详解Nginx反向代理WebSocket响应403的解决办法

在Nginx反向代理一个带有WebSocket功能的Spring Web程序(源代码地址 )时,发现访问WebSocket接口时总是出现403响应,Nginx的配置参考的是 官方文档 :


http {
// ssl 相关配置 ...

map $http_upgrade $connection_upgrade {
    default upgrade;
    '' close;
}

server {
    listen 8020;
    location /ws {
      proxy_pass http://some-ip:8080;
      proxy_http_version 1.1;
      proxy_set_header Upgrade $http_upgrade;
      proxy_set_header Connection $connection_upgrade;
    }
}
}
唯一不同的是我们的Nginx配置了https。
于是打开Spring日志查看直接访问和通过Nginx访问的差别。
直接访问的日志:

DEBUG ... o.s.web.servlet.DispatcherServlet    : Null ModelAndView returned to DispatcherServlet with name 'dispatcherServlet': assuming HandlerAdapter completed request handling
DEBUG ... o.s.web.servlet.DispatcherServlet    : Successfully completed request
通过Nginx访问的日志:

DEBUG ... o.s.web.servlet.DispatcherServlet    : Null ModelAndView returned to DispatcherServlet with name 'dispatcherServlet': assuming HandlerAdapter completed request handling
DEBUG ... o.s.web.servlet.DispatcherServlet    : Successfully completed request
注意到直接访问的日志里有这么一条:
复制代码 代码如下:


DEBUG ... o.s.web.cors.DefaultCorsProcessor : Skip CORS processing: request is from same origin通过Nginx访问的日志里有这么一条:
复制代码 代码如下:


DEBUG ... o.s.w.s.s.s.OriginHandshakeInterceptor   : Handshake request rejected, Origin header value https://some-host.com not allowed
然后Google查询相关解决办法,找到github上的这个 issue ,所以只需要修改Nginx的配置,添加 proxy_set_header Origin ""; 就行了:


http {
// ssl 相关配置 ...

map $http_upgrade $connection_upgrade {
    default upgrade;
    '' close;
}

server {
    listen 8020;
    location /ws {
      proxy_pass http://some-ip:8080;
      proxy_http_version 1.1;
      proxy_set_header Upgrade $http_upgrade;
      proxy_set_header Connection $connection_upgrade;
      proxy_set_header Origin "";
    }
}
}
