ESP8266 GET method error I am working on ESP8266 and I want to send a GET request with AT command to my localhost but I failed every time. Can you help me solve this problem please? Thank you for interest!
I attached my terminal code and my code:


#define ag_ismi "SUPERONLINE_WiFi_8022"
#define ag_sifresi "rC5YGNYebuCf"
#define IP "192.168.1.9"

void setup() {
  // put your setup code here, to run once:

  Serial.begin(115200);
  Serial.println("AT");
  delay(3000);
  if(Serial.find("OK")){
    Serial.println("AT+CWMODE=1"); 
    delay(2000);
    String baglantiKomutu=String("AT+CWJAP=\"")+ag_ismi+"\",\""+ag_sifresi+"\"";
    Serial.println(baglantiKomutu);
    delay(5000);     
  }
}

void loop() {
  // put your main code here, to run repeatedly:
  delay(60000);
  Serial.println("AT+CIPMUX=1");
  Serial.println("AT+CIPSTART=\"TCP\",\"192.168.1.9\",8000");
  delay(1000);
  String model = "GET /kanbanDB/arduino?model=1 HTTP/1.1";
  //model+="Host: 192.168.1.9:8000\r\n\r\n";
  model+="r\n\r\n";
  Serial.println("AT+CIPSEND=" + String(model.length()));
  Serial.println("\r\n\r\n");
  delay(1000);
  Serial.println(model);
  Serial.println("\r\n\r\n");
  delay(1000);
  Serial.println(""); 
}
It should be 

String model = "GET /kanbanDB/arduino?model=1 HTTP/1.1\r\n";
model+="Host: 192.168.1.9\r\n\r\n";


remove Serial.println("\r\n\r\n"); before Serial.println(model); it is send before GET line

Serial.println("AT+CIPSTART=\"TCP\",\"192.168.1.9\",8000");
String model = "GET /kanbanDB/arduino?model=1 HTTP/1.1\r\n";
model+= "Host: 192.168.1.9\r\n\r\n";
Serial.print("AT+CIPSEND=");
Serial.println(model.length());
delay(1000);
Serial.print(model);
delay(1000);


EDIT:
Remove debug prints to Serial or use SoftwareSerial to connect the esp8266 to Uno. Now the debug prints are sent to esp8266 mixed with AT commands and data. For SoftwareSerial change the default baud rate of the AT firmware.
