PHP 语言 使用PSR 97标准实现HTTP客户端

摘要：

随着互联网技术的发展，HTTP客户端在Web开发中的应用越来越广泛。PSR-97标准是PHP社区为了统一HTTP客户端实现而制定的一个规范。本文将围绕PSR-97标准，使用PHP语言实现一个简单的HTTP客户端，并对其关键技术进行详细解析。

一、

HTTP客户端是用于发送HTTP请求并接收响应的软件组件。在PHP中，实现HTTP客户端有多种方式，如使用cURL、file_get_contents等。这些方法往往缺乏统一性和可扩展性。为了解决这个问题，PHP社区制定了PSR-97标准，旨在提供一个统一的HTTP客户端接口。

二、PSR-97标准概述

PSR-97标准定义了一个统一的HTTP客户端接口，包括以下主要部分：

1. RequestInterface：定义了HTTP请求的接口，包括设置请求方法、URL、头部、体等。

2. ResponseInterface：定义了HTTP响应的接口，包括获取状态码、头部、体等。

3. ClientInterface：定义了HTTP客户端的接口，包括发送请求、接收响应等。

三、实现PSR-97标准的HTTP客户端

以下是一个基于PSR-97标准的PHP HTTP客户端实现示例：

```php
