ESP8266 Community Forum

Hi all
I just want to send a simple data to PHP script from my NODEMCU V1 "ESP12"
Test:
http://192.168.1.44/arduino/test.php?name=miguel&age=21

Result:
Hi miguel. You're old enough to have a drink, but do so responsibly.

It work fine from web-browser¡¡¡¡¡

If someone know a simple way to send a post please share whit me or tell me what are doing bad.
I made this sketch:


#include <ESP8266WiFi.h>
#include <ArduinoHttpClient.h>
const char* ssid = "****************";
const char* password = "******************";
char serverAddress[] = "192.168.1.44"; // server address

int port = 80;
const char* host = "http://192.168.1.44";

WiFiClient wifi;
HttpClient client = HttpClient(wifi, host, port);
int status = WL_IDLE_STATUS;


String response;
int statusCode = 0;

void setup() {
Serial.begin(115200);
delay(10);

// We start by connecting to a WiFi network

Serial.println();
Serial.println();
Serial.print("Connecting to ");
Serial.println(ssid);


/* Explicitly set the ESP8266 to be a WiFi-client, otherwise, it by default,
would try to act as both a client and an access-point and could cause
network-issues with your other WiFi-devices on your WiFi-network. */
WiFi.mode(WIFI_STA);
WiFi.begin(ssid, password);
Serial.println("Signal Strenght : " + String(WiFi.RSSI()) + " dBm");

while (WiFi.status() != WL_CONNECTED) {
delay(500);
Serial.print(".");
}

Serial.println("");
Serial.println("WiFi connected");
Serial.println("IP address: ");
Serial.println(WiFi.localIP());
}

int value = 0;

void loop() {

Serial.println("making POST request");
String contentType = "arduino/test.php";
String postData = "name=Alice&age=12";
client.post("/", contentType, postData);
// read the status code and body of the response
statusCode = client.responseStatusCode();
response = client.responseBody();

Serial.print("Status code: ");
Serial.println(statusCode);
Serial.print("Response: ");
Serial.println(response);


Serial.println("Wait five seconds");
delay(5000);

}

The printout Result is:
making POST request
Status code: -2
Response:
Wait five seconds

PHP script:

You seems to use the example from https://github.com/arduino-libraries/Ar ... lePost.ino, but you changed contentType incorrectly and didn't provide URL in the post itself.
Code should look like, as in the original example, but with you PHP URL :


BTW, there is also the ESP8266HTTPClient library :
