text.Encoding.UTF8.GetBytes("");//发送主体 9 using (Stream stream = request.GetRequestStream()) { stream.Write(databody, 0, databody.Length); } 10 11 //获取结果 12 StreamReader srdPreview = new StreamReader(request.GetResponse().GetResponseStream()); 13 string result = srdPreview.ReadToEnd(); 14 srdPreview.Close(); 15 16 //Library.Log.WriteLogInfo("RequestWxApi", new Exception(result)); 17 18 CallBackData(true, "", result); 19 }
