Question

我试图使用fsockopen发布数据，然后返回结果。这是我目前的代码：

<?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日星期二格林尼治标准时间22:40:46：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）“”Array（）

我有什么不对？为什么变量不发布其数据？

Answer 1

您的代码中存在许多小错误。这是一个经过测试和运作的片段。

<?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上放这个

<?php print_r($_POST);

运行时，您应该获得类似

的输出

HTTP/1.1 200 OK

Connection: close

1f
Array
(
    [hello] => world
)

绝不会将$data写入套接字。你想要添加如下内容：

$out .= "Connection: Close\r\n\r\n";
fwrite($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);
}
?>

某些字符转义符如\n不适用于单引号。

很好的Tamlyn，效果很好！

对于那些还需要发送获取变量和网址的人，

//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$_POST[]变量中，而是在$GLOBALS['HTTP_RAW_POST_DATA']变量中。

你可以使用这种技术，它可以帮助调用你喜欢的页面，所有页面将一次独立运行，而不必等待每个页面响应异步。

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);
            }
            ?>

<强> testpage.php

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

Answer 8

在某些情况下，使用post_to_host（）：

，卷曲太重了

//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');

使用cURL和选项？

Answer 10

很抱歉刷新，但对于仍有这样问题的人，请将HTTP / 1.0更改为HTTP / 1.1，它会起作用。
