php中如何设置头信息,如何取得返回头信息?设置请求的头信息,我们可以用header函数,可以用fsockopen,可以用curl等,本文主要讲的是用curl来设置头信息,并取得返回后的头信息。
一,请求方设置自己的头信息,header.php
查看复制打印? 1.<?php 2.function FormatHeader($url, $myIp = null,$xml = null) 3.{ 4. // 解悉url 5. $temp = parse_url($url); 6. $query = isset($temp['query']) ? $temp['query'] : ''; 7. $path = isset($temp['path']) ? $temp['path'] : '/'; 8. 9. $header = array ( 10. "POST {$path}?{$query} HTTP/1.1", 11. "Host: {$temp['host']}", 12. "Content-Type: text/xml; charset=utf-8", 13. 'Accept: */*', 14. "Referer: http://{$temp['host']}/", 15. 'User-Agent: Mozilla/4.0 (compatible; MSIE 7.0; Windows NT 5.1; SV1)', 16. "X-Forwarded-For: {$myIp}", 17. "Content-length: 380", 18. "Connection: Close" 19. ); 20. 21. return $header; 22.} 23. 24.$interface = 'http://localhost/test/header2.php'; 25.$header = FormatHeader($interface,'10.1.11.1'); 26. 27.$ch = curl_init(); 28.curl_setopt($ch, CURLOPT_URL, $interface); 29.curl_setopt($ch, CURLOPT_HTTPHEADER, $header); //设置头信息的地方 30.curl_setopt($ch, CURLOPT_HEADER, 0); //不取得返回头信息 31.curl_setopt($ch, CURLOPT_TIMEOUT, 5); 32.curl_setopt($ch, CURLOPT_RETURNTRANSFER, true); 33.$result = curl_exec($ch); 34. 35.var_dump($result); 36.?> <?php function FormatHeader($url, $myIp = null,$xml = null) { // 解悉url $temp = parse_url($url); $query = isset($temp['query']) ? $temp['query'] : ''; $path = isset($temp['path']) ? $temp['path'] : '/';
$header = array ( "POST {$path}?{$query} HTTP/1.1", "Host: {$temp['host']}", "Content-Type: text/xml; charset=utf-8", 'Accept: */*', "Referer: http://{$temp['host']}/", 'User-Agent: Mozilla/4.0 (compatible; MSIE 7.0; Windows NT 5.1; SV1)', "X-Forwarded-For: {$myIp}", "Content-length: 380", "Connection: Close" );
return $header; }
$interface = 'http://localhost/test/header2.php'; $header = FormatHeader($interface,'10.1.11.1');
$ch = curl_init(); curl_setopt($ch, CURLOPT_URL, $interface); curl_setopt($ch, CURLOPT_HTTPHEADER, $header); //设置头信息的地方 curl_setopt($ch, CURLOPT_HEADER, 0); //不取得返回头信息 curl_setopt($ch, CURLOPT_TIMEOUT, 5); curl_setopt($ch, CURLOPT_RETURNTRANSFER, true); $result = curl_exec($ch);
var_dump($result); ?>二,被请求方,取得头信息,header2.php
查看复制打印? 1.<?php 2.print_r($_SERVER); //头信息里面有内容绝大部分是放在系统变量里面的 3.?> <?php print_r($_SERVER); //头信息里面有内容绝大部分是放在系统变量里面的 ?>三,看一下header.php请求的结果
string(1045) "Array ( [HTTP_HOST] => localhost [CONTENT_TYPE] => text/xml; charset=utf-8 [HTTP_ACCEPT] => */* [HTTP_REFERER] => http://localhost/ [HTTP_USER_AGENT] => Mozilla/4.0 (compatible; MSIE 7.0; Windows NT 5.1; SV1) [HTTP_X_FORWARDED_FOR] => 10.1.11.1 [CONTENT_LENGTH] => 380 [PATH] => /usr/local/bin:/usr/bin:/bin [SERVER_SIGNATURE] => <address>Apache/2.2.16 (Ubuntu) Server at localhost Port 80</address> 。。。。。。。。。。。。。。。。。。。。。。。。。。。。 )
上面那几个,我们可以明显看到,是我设置的头信息。
四,取得返回的头信息
查看复制打印? 1.curl_setopt($ch, CURLOPT_HEADER, 1); //取得返回头信息 curl_setopt($ch, CURLOPT_HEADER, 1); //取得返回头信息我们把CURLOPT_HEADER设置成1,在取得的结果当中,显示数组的前面会有这些信息
查看复制打印? 1.string(1239) "HTTP/1.1 200 OK 2.Date: Fri, 27 May 2011 01:57:57 GMT 3.Server: Apache/2.2.16 (Ubuntu) 4.X-Powered-By: PHP/5.3.3-1ubuntu9.5 5.Vary: Accept-Encoding 6.Content-Length: 1045 7.Content-Type: text/html 8. 9.Array 10.( 11. [HTTP_HOST] => localhost 12. [CONTENT_TYPE] => text/xml; charset=utf-8 13. [HTTP_ACCEPT] => */* 14. 。。。。。。。。。。。。。。。。 string(1239) "HTTP/1.1 200 OK Date: Fri, 27 May 2011 01:57:57 GMT Server: Apache/2.2.16 (Ubuntu) X-Powered-By: PHP/5.3.3-1ubuntu9.5 Vary: Accept-Encoding Content-Length: 1045 Content-Type: text/html
Array ( [HTTP_HOST] => localhost [CONTENT_TYPE] => text/xml; charset=utf-8 [HTTP_ACCEPT] => */* 。。。。。。。。。。。。。。。。五,$_SERVER部分头信息是拿不到的
修改一下header.php
查看复制打印? 1.<?php 2.function FormatHeader($url, $myIp = null,$xml = null) 3.{ 4. // 解悉url 5. $temp = parse_url($url); 6. $query = isset($temp['query']) ? $temp['query'] : ''; 7. $path = isset($temp['path']) ? $temp['path'] : '/'; 8. 9. $header = array ( 10. "POST {$path}?{$query} HTTP/1.1", 11. "Host: {$temp['host']}", 12. "Content-Type: text/xml; charset=utf-8", 13. 'Accept: */*', 14. "Referer: http://{$temp['host']}/", 15. 'User-Agent: Mozilla/4.0 (compatible; MSIE 7.0; Windows NT 5.1; SV1)', 16. "X-Forwarded-For: {$myIp}", 17. "Content-length: " . strlen($xml) ."\r\n\r\n" .$xml, //修改1 18. "Connection: Close" 19. ); 20. 21. return $header; 22.} 23. 24.$xml = '<?xml version="1.0" encoding="utf-8"?> //修改2 25. <profile> 26. <sha1>adsfadsf</sha1> 27. <user_id>asdfasdf</user_id> 28. <album_id>asdf</album_id> 29. <album_name>asdf</album_name> 30. <tags>asdfasd</tags> 31. <title>asdfasdf</title> 32. <content>asdfadsf</content> 33. <type>asdfasdf</type> 34. <copyright>asdfasdf</copyright> 35. </profile>'; 36. 37.$interface = 'http://localhost/test/header2.php'; 38.$header = FormatHeader($interface,'10.1.11.1',$xml); //修改3 39. 40.$ch = curl_init(); 41.curl_setopt($ch, CURLOPT_URL, $interface); 42.curl_setopt($ch, CURLOPT_HTTPHEADER, $header); //设置头信息的地方 43.curl_setopt($ch, CURLOPT_HEADER, 0); //不取得返回头信息 44.curl_setopt($ch, CURLOPT_TIMEOUT, 5); 45.curl_setopt($ch, CURLOPT_RETURNTRANSFER, true); 46.$result = curl_exec($ch); 47. 48.var_dump($result); 49.?> <?php function FormatHeader($url, $myIp = null,$xml = null) { // 解悉url $temp = parse_url($url); $query = isset($temp['query']) ? $temp['query'] : ''; $path = isset($temp['path']) ? $temp['path'] : '/';
$header = array ( "POST {$path}?{$query} HTTP/1.1", "Host: {$temp['host']}", "Content-Type: text/xml; charset=utf-8", 'Accept: */*', "Referer: http://{$temp['host']}/", 'User-Agent: Mozilla/4.0 (compatible; MSIE 7.0; Windows NT 5.1; SV1)', "X-Forwarded-For: {$myIp}", "Content-length: " . strlen($xml) ."\r\n\r\n" .$xml, //修改1 "Connection: Close" );
return $header; }
$xml = '<?xml version="1.0" encoding="utf-8"?> //修改2 <profile> <sha1>adsfadsf</sha1> <user_id>asdfasdf</user_id> <album_id>asdf</album_id> <album_name>asdf</album_name> <tags>asdfasd</tags> <title>asdfasdf</title> <content>asdfadsf</content> <type>asdfasdf</type> <copyright>asdfasdf</copyright> </profile>';
$interface = 'http://localhost/test/header2.php'; $header = FormatHeader($interface,'10.1.11.1',$xml); //修改3
$ch = curl_init(); curl_setopt($ch, CURLOPT_URL, $interface); curl_setopt($ch, CURLOPT_HTTPHEADER, $header); //设置头信息的地方 curl_setopt($ch, CURLOPT_HEADER, 0); //不取得返回头信息 curl_setopt($ch, CURLOPT_TIMEOUT, 5); curl_setopt($ch, CURLOPT_RETURNTRANSFER, true); $result = curl_exec($ch);
var_dump($result); ?>如果这样的话,header2.php里面,打印$_SERVER不可能把头信息中的xml打印出来。这个时候,我们在header2.php后面加上以下二行
查看复制打印? 1.$raw_post_data = file_get_contents('php://input', 'r'); 2.var_dump($raw_post_data); $raw_post_data = file_get_contents('php://input', 'r'); var_dump($raw_post_data);这样就可以取到$xml的内容,并且只会取$xml的内容。
