webSockets yog ua raws raws li hauv qab no: Client ua HTTP thov rau server nrog "hloov dua" header ntawm qhov kev thov. Yog tias tus neeg rau zaub mov pom zoo rau kev hloov kho, ces tus neeg siv khoom thiab cov neeg rau zaub mov pauv qee cov ntaub ntawv pov thawj kev nyab xeeb thiab cov txheej txheem ntawm TCP lub qhov (socket) uas twb muaj lawm raug hloov los ntawm HTTP mus rau webSocket.
Ua li no, koj siv WebSockets li cas?
webSockets tau siv raws li hauv qab no:
- Client ua HTTP thov rau server nrog "hloov kho" header ntawm qhov kev thov.
- Yog tias tus neeg rau zaub mov pom zoo rau kev hloov kho, ces tus neeg siv khoom thiab cov neeg rau zaub mov pauv qee qhov kev lees paub kev ruaj ntseg thiab cov txheej txheem ntawm TCP lub qhov (socket) uas twb muaj lawm yog hloov los ntawm HTTP mus rau webSocket.
WebSocket siv qhov twg?
