关于Nginx中的尾部斜杠行为有些困惑 [英] A little confused about trailing slash behavior in nginx

问题描述

跟踪Nginx中的Slash最近给了我一些不眠之夜.在此方面寻求帮助

Trailing Slash in nginx has been giving me some sleepless nights lately. Requesting some help with this

问题: proxy_pass中奇怪的尾部斜杠行为.

Question : Strange trailing slash behavior in proxy_pass.

那为什么行得通呢?

location /myapi/ {
      proxy_pass   http://node_server8/;
    }

这不会

location /myapi/ {
      proxy_pass   http://node_server8;
    }

请注意第二个代码块中http://node_server8末尾缺少的斜杠.这特别奇怪，因为我还有其他一些配置，其中后端没有斜杠，并且一切正常.

Notice the missing trailing slash at the end of http://node_server8 in second code block. This is specially strange as I have a few other configurations where I don't have a trailing slash on the backend and all works fine.

推荐答案

它们完全不同.

在第一个proxy_pass语句中，您包括了一个/值的URI参数.在第二次您还没有.

In the first proxy_pass statement you have included a URI parameter with a value of /. In the second you haven't.

当您给proxy_pass一个URI参数(在前缀location之内)时，它会像alias函数一样转换所请求的URI，从而用location指令的值代替URI参数.例如，/myapi/foo在变为上游之前变为/foo.

When you give proxy_pass a URI parameter (within a prefix location), it transforms the requested URI similarly to the alias function, whereby the value of the location directive is substituted for the value of the URI parameter. For example /myapi/foo becomes /foo before being passed upstream.

如果不为proxy_pass提供URI参数，则不会进行任何转换，并且请求/myapi/foo会原样传递给上游.

If you do not provide proxy_pass with a URI parameter, no transformation takes place, and the request /myapi/foo is passed upstream unchanged.
