## 需求
1. PHP 5.5.0
2. 使用PHP的流， allow_url_fopen 必须在php.ini中启用。
3. 要使用cURL，你必须已经有版本cURL >= 7.19.4，并且编译了OpenSSL 与 zlib。
>[info] ### 注解
> 如果没有安装cURL，Guzzle处理HTTP请求的时候不再使用cURL，而是使用PHP流处理，或者你也可以提供自己的发送HTTP请求的处理方式。
## 安装
推荐使用 [Composer](http://getcomposer.org/) 安装Guzzle，Composer是PHP的依赖管理工具，允许你在项目中声明依赖关系，并安装这些依赖。
> #### 安装 Composer
> curl -sS https://getcomposer.org/installer | php
你可以使用composer.phar客户端将Guzzle作为依赖添加到项目：
> php composer.phar require guzzlehttp/guzzle:^7.0
或者，你可以编辑项目中已存在的composer.json文件，添加Guzzle作为依赖：
```json
{
"require": {
"guzzlehttp/guzzle": "^7.0"
}
}
```
安装完毕后，你需要引入Composer的自动加载文件：
```php
require 'vendor/autoload.php';
```
你可以在 [getcomposer.org](http://getcomposer.org/) 发现更多关于怎样安装Composer、配置自动加载以及其他有用的东西。
## 开发版
开发期间，你也可以安装master分支下的最新内容，只需要将Guzzle版本设置成 `^7.0@dev` ：
```json
{
"require": {
"guzzlehttp/guzzle": "^7.0@dev"
}
}
```

## 贡献
### 指导方针
1. Guzzle utilizes PSR-1, PSR-2, PSR-4, and PSR-7.
2. Guzzle is meant to be lean and fast with very few dependencies. This means that not every feature request will be accepted.
3. Guzzle has a minimum PHP version requirement of PHP 7.2. Pull requests must not require a PHP version greater than PHP 7.2 unless the feature is only utilized conditionally and the file can be parsed by PHP 7.2.
4. All pull requests must include unit tests to ensure the change works as expected and to prevent regressions.
### 测试
为了做出贡献，您需要从GitHub签出源代码并使用Composer安装Guzzle的依赖项：
> git clone https://github.com/guzzle/guzzle.git
> cd guzzle && composer install
Guzzle已通过PHPUnit进行了单元测试。 使用Makefile运行测试：
> make test
>[info] ### 注解
> 您需要安装node.js v8或更高版本才能在Guzzle的HTTP处理程序上执行集成测试。
