2021-05-17 laravel + EasyWechat

1. 安装必要的第三方包

$ composer require overtrue/wechat:~5.0 -vvv

2.修改config/auth.php中的 providers

    'providers' => [
        'users' => [
            'driver' => 'eloquent',
            'model' => App\Models\Member\Members::class,
            // 这个根据项目设置, 我这里的用户表用的是member所以这里的模型需要换成对应的Members类
        ],

        // 'users' => [
        //     'driver' => 'database',
        //     'table' => 'users',
        // ],
    ],

3. 在控制器中添加用户验证方法

    public function officialAccounts(Request $request)
    {
        // 已登录
        if (Auth::check()) {
            return redirect(route('user'));
        }
        $config = [
            'app_id' => Configs::where('key', 'APP_ID')->value('value'),
            'secret' => Configs::where('key', 'SECRET')->value('value'),
            'response_type' => 'array',
            'oauth' => [
                'scopes'   => ['snsapi_base'], 
                 // 静默获取  snsapi_base   点击按钮用户信息   snsapi_userinfo 
                'callback' => route('auth.official_account_to_notify'),
            ],
        ];

        $app = Factory::officialAccount($config);
        $oauth = $app->oauth;
        return $oauth->redirect();

    }

4. 在控制器中写入回调方法

    public function officialAccountToNotify(Request $request)
    {
        $config = [
            'app_id' => Configs::where('key', 'APP_ID')->value('value'),
            'secret' => Configs::where('key', 'SECRET')->value('value'),
            'response_type' => 'array',
        ];

        $app = Factory::officialAccount($config);
        $user = $app->oauth->user()->toArray();
        $openid = $user['original']['openid'];
        // 拿到静默获取的openid, 静默获取只能获取openid   点击按钮可以获取详细信息
        $user = $app->user->get($openid);
        // 通过openid获取用户信息, 若是显性按钮获取可省略这一步
        $user = Members::UpdateOrCreate(['openid' => $openid], [
            'openid' => $openid,
            'nickname' => $user['nickname'],
//            'gender' => $user['gender'],
//            'city' => $user['city'], // 'Wenzhou',
//            'province' => $user['province'], // 'Zhejiang',
//            'country' => $user['country'], // 'China',
            'avatar' => $user['headimgurl'],
//            'subscribe_time' => $user['subscribe_time'],
            'mobile' => '--',
            'login_time' => date('Y-m-d H:i:s'),
        ]);

        \Auth::login($user);

        return redirect(route('member'));
    }

5.在路由文件中添加对应路由

    Router::get('/wechat/official_accounts', 'WechatController@officialAccounts');
    Router::any('/wechat/official_account_to_notify', 'WechatController@officialAccountToNotify')
        ->name('auth.official_account_to_notify');
