Sebastian Krause determinou<\/a><\/noindex> a fonte da estranha incompatibilidade com o servi\u00e7o Bypass<\/a><\/noindex> do script dehydrated<\/a><\/noindex>, usado para automatizar a obten\u00e7\u00e3o de certificados TLS pelo protocolo ACME. Com o Bypass, tanto o cliente de refer\u00eancia quanto o uacme funcionam, mas n\u00e3o o dehydrated (na verdade, ele tamb\u00e9m funcionou com algumas manobras alternativas, mas exclusivamente em modo dns-1).<\/p>\n

A raz\u00e3o era banal: em vez de analisar a resposta no formato JSON de verdade, o autor dehydrated usou uma caracter\u00edstica de formata\u00e7\u00e3o espec\u00edfica da sa\u00edda JSON do servi\u00e7o Let's Encrypt e fez a an\u00e1lise usando uma express\u00e3o regular. Mas o Bypass retorna um JSON minimizado em vez de um JSON bem formatado, e o utilizado regular<\/a><\/noindex> n\u00e3o funcionou. A abordagem indicada n\u00e3o exclui o surgimento de problemas com o LetsEncrypt, caso esse servi\u00e7o mude sem aviso pr\u00e9vio o formato de sa\u00edda, permanecendo dentro dos limites do protocolo oficial.<\/p>\n

Durante a discuss\u00e3o do problema, foi proposto usar um analisador JSON externo, como json_pp<\/a><\/noindex> ou jq<\/a><\/noindex> (adicione ao pipe 'jq -r \u00ab.authorizations | .[]\u00bb' para uma an\u00e1lise correta).
\nA desvantagem dessa abordagem \u00e9 que dilui a ideia de se utilizar ferramentas m\u00ednimas e facilmente verific\u00e1veis, al\u00e9m de trazer problemas com o tratamento de erros.<\/p>\n

O autor do projeto dehydrated (o projeto foi recentemente vendido<\/a><\/noindex> para a empresa Apilayer GmbH) concordou<\/a><\/noindex>, que analisar JSON \u00e9 um grande problema, mas adicionar parsers externos n\u00e3o \u00e9 considerado uma boa ideia, j\u00e1 que uma das principais vantagens do script \u00e9 a aus\u00eancia de depend\u00eancias externas. Atualmente, ele est\u00e1 ocupado, mas espera dedicar aten\u00e7\u00e3o \u00e0 solu\u00e7\u00e3o do problema nos pr\u00f3ximos dias. Est\u00e1 nos planos uma revis\u00e3o do parser JSON ou a integra\u00e7\u00e3o de um parser pronto em shell \u2014 JSON.sh<\/a><\/noindex>.<\/p>\n
