I get an error in GetRequestStream:
if (Program.ethernet.IsNetworkUp)
{
HttpWebRequest request = (HttpWebRequest)HttpWebRequest.Create(@ "http://localhost/Smarthouse/Process/Microcontroler.php");
request.Method = "POST";
request.ContentType = "application/json";
request.ContentLength = 100;
Stream s = request.GetRequestStream();
s.Write(BitConverter.GetBytes("{\"data1\": \"test\"}"));
s.Close();
WebResponse response = request.GetResponse();
var he = response.Headers;
}
My error is:
#### Exception System.Net.Sockets.SocketException - CLR_E_FAIL (8) ####
#### Message:
#### Microsoft.SPOT.Net.SocketNative::connect [IP: 0000] ####

My php page returns “Yes” and it is working (entering url into web browser). The server is apache.
Why are you setting ContentLength to some constant and not to the actual length of the data. This can be the reason.
Try this:
if (Program.ethernet.IsNetworkUp)
{
HttpWebRequest request = (HttpWebRequest)HttpWebRequest.Create(@ "http://localhost/Smarthouse/Process/Microcontroler.php");
request.Method = "POST";
request.ContentType = "application/json";
byte[] postData = BitConverter.GetBytes("{\"data1\": \"test\"}");
request.ContentLength = postData.Length;
Stream s = request.GetRequestStream();
s.Write(postData);
s.Close();
WebResponse response = request.GetResponse();
var he = response.Headers;
}

Thanks, but no.
public partial class Program
{
void ProgramStarted()
{
Debug.Print("Program Started");
if (!ethernet_J11D.Interface.IsOpen)
ethernet_J11D.Interface.Open();
NetworkInterfaceExtension.AssignNetworkingStackTo(ethernet_J11D.Interface);
ethernet_J11D.NetworkUp += new GTM.Module.NetworkModule.NetworkEventHandler(ethernet_J11D_NetworkUp);
ethernet_J11D.UseDHCP();
}
void ethernet_J11D_NetworkUp(GTM.Module.NetworkModule sender, GTM.Module.NetworkModule.NetworkState state)
{
HttpWebRequest request = (HttpWebRequest)HttpWebRequest.Create(@ "http://localhost/Smarthouse/Process/Microcontroler.php");
request.Method = "POST";
request.ContentType = "application/json";
byte[] postData = BitConverter.GetBytes("{\"data1\": \"test\"}");
request.ContentLength = postData.Length;
Stream s = request.GetRequestStream();
s.Write(postData);
s.Close();
WebResponse response = request.GetResponse();
var he = response.Headers;
}
void request_ResponseReceived(HttpRequest sender, HttpResponse response)
{
if (response.StatusCode == "202")
{
}
}
}

See if changing KeepAlive or Timeout on the request object makes any difference.

Sorry, nothing:

Localhost sweet localhost.
Try real ip of your server

Lame, lame, lame, lame.
By the way. It is also not working on 127.0.0.1. But it perfectly works on some domain.
@ Makla -
localhost is the “standard” name for ip address 127.0.0.1. You can name it differently too. Check:
Windows\System32\Drivers\etc\hosts
