How to implement WeChat login in phpcms?

phpcms implements WeChat login (no registration required, direct deposit)

Idea: callback parameters, register directly (the code is not standardized enough, organize it yourself)

At the root Create a new directory wechat.php

Visit: http://www.xxxxxx.cn/wechat.php

Note the callback address

phpcms implements WeChat login (no registration required, directly Deposit)

wechat.php

<?php
if(!empty( $_GET[&#39;code&#39;]) && !empty( $_GET[&#39;state&#39;])){
    $code = $_GET[&#39;code&#39;];
    $state = $_GET[&#39;state&#39;];
    $url = "http://www.xxxxxx.cn/index.php?m=member&c=index&a=wechat&code=$code&state=$state";
    header(&#39;location:&#39;.$url);
    exit;
}
$appid = &#39;wx5a3878682fa32bd5&#39;;
$url = "https://open.weixin.qq.com/connect/qrconnect?appid=$appid&redirect_uri=http://www.xxxxxx.cn/wechat.php&response_type=code&scope=snsapi_login&state=1&connect_redirect=1#wechat_redirect";
header(&#39;location:&#39;.$url);
?>

\phpcms\modules\member\index.php and add

Note: The registration status output $status, you can return error information according to Error message modification parameter content

The user name and password are simply distinguished and modified according to the actual situation. The email address is a required field, so just put one in it.
