\u00cbsht\u00eb publikuar nj\u00eb mjete me implementimin e metod\u00ebs p\u00ebr identifikimin e pajisjeve t\u00eb instaluara n\u00eb shfletuesin Chrome. Lista e marr\u00eb e pajisjeve mund t\u00eb p\u00ebrdoret p\u00ebr t\u00eb rritur sakt\u00ebsin\u00eb e identifikimit pasiv t\u00eb nj\u00eb instance specifike t\u00eb shfletuesit, n\u00eb kombinim me tregues t\u00eb tjer\u00eb t\u00ebrthor\u00eb, si\u00e7 jan\u00eb ndarja e ekranit, karakteristikat e WebGL, listat e skedar\u00ebve dhe shenjave t\u00eb instaluara. Implementimi i propozuar kontrollon instalimin e m\u00eb shum\u00eb se 1000 pajisjeve. P\u00ebr t\u00eb verifikuar sistemin tuaj, \u00ebsht\u00eb ofruar nj\u00eb demonstrim online. <\/p>\n
Identifikimi i pajisjeve b\u00ebhet p\u00ebrmes analiz\u00ebs s\u00eb burimeve t\u00eb ofruara nga pajisjet, t\u00eb disponueshme p\u00ebr k\u00ebrkesa t\u00eb jashtme. N\u00eb p\u00ebrgjith\u00ebsi, pajisjet p\u00ebrfshijn\u00eb skedar\u00eb t\u00eb ndrysh\u00ebm shoq\u00ebrues, si\u00e7 jan\u00eb imazhet, t\u00eb cilat p\u00ebrcaktohen n\u00eb manifestin e pajisjes me pron\u00ebn web_accessible_resources. N\u00eb versionin e par\u00eb t\u00eb manifestit, qasja n\u00eb burime nuk ishte e kufizuar dhe \u00e7do faqe mund t\u00eb ngarkonte burimet e ofruara. N\u00eb versionin e dyt\u00eb t\u00eb manifestit, qasja n\u00eb burime t\u00eb till\u00eb ishte lejuar si parazgjedhje vet\u00ebm p\u00ebr vet\u00eb pajisjen. N\u00eb versionin e tret\u00eb t\u00eb manifestit u ofrua mund\u00ebsia p\u00ebr t\u00eb p\u00ebrcaktuar se cilat burime mund t\u00eb dor\u00ebzoheshin p\u00ebr cilat pajisje, t\u00eb domaineve dhe faqeve. <\/p>\n
Faqet web mund t\u00eb k\u00ebrkojn\u00eb burime t\u00eb ofruara n\u00eb shtes\u00eb n\u00ebp\u00ebrmjet metod\u00ebs fetch (p.sh. \u00abfetch(\u2018chrome-extension:\/\/okb\u2026nd5\/test.png\u2019)\u00bb), ku nj\u00eb kthim i vler\u00ebs \u2018false\u2019 zakonisht tregon se shtesa nuk \u00ebsht\u00eb instaluar. P\u00ebr t\u00eb bllokuar identifikimin e shtes\u00ebs p\u00ebrmes burimeve, disa shtesa gjenerojn\u00eb nj\u00eb token verifikimi t\u00eb nevojsh\u00ebm p\u00ebr t\u00eb aksesuar burimin. Thirrja e fetch pa specifikuar tokenin gjithmon\u00eb p\u00ebrfundon me d\u00ebshtim. <\/p>\n
Si\u00e7 duket, mbrojtja e aksesit n\u00eb burimet e shtesave mund t\u00eb anashkalohet duke vler\u00ebsuar koh\u00ebn e ekzekutimit t\u00eb operacionit. Edhe pse fetch kur k\u00ebrkon pa token gjithmon\u00eb kthen nj\u00eb gabim, koha e ekzekutimit t\u00eb operacionit me dhe pa shtes\u00eb ndryshon \u2014 n\u00ebse shtesa \u00ebsht\u00eb e pranishme, k\u00ebrkesa do t\u00eb k\u00ebrkoj\u00eb m\u00eb shum\u00eb koh\u00eb sesa n\u00eb rastin kur shtesa nuk \u00ebsht\u00eb instaluar. Duke vler\u00ebsuar koh\u00ebn e reagimit, mund t\u00eb p\u00ebrcaktohet mjaft sakt\u00eb prania e shtes\u00ebs. <\/p>\n
Disa shtesa q\u00eb nuk p\u00ebrfshijn\u00eb burime t\u00eb aksesueshme jasht\u00eb mund t\u00eb p\u00ebrcaktohen p\u00ebrmes pronash shtes\u00eb. P\u00ebr shembull, shtesa MetaMask mund t\u00eb p\u00ebrcaktohet duke vler\u00ebsuar pron\u00ebn window.ethereum (n\u00ebse shtesa nuk \u00ebsht\u00eb instaluar, \u2018typeof window.ethereum\u2019 do t\u00eb kthej\u00eb vler\u00ebn \u2018undefined\u2019). \n Burimi: opennet.ru<\/a> <\/p>","protected":false,"gt_translate_keys":[{"key":"rendered","format":"html"}]},"excerpt":{"rendered":"
