详解Nginx反向代理WebSocket响应403的解决办法

 

本篇文章主要介绍了详解Nginx反向代理WebSocket响应403的解决办法，小编觉得挺不错的，现在分享给大家，也给大家做个参考。一起跟随小编过来看看吧

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 :

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18

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：

1 2 3 4 5 6 7 8 9 10 11

通过Nginx访问的日志：

1 2 3 4 5 6 7 8 9 10 11 12

DEBUG ... o.s.web.servlet.DispatcherServlet    : DispatcherServlet with name 'dispatcherServlet' processing GET request for [/ws/gs-guide-websocket/297/jp1c3ab5/websocket] DEBUG ... s.w.s.m.m.a.RequestMappingHandlerMapping : Looking up handler method for path /gs-guide-websocket/297/jp1c3ab5/websocket DEBUG ... s.w.s.m.m.a.RequestMappingHandlerMapping : Did not find handler method for [/gs-guide-websocket/297/jp1c3ab5/websocket] DEBUG ... o.s.w.s.s.s.WebSocketHandlerMapping   : Matching patterns for request [/gs-guide-websocket/297/jp1c3ab5/websocket] are [/gs-guide-websocket/**] DEBUG ... o.s.w.s.s.s.WebSocketHandlerMapping   : URI Template variables for request [/gs-guide-websocket/297/jp1c3ab5/websocket] are {} DEBUG ... o.s.w.s.s.s.WebSocketHandlerMapping   : Mapping [/gs-guide-websocket/297/jp1c3ab5/websocket] to HandlerExecutionChain with handler [org.springframework.web.socket.sockjs.support.SockJsHttpRequestHandler@307f6b8c] and 1 interceptor DEBUG ... o.s.web.servlet.DispatcherServlet    : Last-Modified value for [/ws/gs-guide-websocket/297/jp1c3ab5/websocket] is: -1 DEBUG ... o.s.w.s.s.t.h.DefaultSockJsService    : Processing transport request: GET http://localhost:8080/ws/gs-guide-websocket/297/jp1c3ab5/websocket DEBUG ... o.s.w.s.s.s.OriginHandshakeInterceptor  : Handshake request rejected, Origin header value https://some-host.com not allowed DEBUG ... o.s.w.s.s.s.HandshakeInterceptorChain  : org.springframework.web.socket.server.support.OriginHandshakeInterceptor@25ce6ad4 returns false from beforeHandshake - precluding handshake 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：

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19

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 "";     }   } }
