I'm new with the Arduino platform so please be gentle. I purchased and Arduino Uno and Wishield 2. I've successfully compiled and run the SimpleClient app, displaying the returned results in the serial monitor window. Now I'm trying to modify that app to hit a page that requires authentication. I've looked through the docs on WiShield involving char auth but I don't understand how to send that authentication.
My app:
- Code: Select all
/*
* A simple sketch that uses WiServer to get the hourly weather data from LAX and prints
* it via the Serial API
*/
#include <WiServer.h>
#define WIRELESS_MODE_INFRA 1
#define WIRELESS_MODE_ADHOC 2
// Wireless configuration parameters ----------------------------------------
unsigned char local_ip[] = {192,168,1,2}; // IP address of WiShield
unsigned char gateway_ip[] = {192,168,1,1}; // router or gateway IP address
unsigned char subnet_mask[] = {255,255,255,0}; // subnet mask for the local network
const prog_char ssid[] PROGMEM = {"Network"}; // max 32 bytes
unsigned char security_type = 3; // 0 - open; 1 - WEP; 2 - WPA; 3 - WPA2
// WPA/WPA2 passphrase
const prog_char security_passphrase[] PROGMEM = {"12345678"}; // max 64 characters
// WEP 128-bit keys
// sample HEX keys
prog_uchar wep_keys[] PROGMEM = { 0x01, 0x02, 0x03, 0x04, 0x05, 0x06, 0x07, 0x08, 0x09, 0x0a, 0x0b, 0x0c, 0x0d, // Key 0
0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, // Key 1
0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, // Key 2
0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00 // Key 3
};
// setup the wireless mode
// infrastructure - connect to AP
// adhoc - connect to another WiFi device
unsigned char wireless_mode = WIRELESS_MODE_INFRA;
unsigned char ssid_len;
unsigned char security_passphrase_len;
// End of wireless configuration parameters ----------------------------------------
// Function that prints data from the server
void printData(char* data, int len) {
// Print the data returned by the server
// Note that the data is not null-terminated, may be broken up into smaller packets, and
// includes the HTTP header.
while (len-- > 0) {
Serial.print(*(data++));
}
}
// IP Address for the site I want to hit
uint8 ip[] = {11,11,11,11};
// Base64 encoded USERNAME:PASSWORD
char auth[] = "AOj5OmfYaWvz";
// A request that gets the data I want
GETrequest getPublicProd(ip, 80, "http://mysite.com", "/data.txt");
void setup() {
// Initialize WiServer (we'll pass NULL for the page serving function since we don't need to serve web pages)
WiServer.init(NULL);
// Enable Serial output and ask WiServer to generate log messages (optional)
Serial.begin(57600);
WiServer.enableVerboseMode(true);
// Have the processData function called when data is returned by the server
getPublicProd.setReturnFunc(printData);
}
// Time (in millis) when the data should be retrieved
long updateTime = 0;
void loop(){
// Check if it's time to get an update
if (millis() >= updateTime) {
getPublicProd.submit();
// Get another update one hour from now
updateTime += 1000 * 60 * 60;
}
// Run WiServer
WiServer.server_task();
delay(10);
}
The result I get in the serial monitor is a 400 error from the webserver. I'm assuming that is because it's not authenticating. (IP addresses, user/pass, and site name changed to protect the innocent.)

It should returen a simple line of text along with the header info. Can someone please point me the way? I've been searching the forums and have found no examples that help explain this issue to me.
thanks!
