如何在Linux Shell中读取WebSocket响应

curl 请求的方式 不在有效 经常抛错

curl 'wss://ws.test.com' -H 'Upgrade: websocket' -H 'Connection: Upgrade' --verbose
* Protocol "wss" not supported or disabled in libcurl
* Closing connection -1
curl: (1) Protocol "wss" not supported or disabled in libcurl

更换使用 wscat

npm install -g wscat
/usr/bin/wscat -> /usr/lib/node_modules/wscat/bin/wscat
npm WARN notsup Unsupported engine for commander@9.5.0: wanted: {"node":"^12.20.0 || >=14"} (current: {"node":"8.17.0","npm":"6.13.4"})
npm WARN notsup Not compatible with your version of node/npm: commander@9.5.0
npm WARN notsup Unsupported engine for ws@8.16.0: wanted: {"node":">=10.0.0"} (current: {"node":"8.17.0","npm":"6.13.4"})
npm WARN notsup Not compatible with your version of node/npm: ws@8.16.0
