laravel - 在 null 上调用成员函数 createToken()？

Question

我用passport包的时候遇到这个错误

Call to a member function createToken() on null

为什么我会收到这个错误？

这是我的代码:

$users = Users::where('Email' , $username)
              ->where( 'Password' , $password)
              ->where('UserStatus' , config('global.active'))
              ->first();

if($users) {
    $success['token'] =  $users->createToken('MyApp')->accessToken;
    return response()->json(['success' => $success], $this->successStatus);
} else {
    return response()->json(['error'=>'Unauthorised'], 401);
}

Answer 1

$user = Auth::user();是不必要的，是导致您错误的原因。

$user = Users::where('Email' , $username)->where( 'Password' , $password)->where('UserStatus' , config('global.active'))->first();
if($user){
    $success['token'] =  $user->createToken('MyApp')->accessToken;
    return response()->json(['success' => $success], $this->successStatus);
}else{
    return response()->json(['error'=>'Unauthorised'], 401);
}
