Laravel集成Facebook登录时跳过登录表单直接重定向至回调URL问题

问题详情 #

• Laravel网站触发Facebook登录时，未加载Facebook登录表单，直接重定向至.env配置的回调URL
• 使用Postman调用同一重定向接口 facebookRedirect（地址：https://www.cheerzclub.com/auth/facebook），能正常返回Facebook登录页面
• 回调接口地址：https://www.cheerzclub.com/auth/facebook/callback

控制器代码 #

class SocialController extends Controller
{
    public function facebookRedirect()
    {
        return Socialite::driver('facebook')->redirect();
    }
    
    public function loginWithFacebook(Request $r)
    {
        if (!$r->has('code') || $r->has('denied')) {
            return redirect('/');
        }
        try {
            $user = Socialite::driver('facebook')->user();
        } catch (Exception $e) {
            $user = Socialite::driver('facebook')->stateless()->user();
        }
        
        $isUser = User::where('fb_id', $user->id)->first();
        if (!$isUser)
            $isUser = User::where('email', $user->email)->first();
        if (!$isUser)
            $isUser = User::where('email', $user->id)->first();
        if ($isUser) {
            Auth::login($isUser);
            return redirect('/dashboard');
        } else {
            $createUser = User::create([
                'name' => $user->name,
                'email' => $user->email ? $user->email : $user->id,
                'fb_id' => $user->id,
                'email_verified_at' => now(),
                'password' => Hash::make('SLogin#123')
            ]);
            Auth::login($createUser);
            return redirect('/dashboard');
        }
    }
}
