This article describes the method of authentication of developers on the php version of WeChat public platform. Share it for your reference, as follows:
How to become a developer on WeChat public platform?
After logging into the WeChat public platform, click Advanced Function =》Development Mode =》Become a developer =》Fill in the interface configuration information, and wait for review by our staff after submitting.
1. Developer certification
This is the simplest, just put the super simple version of the code:
exit($_GET['echostr']);
Just write the above sentence for the php file. Fill in the token on WeChat public platform, write the url of the php file, and then verify it and pass it. It's super simple? Official authentication is not necessary at all, because the subsequent steps do not use the verification signature, so this place can be directly outputted and passed the verification easily for the convenience of the picture. Of course, the official authentication code is also given below:
$token='11';
$signarr=array($token,$_GET['timestamp'],$_GET['nonce']);
if($this->signnature($signarr,$_GET['signature'])){
exit($_GET['echostr']);
}
function signnature($arr,$signature){
sort($arr);
if(sha1(implode($arr))==$signature) return true;
return false;
}
Save the above code into a php file, set the same token on the WeChat public platform, and then verify it and pass.
Note: url is allowed to take get parameters
2. Website access:
After the public platform users submit information, we will request it to the filled-in URL through GET request, and bring four parameters:
* signature — WeChat encryption signature
* timestamp — timestamp
* nonce — random number
* echostr — random string
The developer checks the legitimacy of the URL access by checking the signature. If the GET request returns the echostr parameter content as it is, the access takes effect. Otherwise, the access fails. Verification Signature will combine the token parameters, timestamp parameters and nonce parameters filled in by the developer.
3. Encryption process:
* Sort dictionary order by token, timestamp, and nonce
* Splice three parameter strings into one string for sha1 encryption
* The strings obtained by the developer can be compared with signature, identifying that the request comes from WeChat.
