先看看浏览器的头信息,谷歌浏览器的头信息大概是这样

火狐的头信息大概是这样的
Host: cs User-Agent: Mozilla/5.0 (Windows NT 10.0; WOW64; rv:49.0) Gecko/20100101 Firefox/49.0 Accept: text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8 Accept-Language: zh-CN,zh;q=0.8,en-US;q=0.5,en;q=0.3 Accept-Encoding: gzip, deflate Cookie: language=zh-HK; hblid=AUtt7xnfu4LKjEQG493Lw1X1GH0VoOAT; olfsk=olfsk4114304963449056; __atuvc=6%7C41%2C0%7C42%2C0%7C43%2C0%7C44%2C1%7C45; currency=USD; PHPSESSID=oljr4n8grvk170m8pfl7r0sen2; default=8cc444c3ab775a1ac3ea5e39fe Connection: keep-alive
一,请求方设置自己的头信息,header.php
<?php
function FormatHeader($url, $myIp = null,$xml = null)
{
// 解析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($result);
?>二,被请求方,取得头信息,header2.php
<?php print_r($_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
curl_setopt($ch, CURLOPT_HEADER, 1); //取得返回头信息
我们把CURLOPT_HEADER设置成1,在取得的结果当中,显示数组的前面会有这些信息
string(1239) "HTTP/1.1 200 OK Date: Fri, 27 May 2011 01:57:57 GMT Server: Apache/2.2.16 (Ubuntu) X-Powered-By: PHP/5.3.3-1ubuntu9.5 Vary: Accept-Encoding Content-Length: 1045 Content-Type: text/html Array ( [HTTP_HOST] => localhost [CONTENT_TYPE] => text/xml; charset=utf-8 [HTTP_ACCEPT] => */*
五,$_SERVER部分头信息是拿不到的
修改一下header.php
<?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
$raw_post_data = file_get_contents('php://input', 'r');
var_dump($raw_post_data);这样就可以取到$xml的内容,并且只会取$xml的内容。
php获取客户端真实ip地址的三种方法
第一种方法
function get_real_ip(){
$ip=false;
if(!empty($_SERVER['HTTP_CLIENT_IP'])){
$ip=$_SERVER['HTTP_CLIENT_IP'];
}
if(!empty($_SERVER['HTTP_X_FORWARDED_FOR'])){
$ips=explode (', ', $_SERVER['HTTP_X_FORWARDED_FOR']);
if($ip){ array_unshift($ips, $ip); $ip=FALSE; }
for ($i=0; $i < count($ips); $i++){
if(!eregi ('^(10│172.16│192.168).', $ips[$i])){
$ip=$ips[$i];
break;
}
}
}
return ($ip ? $ip : $_SERVER['REMOTE_ADDR']);
}第二种方法:
function get_real_ip(){
static $realip;
if(isset($_SERVER)){
if(isset($_SERVER['HTTP_X_FORWARDED_FOR'])){
$realip=$_SERVER['HTTP_X_FORWARDED_FOR'];
}else if(isset($_SERVER['HTTP_CLIENT_IP'])){
$realip=$_SERVER['HTTP_CLIENT_IP'];
}else{
$realip=$_SERVER['REMOTE_ADDR'];
}
}else{
if(getenv('HTTP_X_FORWARDED_FOR')){
$realip=getenv('HTTP_X_FORWARDED_FOR');
}else if(getenv('HTTP_CLIENT_IP')){
$realip=getenv('HTTP_CLIENT_IP');
}else{
$realip=getenv('REMOTE_ADDR');
}
}
return $realip;
}第三种方法,摘自DISCUZ,应该还不错吧!
// 获取IP地址(摘自discuz)
function getIp(){
$ip='未知IP';
if(!empty($_SERVER['HTTP_CLIENT_IP'])){
return is_ip($_SERVER['HTTP_CLIENT_IP'])?$_SERVER['HTTP_CLIENT_IP']:$ip;
}elseif(!empty($_SERVER['HTTP_X_FORWARDED_FOR'])){
return is_ip($_SERVER['HTTP_X_FORWARDED_FOR'])?$_SERVER['HTTP_X_FORWARDED_FOR']:$ip;
}else{
return is_ip($_SERVER['REMOTE_ADDR'])?$_SERVER['REMOTE_ADDR']:$ip;
}
}
function is_ip($str){
$ip=explode('.',$str);
for($i=0;$i<count($ip);$i++){
if($ip[$i]>255){
return false;
}
}
return preg_match('/^[0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}$/',$str);
}php http 协议 发送post请求 中文字符长度怎么算
如我有个post 数据 $date = 'name=adasd&ccc=aaa&bbb=ddd' http协议 发Content-length: 可以先strlen($date);
先将POST数据转化为字符串
以下函数主要原理还是应用递归方式,将多维数组转化为一维数组进行,最后进行数组转字符串处理既可拿到POST过来的数据字符串化;
核心代码:
function getPostLog(array $_data = array(),$n = ''){
if(empty($_data)) return '';
$_gPOST = $_data;
$_rs = array();
foreach ($_gPOST AS $name=>$value){
if( is_array($value) ){
$_rs[] = getPostLog($value,$name);
}else{
if( !empty($_data) ){
$_rs[] = $n.''.$name.''.'='.$value;
}else{
$_rs[] = $name.'='.$value;
}
}
}
$_rs = implode('&', $_rs);
return $_rs;
}然后在URL编码
$strlen = strlen(str_replace(array('%3D','%26'),array('=','&'),urlencode(getPostLog($data))))大功告成
