php发送get、post请求的几种方法
From:http://blog.csdn.net/haha00217/article/details/7969504
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 $file_contents;
- ?>
function getRemoteMsg($url) { $ch = curl_init(); curl_setopt($ch, CURLOPT_URL, $url); curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1); curl_setopt($ch, CURLOPT_TIMEOUT, 3); $output = curl_exec($ch); curl_close($ch); return trim($output); }
