Editor to share with you how to implement the customer service interface of the Force.com Wechat development series, I believe most people do not know much about it, so share this article for your reference, I hope you will learn a lot after reading this article, let's go to know it!

When users actively send messages to Wechat public accounts (including sending messages, clicking custom menu click events, subscription events, scanning QR code events, payment success events, user rights protection), Wechat will push the message data to developers. Developers can call the customer service message interface within a period of time (currently 48 hours) and send messages to ordinary users through a JSON packet. There is no limit on the number of times to send within 48 hours. This API is mainly used for customer service and other functions with manual message processing, making it convenient for developers to provide more quality services.

Description of call request for customer service API

The API called by the customer service API is described below (the http request method is POST). For more information on how to obtain Access Token, please see the previous description:

The customer service interface provides a huge imagination space, based on which we can develop enterprise customer service solutions. When users send support requests to Wechat public accounts, customer service personnel can receive these messages and do further processing through web pages, mobile apps, Wechat, etc., customer service personnel can also queue for children, or set users' VIP levels to provide different levels of service response speed, and so on. Build a quite intelligent customer service support system.

Send text messages to users

When you send a text message to the user, the data format is as follows:

{"touser": "OPENID", "msgtype": "text", "text": {"content": "Hello World"}}

The code for sending a text message to a user in Force.com is as follows:

Http h = new Http (); HttpRequest req = new HttpRequest (); req.setMethod ('POST'); req.setHeader (' Accept-Encoding','gzip,deflate'); req.setHeader ('Content-Type','text/xml;charset=UTF-8'); req.setHeader (' User-Agent','Jakarta Commons-HttpClient/3.1') String sendMsg ='{"touser": "ou-37t936RNZEcW0mI75RN2pdxkc", "msgtype": "text", "text": {"content": "Test customer Service message"}}'; req.setBody (sendMsg); req.setEndpoint ('https://api.weixin.qq.com/cgi-bin/message/custom/send?access_token=bW3aubvd1GVgDZbrO6zv1WGVYIU0QlEhI1J5x_NpbiouxyBc8eufzQQHHyy8cMoZmuQknz-_iEgSB76CggVTgQ');String bodyRes ='; try {HttpResponse res = h.send (req)) BodyRes = res.getBody ();} catch (System.CalloutException e) {System.debug ('Callout error:' + e); ApexPages.addMessage (new ApexPages.Message (ApexPages.Severity.FATAL, e.getMessage ());})
