This article mainly introduces "how to implement message interface verification and message interface response on Wechat public platform". In daily operation, it is believed that many people have doubts about how to implement message interface verification and message interface response on Wechat public platform. The editor consulted all kinds of materials and sorted out simple and easy-to-use operation methods. I hope it will be helpful for you to answer the doubt of "how to implement the message interface verification and message interface response of Wechat public platform". Next, please follow the editor to study!

The specific analysis is as follows:

In the process of developing the message interface of Wechat public platform, we first need to verify the validity of the message interface, and then we can carry out other development after verification. First of all, let's take a look at the PHP SDK given to me by Wechat public platform.

1. You need to set a TOKEN message as follows:

The copy code is as follows:

Efine ("TOKEN", "weixin")

This TOKEN message can be set by the developer.

2. There is a wechatCallbackapiTest class, which contains three methods: valid, responseMsg, checkSignature, in which the methods valid and checkSignature are used to verify the validity of the interface URL, and responseMsg is the most frequently used method. Most of the subsequent development work will be completed here.

After we verify the validity of the interface, we no longer need to verify, then we need to use the responseMsg method, so how to ensure that after the verification of the interface, there is no need to switch methods or modify the code?

Here's what I did, with the code as follows:

The copy code is as follows:

Public function indexAction ()

{

If (isset ($_ GET ['echostr']))

{

$echoStr = $_ GET ["echostr"]

/ / valid signature, option

If ($this- > checkSignatureAction ())

{

Echo $echoStr

Exit

}

}

Else

{

$this- > responseMsgAction ()

}

Return FALSE

}

Explain: because an echostr parameter is passed when verifying the validity of the interface, but not in the response process of the message interface, we use this parameter to determine whether to verify the interface or the interface response. The code is as follows:

The copy code is as follows:

Isset ($_ GET ['echostr'])

At this point, the study on "how to implement the message interface verification and message interface response of Wechat public platform" is over. I hope to be able to solve your doubts. The collocation of theory and practice can better help you learn, go and try it!
