PHPCMS实现微信登录：快速集成与优化指南

phpcms实现微信登录的方法：1、在根目录新建“wechat.php”；2、在“\phpcms\modules\member\index.php”下增加“public function wechat() {...}”；3、在“foreground.class.php”文件中通过wechat函数判断用户是否登录即可。

本教程操作环境：Windows10系统、phpcms v9版，DELL G3电脑

phpcms怎么实现微信登陆？

phpcms实现微信登陆（无需注册，直接存入） 

思路：回调参数，直接register (代码不够规范，自己整理)

在根目录新建wechat.php 

访问： http://www.xxxxxx.cn/wechat.php

注意回调地址 

phpcms实现微信登陆（无需注册，直接存入）

wechat.php

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

\phpcms\modules\member\index.php下增加

注：注册状态输出 $status， 可以返回错误信息 根据错误信息修改参数内容

用户名称和密码做了简单区别处理，根据实际情况修改，邮箱为必须字段，随便放了一个。
