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. "\r\n";

  $header .= 'Connection: close'. "\r\n";

  $header .= 'Accept: */*'. "\r\n";

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

  $header .= 'DNT: 1'. "\r\n";

  if($cookie) $header .= 'Cookie: '. $cookie. "\r\n";

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

 

  $options = array();

  $options['http']['method'] = 'GET';

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

 

  $response = get_headers($url);

  $this->request = $header;

  $this->response = implode("\r\n", $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. "\r\n";

  $header .= 'Connection: close'. "\r\n";

  $header .= 'Accept: */*'. "\r\n";

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

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

  $header .= 'DNT: 1'. "\r\n";

  if($cookie) $header .= 'Cookie: '. $cookie. "\r\n";

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

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

 

  $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("\r\n", $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;
