I have an ESP8266, which I'm programming in Arduino. I need make a POST request. I tried this code:
#include <ESP8266HTTPClient.h>
#include <ESP8266WiFi.h>
void setup() {
Serial.begin(115200); //Serial connection
WiFi.begin("ssid", "wifi_password"); //WiFi connection
while (WiFi.status() != WL_CONNECTED) { //Wait for the WiFI connection completion
delay(500);
Serial.println("Waiting for connection");
}
}
void loop() {
if(WiFi.status()== WL_CONNECTED){ //Check WiFi connection status
HTTPClient http; //Declare object of class HTTPClient
http.begin("server_name"); //Specify request destination
http.header("POST / HTTP/1.1");
http.header("Host: server_name");
http.header("Accept: */*");
http.header("Content-Type: application/x-www-form-urlencoded");
int httpCode = http.POST("Message from ESP8266"); //Send the request
String payload = http.getString();
Serial.println(httpCode); //Print HTTP return code
Serial.println(payload); //Print request response payload
http.end(); //Close connection
}else{
Serial.println("Error in WiFi connection");
}
delay(5000); //Send a request every 30 seconds
}
But on the web page I did not receive any response.
I found this code and it works!
Thank you very much for your help.
