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,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 );  
?>

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 Content-Length: 31 Connection: close Content-Type :文本/html;charset=UTF-8 字符串(0) "" 数组 ( )

我有什么问题?为什么变量不发布其数据?

您的代码中有许多小错误。这是一个经过测试和工作的片段。

<?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);
}

然后在 example.com/reposter.php 把这个

<?php print_r($_POST);

运行时,您应该得到类似的输出

HTTP/1.1 200 OK

绝不$data会写入套接字。你想添加类似的东西:

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

尝试这个:

<?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,例如\n在单引号中不起作用。

试试这个

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

在reposter.php中试试这个

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

print_r( $_POST );

因为,数据不在$_POST[]变量中,但在$GLOBALS['HTTP_RAW_POST_DATA']变量中。

不错的 Tamlyn,效果很好!

对于那些还需要与 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");

您可以使用这种技术,它将帮助您调用任意数量的页面,所有页面将同时独立运行,而无需等待每个页面响应为异步的。

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);
            }
            ?>

测试页.php

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

在某些情况下,卷曲太重,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');

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。
