Hi,
I have a problem with HttpWebRequest. I’m trying to get JSON data from local network server but I’ve get only partial of data (usually first 1069-1070 bytes).

I’m using FezPortal for that projec, and my GET is implemented as below

        private byte[] GetResult = new byte[4 * 1024];

        public string Get(string url)
        {
            int read = 0, total = 0;
            byte[] result = GetResult;

            try
            {
                HttpWebRequest.Create(url);
                using (var req = HttpWebRequest.Create(url) as HttpWebRequest)
                {
                    req.KeepAlive = true;
                    req.ReadWriteTimeout = 10000;
                    req.Timeout = 10000;

                    Thread.Sleep(500);

                    using (var res = req.GetResponse() as HttpWebResponse)
                    {
                        using (var stream = res.GetResponseStream())
                        {
                            do
                            {
                                Thread.Sleep(500);
                                read = stream.Read(result, total, result.Length-total);
                                total += read;
                            }
                            while (read != 0);
                        }
                    }

                    String page = "";

                    page = new String(System.Text.Encoding.UTF8.GetChars(result, 0, total));

                    return page;
                }
            }
            catch (Exception e)
            {
            }
            return null;
        }
    }

Is it https? If so you need set system time correctly.

No it is http - as I write some data is received, first ~1069 bytes and thats all. Same url I can fetch at web browser and also on ESP32.

4

Even using TCP socket give same behaviour (TCP connect to 80, then send GET command and in response only partial data is received - mostly HTTP Reply Header - around 1k).
Any help, advice?

I found the issue, in fact there were no issue, everything was working fine, the problem is that debugger get only a biginning from long strings, so in Visual only part of data is visible.
