1、小程序後臺認證
小程序界面點擊授權登錄獲取code,傳遞給後臺,後臺調用如下接口
public async Task<WxResult> AuthenticationAsync(string code) { var appId = ConfigurationManager.AppSettings["WeChat:Appid"]; var appSecret = ConfigurationManager.AppSettings["WeChat:Secret"]; var url = $"https://api.weixin.qq.com/sns/jscode2session?appid={appId}&secret={appSecret}&js_code={code}&grant_type=authorization_code"; var webRequest = WebRequest.CreateHttp(url); webRequest.Method = "Get"; var webResponse = (HttpWebResponse)webRequest.GetResponse(); if (webResponse.StatusCode == HttpStatusCode.OK) { using (var stream = webResponse.GetResponseStream()) { using (var reader = new StreamReader(stream)) { string content = await reader.ReadToEndAsync(); var result=JsonConvert.DeserializeObject<WxAuthenticationResultModel>(content); if(string.IsNullOrEmpty(result?.openid)) return new WxAuthenticationFailedResult("微信接口openid爲空"); return new WxAuthenticationSucceedResult() { OpenId = result.openid }; } } } else { return new WxAuthenticationFailedResult("微信接口調用失敗"); } }
注意:首先要有開發者權限,其次是有appid和appsecret(管理後臺獲得)
