PHP 使用 Fsockopen 发布数据

Question

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);
}
?> 

它应该回显页面，并且它正在回显页面，但这是 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 );  
?>

结果是：

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 内容长度：31 连接：关闭 内容类型：text/html；字符集=UTF-8 string(0) "" 数组 ( )

我有什么问题吗？为什么变量不发布其数据？

Answer 1

您的代码中有很多小错误。这是一个经过测试并且有效的代码片段。

<?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);
}

然后在 example.com/reposter.php 把这个

<?php print_r($_POST);

当运行时你应该得到类似的输出

HTTP/1.1 200 OK
Date: Wed, 05 Jan 2011 21:24:07 GMT
Server: Apache
X-Powered-By: PHP/5.2.9
Vary: Host
Content-Type: text/html
Connection: close

1f
Array
(
    [hello] => world
)
0

Answer 2

$data 绝不会被写入套接字。你想添加类似的内容：

$out .= "Connection: Close\r\n\r\n";
fwrite($fp, $out);
fwrite($fp, $data);

Answer 3

试试这个

$out .= 'Content-Length: ' . strlen($data) . '\r\n';
$out .= "Connection: Close\r\n\r\n";
$out .= $data;

Answer 4

试试这个：

<?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, $out);
    fwrite($fp, $data);
    while (!feof($fp)) {
        echo fgets($fp, 128);
    }
    fclose($fp);
}
?> 

某些字符转义符（例如 \n）在单引号中不起作用。

Answer 5

Tamlyn 不错，效果很好！

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");

Answer 6

在 reposter.php 中尝试这个

$raw_data = $GLOBALS['HTTP_RAW_POST_DATA']; 
parse_str( $raw_data, $_POST );

print_r( $_POST );

，因为数据不在 $_POST[] 变量中，而是在 $GLOBALS['HTTP_RAW_POST_DATA'] 变量中。

您可以使用此技术，它将有助于调用任意数量的页面，所有页面将立即独立运行，而无需异步等待每个页面响应。

cornjobpage.php //mainpage

    <?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

    <?
    echo $_REQUEST["Keywordname"];//case1 Output > testValue
    ?>

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');

是否使用 cURL 和选项？

Answer 10

抱歉刷新，但是对于仍然遇到此类问题的人，将 HTTP/1.0 更改为 HTTP/1.1 即可。
