PHP Post data with Fsockopen
提问by Joseph Robidoux
I am attempting to post data using fsockopen, and then returning the result. Here is my current code:
我正在尝试使用 fsockopen 发布数据，然后返回结果。这是我当前的代码：
<?php
$data="stuff=hoorah\r\n";
$data=urlencode($data);
$fp = fsockopen("www.website.com", 80, $errno, $errstr, 30);
if (!$fp) {
echo "$errstr ($errno)<br />\n";
} else {
$out = "POST /script.php HTTP/1.0\r\n";
$out .= "Host: www.webste.com\r\n";
$out .= 'Content-Type: application/x-www-form-urlencoded\r\n';
$out .= 'Content-Length: ' . strlen($data) . '\r\n\r\n';
$out .= "Connection: Close\r\n\r\n";
fwrite($fp, $out);
while (!feof($fp)) {
echo fgets($fp, 128);
}
fclose($fp);
}
?>
It is supposed to echo the page, and it is echoing the page, but here is the script for script.php
它应该回显页面，它正在回显页面，但这里是 script.php 的脚本
<?php
echo "<br><br>";
$raw_data = $GLOBALS['HTTP_RAW_POST_DATA'];
parse_str( $raw_data, $_POST );
//test 1
var_dump($raw_data);
echo "<br><br>":
//test 2
print_r( $_POST );
?>
The outcome is:
结果是：
HTTP/1.1 200 OK Date: Tue, 02 Mar 2010 22:40:46 GMT Server: Apache/2.2.3 (CentOS) X-Powered-By: PHP/5.2.6 Content-Length: 31 Connection: close Content-Type: text/html; charset=UTF-8 string(0) "" Array ( )
HTTP/1.1 200 OK 日期：2010 年 3 月 2 日星期二 22:40:46 GMT 服务器：Apache/2.2.3 (CentOS) X-Powered-By：PHP/5.2.6 Content-Length：31 连接：close Content-Type ：文本/html；charset=UTF-8 string(0) "" 数组 ( )
What do I have wrong? Why isn't the variable posting its data?
我有什么问题？为什么变量不发布其数据？

There are many small errors in your code. Here's a snippet which is tested and works.
您的代码中有许多小错误。这是一个经过测试并有效的片段。
<?php
$fp = fsockopen('example.com', 80);
$vars = array(
'hello' => 'world'
);
$content = http_build_query($vars);
fwrite($fp, "POST /reposter.php HTTP/1.1\r\n");
fwrite($fp, "Host: example.com\r\n");
fwrite($fp, "Content-Type: application/x-www-form-urlencoded\r\n");
fwrite($fp, "Content-Length: ".strlen($content)."\r\n");
fwrite($fp, "Connection: close\r\n");
fwrite($fp, "\r\n");
fwrite($fp, $content);
header('Content-type: text/plain');
while (!feof($fp)) {
echo fgets($fp, 1024);
}
And then at example.com/reposter.php put this
然后在example.com/reposter.php把这个
<?php print_r($_POST);
When run you should get output something like
运行时你应该得到类似的输出

At no point is $databeing written to the socket. You want to add something like:
任何时候都$data没有写入套接字。您想添加如下内容：
$out .= "Connection: Close\r\n\r\n";
fwrite($fp, $out);
fwrite($fp, $data);
回答by Ben Rowe
Try this instead
试试这个
$out .= 'Content-Length: ' . strlen($data) . '\r\n';
$out .= "Connection: Close\r\n\r\n";
$out .= $data;

Some character escapes such as \ndo not work in single quotes.
某些字符转义，例如\n在单引号中不起作用。

you can use this technique it will help to call as many as pages you like all pages will run at once independently without waiting for each page response as asynchronous.
您可以使用此技术，它有助于调用尽可能多的页面，所有页面将独立运行，而无需等待每个页面响应为异步。
cornjobpage.php //mainpage
cornjobpage.php //主页
<?php
post_async("http://localhost/projectname/testpage.php", "Keywordname=testValue");
//post_async("http://localhost/projectname/testpage.php", "Keywordname=testValue2");
//post_async("http://localhost/projectname/otherpage.php", "Keywordname=anyValue");
//call as many as pages you like all pages will run at once independently without waiting for each page response as asynchronous.
?>
<?php
/*
* Executes a PHP page asynchronously so the current page does not have to wait for it to finish running.
*
*/
function post_async($url,$params)
{
$post_string = $params;
$parts=parse_url($url);
$fp = fsockopen($parts['host'],
isset($parts['port'])?$parts['port']:80,
$errno, $errstr, 30);
$out = "POST ".$parts['path']."?$post_string"." HTTP/1.1\r\n";//you can use GET instead of POST if you like
$out.= "Host: ".$parts['host']."\r\n";
$out.= "Content-Type: application/x-www-form-urlencoded\r\n";
$out.= "Content-Length: ".strlen($post_string)."\r\n";
$out.= "Connection: Close\r\n\r\n";
fwrite($fp, $out);
fclose($fp);
}
?>
testpage.php
测试页
<?
echo $_REQUEST["Keywordname"];//case1 Output > testValue
?>

Nice one Tamlyn, works great!
不错的一个 Tamlyn，效果很好！
For those that also need to send get vars along with the url,
对于那些还需要随 url 一起发送 get vars 的人，
//change this:
fwrite($fp, "POST /reposter.php HTTP/1.1\r\n");
//to:
$query = 'a=1&b=2';
fwrite($fp, "POST /reposter.php?".$query." HTTP/1.1\r\n");
回答by chandoo
Try this in reposter.php
在reposter.php 中试试这个
$raw_data = $GLOBALS['HTTP_RAW_POST_DATA'];
parse_str( $raw_data, $_POST );
print_r( $_POST );
Because, the data wasn't in the $_POST[]variables but it was in the $GLOBALS['HTTP_RAW_POST_DATA']variable.
因为，数据不在$_POST[]变量中，而是在$GLOBALS['HTTP_RAW_POST_DATA']变量中。

Curl is too heavy in some case, to use post_to_host():
在某些情况下，Curl 太重，无法使用 post_to_host()：
//GET:
$str_rtn=post_to_host($str_url_target, array(), $arr_cookie, $str_url_referer, $ref_arr_head, 0);
//POST:
$arr_params=array('para1'=>'...', 'para2'=>'...');
$str_rtn=post_to_host($str_url_target, $arr_params, $arr_cookie, $str_url_referer, $ref_arr_head);
//POST with file:
$arr_params=array('para1'=>'...', 'FILE:para2'=>'/tmp/test.jpg', 'para3'=>'...');
$str_rtn=post_to_host($str_url_target, $arr_params, $arr_cookie, $str_url_referer, $ref_arr_head, 2);
//raw POST:
$tmp=array_search('uri', @array_flip(stream_get_meta_data($GLOBALS[mt_rand()]=tmpfile())));
$arr_params=array('para1'=>'...', 'para2'=>'...');
file_put_contents($tmp, json_encode($arr_params));
$arr_params=array($tmp);
$str_rtn=post_to_host($str_url_target, $arr_params, $arr_cookie, $str_url_referer, $ref_arr_head, 3);
//get cookie and merge cookies:
$arr_new_cookie=get_cookies_from_heads($ref_arr_head)+$arr_old_cookie;//don't change the order
//get redirect url:
$str_url_redirect=get_from_heads($ref_arr_head, 'Location');
post to host php project location: http://code.google.com/p/post-to-host/
发布到托管 php 项目位置：http: //code.google.com/p/post-to-host/

Sorry for refresh, but for people who still have problem like this, change HTTP/1.0 to HTTP/1.1 and it will work.
抱歉刷新，但对于仍然有这样问题的人，将 HTTP/1.0 更改为 HTTP/1.1 它将起作用。
