What is Laravel Passport?

Laravel 護照是什麼？

Laravel Passport is a powerful authentication package designed specifically for Laravel, a PHP web framework. It provides a simple and elegant way to create RESTful APIs and manage authentication for your Laravel applications. With Laravel Passport, you can easily generate access tokens, refresh tokens, and personal access clients, allowing you to control and customize the authentication process for your application.

Laravel Passport 是一個強大的身份驗證包，專為 PHP Web 框架 Laravel 設計。它提供了一種簡單而優雅的方式來創建 RESTful API 並管理 Laravel 應用程式的身份驗證。使用 Laravel Passport，您可以輕鬆產生存取權杖、刷新令牌和個人存取用戶端，從而允許您控制和自訂應用程式的身份驗證流程。

對 RESTful API 的開箱即用支援：Laravel Passport 與 Laravel 的 RESTful API 功能無縫集成，為產生存取權杖和管理 API 驗證提供內建支援。

Simple and intuitive interface: Laravel Passport's API is straightforward and easy to use, enabling developers to quickly create and manage access tokens, refresh tokens, and personal access clients with minimal effort.

簡單直覺的介面：Laravel Passport 的 API 簡單易用，使開發人員能夠以最少的工作快速建立和管理存取權杖、刷新令牌和個人存取用戶端。

Granular control over authentication: Laravel Passport provides fine-grained control over the authentication process, allowing you to customize the token lifetime, token scopes, and client authorization rules to suit the specific needs of your application.

對身份驗證的精細控制：Laravel Passport 提供對身份驗證過程的細微控制，讓您可以自訂令牌生命週期、令牌範圍和用戶端授權規則，以滿足應用程式的特定需求。

Integration with Laravel's authorization system: Laravel Passport integrates seamlessly with Laravel's authorization system, providing a comprehensive and unified approach to managing both authentication and authorization in your application.

與 Laravel 的授權系統整合：Laravel Passport 與 Laravel 的授權系統無縫集成，提供全面且統一的方法來管理應用程式中的身份驗證和授權。

Creating a Laravel application

創建 Laravel 應用程式

To begin, let's create a new Laravel application by following these steps:

首先，讓我們按照以下步驟建立一個新的 Laravel 應用程式：

Open your terminal or command prompt and navigate to the desired directory where you want to create the Laravel application.

開啟終端機或命令提示字元並導航至要在其中建立 Laravel 應用程式的所需目錄。

Run the following command to create a new Laravel application named "passport-demo":

執行以下命令建立一個名為「passport-demo」的新 Laravel 應用程式：

composer create-project laravel/laravel passport-demo

作曲家創建專案 laravel/laravel 護照演示

This command will create a new Laravel application directory called "passport-demo" and install all the necessary dependencies.

此命令將建立一個名為「passport-demo」的新 Laravel 應用程式目錄並安裝所有必要的依賴項。

Once the application is created, navigate into its directory by running the following command:

建立應用程式後，透過執行以下命令導航至其目錄：

cd passport-demo

Configuring Laravel Passport

配置 Laravel Passport

Now that we have a Laravel application, let's configure Laravel Passport to enable its features in our application. To do this, follow these steps:

現在我們有了一個 Laravel 應用程序，讓我們配置 Laravel Passport 以在我們的應用程式中啟用其功能。為此，請按照下列步驟操作：

Within the "passport-demo" application directory, run the following command to install Laravel Passport:

在「passport-demo」應用程式目錄中，執行以下命令來安裝 Laravel Passport：

composer require laravel/passport

作曲家需要 laravel/passport

After installing Laravel Passport, publish its migrations and configuration by running the following command:

安裝 Laravel Passport 後，透過執行以下命令發布其遷移和配置：

php artisan passport:install

php artisan 護照：安裝

This command will publish the Laravel Passport migrations and configuration to your application.

此命令會將 Laravel Passport 遷移和配置發佈到您的應用程式。

Next, let's create the database tables required by Laravel Passport by running the following command:

接下來，讓我們透過執行以下命令來建立 Laravel Passport 所需的資料庫表：

php artisan migrate

php 工匠遷移

Now, Laravel Passport is fully configured and ready to be used within your Laravel application.

現在，Laravel Passport 已完全配置並可在您的 Laravel 應用程式中使用。

Creating access tokens with Laravel Passport

使用 Laravel Passport 建立存取令牌

Laravel Passport provides a convenient method called createToken to generate access tokens for your application. Here's how you can use it:

Laravel Passport 提供了一種名為 createToken 的便捷方法來為您的應用程式產生存取權杖。使用方法如下：

In the User model of your Laravel application, add the following code to create an access token:

在 Laravel 應用程式的使用者模型中，新增以下程式碼來建立存取權杖：

// Create a new access token.

// 建立一個新的存取令牌。

public function createToken($name, $abilities = ['*'])

公用函數 createToken($name, $powered = ['*'])

{

$token = $this->tokens()->create([

$token = $this->tokens()->create([

'name' => $name,

'名稱' => $名稱，

'token' => Str::random(60),

'令牌' => Str::隨機(60),

'abilities' => $abilities,

'能力' => $能力，

]);

]);

return new AccessToken($token);

返回新的 AccessToken($token);

}

Once you've added the createToken method to the User model, you can use it to generate access tokens in your controllers or routes. For example, in a controller method, you can create an access token like this:

將 createToken 方法新增至 User 模型後，您可以使用它在控制器或路由中產生存取權杖。例如，在控制器方法中，您可以建立以下存取令牌：

// Create an access token for the user.

// 為使用者建立存取令牌。

$token = $user->createToken('MyAccessToken', ['view-posts', 'edit-posts']);

$token = $user->createToken('MyAccessToken', ['view-posts', 'edit-posts']);

In this example, we're creating an access token named "MyAccessToken" and assigning it two abilities: "view-posts" and "edit-posts". You can customize the name and abilities of the access token to fit your application's needs.

在此範例中，我們建立一個名為「MyAccessToken」的存取令牌，並為其指派兩種功能：「檢視貼文」和「編輯貼文」。您可以自訂存取權杖的名稱和功能以滿足您的應用程式的需求。

Creating personal access clients with Laravel Passport

使用 Laravel Passport 建立個人存取用戶端

Laravel Passport also allows you to create personal access clients, which can be used to generate access tokens without user interaction. Here's how you can create a personal access client:

Laravel Passport 還允許您建立個人存取用戶端，可用於產生存取權杖而無需使用者互動。以下是建立個人存取用戶端的方法：

In the PersonalAccessTokenClient model of your Laravel application, add the following code to create a personal access client:

在 Laravel 應用程式的 PersonalAccessTokenClient 模型中，新增以下程式碼以建立個人存取用戶端：

// Create a new personal access client.

// 建立一個新的個人存取用戶端。

public function createToken($name, $abilities = ['*'])

公用函數 createToken($name, $powered = ['*'])

{

$token = $this->tokens()->create([

$token = $this->tokens()->create([

'name' => $name,

'名稱' => $名稱，

'token' => Str

'令牌' => 字串
