PubNub yog Protocol Agnostic lossis Independent. PubNub tau siv ntau yam kev cai raws sij hawm, xws li WebSockets , MQTT, COMET, BOSH, SPDY, kev xaiv tsa ntev thiab lwm tus, thiab peb tab tom tshawb nrhiav cov qauv tsim siv HTTP 2.0, thiab lwm yam.
Hauv qhov no, PubNub siv rau dab tsi?
PubNub tuaj yeem yog siv txhawm rau thawb cov lus me me mus rau ib lossis ntau yam khoom siv (smartphones, ntsiav tshuaj, desktops, microcontrollers, thiab lwm yam) - qhov tseem ceeb, tsuas yog hais txog txhua yam khoom siv uas tuaj yeem ua TCP / IP txuas rau hauv internet - zoo li rov qab los dua, rau kev sib txuas lus ntawm ob qho tib si..
Tom qab ntawd, lo lus nug yog, yog WebSocket UDP lossis TCP? WebSockets , ntawm qhov tod tes, tso cai rau kev xa xov raws cov ntaub ntawv, zoo ib yam li UDP , tab sis nrog kev ntseeg ntawm TCP . WebSocket siv HTTP raws li kev thauj khoom thawj zaug, tab sis khaws cia TCP kev sib txuas ciaj sia tom qab HTTPresponse tau txais kom nws tuaj yeem siv rau kev xa cov lus ntawm cov neeg siv khoom thiab cov neeg rau zaub mov.
Thaum twg koj yuav siv WebSocket?
Tej zaum koj yuav siv WebSockets tsis raug yog tias:
- Kev sib txuas tsuas yog siv rau cov xwm txheej tsawg heev, lossis lub sijhawm me me, thiab tus neeg siv khoom tsis xav tau nrawm nrawm rau cov xwm txheej.
- Koj qhov tshwj xeeb xav tau ntau qhov WebSockets qhib rau tib qhov kev pabcuam ib zaug.
Puas yog cov ntawv ceeb toom thawb siv WebSockets?
Qhov feem ntau piv txwv rau WebSockets yog chat los yog thawb cov ntawv ceeb toom . Lawv ua tau siv rau cov ntawv thov no, tab sis nthuav tawm cov kev daws teeb meem overkill rau cov teeb meem, txij li hauv cov ntawv thov no tsuas yog cov neeg rau zaub mov xav tau thawb cov ntaub ntawv rau cov neeg siv khoom, thiab tsis yog lwm txoj kev nyob ib puag ncig - tsuas yog ib nrab-duplex kev sib txuas yog xav tau.

Kuv puas tuaj yeem txuas cov khoom siv tsis yog PoE mus rau PoE hloov chaw PoE? Yog, koj ua tau. AllEnGenius PoE keyboards muaj qhov pib-sensing PoE ports.Qhov no txhais tau hais tias qhov chaw nres nkoj PoE yuav ntes yog tias cov khoom siv txuas nrog yog PoE ntaus ntawv lossis tsis yog
Kuv puas tuaj yeem siv LastPass ntawm ntau yam khoom siv?
Tam sim no koj tuaj yeem siv LastPass ntawm MultipleDevices dawb. Pib hnub no, LastPass yuav tsis them nyiaj ntxiv rau kev nkag mus rau koj tus password vault los ntawm ntau hom khoom siv. Qhov ntawd txhais tau tias cov neeg siv dawb tam sim no tuaj yeem nkag mus rau lawv tus password vaults ntawm lawv lub xov tooj thiab lawv lub desktop tsis muaj nqi ntxiv
WebSockets siv li cas?
WebSockets tau ua raws li hauv qab no: Cov neeg siv ua HTTP thov rau server nrog 'kho dua tshiab' 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 yog hloov los ntawm HTTP mus rau webSocket
Kuv yuav tsum siv WebSockets?
Thaum tus neeg siv yuav tsum tau hnov mob sai rau qhov kev hloov pauv (tshwj xeeb tshaj yog ib qho nws tsis tuaj yeem kwv yees), WebSocket yuav yog qhov zoo tshaj plaws.Xav txog daim ntawv thov kev sib tham uas tso cai rau ntau tus neeg siv sib tham hauv lub sijhawm. Yog tias siv WebSockets, txhua tus neeg siv tuaj yeem xa thiab tau txais cov lus hauv lub sijhawm
