nginx-基于请求的标头的响应 [英] nginx - response based on the requested header

问题描述

我已经安装了nginx 1.0.8. 这是我的问题: 我有2个文件: file1.js 和 file2.js .请求的路径是这样的:

I have nginx 1.0.8 installed. here is my problem: I have 2 files : file1.js and file2.js. the requested path is something like this:

www.mysite.com/files_dir/%user%/file.js

www.mysite.com/files_dir/%user%/file.js

如果请求的标头:" X-Header "存在且值为" OK "，则响应的内容应为file1.js，否则为file2.js.

If the requested header : "X-Header" exists and has the value "OK" then the responded content should be file1.js else file2.js.

文件位于" html/files_dir "中，％user％是一组目录，代表通过我的服务注册的用户名.

The files are situated in "html/files_dir" and %user% is a set of directories that represents the usernames registered through my service.

如何在nginx中配置它?只有对nginx可行，我对php，asp或类似技术不感兴趣.

How do I configure this in nginx? I'm not interested in php, asp or similar technologies only if it's possible with nginx.

谢谢

推荐答案

map可让您基于另一个变量定义变量的值. map应该在http级别(即在server之外)声明:

map lets you define a variable's value based on another variable. map should be declared at http level (i.e. outside of server):

map $http_x_header $file_suffix {
  default "2";
  OK      "1";
};

然后，以下location应该使用新变量$file_suffix

Then the following location should do the trick using your new variable $file_suffix

location ~ ^(/files_dir/.+)\.js$ {
  root html;
  try_files $1$file_suffix.js =404;
}
