如果条件在nginx conf中的位置块内工作怎么办？

Question

location /x/ {

  limit_conn x 500;

  add_header Access-Control-Allow-Origin *;

  allow all;

  proxy_http_version 1.1;

  proxy_set_header Upgrade $http_upgrade;

  proxy_set_header Connection $http_connection;

  chunked_transfer_encoding off;

  proxy_buffering off;

  proxy_cache off;

  proxy_read_timeout 2073600;

  if ($http_upgrade = websocket) {

   proxy_pass        http://x;

  }
  if ($http_upgrade != websocket) {

   proxy_pass        http://y;

  }

}

在这里，我想制作＆＃34; websocket＆＃34; 不区分大小写（忽略大小写）。如何制作？我自己尝试过一些东西。像：

1.

if ($http_upgrade = ~*websocket) {

   proxy_pass        http://x;
  }

if ($http_upgrade != ~*websocket) {

  proxy_pass        http://y;
  }

2.

if ($http_upgrade = "(?i) websocket") {

proxy_pass        http://x;
  }

if ($http_upgrade != "(?i) websocket") {

proxy_pass        http://y;
  }

但两种情况都不起作用。

Answer 1

请尝试这些：

if ($http_upgrade == "websocket") 
{
    proxy_pass        http://x;
}
if ($http_upgrade != "websocket") 
{
    proxy_pass        http://y;
}

或

if ($http_upgrade == "websocket") 
{
    proxy_pass        http://x;
 }
else
{
    proxy_pass        http://y;
}
