【问题描述】：

希望你做得很好。 ;)

但是，我在生成 JWT Auth Token 时遇到了问题

我们有一个名为 somename_users 的自定义用户表，其中电子邮件字段名为 email_id，我们使用 md5 哈希来存储密码（不要判断）。所以首先我尝试做一些测试，它成功了，我成功生成了 JWT 身份验证令牌，所以之后，我试图在我们的开发服务器上实现它。

App\Model\User.php

<?php

namespace App\Model;

use Tymon\JWTAuth\Contracts\JWTSubject;
use Illuminate\Contracts\Auth\MustVerifyEmail;
use Illuminate\Foundation\Auth\User as Authenticatable;
use Illuminate\Notifications\Notifiable;

class User extends Authenticatable implements JWTSubject

    use Notifiable;

    const CREATED_AT = 'created_at';
    const UPDATED_AT = 'modified_at';

    /**
     * The attributes that are mass assignable.
     *
     * @var array
     */
    protected $fillable = [
        'first_name','middle_name','last_name','email_id','password',[...]
    ];

    /**
     * The attributes that should be hidden for arrays.
     *
     * @var array
     */
    protected $hidden = [
        'password'
    ];


    /**
     * Get the identifier that will be stored in the subject claim of the JWT.
     *
     * @return mixed
     */
    public function getJWTIdentifier()
    
        return $this->getKey();
    

    /**
     * Return a key value array, containing any custom claims to be added to the JWT.
     *
     * @return array
     */
    public function getJWTCustomClaims()
    
        return [];

每次我尝试使用电子邮件和密码登录 API 端点时，都会收到未经授权的响应，但凭据绝对完美。

请帮帮我。

【参考方案1】：

laravel 密码登录尝试使用bcrypt 而不是md5，因此必须更改您的代码。

TestController.php

    public function __construct()
    
        ...
        $this->guard = "api"; // add
    

    public function login(Request $request)
    
        $validator = Validator::make($request->all(), [
            'email_id' => 'required|string',
            'password' => 'required|string',
        ]);

        if ($validator->fails()) 
            return response()->json($validator->errors(), 422);
        

        $user = \App\User::where([
            'email_id' => $request->email_id,
            'password' => md5($request->password)
        ])->first();
