JSON ua tsis pub "tiag" cov xov xwm tshiab hauv nws cov ntaub ntawv; nws ua tau nkaus xwb muaj khiav dim cov xov xwm tshiab . Cov "" yuav hloov nrog ASCII tswj tus cwj pwm sawv cev rau tus cwj pwm tshiab, uas yog tus cwj pwm uas tsis raug cai hauv JSON . (Raws li cov kab txuas ntxiv ua cim, nws tsuas yog siv cov kab tshiab tawm.)
Dhau li ntawd, JSON puas tuaj yeem muaj cov kab tshiab?
JSON cov hlua tsis tuaj yeem muaj cov kab tshiab los yog tabs - lawv yuav tsum tau khiav raws li los yog. (RFC xav kom tag nrho cov cim tswj tau khiav tawm.)

Tsis tas li ntawd, kab ntawv tshiab delimited JSON yog dab tsi? nd json Newline Delimited JSON NDJSON yog ib hom ntawv yooj yim rau khaws cia lossis xa cov ntaub ntawv tsim nyog uas tuaj yeem ua tiav ib cov ntaub ntawv ib zaug. Nws ua haujlwm zoo nrog unix-style text processing tools thiab plhaub pipelines. Nws kuj yog ib hom kev hloov pauv tau rau kev xa xov ntawm cov txheej txheem kev koom tes.
Raws li txoj cai, kuv yuav ntxiv kab tshiab hauv JSON li cas?
