总结PHP的6种GET和POST远程请求发送方法
1、用file_get_contents 以get方式获取内容:
<?php $url = 'http://www.phprm.com/'; $html = file_get_contents($url); echo $html;
2、用fopen打开url,用get方式获取
$fp = fopen($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方式获取内容: $data = array( 'foo' => 'bar' ); $data = http_build_query($data); $opts = array( 'http' => array( 'method' => 'POST', 'header' => "Content-type: application/x-www-form-urlencoded\r\n" . 'Content-Length: ' . strlen($data) . "\r\n", 'content' => $data ) ); $context = stream_context_create($opts); $html = file_get_contents('http://localhost/e/admin/test.html', false, $context); echo $html;
4、用fsockopen函数打开url,以get方式获取完整的数据,包括header和body, fsockopen需要PHP.ini中allow_url_fopen选项开启
function get_url($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, $request); while (!@feof($fp)) { $result.= @fgets($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 $body; } return false; }
5、用fsockopen函数打开url,以POST方式获取完整的数据,包括header和body
function HTTP_Post($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/1.1\n"; $request.= "Host: " . $URL_Info['host'] . "\n"; $request.= "Referer: $refere\r\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; }
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
$ch = curl_init(); $timeout = 5; curl_setopt($ch, CURLOPT_URL, 'http: //www.phprm.com/'); curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1); curl_setopt($ch, CURLOPT_CONNECTTIMEOUT, $timeout); $file_contents = curl_exec($ch); curl_close($ch); echo $file_contents;
