php實現httpclient類示例

 這篇文章主要介紹了php實現httpclient類示例,需要的朋友可以參考下

 代碼如下: httpClient::init($httpClient, $args = null); $httpClient->get($url, $data = null, $cookie = null); var_dump($httpClient->buffer);      代碼如下: <?php   class httpClient {    public $buffer = null;  // buffer 獲取返回的字符串  public $referer = null;  // referer 設置 HTTP_REFERER 的網址  public $response = null; // response 服務器響應的 header 信息  public $request = null;  // request 發送到服務器的 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; // 獲取 請求頭部信息 echo $httpClient->response; // 獲取 響應的頭部信息 echo $httpClient->buffer; // 獲取 網頁內容   $httpClient->get('http://www.jb51.net/ServiceLogin/', 'hash='. $time, 'uid=1;users=admin;')   echo $httpClient->buffer;
