在nginx反向代理一个带有websocket功能的spring web程序（ ）时，发现访问websocket接口时总是出现403响应，nginx的配置参考的是
我要评论
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：
通过nginx访问的日志里有这么一条：
然后google查询相关解决办法，找到github上的这个 ，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 "";
}
}
}
