Sending data to php website

Hi there!

I'm currently trying to send data from the netduino plus to my webserver via a special php site. When I call the site manually from my webbrowser everything works fine. But when doing the same via code from the netduino it does not work.

Here's the sending code (inspired by these forums):

private void SendHttpRequest(string serverUrl, string request){  IPHostEntry host = Dns.GetHostEntry(serverUrl);  IPEndPoint endPoint = new IPEndPoint(host.AddressList[0], 80);  using (Socket socket = new Socket(AddressFamily.InterNetwork, SocketType.Stream, ProtocolType.Tcp))  {    socket.Connect(endPoint);    using (NetworkStream ns = new NetworkStream(socket))    {      byte[] bytes = System.Text.Encoding.UTF8.GetBytes("GET " + request + " HTTP/1.1rn");      ns.Write(bytes, 0, bytes.Length);    }  }}

And this is how I call it:

SendHttpRequest("www.mywebsite.com", "/netduino/submitData.php?data=5");

The problem is, that the php script on the website is never called. So I guess there is something wrong with the way I send the HTTP request?

Thanks for your help!

Is this PHP script hosted on a shared webserver (i.e. cheap hosting account)?  If so then it will be setup using HostNames for multiple site support from a single IP.  As you are connecting directly to the server by IP you need to specify the hostname for your site as a HTTP header.

If on the other hand the script is hosted locally, try just specifying the IP address of the server and check that you can access your site just by its IP.  As unless the IP is bound to port 80 as well as a host name your server wont respond.

Finally check that the name is being resolved correctly by the Dns call, sometimes i have found the ND to need the DNS server to be specified manually as it wasnt for some reason being assigned by DHCP.

I would also try and use the HttpClient in the netmf toolbox, https://netmftoolbox...ailable classes as it works very well and lets you post data easily as well...

You could also look at the source for inspiration as well.

Allright, got it working 

I ended up including the System.Http assembly, which makes everything nice and easy. And it adds only 30kB to the final application size.

VanKurt,

You were trying to send data to your php website, and you got it working with System.Http. Can you please post the code for the Netduino and also the php code.

Thanks,

Mark
