Sto cercando di analizzare una stringa JSON che ho ricevuto da Twitter come risposta tramite l'API RESTful. Volevo utilizzare la gemma JSON, ma ho riscontrato un problema. Secondo la documentazione, sembra che il parser JSON restituisca un hash, che è quello che voglio. Tuttavia, quando eseguo effettivamente JSON.parse (twitter_result.body), restituisce una matrice. Come posso ottenere il parser JSON per restituire un hash?Ruby JSON.parse restituisce una matrice
Questo è il parser che sto usando: http://www.ruby-doc.org/stdlib-1.9.3/libdoc/json/rdoc/JSON.html#method-i-parse
"Pretty" output di esempio JSON:

Messaggio 'twitter_result.body' e l'uscita parser. – rohit89
L'output Parser è solo un oggetto. Come dovrei dimostrarlo? – csnate
Ovviamente restituisce un array, il tuo JSON inizia con un '[' – Stefan
