IiWebSockets zinokuba phezulu kwizaziso ze-dApp Web3 kuba benza ukuba izaziso zexesha lokwenyani zeziganeko ezibalulekileyo ngokuqhubekayo ngokuchasene nezicelo zomntu ngamnye.
Nge-HTTP, uxhulumaniso ngalunye luqala xa umxhasi enza isicelo kwaye aphelise uxhulumaniso xa isicelo sanelisiwe.
I-WebSocket yinkqubo yonxibelelwano yeendlela ezimbini eyenza iiseshoni zokunxibelelana phakathi komthengi kunye nomncedisi . Isekelwe kwi-TCP kwaye isoloko isetyenziselwa usetyenziso kunye neenkonzo ezifuna amandla okwazisa ngexesha lokwenyani.
Umncedisi weWebSocket sisicelo esimamelayo kwi-port ye-TCP, ngokulandela iprotocol ethile. I-WebSocket yindlela yokunxibelelana yonxibelelwano phakathi komthengi kunye nomncedisi, ovumela ukuba bobabini bacele kwaye bathumele idatha komnye nomnye.
Ngokwahlukileyo, i-HTTP yinkqubo yonxibelelwano yendlela enye, apho umxhasi angathumela kuphela izicelo kumncedisi kwaye umncedisi angathumela kuphela idatha ekuphenduleni, ungalokothi umncedisi kubudlelwane be-HTTP angacela kumxhasi.
Uqhagamshelwano lweWebSocket lunxibelelwano oluqhubekayo phakathi komxhasi kunye nomncedisi, ngelixa udibaniso lwe-HTTP lukunye kuphela. Uxhulumaniso luqala ngesicelo ngasinye umthengi asenzayo kumncedisi kwaye uphela ngempendulo yomncedisi. Uqhagamshelwano lweWebSocket lunokugcinwa nje ngokuba umxhasi kunye nabancedisi bafuna ukuba bavule, oku kuthetha ukuba idatha inokuhamba kuloo WebSocket ixesha elide njengoko amaqela efuna, konke kwisicelo sokuqala.
IWebSocket isebenzisa umthetho olandelwayo weWS, osekwe kwiProtocol yoLawulo lokuThunyelwa (TCP) . Inethiwekhi ejolise kunxibelelwano, oku kuthetha ukuba uxhulumaniso kufuneka lusekwe kuqala phakathi kwabathathi-nxaxheba ukuhambisa idatha kwindawo echanekileyo.
Endaweni yoko, iProtocol ye-Intanethi imisela apho idatha ithunyelwa khona ngokusekelwe kulwazi olungaphakathi kwepakethi yedatha; akukho lungelelwaniso lwangaphambili olufunekayo ukuze uhambise ipakethi.
Kukho iindlela ezimbini zomncedisi ukuthumela idatha kumxhasi. Umxhasi unokucela rhoqo idatha kumncedisi, owaziwa ngokuba ukuvota , okanye umncedisi angathumela ngokuzenzekelayo idatha kumxhasi, owaziwa ngokuba iseva push .
I-WebSocket APIs iphakamisa uxhulumaniso phakathi komxhasi kunye nomncedisi ngokuhlala evulekile emva kwesicelo sokuqala sokusebenzisa ubuchule bokutyhala umncedisi, ukususa uxinzelelo lweziseko ezingundoqo olwenziwa ngabathengi bahlala bevotela umncedisi wohlaziyo olutsha.
I-WebSockets yindlela yokunxibelelana ngeendlela ezimbini, evumela iimpendulo ezininzi kwisicelo somncedisi omnye. IiWebSockets zikwasetyenziselwa ikakhulu unxibelelwano lwe-client-server, ngelixa ii-webhooks zisetyenziselwa ikakhulu unxibelelwano lweseva.
Ngokungafaniyo neWebSockets, iiwebhooks , ezisebenzisa i-HTTP, zingqongqo ngendlela enye: umncedisi uphendula izicelo kuphela xa isicelo senziwe, kwaye lonke ixesha linelisekile, uxhumano luphukile.
Urhwebo phakathi kokusebenzisa iWebSockets okanye iiwebhooks luvela kwinto yokuba uyilo lweziseko zophuhliso lunokusingatha ngcono uqhagamshelo oluninzi lweWebSocket oluvulwe kanye kunezicelo ezininzi zokuqhagamshelwa kwewebhu kubathengi.
Ukuba isicelo sakho somncedisi sisebenza njengomsebenzi welifu (AWS Lambda, Google Cloud Functions, njl.), sebenzisa iiwebhooks kuba usetyenziso aluyi kugcina imidibaniso yeWebSocket ivuliwe.
Kwimeko apho inani lezaziso ezithunyelweyo lisezantsi, iiwebhooks nazo ziphezulu njengoko uqhagamshelo luqalwa kuphela ukuba isiganeko senzeka.
Ukuba isiganeko sinqabile, kungcono ukusebenzisa i-webhooks kunokugcina uqhagamshelo oluninzi lweWebSocket luvulekile phakathi kwabaxhasi kunye neeseva.
Okokugqibela, nokuba uzama ukuqhagamshela umncedisi nomnye umncedisi okanye umxhasi kunye nomncedisi ubalulekile; iiwebhooks zingcono kweyangaphambili, iiWebSockets zezokugqibela.
Kwii-Web3 dApps ezininzi kunyanzelekile ukuhlaziya abasebenzisi babo ngexesha lokwenyani kwimeko yentengiselwano yabo. Ngaphandle koko, banokuba namava omsebenzisi ahlwempuzekileyo kwaye balahle i-app yakho okanye inkonzo.
I-WebSockets kufuneka isetyenziswe kwizicelo ze-HTTP nanini na xa ixesha lokulinda kufuneka libe phantsi kangangoko. Ngokwenza oku siqinisekisa ukuba abasebenzisi bafumana izaziso malunga neziganeko ngokukhawuleza ukuba zisenzeka. I-HTTP icotha kakhulu ngenxa yokuba umxhasi ulinganiselwe kwindlela anokufumana ngayo uhlaziyo ukuba ithumela kangaphi izicelo.
