Question

I’m working with JSON for a while now, but this is a problem I can’t solve.

The program is written in C# and has a method called CreateWebRequest():

public void CreateWebRequest()
    {
        CurrentTime = DateTime.Now;
        target = link;
        request = WebRequest.Create(target) as HttpWebRequest;
        request.ContentType = "application/json; charset=utf-8";
        request.Method = "PUT";
        request.ServicePoint.Expect100Continue = false;
        string postData = jsonString;
        System.Console.WriteLine("POSTDATA: " + postData);
        StreamWriter requestWriter;
        using (requestWriter = new StreamWriter(request.GetRequestStream()))
        {
            requestWriter.Write(postData);
        }

    }

The other function to fetch the result is called: CreateWebResponse():

public void CreateWebResponse()
    {
        WebResponse response;

        string text;
        try
        {
            response = (HttpWebResponse)request.GetResponse();
        }

        catch (WebException e)
        {
            MessageBox.Show(e.Message);
            return;
        }

        using (var sr = new StreamReader(response.GetResponseStream()))
        {
            text = sr.ReadToEnd();
        }

        APIresult apiresult = JsonConvert.DeserializeObject<APIresult>(text); //Deserialize the text

    }

These functions work all fine, there is only one problem: the code does two requests.

When I put the same JSON in the RESTClient in mozilla FireFox the JSON works fine. It also works great when I’m only using CreateWebRequest(), but when I use both of the methods it seems the code creats a second request?

Is it possible to create only a response? Combine these two functions to one which creates directly an response?

I tried other solutions and put them just together, none of them seems to work. When I call for a response the code doesn’t work properly anymore and creates two requests.

Has anyone a solution?

Thanks in advance.

The JSON function I call has several if statements and work fine according to RESTClient in Firefox.
The code below shows the code which is called correct by RESTClient and twice by the C# code:

$sql = 'SELECT...';
        $result = $db->sql_query($sql);//search for member id.
        if($row = $db->sql_fetchrow($result)){//when found, the user has access.
            $member_id = $row['member_id'];
            $sql = 'SELECT ...';
            $result = $db->sql_query($sql);//search for last login today.
            if($row = $db->sql_fetchrow($result)){//if the user has logged in today update the row. 
                $row_check_in_timestamp = $row['check_in_timestamp'];
                $sql = 'UPDATE ...';//update the row with the check out timestamp
                $db->sql_query($sql);
                break;
            }else{//the user hasn't logged in yet today, log in.
                $start_session_array = array(
                    'club_id'   => (int)$club_id,
                    'member_id' => (int)$member_id,
                    'check_in_timestamp' => (int)time(),
                );
                $sql = 'INSERT ...';//check user in and add a new row in the database
                $db->sql_query($sql);
                break;
            }
        }else{
            break;
        }

SOLVED: I’m sorry every one and thanks for all the responses, but I’ve found the problem. I had an older version as service running all the time and made the second JSON call.

I’ve found it by logging on the server side the calls and blocked code which call the JSON in my own code to figure this out.
