Forward slashes get escaped

[pradeepsixer]

I have the following piece of code

struct json_object *claim_set = json_object_new_object();
json_object_object_add(claim_set, "iss", json_object_new_string("service_acct"));
json_object_object_add(claim_set, "scope", json_object_new_string("https://www.googleapis.com/auth/drive"));
json_object_object_add(claim_set, "aud", json_object_new_string("https://www.googleapis.com/oauth2/v4/token"));
json_object_object_add(claim_set, "iat", json_object_new_int64(epoch));
json_object_object_add(claim_set, "exp", json_object_new_int64(epoch + 3600));
printf("JSON Object : %s\n", json_object_to_json_string_ext(claim_set, JSON_C_TO_STRING_PLAIN));

And the output I get is:

{"iss":"service_acct","scope":"https:\/\/www.googleapis.com\/auth\/drive","aud":"https:\/\/www.googleapis.com\/oauth2\/v4\/token","iat":1535869316,"exp":1535872916}

Please note that the forward slashes are escaped in the stringified json, which shouldn't be.

It is something I've seen other json libraries do at times, I'll admit I'm not 100% sure why. Anyway, there's an option for that: JSON_C_TO_STRING_NOSLASHESCAPE

EDIT: just looked it up, it is in the original spec that you can escape the forward-slash, which it calls a "solidus", just in case I guess http://json.org/
