本文实例讲述了php实现httpRequest的方法。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浏览器,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html' target='_blank'>class HttpRequest,可能是我不会使用,也失败了。后来看到了函数httpRequest($url, $post= , $method= GET , $limit=0, $returnHeader=FALSE, $cookie= , $bysocket=FALSE, $ip= , $timeout=15, $block=TRUE),用它成功了,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 $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($matches[ host ]) $matches[ host ] = !isset($matches[ path ]) $matches[ path ] = !isset($matches[ query ]) $matches[ query ] = !isset($matches[ port ]) $matches[ port ] = $host = $matches[ host $path = $matches[ path ] ? $matches[ path ].($matches[ query ] ? ? .$matches[ query ] : ) : / $port = !empty($matches[ port ]) ? $matches[ port ] : 80; if(strtolower($method) == post ) { $post = (is_array($post) and !empty($post)) ? http_build_query($post) : $post; $out = POST $path HTTP/1.0/r/n $out .= Accept: */*/r/n //$out .= Referer: $boardurl/r/n $out .= Accept-Language: zh-cn/r/n $out .= Content-Type: application/x-www-form-urlencoded/r/n $out .= User-Agent: $_SERVER[HTTP_USER_AGENT]/r/n $out .= Host: $host/r/n $out .= Content-Length: .strlen($post). /r/n $out .= Connection: Close/r/n $out .= Cache-Control: no-cache/r/n $out .= Cookie: $cookie/r/n/r/n $out .= $post; } else { $out = GET $path HTTP/1.0/r/n $out .= Accept: */*/r/n //$out .= Referer: $boardurl/r/n $out .= Accept-Language: zh-cn/r/n $out .= User-Agent: $_SERVER[HTTP_USER_AGENT]/r/n $out .= Host: $host/r/n $out .= Connection: Close/r/n $out .= Cookie: $cookie/r/n/r/n $fp = fsockopen(($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, $out); $status = stream_get_meta_data($fp); if(!$status[ timed_out ]) {//未超时 while (!feof($fp)) { $header .= $h = fgets($fp); if($h ($h == /r/n || $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 = $limit fclose($fp); return $returnHeader ? array($header,$content) : $content; ?
调用也很简单的。简单的例子:
代码如下:
echo httpRequest( http://www.baidu.com
