nginx proxy_pass基于请求方法是POST，PUT还是DELETE [英] nginx proxy_pass based on whether request method is POST, PUT or DELETE

问题描述

我有两个在端口8080和9080上运行的 iKaaro 实例，其中9080实例为只读.

例如，如果请求方法是POST，PUT，DELETE，然后发送到写入实例(8080)，否则发送到9080实例，我不确定如何使用nginx.

我使用正则表达式在位置上做了一些操作，但这是不正确的.

从 http://wiki.nginx.org/HttpLuaModule 中，我看到有"HTTP可以调用的方法常量，因此添加位置块是否正确:

location ~* "(ngx.HTTP_POST|ngx.HTTP_DELETE|ngx.HTTP_PUT)" {
    proxy_pass http://127.0.0.1:8080;

谢谢

解决方案

我只是做了一个快速测试，这对我有用:

 server {
  location / {
    # This proxy_pass is used for requests that don't
    # match the limit_except
    proxy_pass http://127.0.0.1:8080;

    limit_except PUT POST DELETE {
      # For requests that *aren't* a PUT, POST, or DELETE,
      # pass to :9080
      proxy_pass http://127.0.0.1:9080;
    }
  }
}
 

I have two iKaaro instances running on port 8080 and 9080, where the 9080 instance is Read only.

I am unsure how to use nginx for example if the request method is POST, PUT, DELETE then send to write instance (8080) else send to 9080 instance.

I have done something using the location using the regex, but this is not correct.

From http://wiki.nginx.org/HttpLuaModule i see that there is the 'HTTP method constants' which can be called, so is it correct to add a location block as:

location ~* "(ngx.HTTP_POST|ngx.HTTP_DELETE|ngx.HTTP_PUT)" {
    proxy_pass http://127.0.0.1:8080;

Thanks

解决方案

I just did a quick test, and this worked for me:

server {
  location / {
    # This proxy_pass is used for requests that don't
    # match the limit_except
    proxy_pass http://127.0.0.1:8080;

    limit_except PUT POST DELETE {
      # For requests that *aren't* a PUT, POST, or DELETE,
      # pass to :9080
      proxy_pass http://127.0.0.1:9080;
    }
  }
}
