c#写一个获取微信小程序 openid和session_key 的方法。。
1，微信小程序端
// 登录
wx.login({
success: res => {
// 发送 res.code 到后台换取 openId, sessionKey, unionId
console.log(res.code);
wx.request({
url: 'http://localhost:10000/getcode/getcode/',
data:{
'json_code': res.code
},
method: 'GET',
header: {
'content-type': 'application/x-www-form-urlencoded',
},
success:function(res){
console.log(res.data.data)
}
})
}
})
2，c#后台
#region 获取小程序openid 和session_key
[HttpGet]
public void GetCode(string json_code)
{
string serviceAddress = "https://api.weixin.qq.com/sns/jscode2session?appid=" + "APPID" + "&secret="
+ "APPSECRET" + "&js_code=" + json_code + "&grant_type=authorization_code";
HttpWebRequest request = (HttpWebRequest)WebRequest.Create(serviceAddress);
request.Method = "GET";
request.ContentType = "text/html;charset=utf-8";
HttpWebResponse response = (HttpWebResponse)request.GetResponse();
Stream myResponseStream = response.GetResponseStream();
StreamReader myStreamReader = new StreamReader(myResponseStream, System.Text.Encoding.UTF8);
string retString = myStreamReader.ReadToEnd();
myStreamReader.Close();
myResponseStream.Close();
var obj = new
{
data = retString,
Success = true
};
Formatting microsoftDataFormatSettings = default(Formatting);
string result = JsonConvert.SerializeObject(obj, microsoftDataFormatSettings);
Response.Write(result);
}
#endregion
然后就完成了。。。
