#Nginx 用proxy_pass做反向代理返回400错误

前端web项目，经常会遇到跨域访问的问题，利用Nginx的proxy_pass可以很轻松的配置反向代理，解决这个问题。

假设资源服务器是asset-server，用以下配置，可以把asset-server/app 挂载到 server/app

  location ^~ /app {
    proxy_pass http://asset-server;
  }

这样能解决大部分的问题，但是当路径包含特殊字符，例如空格等，需要进行转义urlencode时，就回遇到问题。

需要对uri进行重写：

  location ^~ /app {
    rewrite  ^ $request_uri;            # get original URI
    rewrite  ^/app/(.*)  app/$1 break;  # drop /foo, put /bar
    return 400;   # if the second rewrite won't match

    proxy_pass http://asset-server/$uri;
  }

特别注意
如果有多层代理，每一层都需要rewrite。

  location /api/ {
    rewrite ^ $request_uri;
    rewrite ^/api/(.*) $1 break;
    return 400;
    proxy_pass http://127.0.0.1:82/$uri;
  }
