Asp.net WeChat developer access skills

This article mainly introduces the developer access content in asp.net development. if you need it, refer to the following article to introduce the developer access content in asp.net development, for more information, see

First, let's take a look at the operations on the project:

Public void ProcessRequest (HttpContext context) {context. response. contentType = "text/plain"; string postString = string. empty; if (HttpContext. current. request. httpMethod. toUpper () = "POST") {using (Stream stream = HttpContext. current. request. inputStream) {Byte [] postBytes = new Byte [stream. length]; stream. read (postBytes, 0, (Int32) stream. length); postString = Encoding. UTF8.GetString (postBytes) ;} If (! String. isNullOrEmpty (postString) {ResponseXML (postString); // return the user information} // load the custom menu string postData = "{" + "\ r \ n "; postData + = "\" button \ ": [" + "\ r \ n"; postData + = "{" + "\ r \ n "; postData + = "\" name \ ": \" simple query \ "," + "\ r \ n"; postData + = "\" sub_button \": ["+" \ r \ n "; postData + =" {"+" \ r \ n "; postData + =" \ "type \": \ "click \", "+" \ r \ n "; postData + =" \ "name \": \ "My salary \", "+" \ r \ n "; postData + = "\" key \ ": \" mypay \ "" + "\ r \ n"; postData + = "}," + "\ r \ n "; postData + = "{" + "\ r \ n"; postData + = "\" type \ ": \" click \ "," + "\ r \ n "; postData + = "\" name \ ": \" weather forecast \ "," + "\ r \ n"; postData + = "\" key \": \ "tianqiyubao \" "+" \ r \ n "; postData + ="}, "+" \ r \ n "; postData + = "{" + "\ r \ n"; postData + = "\" type \ ": \" view \ "," + "\ r \ n "; postData + = "\" name \ ": \" train ticket query \ "," + "\ r \ n"; postData + = "\" url \":\" http://www.deqiaohr.com.cn/ *******.
