如何使用Nginx proxy_pass保留请求URL [英] How to preserve request url with nginx proxy_pass

问题描述

我正尝试使用 Thin 应用服务器，并且出现一个问题.

I was trying to use Thin app server and had one issue.

当nginx 代理使用proxy_pass http://my_app_upstream;收到对Thin(或Unicorn)的请求时，应用程序会收到由nginx(http://my_app_upstream)发送的修改后的URL.

When nginx proxies the request to Thin (or Unicorn) using proxy_pass http://my_app_upstream; the application receives the modified URL sent by nginx (http://my_app_upstream).

我想要的是传递原始URL和来自客户端的原始请求，而无需进行任何修改，因为该应用程序非常依赖它.

What I want is to pass the original URL and the original request from client with no modification as the app relies heavily on it.

nginx的文档说:

如果有必要在URI中传输URI 未经处理的形式然后指令 proxy_pass应该不带URI使用 部分.

If it is necessary to transmit URI in the unprocessed form then directive proxy_pass should be used without URI part.

但是我不知道如何正确配置它，因为相关示例实际上是使用URI:

But I don't understand how exactly to configure that as the related sample is actually using URI:

location  /some/path/ {
  proxy_pass   http://127.0.0.1;
}

所以您能帮我弄清楚如何保留来自客户端的原始请求URL 吗?

So could you please help me figuring out how to preserve the original request URL from the client?

推荐答案

我认为 proxy_set_header 指令可能会帮助:

I think the proxy_set_header directive could help:

location / {
    proxy_pass http://my_app_upstream;
    proxy_set_header Host $host;
    # ...
}
