Using ethernet, how do I navigate to a page on my local server

Question

I want to access the following page on my local using my Arduino with ethernet shield" 192.168.1.2/zombie/arduino.php. My arduino is conencted to a PC through a router. The system keeps timing out

I am using the following code:

#include <Ethernet.h>
#include <SPI.h>
byte mac[] = { 0xDE, 0xAD, 0xBE, 0xEF, 0xFE, 0xED };
byte ip[] = { 192,168,1,3 };
char server[] = "192.168.1.2/zombie/arduino.php";
EthernetClient client;
void setup()
{
 Ethernet.begin(mac, ip);
 Serial.begin(9600);
 delay(1000);
 Serial.println("connecting...");
 int res = client.connect(server, 80);
 Serial.println(res);
 if (res) {
 Serial.println("connected");
 client.println();
 } else {
 Serial.println("connection failed");
 }
}
void loop()
{
 if (client.available()) {
 char c = client.read();
 Serial.println("data:");
 Serial.println(c);
 }else{
 Serial.println("NA");
 }
 if (!client.connected()) {
 Serial.println();
 Serial.println("disconnecting.");
 client.stop();
 for(;;)
 ;
 }
}

• Chris Stratton: "localhost" means the loopback interface (ie, 127.0.0.1), and so by definition cannot be accessed from any other system. You have a local server (presumably on the same subnet as your Arduino), not a "localhost" one.

Answer 1

I discovered the answer after some testing.

The server var:

char server[] = "192.168.1.2/zombie/arduino.php";

should only contain the ip address. So it should look like this:

byte server[] = { 192,168,1,2 };

The additional URL elements should be added using:

client.println("GET /zombie/arduino.php");

after a connection has been established

The final code should look like this:

#include <Ethernet.h>
#include <SPI.h>
byte mac[] = { 0xDE, 0xAD, 0xBE, 0xEF, 0xFE, 0xED };
byte ip[] = { 192,168,1,3 };
byte server[] = { 192,168,1,2 };
EthernetClient client;
void setup()
{
 Ethernet.begin(mac, ip);
 Serial.begin(9600);
 delay(1000);
 Serial.println("connecting...");
 int res = client.connect(server, 80);
 Serial.println(res);
 if (res) {
 Serial.println("connected");
 client.println("GET /zombie/arduino.php");
 client.println();
 } else {
 Serial.println("connection failed");
 }
}
void loop()
{
 if (client.available()) {
 char c = client.read();
 Serial.println("data:");
 Serial.println(c);
 }else{
 Serial.println("NA");
 }
 if (!client.connected()) {
 Serial.println();
 Serial.println("disconnecting.");
 client.stop();
 for(;;)
 ;
 }
}
