摘要：在下新建無效無效然后在的下添加自定義的跨域中間鍵在路由和下的構造函數調用。免責由于時間關系，沒有在截圖了，參考此文章的小伙伴自行進行測試下面例子源用了很多文檔代碼

composer create-project --prefer-dist laravel/laravel sample "5.5.*"

composer install

composer require tymon/jwt-auth

or
在composer.json中添加 `"tymon/jwt-auth": "^1.0.0-rc.2",`
終端：composer update

在config/app.php的providers中

"providers" => [

    ...

    TymonJWTAuthProvidersLaravelServiceProvider::class,
]

終端運行：php artisan vendor:publish --provider="TymonJWTAuthProvidersLaravelServiceProvider"會產生config/jwt.php的配置文件

再運行：php artisan jwt:secret生成key

運行：

php artisan make:model Models/Admin -m
php artisan make:model Models/User -m

database/migrations下
遷移文件中

    **admins:**
Schema::create("admins", function (Blueprint $table) {
    $table->increments("id");
    $table->string("name");
    $table->string("email")->unique();
    $table->string("password");
    $table->string("avatar")->nullable();
    $table->timestamps();
});
    **users:**
Schema::create("users", function (Blueprint $table) {
    $table->increments("id");
    $table->string("name");
    $table->string("email")->unique();
    $table->string("password");
    $table->string("avatar")->nullable();
    $table->timestamps();
});

getKey();
    }

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

在config/auth.php中配置，找到對應的修改成自己的

"guards" => [

"web" => [
    "driver" => "session",
    "provider" => "users",
],

"api" => [
    "driver" => "jwt",
    "provider" => "users",
],

"admin" => [
    "driver" => "jwt",
    "provider" => "admins",
],

],

"providers" => [

"users" => [
    "driver" => "eloquent",
    "model" => AppModelsUser::class,
    "table" => "users",
],

"admins" => [
    "driver" => "eloquent",
    "model" => AppModelsAdmin::class,
    "table" => "admin_users"
],

],

在routes/api.php
Route::group([

"middleware" => "api",
"prefix" => "auth"

], function ($router) {

Route::post("login", "AuthController@login");
Route::post("logout", "AuthController@logout");
Route::post("refresh", "AuthController@refresh");
Route::post("me", "AuthController@me");

});

運行：php artisan make:controller AdminController創建控制器
注：此處主要是用了guard("admin")來區分要調用的表和Model這里是在auth.php中配置的

middleware("myauth", ["except" => ["login"]]);
    }

    /**
     * Get a JWT via given credentials.
     *
     * @return IlluminateHttpJsonResponse
     */
    public function login()
    {
        $credentials = request(["email", "password"]);

        if (! $token = auth()->guard("admin")->attempt($credentials)) {
            return response()->json(["error" => "Unauthorized"], 401);
        }

        return $this->respondWithToken($token);
    }

    /**
     * Get the authenticated User.
     *
     * @return IlluminateHttpJsonResponse
     */
    public function me()
    {
        return response()->guard("admin")->json(auth()->user());
    }

    /**
     * Log the user out (Invalidate the token).
     *
     * @return IlluminateHttpJsonResponse
     */
    public function logout()
    {
        auth()->guard("admin")->logout();

        return response()->json(["message" => "Successfully logged out"]);
    }

    /**
     * Refresh a token.
     *
     * @return IlluminateHttpJsonResponse
     */
    public function refresh()
    {
        return $this->respondWithToken(auth()->guard("admin")->refresh());
    }

    /**
     * Get the token array structure.
     *
     * @param  string $token
     *
     * @return IlluminateHttpJsonResponse
     */
    protected function respondWithToken($token)
    {
        return response()->json([
            "access_token" => $token,
            "token_type" => "bearer",
            "expires_in" => auth()->factory()->getTTL() * 60
        ]);
    }
}

由于使用了多表認證，所以不能使用jwt自帶的中間鍵auth:api or jwt.auth，我自己建了一個中間鍵[myauth]來做路由驗證。
在app/Http/Middleware下新建

namespace AppHttpMiddleware;

use Closure;
use IlluminateSupportFacadesAuth;

class AuthMiddleware {
    public function handle($request, Closure $next)
    {

        try {
            $user = auth()->guard("admin")->userOrFail();
            if(!$user) {
                return response()->json(["message" => "jwt 無效"], 401);
            }
        } catch (TymonJWTAuthExceptionsUserNotDefinedException $e) {
            return response()->json(["message" => "jwt 無效"], 401);
        }
        return $next($request);
    }
}

然后在app/Http/Kernel的$routeMiddleware下添加
protected $routeMiddleware = [

    ...

    "cors" => AppHttpMiddlewareClientRequestCors::class, //自定義的跨域中間鍵
    "myauth" => AppHttpMiddlewareAuthMiddleware::class,

    ...

];

在路由和Controller下的構造函數調用。
