php实现httpRequest的方法_

1、php实现httpRequest的方法_ 这篇文章主要介绍了php实现httpRequest的方法,涉及php操作http的技巧,具有肯定参考借鉴价值,需要的伴侣可以参考下 本文实例讲解并描述了php实现httpRequest的方法。分享给大家供大家参考。具体如下： 想从学校图书馆的网站上抓取数据处理之后在返回给扫瞄器，试了不少方法。首先试了http_request()，但是这个学院pecl_http支持，后来又试了网上流传甚广的class HttpRequest，可能是我不会用法，也失败了。后来看到了函数httpRequest($url, $post=, $method=GET, $limi

2、t=0, $returnHeader=FALSE, $cookie=, $bysocket=FALSE, $ip=, $timeout=15, $block=TRUE)，用它胜利了，因此贴出来分享一下。函数代码如下： 代码如下: ?php /* * Respose A Http Request * * param string $url * param array $post * param string $method * param bool $returnHeader * param string $cookie * param bool $bysocket * param string

3、 $ip * param integer $timeout * param bool $block * return string Response */ function httpRequest($url,$post=,$method=GET,$limit=0,$returnHeader=FALSE,$cookie=,$bysocket=FALSE,$ip=,$timeout=15,$block=TRUE) $return = ; $matches = parse_url($url); !isset($matcheshost) $matcheshost = ; !isset($matches

4、path) $matchespath = ; !isset($matchesquery) $matchesquery = ; !isset($matchesport) $matchesport = ; $host = $matcheshost; $path = $matchespath ? $matchespath.($matchesquery ? ?.$matchesquery : ) : /; $port = !empty($matchesport) ? $matchesport : 80; if(strtolower($method) = post) $post = (is_array(

5、$post) and !empty($post) ? http_build_query($post) : $post; $out = POST $path HTTP/1.0rn; $out .= Accept: */*rn; /$out .= Referer: $boardurlrn; $out .= Accept-Language: zh-cnrn; $out .= Content-Type: application/x-form-urlencodedrn; $out .= User-Agent: $_SERVERHTTP_USER_AGENTrn; $out .= Host: $hostr

6、n; $out .= Content-Length: .strlen($post).rn; $out .= Connection: Closern; $out .= Cache-Control: no-cachern; $out .= Cookie: $cookiernrn; $out .= $post; else $out = GET $path HTTP/1.0rn; $out .= Accept: */*rn; /$out .= Referer: $boardurlrn; $out .= Accept-Language: zh-cnrn; $out .= User-Agent: $_SE

7、RVERHTTP_USER_AGENTrn; $out .= Host: $hostrn; $out .= Connection: Closern; $out .= Cookie: $cookiernrn; $fp = fsockopen($ip ? $ip : $host), $port, $errno, $errstr, $timeout); if(!$fp) return ; else $header = $content = ; stream_set_blocking($fp, $block); stream_set_timeout($fp, $timeout); fwrite($fp

8、, $out); $status = stream_get_meta_data($fp); if(!$statustimed_out) /未超时 while (!feof($fp) $header .= $h = fgets($fp); if($h ($h = rn | $h = n) break; $stop = false; while(!feof($fp) !$stop) $data = fread($fp, ($limit = 0 | $limit 8192 ? 8192 : $limit); $content .= $data; if($limit) $limit -= strlen($data); $stop = $limit = 0; fclose($fp); return $retu
