Muab tshuaj txhuam qhov url rau hauv cov ntawv sau lossis sau ntawv rau tam sim no.
Ua piv txwv, txhawm rau khawb Christmas Pob Zeb, qhov url yuav yog: (peb tsis xav tau cov lus piav qhia server)
ice4.somafm.com/xmasrocks-128-mp3
Nws tau txais me ntsis dicier sab nraum lub ntiaj teb ntawm SomaFm. Ntau lub chaw siv tus neeg nruab nrab nruab nrab ntawm tus mloog thiab lub chaw nres tsheb, txawm tias nws yog rau kev tshaj tawm, kev lag luam lossis tej zaum yuav taug qab - thiab kuv feem ntau sim zam cov hom kev noj haus no. Txij li cov neeg nruab nrab xav kom koj mloog lub chaw nres tsheb hla lawv, feem ntau nws tsis yooj yim mus nrhiav qhov url; thiab qhov ntawd yog qhov uas Vtuner nkag los.
*Kuv yuav tsis nco yog tias kuv tsis tau thov kom koj txiav txim siab muab nyiaj pub dawb rau koj lub xov tooj cua uas koj nyiam, vim tias ntau lub chaw tso siab rau tus neeg mloog nkaus xwb.
Kauj Ruam 6: Xaiv tau: Khaws URL's Siv Vtuner
Tam sim no los txog qhov lom zem…. Ntawm Vtuner home page, txheeb xyuas lawv cov chaw nres tsheb loj loj txuas rau ntawm kaum sab xis. Xaiv ib hom nkauj uas koj nyiam, thiab tom qab ntawd txheeb xyuas qhov nrawm tshaj plaws, qhov twg koj yuav pom cov npe ntawm cov chaw nres tsheb. Xaiv qhov chaw nres tsheb uas koj xav tias koj yuav nyiam, nyem rau ntawm qhov txuas lossis khawm ua si thiab coj cov nkauj tawm. Yog tias nws tsis yog rau koj, tsis muaj kev txhawj xeeb, rov ua cov txheej txheem kom txog thaum peb pom ib qho haum rau kev lom zem mus sij hawm ntev. Hauv kuv qhov screen txhaj tshuaj, Kuv tau xaiv qhov digital impulse version ntawm Lub Tebchaws nkauj thiab ntawm lub vijtsam tom ntej, Kuv pom tias nws tau tawm ntawm Croatia. Lub Tebchaws Suab Nkauj los ntawm Croatia suab zoo li nthuav.
Kuv nyiam nws Tab sis kuv yuav ua li cas thiaj tau qhov url? Cias ua txoj nyem rau ntawm qhov chaw dawb rau sab xis ntawm daim duab chaw nres tsheb, hauv qab lub npe Chaw Nres Tsheb, thiab xaiv "Saib Nplooj Ntawv Source" thiab nqes mus txog kab 150.
