详解详解Nginx反向代理反向代理WebSocket响应响应403的解决办法的解决办法

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：

注意到直接访问的日志里有这么一条：

代码如下:

通过Nginx访问的日志里有这么一条：
