Loxone miniserver socket connect in iOS swift

[qadirsuh]

I am trying to acquire tokens in iOS. I am following your code of javascript and re-writing it in iOS swift.

here is my code. and LOGs in comments

    ```
    func connectToServer2(_ user:NSString ,password:NSString, address:NSString ,command :NSString ) {        
    let urlString = NSString(format:"%@%@", address,command) as String
    let getKey2url = URL(string: urlString)

    print("getKey2 Url", String(describing: getKey2url)); // 

    Alamofire.request(getKey2url!, method: .get, parameters: nil, encoding: JSONEncoding.default)
        .downloadProgress(queue: DispatchQueue.global(qos: .utility)) { progress in
            print("Progress: \(progress.fractionCompleted)")
        }
        .validate { request, response, data in
            // Custom evaluation closure now includes data (allows you to parse data to dig out error messages if necessary)
            //print("response", response);
            return .success
        }
        .responseJSON { response in
            //debugPrint(response)
            //print("JSON req", response)

            if((response.result.value) != nil) {

                let swiftyJSON = JSON(response.result.value!)

                if let jsonArray = swiftyJSON.dictionary {

                    if let code = jsonArray["LL"]!["code"].int {

                        if(code == 200){

                            print("response code", code);

                    }

                }else{
                    print("ELSE jsonArray");
                }

                print(swiftyJSON)
            }
    }
}

Problem is with my gettoken request.
I am getting **400 => Bad Request**. I do not have any clue whats going wrong.

This is not an issue concerning the lxCommunicator-source - you're requesting support on your own project. However, without reviewing your source in detail, it appears to be a common mistake.

Unlike the getkey2 request, the gettoken request has to be encrypted. The Miniserver will decline requests for tokens that are not encrypted with code 400. We will update our documentation, to make this information more prominent.

Thanks for response. is there any code available of iOS.

[LxToubey]

No, you will have to stick to JS for now.

I have done it in iOS BTW. was too difficult to trasnlate the JS code and the lxcommunicator docs was very comprehensive too. Thanks anyways for JS code. this helped alot.
