ruby - How do I remove backslashes from a JSON string? -

-

i have json string looks below

'{\"test\":{\"test1\":{\"test1\":[{\"test2\":\"1\",\"test3\": \"foo\",\"test4\":\"bar\",\"test5\":\"test7\"}]}}}'

i need change 1 below using ruby or rails:

'{"test":{"test1":{"test1":[{"test2":"1","test3": "foo","test4":"bar","test5":"bar2"}]}}}'

i need know how remove slashes.

use ruby's string#delete! method. example:

str = '{\"test\":{\"test1\":{\"test1\":[{\"test2\":\"1\",\"test3\": \"foo\",\"test4\":\"bar\",\"test5\":\"test7\"}]}}}' str.delete! '\\' puts str #=> {"test":{"test1":{"test1":[{"test2":"1","test3": "foo","test4":"bar","test5":"test7"}]}}}
