Sebastian Krause m\u00e4\u00e4ras<\/a><\/noindex> veidra arve teenusega Bypass<\/a><\/noindex> skripti dehydrated<\/a><\/noindex>, mida kasutatakse TLS-sertifikaatide automaatseks hankimiseks ACME-protokolli kaudu. Bypass t\u00f6\u00f6tab nii etalonklientide kui ka uacme'iga, kuid mitte dehydrated'iga (t\u00e4psemalt, see t\u00f6\u00f6tas ka m\u00f5ne kahepoolse lahendusega, kuid ainult dns-1 re\u017eiimis).<\/p>\n

P\u00f5hjus osutus v\u00e4ga lihtsaks: selle asemel, et t\u00f5eliselt lahendada JSON-vastust, kasutas autor dehydrated Let's Encrypt teenuse spetsiifilist JSON-v\u00e4ljundi vormindamise omadust ja tegi lahenduse regulaaravaldiste abil. Kuid Bypass tagastab mitte korralikult vormindatud, vaid minimeeritud JSON-i, ja kasutatud regulaaravaldis<\/a><\/noindex> ei t\u00f6\u00f6tanud. Nimetatud l\u00e4henemine ei v\u00e4lista probleemide tekkimist ka LetsEncryptiga, kui teenus tulevikus formaati vahetab, j\u00e4\u00e4des samas t\u00e4ielikult ametliku protokolli raamidesse.<\/p>\n

Probleemi arutamisel pakkus keegi v\u00e4lja v\u00e4lise JSON-parseeri kasutamise, nagu json_pp<\/a><\/noindex> v\u00f5i jq<\/a><\/noindex> (lisada pipe 'jq -r \u00ab.authorizations | .[]\u00bb' \u00f5ige lahenduse jaoks).
\nSelle l\u00e4henemise miinuseks on idee h\u00e4gustamine, et hakkama saada minimaalsete ja kergesti kontrollitavate vahenditega, samuti probleemid vigade t\u00f6\u00f6tlemisel.<\/p>\n

Projekti dehydrated autor (projekt on hiljuti m\u00fc\u00fcdi<\/a><\/noindex> ettev\u00f5ttele Apilayer GmbH) n\u00f5ustus<\/a><\/noindex>, et JSON-i lahendamine on suur probleem, kuid v\u00e4listest parsi programmidest ei pea ta head ideed, kuna \u00fcheks skripti peamiseks vooruseks on s\u00f5ltumatuse puudumine v\u00e4listest s\u00f5ltuvustest. Praegu on ta h\u00f5ivatud, kuid loodab m\u00f5ne p\u00e4eva jooksul probleemile t\u00e4helepanu p\u00f6\u00f6rata. Plaanides on lisatud JSON-i parsija \u00fcmbertegemine v\u00f5i valmis shell-keeles parsija integreerimine \u2014 JSON.sh<\/a><\/noindex>.<\/p>\n
