Kev Cai Buffers ( Protobuf ) yog ib txoj kev serializing cov ntaub ntawv tsim nyog. Nws yog ib qho tseem ceeb hauv kev tsim cov kev pab cuam los sib txuas lus nrog ib leeg dhau ib lub xaim lossis khaws cov ntaub ntawv. Cov qauv ntaub ntawv (hu ua lus) thiab cov kev pabcuam tau piav qhia hauv cov ntaub ntawv txhais lus proto (. proto) thiab muab tso ua ke nrog protoc.
Cov lus nug tseem yog, vim li cas peb thiaj xav tau Protobuf?
Cov txheej txheem buffers , feem ntau hu ua Protobuf , yog ib txoj kev tsim los ntawm Google kom tso cai rau serialization thiab deserialization ntawm cov ntaub ntawv tsim. Google tsim nws nrog lub hom phiaj los muab txoj hauv kev zoo dua, piv rau XML, ua kom sib txuas lus.
Ib sab saum toj no, Protobuf compiler yog dab tsi? Kev Cai Buffers (a.k.a., ib. ua protobuf ) yog Google cov lus-nruab nrab, platform-nruab nrab, txuas ntxiv mechanism rau serializing cov ntaub ntawv tsim qauv. Rau nruab ua protobuf , koj yuav tsum tau nruab cov txheej txheem compiler (siv rau sau ua ke . proto cov ntaub ntawv) thiab cov ua protobuf runtime rau koj xaiv hom lus programming.
Tsis tas li ntawd, Google Protobuf ua haujlwm li cas?
Protobuf yog cov ntaub ntawv serializing raws tu qauv zoo li JSON lossis XML. Koj txhais tau li cas koj xav kom koj cov ntaub ntawv raug teeb tsa ib zaug, tom qab ntawd koj tuaj yeem siv cov cai tshwj xeeb tsim los yooj yim sau thiab nyeem koj cov ntaub ntawv tsim los thiab los ntawm ntau cov ntaub ntawv ntws thiab siv ntau hom lus.
Puas yog Protobuf sai dua JSON?
Protobuf yog ca3x sai dua Jackson thiab 1.33x sai dua DSL- JSON rau integer encoding. Protobuf tsis tseem ceeb sai dua ntawm no. Qhov optimization siv los ntawm DSL- JSON nyob ntawm no.

Cell referencing yog dab tsi thiab dab tsi yog qhov sib txawv ntawm kev xa tawm?
Muaj ob hom kev siv ntawm tes: txheeb ze thiab tsis meej. Cov txheeb ze thiab cov ntawv pov thawj tseeb coj txawv txawv thaum theej thiab sau rau lwm lub hlwb.Cov ntaub ntawv txheeb ze hloov thaum tus qauv raug theej rau lwm lub xovtooj. Cov ntaub ntawv tseeb, ntawm qhov tod tes, tseem nyob tas li txawm tias lawv tau theej qhov twg

Social engineering yog lo lus siv rau ntau yam kev ua phem ua phem uas ua tiav los ntawm tib neeg kev sib cuam tshuam. Nws siv kev puas siab puas ntsws los ntxias cov neeg siv kom ua yuam kev kev ruaj ntseg lossis muab cov ntaub ntawv rhiab
Protobuf compiler yog dab tsi?
Protocol Buffers (a.k.a., protobuf) yog Google cov lus-nruab nrab, platform-neutral, extensible mechanism rau serializing cov ntaub ntawv. Txhawm rau nruab protobuf, koj yuav tsum teeb tsa cov txheej txheem compiler (siv los sau cov ntaub ntawv proto) thiab lub sijhawm ua haujlwm protobuf rau koj cov lus xaiv programming
