This article is about how to obtain ACCESSTOKEN .net in the development of Wechat public platform. I think it is very practical, so I share it with you. I hope you can get something after reading this article. Let's have a look with the editor.

After becoming a developer, Wechat platform will give you appid and secret, which are not available in Subscription account, so you can add menus, upload / download pictures and other functions with ACCESSTOKEN because you should apply for a service number.

Private string GetToken () {/ / can also write: / / return GetPage ("https://api.weixin.qq.com/cgi-bin/token?grant_type=client_credential&appid= your appid&secret= your secret", "); string res ="; HttpWebRequest req = (HttpWebRequest) HttpWebRequest.Create (" https://api.weixin.qq.com/cgi-bin/token?grant_type=client_credential&appid= your appid&secret= your secret ") Req.Method = "GET"; using (WebResponse wr = req.GetResponse ()) {HttpWebResponse myResponse = (HttpWebResponse) req.GetResponse (); StreamReader reader = new StreamReader (myResponse.GetResponseStream (), Encoding.UTF8); string content = reader.ReadToEnd (); List myACCESSTOKEN = Json.JSONStringToList (content); res = myACCESSTOKEN [0] .access _ token;} return res } public string GetPage (string posturl, string postData) {Stream outstream = null; Stream instream = null; StreamReader sr = null; HttpWebResponse response = null; HttpWebRequest request = null; Encoding encoding = Encoding.UTF8; byte [] data = encoding.GetBytes (postData); / / prepare the request. Try {/ / set parameters request = WebRequest.Create (posturl) as HttpWebRequest; CookieContainer cookieContainer = new CookieContainer (); request.CookieContainer = cookieContainer; request.AllowAutoRedirect = true; request.Method = "POST"; request.ContentType = "application/x-www-form-urlencoded"; request.ContentLength = data.Length; outstream = request.GetRequestStream (); outstream.Write (data, 0, data.Length) Outstream.Close (); / / send the request and get the corresponding response data response = request.GetResponse () as HttpWebResponse; / / until the request.GetResponse () program begins to send the Post request instream = response.GetResponseStream (); sr = new StreamReader (instream, encoding); / / returns the result page (html) code string content = sr.ReadToEnd (); string err = string.Empty Return content;} catch (Exception ex) {string err = ex.Message; Response.Write (err); return string.Empty;}} above is how to obtain ACCESSTOKEN .net in the development of Wechat public platform.
