Question

我需要获取以下请求的位置标头：

当我在chrome中执行它时，

This就是Chrome网络开发工具的请求。

here是Chrome网络开发工具中的重定向请求，以防万一由于某种原因需要它。

我尝试过以下事项：

这似乎只给我一个空洞的答案：

<?php
$url = $_GET["url"];
if (0 === preg_match('/form_build_id" value="form-([^"]*)"/', file_get_contents('http://anything2mp3.com/'), $matches)) exit("false");
$id = $matches[1];

$params = array('http' => array(
    'method' => 'POST',
    'content' => array(
        'url' => $url,
        'op' => "Convert",
        'form_build_id' => "form-" . $id,
        'form_id' => "videoconverter_convert_form"
    ),
    'max_redirects' => "0",
    'header' => "Content-Type:application/x-www-form-urlencoded"
));
stream_context_set_default($params);
$headers = get_headers("http://anything2mp3.com/?q=&mobile_detect_caching_notmobile&mobile_detect_caching_nottablet", false, $ctx);
echo implode("\n", $headers);
?>

我也试过这个：

<?php
$url = $_GET["url"];
if (0 === preg_match('/form_build_id" value="form-([^"]*)"/', file_get_contents('http://anything2mp3.com/'), $matches)) exit("false");
$id = $matches[1];

$params = array('http' => array(
    'method' => 'POST',
    'content' => array(
        'url' => $url,
        'op' => "Convert",
        'form_build_id' => "form-" . $id,
        'form_id' => "videoconverter_convert_form"
    ),
    'max_redirects' => "0",
    'header' => "Content-Type:application/x-www-form-urlencoded"
));
$ctx = stream_context_create($params);
$file = fopen("http://anything2mp3.com/?q=&mobile_detect_caching_notmobile&mobile_detect_caching_nottablet", 'rb', false, $ctx);
$headers = $http_response_header;
echo implode("\n", $headers);
?>

最后一个给出了以下结果：

如您所见，没有位置标题。

请注意我已经看过一些类似的帖子（比如问题6532753，我无法链接它，因为我已经处于我的2链接限制），但它们似乎对我不起作用。

如何从原始屏幕截图中标记的请求中检索位置标头？我错过了什么？

编辑：复制我的代码时我非常努力，对不起

Answer 1

我最终使用像@ frz3993建议的卷曲一样工作（并且在发送一个空白的'cookies'标题后，服务器似乎不喜欢它没有它）

这是我现在使用的代码：

<?php
$url = $_GET["url"];
if (0 === preg_match('/form_build_id" value="form-([^"]*)"/', file_get_contents('http://anything2mp3.com/'), $matches)) exit("false");
$longid = $matches[1];

$ch = curl_init("http://anything2mp3.com/?q=&mobile_detect_caching_notmobile&mobile_detect_caching_nottablet");
curl_setopt($ch, CURLOPT_HEADER, true);
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS, http_build_query(array(
        'url' => $url,
        'op' => "Convert",
        'form_build_id' => "form-" . $longid,
        'form_id' => "videoconverter_convert_form"
    )));
    curl_setopt($ch, CURLOPT_HTTPHEADER, array(
    "Content-Type:application/x-www-form-urlencoded",
    "Cookie:"
    ));
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, false);
$data = curl_exec($ch);
if (0 === preg_match('/Location: (.*id=(\d+))/', $data, $matches)) exit("false");
$redirect = $matches[1];
$id = $matches[2];
echo $redirect;
echo " - ";
echo $longid;
die();
?>

请注意，即使我的OP的第二个建议给了我标题，它也没有给我curl现在做的位置标题。（不要问我为什么：p）

php在发布请求后获取位置标题
