REST web service tsis muaj dab tsi tab sis hu HTTP. REST cov kev pab cuam tsis muaj dab tsi ua nrog Synchronous los yog asynchronous . Client Side: Cov neeg siv khoom hu yuav tsum txhawb nqa asynchronous kom ua tiav nws zoo li AJAX hauv browser. Server Side: Multi- Xov ib puag ncig / Tsis thaiv IO yog siv los ua kom tiav asynchronous kev pabcuam.

Ib yam li ib tug yuav nug, yog http synchronous lossis asynchronous?

HTTP yog a synchronous raws tu qauv: tus neeg thov kev thov thiab tos rau cov lus teb. Nyob rau hauv sib piv rau HTTP , cov lus hla (piv txwv li dhau AMQP, lossis ntawm Akka cov neeg ua yeeb yam) yog asynchronous . Raws li tus neeg xa khoom, feem ntau koj tsis tos kom teb.

Tsis tas li ntawd, synchronous thiab asynchronous integration yog dab tsi? Hauv synchronous kev sib txuas lus, ib daim ntawv thov xa ntawv xa mus rau daim ntawv thov txais thiab yuav tsum tau tos kom teb ua ntej nws tuaj yeem txuas ntxiv nrog nws cov txheej txheem. Hauv asynchronous kev sib txuas lus, ib daim ntawv thov xa ntawv xa mus rau ib daim ntawv thov txais thiab txuas ntxiv nws cov txheej txheem ua ntej tau txais cov lus teb.

Cov lus nug tseem yog, puas so txhawb asynchronous?

Asynchronous qauv rau REST kev pabcuam tsis yog txhawb hauv qhov kev tso tawm no. Hom kev pabcuam no muab cov lus teb tam sim rau cov lus nug. Hauv qhov xwm txheej no, tus neeg siv yuav tos kom txog thaum lub server xa rov qab cov lus teb.

Dab tsi yog synchronous thiab asynchronous API?
