    PHP的GET和POST請求發送方法

      在i94web博客中,我試過了暢言和多說兩種社會化評論框,后來還是拋棄了暢言,不安全。無論是暢言還是多說,我都需要從遠程抓取文章的評論數,然后存入本地數據庫。對于多說,請求的格式如下,就跟隨小編去了解下吧,想了解更多相關信息請 持續關注我們應屆畢業生考試網!

      // 獲取評論次數,參數是文章ID

      function getCommCount($postid)

      {

      $jsondata = file_get_contents("http://api.duoshuo.com/threads/counts.json?short_name=i94web&threads=$postid"); // 設置true返回數組,不設置或者是false則返回對象 $resjson= json_decode($jsondata,true); return $resjson['response'][$postid]['comments'];

      }

      對于遠程請求,有很多種方法。今天,LZ就搜羅了六種,供大家參考。

      1、用file_get_contents 以get方式獲取內容:

      <?php

      $url='http://www.ido321.com/';

      $html = file_get_contents($url);

      echo $html;

      ?>

      2、用fopen打開url,用get方式獲取

      $fp = fopen($url, 'r');

      stream_get_meta_data($fp);

      while(!feof($fp)) {

      $result .= fgets($fp, 1024);

      }

      echo "url body: $result";

      fclose($fp);

      3、用file_get_contents 以post方式獲取內容:

      $data = array ('foo' => 'bar');

      $data = http_build_query($data);

      $opts = array (

      'http' => array (

      'method' => 'POST',

      'header'=> "Content-type: application/x-www-form-urlencodedrn" . 'Content-Length: ' . strlen($data) . 'rn', 'content' => $data ) ); $context = stream_context_create($opts); $html = file_get_contents('http://localhost/e/admin/test.html', false, $context); echo $html;

      4、用fsockopen函數打開url,以get方式獲取完整的數據,包括header和body,fsockopen需要 PHP.ini 中 allow_url_fopen 選項開啟

      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/1.1rn';

      $request .= 'Host: $url[host]rn';

      $request .= 'Connection: Closern';

      if($cookie) $request.='Cookie:  $cookien';

      $request.='rn';

      fwrite($fp,$request);

      while(!@feof($fp)) {

      $result .= @fgets($fp, 1024);

      }

      fclose($fp);

      return $result;

      }

      }

      //獲取url的html部分,去掉header

      function GetUrlHTML($url,$cookie=false)

      {

      $rowdata = get_url($url,$cookie);

      if($rowdata)

      {

      $body= stristr($rowdata,'rnrn');

      $body=substr($body,4,strlen($body));

      return $body;

      }

      return false;

      }

      5、用fsockopen函數打開url,以POST方式獲取完整的數據,包括header和body

      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/1.1n"; $request.="Host: ".$URL_Info['host']."n"; $request.="Referer: $referern"; $request.="Content-type: application/x-www-form-urlencodedn"; $request.='Content-length: '.strlen($data_string)."n"; $request.='Connection: closen'; $request.='Cookie: $cookien'; $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;

      }

      6、使用curl庫,使用curl庫之前,可能需要查看一下php.ini是否已經打開了curl擴展

      $ch = curl_init();

      $timeout = 5;

      curl_setopt ($ch, CURLOPT_URL, ‘http://www.ido321.com/');

      curl_setopt ($ch, CURLOPT_RETURNTRANSFER, 1);

      curl_setopt ($ch, CURLOPT_CONNECTTIMEOUT, $timeout);

      $file_contents = curl_exec($ch);

      curl_close($ch);

      echo $file_contents;
