  • I am receiving a base64String for Image in response of an Api but unable to get the result through Alamofire.request method (tried with get as well as post).

     Alamofire.request(ApiUrl, method: .get, parameters: [:] , encoding:JSONEncoding.default, headers:kAuthorizationHeader).responseString { (response) in
    switch response.result {
    case .success(let responseString):
        if let imageData = Data(base64Encoded: responseString),
            let image = UIImage(data: imageData) {
            print("image")
        }
    case .failure(let error):
        print("\(error.localizedDescription)")
    }
}

  • It always returns a failure with 'requestTimeOut' in case of get method and 'Invalid value around character 0' for post.

    Is there any way through which we can get the base64String so that I can convert the same to UIImage? Please advise.

  • Can you please share some code snippet? – Bappaditya Dec 28 '18 at 05:17
  • Not a Good idea. You should discuss with your backend team to send the imageURL instead of base64String. – TheTiger Dec 28 '18 at 06:03
  • Due to security reasons/ permissions issue we cannot get url from backend. What can be other possible solution. Please share if any – Preetika Dec 28 '18 at 06:11
  • For security purpose you should user access_token or signature like AWS does. base64String can be easily convert into readable form by using online tool. – TheTiger Dec 28 '18 at 06:16
  • bease64 is large data and should not be send or receive in API if this is heavy data like image. – TheTiger Dec 28 '18 at 06:17
  • I can tell you the solution but this is not recommended. Just extract the AlamoFire and check where the URLRequest object is being initialised and set the time out aprx 10*60 so that 10 minutes and it will work. But again it will not work if the data is larger than expected. So better to follow my first comment. – TheTiger Dec 28 '18 at 06:57

I went and created a view in my python project which responds a string in a url. So using alamofire.. you need to request string rather than responseJSON

Alamofire.request("http://127.0.0.1:8000/stringResponse/", method: .get).responseString { (response) in
         switch response.result {
        case .success(let responseString):
            if let imageData = Data(base64Encoded: responseString),
                let image = UIImage(data: imageData) {
                print("image")
            }
        case .failure(let error):
            print("\(error.localizedDescription)")
        }
    }
