Question:

Use nginx to configure the ssl certificate. When deploying the project, it is found that the ws protocol has failed and must be changed to the wss protocol. Websocket uses ws or wss, which is similar to HTTP or HTTPS, where wss represents Websocket on top of TLS, which is equivalent to HTTPS. By default, Websocket's ws protocol uses port 80. When running on TLS, the wss protocol uses port 443 by default.

Solution method

Refer to the official document: http://nginx.org/en/docs/http/websocket.html

Add the following configuration to nginx:

Location / websocket {proxy_pass http://myblog.lwenhao.com:8080/myblog/websocket; proxy_http_version 1.1; proxy_set_header Upgrade $http_upgrade; proxy_set_header Connection "upgrade";}

Need the agent to forward to your real websocket address. I applied for a free ssl certificate for the domain name on Ali. The front end can only request it through the domain name applying for the certificate, not through the first-and second-level domain names.

Note:

By default, if the proxy server does not transfer any data within 60 seconds, the connection is closed. Use the proxy_read_timeout directive to increase this timeout. Alternatively, the proxy server can be configured to send WebSocket ping frames periodically to reset the timeout and check if the connection still exists.
