如何处理收到的HTTP标头 [英] How to handle received HTTP Header

问题描述

我的问题是如何使用从其他网站收到的php读取标题信息。 （我正在使用patreon webhooks）
文档页面说：

My question is how to read header information with php received from other site. (I'm using patreon webhooks) The documentation page says:

当其中一个事件发生时，我们的服务器将发送HTTP POST到您指定的URL。此HTTP POST将包含来自JSON格式的用户操作的相关数据。它还有标题

X-Patreon-Event： < trigger>

X-Patreon-Signature： < message signature>

其中消息签名是与您的client_secret签署的（与MD5一起）的JSON POST正文HMAC

When one of these events occurs, our servers will send an HTTP POST to a URL you specify. This HTTP POST will contain the relevant data from the user action in JSON format. It will also have headers
X-Patreon-Event: <trigger>
X-Patreon-Signature: <message signature>
where the message signature is the JSON POST body HMAC signed (with MD5) with your client_secret

这是我的代码：

<?php
logData("asd");
$headers = getallheaders();
$X_Patreon_Event = $headers['X-Patreon-Event'];
$X_Patreon_Signature = $headers['X-Patreon-Signature'];
logMusic(json_decode($X_Patreon_Event));
logMusic(json_decode($X_Patreon_Signature));
function logData($str){
    $url = '/var/www/websitelog.txt';
    $current = "$str\n";
    file_put_contents($url,$current,FILE_APPEND | LOCK_EX);
}

推荐答案

getallheaders （自PHP 5.4.0起）将所有标题作为关联数组返回...

getallheaders (since PHP 5.4.0) will return all headers as an associative array...

$headers = getallheaders();

...然后您就可以检查以获取所需的标头值

...that you'll be then able to inspect to fetch the desired headers values

$X_Patreon_Event = $headers['X-Patreon-Event'];
$X_Patreon_Signature = $headers['X-Patreon-Signature'];

附注： getallheaders （）函数可能不可用（例如，如果您的Web服务器是nginx）。在这种情况下，您始终可以使用一小段代码重新实现该功能：从PHP获取当前请求的http标头

---

Side note: getallheaders() function may not be available (for example if your web server is nginx). In that case you can always re-implement the function with a little piece of code: Get the http headers from current request in PHP
