需要拼接的那个转码

解决方法

 func addEncoding(st : String ) ->String? {
        if #available(iOS 7.0, OSX 10.9, *) {
            return st.stringByAddingPercentEncodingWithAllowedCharacters(.URLHostAllowedCharacterSet())
        }
        else {
            return  st.stringByAddingPercentEscapesUsingEncoding(NSUTF8StringEncoding)
        }
    }
//拼接
 request.strUrl = MESUBCRIPTION_URL + User.currentUser().token + "?categories=" + addEncoding(strsub)!
