mod_rewrite：如何重定向HTTP DELETE和PUT [英] mod_rewrite: How to redirect HTTP DELETE and PUT

问题描述

我试图通过使用mod_rewrite在php中编写一个小的rest api。

Im trying to write a little rest api in php by using mod_rewrite.

我的问题是：
如何处理HTTP DELETE和PUT？
例如，网址为：
/ book / 1234

My question is: How do I handle HTTP DELETE and PUT? For example, the url would be: /book/1234

其中1234是图书的唯一ID。我想将这个id（1234）重定向到book.php，id为参数。我已经知道如何在php脚本中读取PUT和DELETE变量，但是如何在mod_rewrite中设置这个重写规则？

where 1234 is the unique id of a book. I want to "redirect" this id (1234) to book.php with the id as parameter. I already know how to read PUT and DELETE variables in the php script, but how do I set this rewrite rules in mod_rewrite?

任何想法？

编辑：
GET的重写规则如下所示：

The rewriting rule for a GET would look like this:

RewriteRule book/([0-9]+) book.php?id=$1 [QSA] 

如何为PUT和DELETE执行参数转发？据我所知HTTP POST，PUT和DELETE使用HTTP Request Body来传输参数值。所以我想我需要在HTTP请求体中附加参数。但我不知道如何用mod_rewrite做到这一点。

How do I do this "parameter forwarding" for PUT and DELETE? As far as I know HTTP POST, PUT and DELETE use the HTTP Request Body for transmitting parameter values. So I guess I need to append the parameter in the HTTP request body. But I have no idea how to do that with mod_rewrite.

我可以做一些混合DELETE和GET吗？

Can I do some kind of mixing DELETE and GET?

RewriteCond %{REQUEST_METHOD} =DELETE
RewriteRule book/([0-9]+) book.php?id=$1 [QSA] 

然后在book.php中，我会使用$ _GET ['id']来检索图书ID，即使HTTP HEADER说HTTP METHOD是DELETE。它似乎不起作用...

Then in book.php I would user $_GET['id'] to retrieve the book id, even if the HTTP HEADER says that the HTTP METHOD is DELETE. It does not seems to work ...

推荐答案

我可以做某种混合DELETE和GET？

Can I do some kind of mixing DELETE and GET?

是的。您无需担心重写规则中的请求方法或PUT主体。

Yes. You don't need to worry about the request method or the PUT body at all in your rewrite rules.

对于您的示例，这意味着：

For your example this means:

mod_rewrite

RewriteRule book/([0-9]+) book.php?id=$1 [QSA]

HTTP请求

PUT /book/1234
=> PUT /book.php?id=1234

PHP脚本

$id = intval($_GET['id']);
if ($_SERVER['REQUEST_METHOD'] === 'PUT') {
    // yes, it is. go on as usual
}

进一步说明：GET参数和PUT之间的区别/ POST / DELETE参数是前者是URL的一部分，后者是请求体的后半部分。 mod_rewrite 仅更改网址，不会触及正文。

For further clarification: The difference between GET parameters and PUT/POST/DELETE parameters is that the former are part of the URL, the latter part of the request body. mod_rewrite only changes the URL and does not touch the body.
