NGINX: invalid number of arguments in "proxy_set_header" while configuring websockets

问题

I am trying to configure nginx for websockets.
But it returns an error.

[emerg] 8#8: invalid number of arguments in "proxy_set_header" directive in /etc/nginx/conf.d/default.conf:45 nginx: [emerg] directive in /etc/nginx/conf.d/default.conf:45

Error occurs in line 45, that's:
proxy_set_header Upgrade $http_upgrade;

I have no idea why it doesn't work, I copied it from nginx docs.

Looking for solutions I tried adding a \ before the $, switching nginx version.
It didn't help.

  1. location /ws/ {
  2.     proxy_pass http://backend;
  3.     proxy_http_version 1.1;
  4.     proxy_set_header Upgrade $http_upgrade;
  5.     proxy_set_header Connection "upgrade";
  6. }

  53.     }

  57.     location = /50x.html {
  58.         root /usr/share/nginx/html;
  59.     }
  60. }

Any idea what I should change to make it work?

我认为我可以将proxy_set_header放入另一个文件中，然后使用include。<br/>
它有效。
我创建了一个名为proxy_params的文件，在其中我放置了以下内容

proxy_params

  1. proxy_set_header Upgrade $http_upgrade;
  2. proxy_set_header Connection "upgrade";

然后在配置文件中我使用了
include /etc/nginx/proxy_params;
<br/>

这是我的WebSocket配置

default.conf - WebSocket配置

  1. location /ws/ {
  2.     proxy_pass http://backend;
  3.     proxy_http_version 1.1;
  4.     include /etc/nginx/proxy_params;
  5. }
英文:

I thought I could put proxy_set_header into another file, then use include. <br/>
It works.
I created a file called proxy_params, in which I put the following

proxy_params

  1. proxy_set_header Upgrade $http_upgrade;
  2. proxy_set_header Connection &quot;upgrade&quot;;

Then in the configuration file I used

include /etc/nginx/proxy_params;

<br/>

This is what my config for websockets looks like

default.conf - websocket config

  1. location /ws/ {
  2.     proxy_pass http://backend;
  3.     proxy_http_version 1.1;
  4.     include /etc/nginx/proxy_params;
  5. }
