Hi all,
I need to let arduino UNO connect via ethernet to a web page with authentication.
I tried to use the EthernetClient library with the base authentication, but i received the error:
connecting...
http://192.168.1.181/SystemLog.htm
QWRtaW46MDEyMzQ1
connected
HTTP/1.1 401 Unauthorized
WWW-Authenticate: Basic realm="Protected"
Connection: close
401 Unauthorized: Password required
disconnecting.
Can you give me some advice? Here is my sketch:
thank you
#include <SPI.h>
#include <Ethernet.h>
byte mac[] = { 0xDE, 0xAD, 0xBE, 0xEF, 0xFE, 0xED };
IPAddress server(192,168,1,181);
IPAddress ip(192,168,1,255);
EthernetClient client;
void setup() {
Serial.begin(9600);
while (!Serial) {
; // wait for serial port to connect. Needed for Leonardo only
}
// start the Ethernet connection:
if (Ethernet.begin(mac) == 0) {
Serial.println("Failed to configure Ethernet using DHCP");
// no point in carrying on, so do nothing forevermore:
// try to congifure using IP address instead of DHCP:
Ethernet.begin(mac, ip);
}
// give the Ethernet shield a second to initialize:
delay(1000);
Serial.println("connecting...");
Serial.println("http://192.168.1.181/SystemLog.htm");
Serial.println("QWRtaW46MDEyMzQ1");
// if you get a connection, report back via serial:
if (client.connect(server, 80)) {
Serial.println("connected");
// Make a HTTP request:
//client.println("GET /search?q=arduino HTTP/1.1");
client.println("POST /SystemLog.htm");
client.println("Host: 192.168.1.181");
client.println("Authorization: Basic QWRtaW46MDEyMzQ1");
client.println("Connection: close");
client.println();
}
else {
// kf you didn't get a connection to the server:
Serial.println("connection failed");
}
}
void loop()
{
// if there are incoming bytes available
// from the server, read them and print them:
if (client.available()) {
char c = client.read();
Serial.print(c);
}
// if the server's disconnected, stop the client:
if (!client.connected()) {
Serial.println();
Serial.println("disconnecting.");
client.stop();
// do nothing forevermore:
while(true);
}
}
