Spring WebSocket:由于无效的升级标头，握手失败:null [英] Spring WebSocket: Handshake failed due to invalid Upgrade header: null

问题描述

我正在使用wss(安全的Web套接字)以及来自后端的spring和用于JavaScript客户端的STOMP.

I am using wss (secured web sockets) with spring from backend and STOMP for javascript client.

有人知道为什么要得到吗?

Does anyone knows why a get:

Handshake failed due to invalid Upgrade header: null

推荐答案

我在使用tomcat的nginx https代理时遇到了同样的问题.这是因为我不支持wss请求.为了支持wss请求，我使用如下配置:

I met the same problem with nginx https proxy to tomcat. This is because I haven't support the wss request. To support the wss request, I use the config like below:

# WebSocketSecure SSL Endpoint
#
# The proxy is also an SSL endpoint for WSS and HTTPS connections.
# So the clients can use wss:// connections 
# (e.g. from pages served via HTTPS) which work better with broken 
# proxy servers, etc.

server {
    listen 443;

    # host name to respond to
    server_name ws.example.com;

    # your SSL configuration
    ssl on;
    ssl_certificate /etc/ssl/localcerts/ws.example.com.bundle.crt;
    ssl_certificate_key /etc/ssl/localcerts/ws.example.com.key;

    location / {
        # switch off logging
        access_log off;

        # redirect all HTTP traffic to localhost:8080
        proxy_pass http://localhost:8080;
        proxy_set_header X-Real-IP $remote_addr;
        proxy_set_header Host $host;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;

        # WebSocket support (nginx 1.4)
        proxy_http_version 1.1;
        proxy_set_header Upgrade $http_upgrade;
        proxy_set_header Connection "upgrade";
    }
}
