/think-wxminihelper

基于ThinkPHP5.0的微信小程序登录流程封装。

Primary LanguagePHP

think-wxminihelper

基于ThinkPHP5.0的微信小程序composer包。

安装方法:

composer require xxh/think-wxminihelper

你只需要两部就可以实现微信的登录验证,验证成功后会自动返回一个3rd_session,和用户的基本信息

这里要注意的是,获取3rd_session因为微信官网建议Linux下面读取/dev/urandom设备, 所以这段代码只适合用于linux系统,但是如果你需要在Windows系统上测试,那么可以修改 WXLoginHelper下的randomFromDev方法

1.在config.php配置文件中加入必须的配置

// wx配置
'wx'  => [
    'url' => 'https://api.weixin.qq.com/sns/jscode2session',
    'appid' => 'wxde3ea15f3a18f7f6',
    'secret' => '53b1a4e12b88d78f3bcc2786fb72adcf',
    'grant_type' => 'authorization_code'
]

2.使用checkLogin进行验证

$code = input("code", '', 'htmlspecialchars_decode');
$rawData = input("rawData", '', 'htmlspecialchars_decode');
$signature = input("signature", '', 'htmlspecialchars_decode');
$encryptedData = input("encryptedData", '', 'htmlspecialchars_decode');
$iv = input("iv", '', 'htmlspecialchars_decode');

$wxHelper = new WXLoginHelper();
$data = $wxHelper->checkLogin($code, $rawData, $signature, $encryptedData, $iv);

当然,如果你自己有一套登录验证流程,你也可以使用decryptData进行解密验证前面的正确性

$appid = 'wx4f4bc4dec97d474b';
$sessionKey = 'tiihtNczf5v6AKRyjwEUhQ==';
