Laravel 5.6 Method Illuminate\Database\Query\Builder::createToken does not exist
提问by condo1234
I am trying to create API authentication using Passport but I can not seem to create a token when a user is being registered using createToken().
我正在尝试使用 Passport 创建 API 身份验证，但是当使用createToken()注册用户时，我似乎无法创建令牌。
I have already checked I have included HasApiTokens but still gives same error.
我已经检查过我已经包含了 HasApiTokens 但仍然给出相同的错误。

You need to fetch the user. Currently $user is the QueryBuilder, not the user object.
您需要获取用户。目前 $user 是 QueryBuilder，而不是用户对象。
User::where('email', $email)->where('password', $password)->first();
User::where('email', $email)->where('password', $password)->first();

You need to add the methods like get()or first()or 'firstOrFail()' to get the database result. all the wherechains just return the QueryBuilder's object. Second thing is that you won't be saving the password as plain text (if you are saving so then please change it and hashed it before saving). For your case, it would become:
您需要添加诸如get()orfirst()或 'firstOrFail()' 之类的方法来获取数据库结果。所有的where链都只返回QueryBuilder的对象。第二件事是您不会将密码保存为纯文本（如果您正在保存，那么请在保存之前更改它并对其进行哈希处理）。对于您的情况，它将变为：
$user = User::where('email' , $email)->where( 'password' , $password)->first();
In the scenario of hashed password:
在散列密码的情况下：
$user = User::where('email' , $email)->first();
if(Hash::check(optional($user)->password, $request->password)) {
// your code here
}
