php发送get、post请求获取内容的几种方法

方法1: 用file_get_contents 以get方式获取内容  <?php$url=‘http://www.domain.com/‘;$html = file_get_contents($url);echo $html;?>方法2: 用fopen打开url, 以get方式获取内容    <?php  $fp = fopen($url, ‘r‘);  //返回请求流信息(数组:请求状态,阻塞,返回值是否为空,返回值http头等)stream_get_meta_data($fp);  while(!feof($fp)) {  $result .= fgets($fp, 1024);  }  echo "url body: $result";  fclose($fp);  ?>方法3:用file_get_contents函数,以post方式获取url    <?php  $data = array (‘foo‘ => ‘bar‘);//生成url-encode后的请求字符串,将数组转换为字符串  $data = http_build_query($data);  $opts = array (  <span style="white-space:pre">  </span>‘http‘ => array (  <span style="white-space:pre">      </span>‘method‘ => ‘POST‘,  <span style="white-space:pre">      </span>‘header‘=> "Content-type: application/x-www-form-urlencoded\r\n" .  <span style="white-space:pre">      </span>"Content-Length: " . strlen($data) . "\r\n",  <span style="white-space:pre">      </span>‘content‘ => $data  <span style="white-space:pre">  </span>)  );//生成请求的句柄文件  $context = stream_context_create($opts);  $html = file_get_contents(‘http://localhost/e/admin/test.html‘, false, $context);  echo $html;  ?>方法4:用fsockopen函数打开url,以get方式获取完整的数据,包括header和body,fsockopen需要 PHP.ini 中 allow_url_fopen 选项开启        <?php      function get_url ($url,$cookie=false)      {      $url = parse_url($url);      $query = $url[path]."?".$url[query];      echo "Query:".$query;      $fp = fsockopen( $url[host], $url[port]?$url[port]:80 , $errno, $errstr, 30);      if (!$fp) {      return false;      } else {      $request = "GET $query HTTP/1.1\r\n";      $request .= "Host: $url[host]\r\n";      $request .= "Connection: Close\r\n";      if($cookie) $request.="Cookie:   $cookie\n";      $request.="\r\n";      fwrite($fp,$request);      while()) {      $result .= @fgets($fp, 1024);      }      fclose($fp);      return $result;      }      }      //获取url的html部分,去掉header      function GetUrlHTML($url,$cookie=false)      {      $rowdata = get_url($url,$cookie);      if($rowdata)      {      $body= stristr($rowdata,"\r\n\r\n");      $body=substr($body,4,strlen($body));      return $body;      }          return false;      }      ?>方法5:用fsockopen函数打开url,以POST方式获取完整的数据,包括header和body        <?php      function HTTP_Post($URL,$data,$cookie, $referrer="")      {          // parsing the given URL      $URL_Info=parse_url($URL);          // Building referrer      if($referrer=="") // if not given use this script as referrer      $referrer="111";          // making string from $data      foreach($data as $key=>$value)      $values[]="$key=".urlencode($value);      $data_string=implode("&",$values);          // Find out which port is needed - if not given use standard (=80)      if(!isset($URL_Info["port"]))      $URL_Info["port"]=80;          // building POST-request:      $request.="POST ".$URL_Info["path"]." HTTP/1.1\n";      $request.="Host: ".$URL_Info["host"]."\n";      $request.="Referer: $referer\n";      $request.="Content-type: application/x-www-form-urlencoded\n";      $request.="Content-length: ".strlen($data_string)."\n";      $request.="Connection: close\n";          $request.="Cookie:   $cookie\n";          $request.="\n";      $request.=$data_string."\n";          $fp = fsockopen($URL_Info["host"],$URL_Info["port"]);      fputs($fp, $request);      while(!feof($fp)) {      $result .= fgets($fp, 1024);      }      fclose($fp);          return $result;      }      ?>方法6:使用curl库,使用curl库之前,可能需要查看一下php.ini是否已经打开了curl扩展  <?php  $ch = curl_init();  $timeout = 5;  curl_setopt ($ch, CURLOPT_URL, ‘http://www.domain.com/‘);  curl_setopt ($ch, CURLOPT_RETURNTRANSFER, 1);  curl_setopt ($ch, CURLOPT_CONNECTTIMEOUT, $timeout);  $file_contents = curl_exec($ch);  curl_close($ch);  echo $file_contents;  ?>
