Sebastian Krause har fastst\u00e4llt<\/a><\/noindex> k\u00e4llan till den konstiga inkompatibiliteten med tj\u00e4nsten Bypass<\/a><\/noindex> av skriptet dehydrated<\/a><\/noindex>, som anv\u00e4nds f\u00f6r att automatisera h\u00e4mtning av TLS-certifikat via ACME-protokollet. Bypass fungerar b\u00e5de med referenskunden och uacme, men inte med dehydrated (snarare, det fungerade ocks\u00e5 med vissa genv\u00e4gar, men uteslutande i dns-1-l\u00e4get).<\/p>\n

Anledningen visade sig vara banal: ist\u00e4llet f\u00f6r att korrekt analysera svaret i JSON-format anv\u00e4nde f\u00f6rfattaren dehydrated en funktion i formateringen av den specifika JSON-utmatningen fr\u00e5n tj\u00e4nsten Let\u2019s Encrypt och gjorde analysen med hj\u00e4lp av regulj\u00e4ra uttryck. Men Bypass returnerar inte vackert formaterad, utan en minifierad JSON, och den anv\u00e4nda regulj\u00e4ra uttrycket<\/a><\/noindex> funkade inte. Den angivna metoden utesluter inte uppkomsten av problem \u00e4ven med LetsEncrypt, om denna tj\u00e4nst i framtiden utan f\u00f6rvarning \u00e4ndrar formatet p\u00e5 sin utdata, och fortfarande h\u00e5ller sig inom ramen f\u00f6r det officiella protokollet.<\/p>\n

Vid diskussionen av problemet f\u00f6reslogs det att anv\u00e4nda en extern JSON-parser, s\u00e5som json_pp<\/a><\/noindex> eller jq<\/a><\/noindex> (l\u00e4gg till i pipe 'jq -r \u00ab.authorizations | .[]\u00bb' f\u00f6r korrekt analys).
\nNackdelen med en s\u00e5dan metod \u00e4r att id\u00e9n om att klara sig med minimala och l\u00e4tt verifierbara medel f\u00f6rsvinner, liksom problem med felhantering.<\/p>\n

Skaparen av projektet dehydrated (projektet s\u00e5ldes nyligen till<\/a><\/noindex> f\u00f6retaget Apilayer GmbH) h\u00f6ll med<\/a><\/noindex>, vilket g\u00f6r JSON-analys till ett stort problem, men att l\u00e4gga till externa parserar anser han inte vara en bra id\u00e9, eftersom en av de viktigaste f\u00f6rdelarna med skriptet \u00e4r att det inte \u00e4r beroende av externa beroenden. F\u00f6r n\u00e4rvarande \u00e4r han upptagen, men hoppas kunna \u00e4gna sig \u00e5t att l\u00f6sa problemet inom de n\u00e4rmaste dagarna. Planerna inkluderar en omarbetning av JSON-parsern eller integration av en f\u00e4rdig parser p\u00e5 shell-spr\u00e5k \u2014 JSON.sh<\/a><\/noindex>.<\/p>\n
