[PHP知识库]laravel jwt attempt 总是返回false

在搭建JWT生成token的时候,attempt(array) 总是返回false。原因在于生成token加密方式为Hasing。

JWT的搭建在此就不多说了。网上随便搜索就有了。此教程仅仅修改token密码的验证方式

创建验签方式：

<?php

namespace App\Helper\Hasher;

use Illuminate\Contracts\Hashing\Hasher;

class MD5Hasher implements Hasher
{
    public function info($hashedValue)
    {
        // TODO: Implement info() method.
    }

    public function check($value, $hashedValue, array $options = [])
    {

        return $this->make($value) === $hashedValue;
    }

    public function needsRehash($hashedValue, array $options = [])
    {
        return false;
    }

    public function make($value, array $options = [])
    {
        $value = env('SALT', '').$value;
        //自行对password 进行加密处理  目前又前端加密， 后端直接判断password是否一致即可
        //return md5($value);
        return $value;
    }

}

创建provider.php

<?php

namespace App\Providers;

use App\Helper\Hasher\MD5Hasher;
use Illuminate\Support\ServiceProvider;
use Illuminate\Hashing\BcryptHasher;

class MD5HashServiceProvider extends ServiceProvider
{

    /**
     * Indicates if loading of the provider is deferred.
     *
     * @var bool
     */
    protected $defer = true;

    /**
     * Register the service provider.
     *
     * @return void
     */
    public function register()
    {
        $this->app->singleton('hash', function () {
            return new BcryptHasher;
        });
    }

    /**
     * Bootstrap the application services.
     *
     * @return void
     */
    public function boot()
    {
        $this->app->singleton('hash', function () {
            //加密处理
            return new MD5Hasher;
        });
    }

    public function provides()
    {
        return ['hash'];
    }
}

修改provider 方式，修改config/app.php

'providers' => [

        /*
         * Laravel Framework Service Providers...
         */
        .....
        //注释原本的加密方式
        //Illuminate\Hashing\HashServiceProvider::class,
        \App\Providers\MD5HashServiceProvider::class,
        .....
    ],

生成token

public function login()
{
    $token_info = [
        'username' => $data['username'],
        'password' => $data['password'],
   ];
   if (! $token = auth('api')->attempt($token_info)) 
        throw new ApiException("创建token 失败");
}


public function info()
{
    $token_info = auth('api')->user();
}
