Kungani isithombe esisodwa sihluleka kuyilapho ingxenye yekhasi isilayisha
Izimo ezintathu zehlukanisa iphutha lenethiweki kusuka kwisicelo esivinjiwe kanye nephutha lokubonisa. Thola i-URL ekhethwe isiphequluli ngaphambi kokushintsha indlela.
Ikhasi liyalayisha, umbhalo uyabonakala, kepha isithombe esisodwa sihlala siyisithonjana esiphukile. Impendulo yokuqala ukusola umhubhe, ngoba umhubhe yiwona oshintshile. Ngaphambi kwalokho, thola ukuthi isiphequluli sasicela iyiphi i-URL yaleso sithombe, ngoba i-URL yekhasi ne-URL yesithombe ziyizinto ezimbili ezihlukene zobufakazi. Iningi lemibiko yesithombe esilahlekile ligcina kusibungu esingakaze sithole isicelo esisebenzayo, futhi leyo mpendulo ibiza ukubheka okukodwa kwiphaneli yeNethiweki.
Izimo ezintathu zinquma ukuthi ubheke kuphi
Isimo sokuqala ukuthi isithombe sivela kusibungu esifanayo nekhasini yini. Isibungu sezithombe esihlukile sidinga ukuxazululwa kwamagama kwaso, uxhumano lwaso kanye nobuwena baso be-TLS, ngakho ikhasi elilayishayo alisho lutho ngaso.
Okwesibili ukuthi isiphequluli savimba isicelo ngaphambi kokusithumela yini. Okuqukethwe okuxubile, inqubomgomo yokuphepha kokuqukethwe kanye nemithetho yesikhombisi ingamisa isithombe ngaphandle kokukhiqiza impendulo evamile yesiphakeli, yingakho kungekho sicelo esihlulekile esivela ohlwini.
Okwesithathu ukuthi ukuhanjiswa kube yimpumelelo kepha ukubonisa kuhluleke, isimo lapho amabhayithi efika kodwa isithombe singaveli. Lezi zimo ezintathu zinabanikazi abathathu abehlukene, futhi eyokuqala kuphela eyombuzo wenethiweki.

Thola insiza isiphequluli esiyikhethile ngempela
I-URL oyibona kumthombo wekhasi ngokuvamile akuyona i-URL eceliwe. Amasethi wemithombo, izakhi ze-picture kanye nezimo ze-CSS zivumela isiphequluli ukuthi sikhethe enye insiza ngokusekelwe kububanzi bendawo yokubuka, ukuminyana kwamaphikseli noma ukusekelwa kwefomethi. Isithombe esilayishwa ngobuvila kungenzeka singacelwa nhlobo kuze kufike lapho ikhasi lifinyelela isimo esithile.
Hlola isakhi kanye nesicelo ndawonye, futhi gcina umqalisi nesicelo lapho ubika inkinga. Incwadi yereferensi yesakhi sesithombe ye-MDN ihlanganisa ukukhethwa komthombo, ukuziphatha kokulayisha kanye nokulawulwa kwesikhombisi endaweni eyodwa, okwanele ukusho ukuthi yisiphi isici esikhethe i-URL ehlulekile.
Qopha igama lesibungu, isimo, noma yiluphi uchungechunge lokudlulisela kwenye indawo kanye nohlobo lokuqukethwe kwimpendulo. Impendulo engu-200 ebuyisela ikhasi lokungena ayisona isithombe esisebenzisekayo, futhi ukudlulisela ekhasini lephutha le-HTML kubukeka kufana nefayela elonakele kuze kube yilapho ufunda uhlobo.
Funda isimo ngaphambi kwenethiweki
Ukuphela kwesikhathi, isicelo esenqatshiwe kanye nephutha lokuhumusha kudinga izinyathelo ezilandelayo ezihlukene, futhi ikhodi yesimo iyona ehlukanisa. Ukuphela kwesikhathi kukhombisa ukuxazululwa kwamagama, umzila noma isibungu esingaphenduli. Isicelo esenqatshiwe sikhombisa inqubomgomo noma ungqimba lokugunyaza. Iphutha lokuhumusha likhombisa amabhayithi noma ifomethi.
Uma isicelo singaveli nhlobo, yeka ukubheka inethiweki bese ubheka umaka. Isizathu esivame kakhulu ukufakwa kusethi yomthombo okwakhethwa isiphequluli futhi okungasekho kusiphakeli, kulandela isakhi iskripthi esingazange sisenze sibonakale.
Lokho kwehlukanisa kukodwa kuvimbela iningi lomzamo oyize kulolu hlobo lwemibiko.
Lapho isiphequluli sivimba, akukho mpendulo okufanele ifundwe
Okuqukethwe okuxubile yisimo sakudala: ikhasi le-HTTPS elicela isithombe nge-HTTP evamile lithola isicelo esivinjiwe esikhundleni sokuhluleka, futhi ikhonsoli iqopha isizathu. Inqubomgomo yokuphepha kokuqukethwe ikhiqiza isimo esifanayo, futhi isiyalelo esivinjiwe sishiwo kumlayezo. Inqubomgomo yesikhombisi esusa isihloko ingabangela futhi isibungu esivikelwe kuma-hotlink ukuthi sibuyisele isibambeli esikhundleni sesithombe.
Funda isizathu esiqotshelwe ngaphambi kokuthinta indlela yenethiweki, ngoba lezi zivimbelo azithuthuki lapho umzila ushintsha. Ukwengeza izimvume ze-cross-origin nakho akuyona isisombululo: ukubonisa isithombe esivela kwesinye isibungu nokufunda amaphikseli aso ku-canvas kuyimisebenzi ehlukene, futhi eyesibili kuphela edinga izihloko abantu abazinamathayo.
Kusizakala osilawulayo, lungisa i-URL yensiza, impendulo noma inqubomgomo kumnikazi wayo futhi ugcine izidingo zokugunyaza nezesikhombisi zingashintshiwe. Kusizakala ongeke usilawule, thumela ikhasi nobufakazi besicelo esiteshini sayo sokusekela esikhundleni sokuphinda ushicilele izixhumanisi zensiza eziyimfihlo noma eziphelelwa yisikhathi.
Qhathanisa izindlela ngaphandle kokushintsha ubufakazi
Uma ufuna ngempela ukuhlola indlela yokufinyelela, gcina konke okunye kungashintshiwe: ikhasi elifanayo, i-akhawunti efanayo, isithombe esikhethiwe esifanayo, indlela eyodwa evunyelwe ishintshiwe. Qhathanisa ukufakwa kwezicelo eceleni kwesinye esikhundleni somphumela obonisiwe, ngoba umphumela obonisiwe usho ukuthi isithombe savela yini, hhayi ukuthi kungani.
Isithombe esilayisha emzileni omusha asifakazisi ukuthi lowo mzila ugunyaziwe, futhi isithombe esihlala siphukile asifakazisi ukuthi umhubhe unecala. Uma isithombe sisusiwe noma ukufinyelela kukhawulelwe ngamabomu, sebenzisa enye indlela esekelwayo esikhundleni sokuvala ukuhlolwa kwesitifiketi noma ukukopisha izinto ezivikelwe zabanye.
Ukulandelana komsebenzi: khomba i-URL ekhethiwe, funda isimo sayo nohlobo, hlola ukuthi kunesizathu sokuvimbela esiqotshelwe yini, bese uqhathanisa ukushintsha kwendlela okukodwa ngesikhathi.
