I am sending post request from my arduino device to my hosted server it gives me 400 Bad request error. Same code runs well in my localhost but not working on Hosted server. My arduino code if give below.
void callApi(String ID,String path,int comm,String message,int isResponseNeeded) {
String serverPath="www.xyz.com";
String data = "{" ;
data = data + "\"id\": \""+ID+"\"," ;
data = data + "\"version\": \""+VERSION+"\"," ;
data = data + "\"command\": \""+comm+"\"," ;
data = data + "\"message\": \""+message+"\"" ;
data = data + "}" ;
Serial.print("Send data...on=>");
Serial.println(path);
if (wifiClient.connect(serverPath,80)) {
Serial.println(data);
wifiClient.println("POST /abc/xyz HTTP/1.1");
wifiClient.println("Content-Type: application/json");
wifiClient.print("Host: ");
wifiClient.println(serverPath);
wifiClient.print("Content-Length: ");
wifiClient.println(data.length());
wifiClient.print("\n");
wifiClient.print(data);
wifiClient.print("\n");
Serial.println("Data sent...Reading response..");
if(isResponseNeeded>0){
unsigned long timeout = millis();
while (wifiClient.available() == 0) {
if (millis() - timeout > 10000) {
Serial.println(">>> Client Timeout !");
break;
}
}
String response;
while(wifiClient.available()){
String line = wifiClient.readStringUntil('\n');
response=line;
Serial.println(response);
}
Serial.println(response.length());
}
out put of this code.
{"id": "_60_1_94_f_a9_3c_","version": "1.10","command": "0","message": ""}
