This is exactly what I'm using:
#include <SPI.h>
#include <Ethernet.h>
byte mac[] = {
0xDE, 0xAD, 0xBE, 0xEF, 0xFE, 0xED
};
// Tentativa frustada, possui o mesmo problema:
//uint32_t i;
//uint8_t* TotalRequisicao;
///////////////////////////////////////////////
int i;
char* TotalRequisicao;
IPAddress ip(192, 166, 0, 23);
EthernetServer server(80);
void setup(){
Serial.begin(9600);
Ethernet.begin(mac, ip);
server.begin();
Serial.print("IP: ");
Serial.println(Ethernet.localIP());
}
void loop(){
EthernetClient client = server.available();
if(client){
while(client.connected()){
Serial.println("Novo cliente!");
i = 0;
TotalRequisicao = "";
while(char LerRequisicao = client.read()){
if(LerRequisicao == '\n'){
Serial.println();
Serial.println(TotalRequisicao);
break;
}else{
TotalRequisicao[i] = LerRequisicao;
i++;
}
}
client.println();
client.println("HTTP/1.1 200 OK");
client.println("Content-Type: text/html");
client.println("Connection: close");
client.println();
client.println("<!DOCTYPE HTML>");
client.println("<html>");
client.println("<head>");
client.println("</head>");
client.println("</html>");
break;
}
delay(1);
client.stop();
}
}
Results:
This is what is happening by running some requests for the IP.
In Arduino's Serial Monitor:
IP: 192.166.0.23
Novo cliente!
GET / HTTP/1.1
nte!GET / HTTP/1.1
nte!
GET / HTTP/1.1
nte!HTTP/1.1
nte!
GET / HTTP/1.1
nte!
In response to the request:
GET / HTTP/1.1nte!HTTP/1.1 200 OK
GET / HTTP/1.1nte!Content-Type: text/html
GET / HTTP/1.1nte!Connection: close
GET / HTTP/1.1nte!
GET / HTTP/1.1nte!<!DOCTYPE HTML>
GET / HTTP/1.1nte!<html>
GET / HTTP/1.1nte!<head>
GET / HTTP/1.1nte!</head>
GET / HTTP/1.1nte!</html>
GET / HTTP/1.1nte!
Expected responses:
This was what I would have wanted, understand the purpose of the above code:
In Arduino's Serial Monitor:
GET / HTTP/1.1
In response to the request:
HTTP/1.1 200 OK
Content-Type: text/html
Connection: close
<!DOCTYPE HTML>
<html>
<head>
</head>
</html>
I'm using the Ethernet Shield V1 and also test with W5100 module in an Arduino UNO, both have gone bad. However, the problem is being caused by char* TotalRequisicao , since by making it a comment //TotalRequisicao[i] = LerRequisicao; the problem is not displayed, but the goal is not reached either. :
My idea with TotalRequisicao[i] = LerRequisicao; would be to fully get GET / HTTP/1.1 in a single string (a char* ), thus making it easier to identify which page / file was called.
But for some reason the information of TotalRequisição has some "collision" and spread to other places where the variable was never even called.
PS: Even removing Serial.println(TotalRequisicao); , but keeping TotalRequisicao[i] = LerRequisicao; the problem persists.
What would be the reason for this and how can it be fixed?
