I have been trying to get a POST request on my webserver, however every time I got error 400 - bad request. I use the Arduino MKR Wifi 1010 running WiFiNINA sample code for post requests.
The URL that I would like to execute is https://XXXXXX.azurewebsites.net/measurements.php?deviceid=XXXXXX&value=XXXXXXX"
I have added the domain certificate with the WiFiNINA firmware updater, so maybe the way in which I create the query is wrong?
Would appreciate any help in this matter!
Here is the code that I try to execute:
#include <SPI.h>
#include <WiFiNINA.h>
#include "arduino_secrets.h"
///////please enter your sensitive data in the Secret tab/arduino_secrets.h
char ssid[] = SECRET_SSID; // your network SSID (name)
char pass[] = SECRET_PASS; // your network password (use for WPA, or use as key for WEP)
int deviceID = 99;
int value = 42;
char server[] = "XXXXXX.azurewebsites.net";
int status = WL_IDLE_STATUS;
WiFiSSLClient client;
void setup() {
Serial.begin(9600);
while (!Serial) {
; // wait for serial port to connect. Needed for native USB port only
}
// check for the WiFi module:
if (WiFi.status() == WL_NO_MODULE) {
Serial.println("Communication with WiFi module failed!");
// don't continue
while (true);
}
String fv = WiFi.firmwareVersion();
if (fv < WIFI_FIRMWARE_LATEST_VERSION) {
Serial.println("Please upgrade the firmware");
}
// attempt to connect to WiFi network:
while (status != WL_CONNECTED) {
Serial.print("Attempting to connect to SSID: ");
Serial.println(ssid);
// Connect to WPA/WPA2 network. Change this line if using open or WEP network:
status = WiFi.begin(ssid, pass);
// wait 10 seconds for connection:
delay(10000);
}
Serial.println("Connected to wifi");
printWiFiStatus();
Serial.println("\nStarting connection to server...");
// if you get a connection, report back via serial:
if (client.connect(server, 443)) {
Serial.println("connected to server");
// Make a HTTP request:
client.println("POST /measurements.php?deviceid=" + String(deviceID)+ "&value=" + String(value));
client.println("Host: http://XXXXXX.azurewebsites.net");
client.println("Connection: close");
client.println();
}
else{
Serial.println("Cannot connect to the server");
}
}
void loop() {
// if there are incoming bytes available
// from the server, read them and print them:
while (client.available()) {
char c = client.read();
Serial.write(c);
}
// if the server's disconnected, stop the client:
if (!client.connected()) {
Serial.println();
Serial.println("disconnecting from server.");
client.stop();
// do nothing forevermore:
while (true);
}
}
void printWiFiStatus() {
// print the SSID of the network you're attached to:
Serial.print("SSID: ");
Serial.println(WiFi.SSID());
// print your board's IP address:
IPAddress ip = WiFi.localIP();
Serial.print("IP Address: ");
Serial.println(ip);
long rssi = WiFi.RSSI();
Serial.print("signal strength (RSSI):");
Serial.print(rssi);
Serial.println(" dBm");
