PHP, curl, and raw headers
提问by Alan Storm
When using the PHP curl functions, is there anyway to see the exact rawheaders that curl is sendingto the server?
使用 PHP curl 函数时，是否可以查看curl发送到服务器的确切原始标头？

You can use curl_getinfo:
您可以使用curl_getinfo：
Before the call
通话前
curl_setopt($ch, CURLINFO_HEADER_OUT, true);
After
后
$headers = curl_getinfo($ch, CURLINFO_HEADER_OUT);

<?php
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, "http://www.example.com/");
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLINFO_HEADER_OUT, true);
curl_exec($ch);
var_dump(curl_getinfo($ch,CURLINFO_HEADER_OUT));
?>
Only available in php 5.1.3 http://php.net/manual/en/function.curl-getinfo.php

You can verify that they are the same by using your console and hitting
您可以通过使用控制台并点击来验证它们是否相同
curl http://example.com/-I
curl http://example.com/-I
or
或者
curl --trace-ascii /file.txt http://example.com/
curl --trace-ascii /file.txt http://example.com/

AFAIK, the PHP/CURL binding still lacks proper support for CURLOPT_DEBUGFUNCTION which is a callback from libcurl that can provide all those details.
AFAIK，PHP/CURL 绑定仍然缺乏对 CURLOPT_DEBUGFUNCTION 的适当支持，这是来自 libcurl 的回调，可以提供所有这些细节。
That's the primary reason why I recommend people to work out HTTP scripting things with the curl command line tool and its --trace-ascii option FIRST, then translate that into a PHP function.
这就是我建议人们首先使用 curl 命令行工具及其 --trace-ascii 选项来编写 HTTP 脚本的主要原因，然后将其转换为 PHP 函数。

be sure to set the CURLINFO_HEADER_OUT option before making the curl_getinfo call
确保在调用 curl_getinfo 之前设置 CURLINFO_HEADER_OUT 选项
curl_setopt($c, CURLINFO_HEADER_OUT, true);
curl_setopt($c, CURLINFO_HEADER_OUT, true);
