Hi, I need your help. Should I translate this code from c # to FOXPRO. Can you help me please

//Creo la request per creare un nuovo marker
string url = "

https://ws.ar.pikkart.com/cms/markers";

HttpWebRequest webRequest = (HttpWebRequest)WebRequest.Create(url);

//Imposto il content-type
webRequest.ContentType = "text/html";

//Come metodo specifico POST, che in http indica una insert
webRequest.Method = "POST”;


string requestBody = " {"name": "my marker name", "brandId": 372, "cntId": 9725, "width":1.0, "publishedFrom":"Fri, 2 Sep 2016 GMT", "publishedFrom":"Fri, 9 Sep 2016 GMT", "imageStreamName":"myImageFileName" } ";


//Creo una stringa contenente la data e l’ora odierna in formato RFC1123, utilizzando il timezone UTC
string date = DateTime.UtcNow.ToString("R");

//Imposto l’header “Date” della richiesta
webRequest.Headers.Add("Date ", date);

//Imposto l’header “Authorization” della richiesta
webRequest.Headers.Add("Authorization", publicKey + ":" + CreateSignature(webRequest.Method, requestBody, privateKey, date, “/cms/markers”));


//Se la richiesta non ha come metodo GET, probabilmente ho un requestBody da inviare, quindi imposto lo stream della richiesta con il contenuto (requestBody) che voglio inviare
if (webRequest.Method != "GET")
{
StreamWriter streamWriter = new StreamWriter(webRequest.GetRequestStream());
streamWriter.Write(requestBody);
streamWriter.Flush();
streamWriter.Close();
}

//Invio la richiesta al server
string result = "";
HttpWebResponse httpResponse = (HttpWebResponse)webRequest.GetResponse();

//Leggo il contenuto della risposta del server
using (StreamReader streamReader = new StreamReader(httpResponse.GetResponseStream()))
result = streamReader.ReadToEnd();

//Se la risposta ha codice diverso da 200 (HttpStatusCode.OK in C#) si tratta di un errore http
if (httpResponse.StatusCode != HttpStatusCode.OK)
throw new Exception(result);

//A questo punto nella stringa result ho il contenuto della risposta, es:
{"id":8472, "name":"my marker name", "brandId":958, "cntId":1256, "cntType":1, "parentCntId":0, "crsId":"2_405", "width":1.0, "imageUrl":"

http://ar.pikkart.com/markers/sample_marker.jpg",

"publishedFrom":"2016-09-02T00:00:00Z", "publishedTo":"2016-09-09T00:00:00Z" }













public string CreateSignature(string requestMethod, string requestBody, string privateKey, string requestDate, string requestPath)
{
string contentMD5 = GetMd5Hash(requestBody);
string stringToSign = GetStringToSign(requestMethod, contentMD5, requestDate, requestPath);
byte[] sha1Bytes = Encoding.UTF8.GetBytes(stringToSign);
byte[] key = Encoding.UTF8.GetBytes(privateKey);
byte[] hashedKey = SHA1.Create().ComputeHash(key);
HMACSHA1 hmac = new HMACSHA1(hashedKey);
byte[] hashedBytes = hmac.ComputeHash(sha1Bytes);
return System.Convert.ToBase64String(hashedBytes);
}

public GetStringToSign(string requestMethod, string contentMD5, string requestDate, string requestPath)
{
return string.Format("{0}|{1}|{2}|{3}", requestMethod, contentMD5, requestDate, requestPath);
}

This question is probably more appropriate in forum184.

While the example code deals with web methids and therefore may have some relation to XML, the issue at this point is that of refactoring C# and .Net into Foxpro.
