使用PHP获取原始请求 [英] Get the raw request using PHP
问题描述
我正在寻找一种方法来使用本机PHP获取我的脚本收到的原始HTTP请求,包括标题和正文。阅读PHP文档我无法找到获取原始请求的标准方法,无论使用何种HTTP方法。
I'm looking for a way to get, using native PHP, the raw HTTP request that my script received, including headers and body. Reading the PHP documentation I cant found a standard way to get the raw request, regardless the HTTP method used.
例如,当请求页面test.php时,我想得到完整的请求,如:
For example, when the page test.php is requested, I want to get the complete request like:
GET /test.php HTTP/1.1
Host:....
....
....
同样的情况POST,HEAD等......
The same in case of POST, HEAD, etc...
似乎很奇怪,没有一种方法可以访问原始请求缓冲区!
Seems very strange that there doesn't exist a method to access the raw request buffer!
推荐答案
查看手册似乎没有未经过原始访问的请求以匹配您想要的内容,因此我怀疑您需要重新构建您想从 $ _ SERVER
变量中得到什么。快速搜索我发现这个类,做了一些小改动来获得 GET / HTTP / 1.1
,也许你会发现它适合你的需要。
Looking over the manual there doesn't seem to be an unparsed raw access to the request to match what you want, so I suspect you will need to re-build what you want from the $_SERVER
variables. A quick search I found this class, made some small change to get the GET / HTTP/1.1
, perhaps you will find it suits your needs.
