Detailed explanation of asp.net WeChat development message response method

When an ordinary WeChat user sends a message to a public account, the WeChat server will POST the XML data packet of the message to the URL filled in by the developer.

Please note:

The push XML data packet structure of each message type is as follows:

Please note that after enabling voice recognition, every time the user sends a voice to the official account, WeChat will add a Recongnition field (Note: Due to client caching, developers can turn on or off the speech recognition function, which will take effect immediately for new followers and take 24 hours for already followed users. Developers can re-follow this account for testing). The voice XML data packet after enabling voice recognition is as follows:

In the extra fields, Format is the voice format, usually amr, and Recognition is the voice recognition result, using UTF8 encoding.

The speech recognition function is turned on as follows:

requestXML is one I created separately Class, which declares the commonly used attribute fields in messages, as follows:

Continue to follow ResponseMsg(requestXML);The method is as follows,

Break;

Case "EVENT": // Send the event

if (! String.isnullWhitespace (Requestxml. EventName ) && requestXML.EventName.ToString().Trim().Equals("subscribe"))

                                                                                                }

                                                                                                   if (!string.IsNullOrWhiteSpace(requestXML.EventName) && requestXML.EventName.ToString().Trim().Equals("CLICK"))
                                                                 );//Send event message
                                    
                                                                                                                      

　　 　 case "voice":
　　 　　 SendVoiceMsg(requestXML);//Send a voice message                       SendMapMsg(requestXML);
break;
                                 
                                        break; {
    HttpContext.Current.Response.Write(ex.ToString());
                                                                                                                        Send text
                                                                       #            string responseContent = FormatTextXML(requestXML.FromUserName, requestXML.ToUserName, requestXML.Content); HttpContext.Current.Response.ContentEncoding = Encoding.UTF8 ;
                HttpContext.Current.Response.Write(responseContent);
                                                                                             

///

In this way, the response to the message can be realized. If the user clicks the button, the following code:

case "event"://Send event message
If (!string.IsNullOrWhiteSpace(requestXML.EventName) && requestXML.EventName.ToString().Trim().Equals("subscribe"))

                                                                                                                                                                                 else if (!string.IsNullOrWhiteSpace(requestXML.EventName) && requestXML.EventName.ToString().Trim().Equals("CLICK"))
