端口号8088
1.服务器端代码：
@Component
@ServerEndpoint("/websocket")
public class WebSocket {
private Session session;
private String name;
private static ConcurrentHashMap<String,WebSocket> LinkDeviceMap = new ConcurrentHashMap<>();
private static ConcurrentHashMap<String,WebSocket> LinkPhoneMap= new ConcurrentHashMap<>();
private static CopyOnWriteArraySet<WebSocket> webSockets = new CopyOnWriteArraySet<>();
@OnOpen
public void OnOpen(Session session){
this.session = session;
webSockets.add(this);
System.out.println("[WebSocket] 连接成功");
}
@OnClose
public void OnClose(){
webSockets.remove(this);
System.out.println("[WebSocket] 退出成功");
}
@OnMessage
public void OnMessage(String message) throws IOException {
System.out.println("[WebSocket] 收到的消息"+message);
}
}
}
2.Nginx配置：
server {
listen 8087;
server_name localhost;
client_header_buffer_size 16k;
large_client_header_buffers 4 256k;
# 允许跨域
add_header Access-Control-Allow-Origin *;
add_header Access-Control-Allow-Methods 'GET, POST, OPTIONS';
add_header Access-Control-Allow-Headers 'DNT,X-Mx-ReqToken,Keep-Alive,User-Agent,X-Requested-With,If-Modified-Since,Cache-Control,Content-Type,Authorization';
#charset koi8-r;
#access_log logs/host.access.log main;
location / {
root html;
index index.html index.htm;
proxy_pass http://xxxxxxxxx:8088/websocket;
# proxy_pass http://websocket/websocket; #转发
proxy_set_header Host $host;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-For $remote_addr;
proxy_http_version 1.1;
proxy_set_header Upgrade $http_upgrade;
proxy_set_header Connection "upgrade";
}
手机和h5测试ws://xxxxxxxx:8087可以连接websokcet通讯，没有问题，nginx转发websocket没有问题 但是硬件设备和sokit测试工具连接报错400 bad request
