i want to send a string via a web page HTML. I write my code, i know its wrong but if you have any ideas would be helpful.
thank you very much!!
#include <SPI.h>
#include <Client.h>
#include <Ethernet.h>
#include <Server.h>
#include <Udp.h>
#include <String/WString.h>
// Enter a MAC address and IP address for your controller below.
// The IP address will be dependent on your local network:
byte mac[] = { 0xDE, 0xAD, 0xBE, 0xEF, 0xFE, 0xED };
IPAddress ip(192,168,1, 35); // ip del rango establecido en el router
char producto[24];
byte contador=0;
// Initialize the Ethernet server library
// with the IP address and port you want to use
// (port 80 is default for HTTP):
EthernetServer server(80);
String readString = String(30);
void setup()
{
// start the Ethernet connection and the server:
Ethernet.begin(mac, ip);
server.begin();
Serial.begin(9600);
}
void loop()
{
// listen for incoming clients
EthernetClient client = server.available();
if (client) {
// an http request ends with a blank line
boolean currentLineIsBlank = true;
while (client.connected()) {
if (client.available()) {
char c = client.read();
if (readString.length()<30) //leer peticion HTTP caracter por caracter
{
readString += c;
}
if (c=='\n') //Si la peticion HTTP ha finalizado
{
}
}//while
Serial.print(producto);
readString=""; //Vaciar el string que se uso para la lectura
//Enviar cabecera HTTP estandar
client.println("HTTP/1.1 200 OK");
client.println("Content-Type: text/html");
client.println();
//Crear pagina web HTML
client.println("<html>");
client.println("<head>");
client.println("<title>Centro de control de productos</title>");
client.println("</head>");
client.println("<body>");
client.println("<h1>Centro de control de productos</h1>");
client.println("
<hr>
");
client.println("<b>Nombre del Producto");
client.println("
<form method=get enctype=text/plain> <input type=text name=nombreproducto size=25 maxlength=50>
");
client.println("<hr><input type=submit name=Aceptar value=Introducir><input type=Reset name=Cancelar value=Cancelar></form>");
client.println("<hr>
");
client.println("</body>");
client.println("</html>");
client.stop();
}
}
}
I have not yet programmed, i have only the website programmed, but I think I should set it here to copy the string
if (client) {
// an http request ends with a blank line
boolean currentLineIsBlank = true;
while (client.connected()) {
if (client.available()) {
char c = client.read();
if (readString.length()<30) //leer peticion HTTP caracter por caracter
{
readString += c;
}
if (c=='\n') //Si la peticion HTTP ha finalizado
{
}
}//while
Sorry but i am from Spain and I do not write very well in English.
thanks
Server test code that uses a form text box to make a GET request. You can view what the server is receiving by using the serial monitor.
//zoomkat 12-08-12
//get submit box code
//for use with IDE 1.0
//open serial monitor to see what the arduino receives
//use the \ slash to escape the " in the html or use a '
//address will look like http://192.168.1.102:84 when submited
//for use with W5100 based ethernet shields
//note that the below bug fix may be required
// http://code.google.com/p/arduino/issues/detail?id=605

byte gateway[] = { 192, 168, 1, 1 }; // internet access via router

I think this is very interesting because i want a string to send and i have not found any example.
Thank you very much

I have tried but i have many problems, i want to keep "nombredeproducto" to my arduino via a website HTML
Language might be one of them, because this statement makes no sense. You can't send a webpage to the Arduino. The Arduino can serve up a page. If the page contains a form, with a submit button, and an action field, that action field can cause another GET request to be made. If the form also contains text fields, the contents of those fields will be part of the GET request. You can then parse the GET request, to see if it contains anything for you to deal with, as opposed to an initial request for the page.
