This article mainly shows you the "example analysis of Wechat messages sent by Wechat developers", which is easy to understand and well-organized. I hope it can help you solve your doubts. Next, let the editor lead you to study and study the "sample analysis of Wechat messages developed by Wechat".

1. First of all, obtain the developer test account (application) and generate the test account based on the account provided by the current scan code: link address: http://mp.weixin.qq.com/wiki/home/index.html

At this point, you can get the appid and appsecrept for the test, and then call the API to obtain the credential and call the API to obtain the access_token.

2. Information sending is described below, which simulates single-user information sending and multi-user message batch sending.

(1) basic method, http method

/ http get/post public method / request link / request parameter value (in the case of get, the default is "") / request method post or get/ public static string Request (this string requestUrl, string requestMethod) String requestJsonParams = "") {string returnText = "" StreamReader streamReader = null; HttpWebRequest request = null; HttpWebResponse response = null; Encoding encoding = Encoding.UTF8; request = (HttpWebRequest) WebRequest.Create (requestUrl); request.Method = requestMethod; if (! string.IsNullOrEmpty (requestJsonParams) & & requestMethod.ToLower () = = "post") {byte [] buffer = encoding.GetBytes (requestJsonParams) Request.ContentLength = buffer.Length; request.GetRequestStream () .Write (buffer, 0, buffer.Length);} try {response = (HttpWebResponse) request.GetResponse () Using (streamReader = new StreamReader (response.GetResponseStream (), System.Text.Encoding.GetEncoding ("gb2312")) / / utf-8 {returnText = streamReader.ReadToEnd ();}} catch (Exception ex) {returnText = ex.Message;} return returnText }

(2) simulated transmission:

/ / send Wechat messages (sent by a single user) / Authorization Code (Wechat token) / send Information Model / public static string SendSingleMessage (WeChatParamEntity messageInfo, string access_token) {messageInfo.MsgType = string.IsNullOrEmpty (messageInfo.MsgType)? "text": messageInfo.MsgType; string jsonDataParams = messageInfo = = null? "": JsonConvert.SerializeObject (new {touser = messageInfo.ToUser, msgtype = messageInfo.MsgType, text = new {content = messageInfo.Text}}); string requestUrl = string.Format (Consts.URL_POSTSINGLETEXTMESSAGE, access_token) Return requestUrl.Request ("POST", jsonDataParams) } / send Wechat messages (sent by multiple users in batches) / Authorization code (Wechat token) / send information model / public static string SendMessages (WeChatParamsEntity messageInfo, string access_token) {messageInfo.MsgType = string.IsNullOrEmpty (messageInfo.MsgType)? "text": messageInfo.MsgType; string jsonDataParams = messageInfo = = null? "": JsonConvert.SerializeObject (new {touser = messageInfo.ToUser, msgtype = messageInfo.MsgType, text = new {content = messageInfo.Text}}); string requestUrl = string.Format (Consts.URL_POSTTEXTMESSAGES, access_token) Return requestUrl.Request ("POST", jsonDataParams);

(3) two parameter models:

/ Wechat sends information parameters entity model / public class WeChatParamEntity {/ ordinary user openid / public string ToUser {get; set } / File type transferred (text,image, and so on) / public string MsgType {get; set;} = "text"; / transfer text content / public string Text {get; set }} Universe / Wechat sends information parameters entity model / public class WeChatParamsEntity {/ ordinary user openid / public string [] ToUser {get; set File type transferred (text,image, and so on) / public string MsgType {get; set;} = "text"; / transfer text content / public string Text {get; set;}}

(4) links in web.config

3. The test uses this parameter related to touser, which is the openID of the object to be sent. This is very simple, which is obtained in the developer documentation (that is, step 2 above).

When appid and appsecrept, there is a QR code at the bottom of the current page. Find a few people to scan with Wechat and you can automatically get the openID. In this case, put the parameters into the script simulation.

Post is fine.

It is also important to note that the format of json parameters prompted in the document

Note 3: the token validity time is 7200, two hours. You need to judge the token validity of the current user sending messages. At the same time, the maximum number of requests per day is 2000.

Get token:

# region gets token and verifies token expiration time public static string GetAccessToken (string appid, string appSecret) {string token = ""; string requestUrl = string.Format (ConfigBLL.URL_GETACCESSTOKEN, appid, appSecret); string requestResult = WebAPITransfer.Request (requestUrl, "GET", ""); CommonBLL.DebugLog (requestResult, "AccessToken-token-Params") String [] strArray = requestResult.Split (','); token = strArray [0] .split (':') [1] .replace ("\", "); return token;} # endregion is all the content of the article" sample Analysis of Wechat messages sent by Wechat developer ".
