hello, everybody.
in ror, we can add a after_filter to a controller.
def aes_encrypt
response.body = AesHelper.aes_encrypt(response.body)
end
after_filter :aes_encrypt
and all action's repsonse int the controller can be encrypt.
and my question is , how to decrypt data use before_filter, or anything else.
ex: i want to post json data to /usr/register, the json data is {"name":"good", "password":"nice"}. encrypt it to
5B2YC7WzgFmaivnATP1ZLR4sTXB3SsWEUeMpUbcYiylcvHxfSStYIBqwIMCjZAY3
so i post 5B2YC7WzgFmaivnATP1ZLR4sTXB3SsWEUeMpUbcYiylcvHxfSStYIBqwIMCjZAY3 to /usr/register
in action register , i would write code like this:
#### already decrypt.
def register
User.register(params[:name], params[:passport])
end
so, how can i decrypt 5B2YC7WzgFmaivnATP1ZLR4sTXB3SsWEUeMpUbcYiylcvHxfSStYIBqwIMCjZAY3 before action register to use params directly in register
thanks for anybody's help!!
