weixin mini program helper

think-wxminihelper

基于ThinkPHP5.0的微信小程序composer包。, _(*1)

安装方法：, _(*2)

composer require xxh/think-wxminihelper, _(*3)

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, _(*4)

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, _(*5)

1.在config.php配置文件中加入必须的配置, _(*6)

// 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, _(*7)

$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, _(*8)
