Nginx 支持webSocket 响应403

2019独角兽企业重金招聘Python工程师标准>>>

web项目为了解决并发连接数，并发现在数，下载流量问题，我在我们项目引入了nginx。最近项目加入websocket协议，集成推送功能。突然发现，nginx代理不了了，响应403.

网上找了些列子，包括官网http://nginx.org/en/docs/http/websocket.html  给出的配置内容：

location /chat/ {
    proxy_pass http://backend;
    proxy_http_version 1.1;
    proxy_set_header Upgrade $http_upgrade;
    proxy_set_header Connection "upgrade";
}

然而并没有什么卵用。配置完后错误还是没有解决。最终费了好大力气。找到解决方法：

 # Pass the csrf token (see https://de.wikipedia.org/wiki/Cross-Site-Request-Forgery)
    # Default in Spring Boot and required. Without it nginx suppresses the value
    proxy_pass_header X-XSRF-TOKEN;

    # Set origin to the real instance, otherwise a of Spring security check will fail
    # Same value as defined in proxy_pass
    proxy_set_header Origin "http://testsysten:8080"; 

添加以上两句就ok了。原因（自行翻译）：

Nginx needs to pass some additional header values if you want to use Websocket and Spring Security. The following lines need to be added to locationsection in your Nginx config。
