php实现httpclient类示例

代码如下:

httpClient::init($httpClient, $args = null);

$httpClient->get($url, $data = null, $cookie = null);

var_dump($httpClient->buffer);

代码如下:

<?php

class httpClient {

public $buffer = null; // buffer 获取返回的字符串

public $referer = null; // referer 设置 HTTP_REFERER 的网址

public $response = null; // response 服务器响应的 header 信息

public $request = null; // request 发送到服务器的 header 信息

private $args = null;

public static function init(&$instanceof, $args = array()) {

return $instanceof = new self($args);

}

private function __construct($args = array()) {

if(!is_array($args)) $args = array();

$this->args = $args;

if(!empty($this->args['debugging'])) {

ob_end_clean();

set_time_limit(0);

header('Content-Type: text/plain; charset=utf-8');

}

}

public function get($url, $data = null, $cookie = null) {

$parse = parse_url($url);

$url .= isset($parse['query']) ? '&'. $data : ( $data ? '?'. $data : '' );

$host = $parse['host'];

$header = 'Host: '. $host. "rn";

$header .= 'DNT: 1'. "rn";

if($cookie) $header .= 'Cookie: '. $cookie. "rn";

if($this->referer) $header .= 'Referer: '. $this->referer. "rn";

$options = array();

$options['http']['method'] = 'GET';

$options['http']['header'] = $header;

$response = get_headers($url);

$this->request = $header;

$this->response = implode("rn", $response);

$context = stream_context_create($options);

return $this->buffer = file_get_contents($url, false, $context);

}

return $this->buffer = file_get_contents($url, false, $context);

}

}

httpClient::init($httpClient, array( 'debugging' => true , 'userAgent' => 'MSIE 15.0' ));

$httpClient->get('http://www.baidu.com', 'name=haowei');

echo $httpClient->request; // 获取 请求头部信息

echo $httpClient->response; // 获取 响应的头部信息
