封装 PHP curl http 请求 (全) Composer 安装 httpbuilder，支持 GET，POST，PUT，DELETE

composer 安装：composer require ethansmart/httpbuilder
github 地址：https://github.com/roancsu/httpbuilder

在PHP 框架中可以使用 guzzlehttp 来构建HTTP Request 服务，但是guzzle 太重了，用起来比较繁琐，所以我用curl封装了PHP HTTP Request Client，支持 GET，POST，PUT，DELETE 方法，并且对文件上传有安全检测功能等等，使用也非常简单，效率高。

Usage：

构建 HttpClient

protected $client ;
function __construct()
{
    $this->client = HttpClientBuilder::create()->build();
}

GET Request

$data = [
    'uri'=>'https://www.baidu.com'
];

return $this->client
    ->setHeaders('Content-Type:application/json')
    ->setHeaders('X-HTTP-Method-Override:GET')
    ->setHeaders('Request_id: Ethan')
    ->setTimeout(10)
    ->Get($data);

POST Request

$data = [
    'uri'=>'https://www.baidu.com',
    'params'=> [
        'user'=>ethan
     ]
];

return $this->client
    ->setHeaders('Content-Type:application/json')
    ->Post($data);

PUT 、DELETE Request

$data = [
    'uri'=>'https://www.baidu.com',
    'params'=> [
        'user'=>ethan
     ]
];

return $this->client
    ->setHeaders('Content-Type:application/json')
    ->Put($data); // Delete($data)

扩展
文件上传

Http/Client.php
但post 数据 大于1k时，设置Expect ；
