php实现httpclient类示例

　　这篇文章主要介绍了php实现httpclient类示例,需要的朋友可以参考下

　　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 .= 'Connection: close'. "rn";

　　$header .= 'Accept: */*'. "rn";

　　$header .= 'User-Agent: '. ( isset($this->args['userAgent']) ? $this->args['userAgent'] : $_SERVER['HTTP_USER_AGENT'] ). "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);

　　}

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

　　$parse = parse_url($url);

　　$host = $parse['host'];

　　$header = 'Host: '. $host. "rn";

　　$header .= 'Connection: close'. "rn";

　　$header .= 'Accept: */*'. "rn";

　　$header .= 'User-Agent: '. ( isset($this->args['userAgent']) ? $this->args['userAgent'] : $_SERVER['HTTP_USER_AGENT'] ). "rn";

　　$header .= 'Content-Type: application/x-www-form-urlencoded'. "rn";

　　$header .= 'DNT: 1'. "rn";

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

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

　　if($data) $header .= 'Content-Length: '. strlen($data). "rn";

　　$options = array();

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

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

　　if($data) $options['http']['content'] = $data;

　　$response = get_headers($url);

　　$this->request = $header;

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

　　$context = stream_context_create($options);

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

　　}

　　}

　　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

　　echo $httpClient->buffer; // 获取 网页内容

　　$httpClient->get('http://www.jb51.net/ServiceLogin/', 'hash='. $time, 'uid=1;users=admin;')

　　echo $httpClient->buffer;
