I want to send some text to Apache Server, but i get some errors
I'm a newbie in ESP2866.
I can't find the reasons.
I received: "400 Bad request".......Request header field is missing ':' separator:
then i received some errors:
Wrong syntax....
I send following header to server:
POST /receiver.php HTTP/1.1
Host: 192.168.1.9
Content-Type: application/x-www-form-urlencoded
Content-Length: 20
temp=35
I use this code in Arduino:
String cmd,aaa;
aaa="temp="+35;
cmd= "POST /temp.php HTTP/1.1\r\n";
cmd+="Host: 192.168.1.9\r\n";
cmd+="Content-Type: text/plain\r\nContent-Length: "+aaa.length();
cmd+="\r\n\r\n"+aaa+"\r\n\r\n";
Serial.print("Sending to Server: ");
aaa= "AT+CIPSEND=";
aaa+=cmd.length();
aaa+="\r\n";
Serial.println(sendData(aaa, 1000));
Serial.println(sendData(cmd,2000));
delay(1000);
This is sendData function:
String sendData(String command, const int timeout)
{
String response = "";
esp.print(command); // send the read character to the esp8266
long int time = millis();
while ( (time + timeout) > millis())
{
while (esp.available())
{
// The esp has data so display its output to the serial window
char c = esp.read(); // read the next character.
response += c;
}
}
return response;
}
Rolf :
The \"Request Header Field is missing\" error is reported by the server. It looks like you are missing the \"From\" and \"User-Agent\" headers.\n\nThe \"Wrong Syntax\" error is likely generated by the ESP8266, I am currently experiencing the same problem.",
