URL和Token

url地址这里需要自己有服务器，没有服务器的可以使用内网穿透工具如下:

Token验证代码

    //1. 将timestamp , nonce , token 按照字典排序
    $timestamp = $_GET['timestamp'];
    $nonce = $_GET['nonce'];
    $token = "ceshi";#你自定义的Token值 用于验证
    $signature = $_GET['signature'];
    $array = array($timestamp,$nonce,$token);
    sort($array);
    
    //2.将排序后的三个参数拼接后用sha1加密
    $tmpstr = implode('',$array);
    $tmpstr = sha1($tmpstr);
    
    //3. 将加密后的字符串与 signature 进行对比, 判断该请求是否来自微信
    if($tmpstr == $signature)
    {
        echo $_GET['echostr'];
        exit;
    }

网页授权登录

授权登录代码demo

使用了composer包
地址：https://packagist.org/packages/yurunsoft/yurun-oauth-login

index.php

<?php
require 'vendor/autoload.php';
use Yurun\OAuthLogin\Weixin;

session_start();
$obj = new Weixin\OAuth2('wxcd9aec1397657647','8d31cb9e1645abbac90327ef757508ec','http://zouzhanhao.utools.club/callback.php');
$url = $obj->getWeixinAuthUrl();
$_SESSION['YURUN_QQ_STATE'] = $obj->state;
header('location:' . $url);

callback.php

<?php
    require 'vendor/autoload.php';
    use Yurun\OAuthLogin\Weixin;
    
    session_start();
    $obj = new Weixin\OAuth2('wxcd9aec1397657647','8d31cb9e1645abbac90327ef757508ec','http://zouzhanhao.utools.club/callback.php');
    $data = $obj->getAccessToken($_SESSION['YURUN_QQ_STATE'],$_GET['code'],$_GET['state']);
    $userInfo = $obj->getUserInfo();
    $openid = $obj->openid;
    var_dump($userInfo);
