Kauj ruam 1: Teem Koj Li Google Account

Taw qhia rau cov kauj ruam no

Peb khaws cov duab coj los ntawm Raspberry Pi ntawm Google Drive. Nyob rau sab saum toj ntawm kev zam kev sau koj Pi lub cim xeeb, qhov no yuav tso cai rau koj los tshuaj xyuas koj lub sijhawm dhau los ntawm txhua qhov chaw thoob ntiaj teb!

Google tau tshaj tawm Python pob hu ua PyDrive uas tso cai rau koj rub thiab rub cov ntawv nrog … Python!

Google muab ntau cov ntaub ntawv kom nkag siab yuav ua li cas thiaj lis PyDrive. Kuv kuj pom Annis cov ntawv qhia tau pab tau heev. Txawm li cas los xij, yog tias koj yog tus kws tshawb fawb keeb kwm zoo ib yam li kuv, txhua qhov kev siv lub ntsiab lus no (API, thaj tsam, ntws, token …) yuav nyuaj me ntsis. Yog li ntawm no yog zaj dab neeg raws li kuv nkag siab nws:

Koj tsim ib qhov haujlwm ntawm koj tus lej Google thiab pab kom tus programmer xaiv rau txoj haujlwm no. Google yuav muab koj lub npe thiab tus lej cim lej uas koj tus ntawv nab nab siv los txuas rau koj tus lej Google. Thaum txuas thawj zaug, Python siv kev tso cai "ntws" qhov twg nws qhia Google qhov kev pabcuam nws xav tau nkag mus (Cov npe ntawm cov kev pabcuam Python xav tau nkag mus hu ua "scope"). Thaum Google tau txais kev thov ntws los ntawm nab nab, nws yuav nug koj kev tso cai. Thaum koj lees txais tus kheej, Python tau txais daim ntawv pov thawj thiab tus cim to txuas nrog Google yam tsis muaj kev tso cai ntawm koj yav tom ntej.
