I'm trying to create a REST server on an arduino mkr1000. upon searching google i came upon the aRest library which handles most of the stuff i need.
So i created a sample sketch based on the guides. Here is the code:
#include < SPI.h >
#include < WiFi101.h >
#include < aREST.h >
aREST rest = aREST();
int status = WL_IDLE_STATUS;
WiFiServer restServer(80);
char ssid[] = "user"; // not actual username
char pass[] = "pass"; // not actual password
int clapMode(String data){
Serial.println("Request Recieved: " + data);
}
void setup() {
Serial.begin(115200);
rest.set_id("000");
rest.set_name("MKR1000");
rest.function("test",clapMode);
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();
// you're connected now, so print out the status:
printWifiStatus();
// Start server
restServer.begin();
Serial.println(F("Listening for connections..."));
}
void loop() {
WiFiClient client = restServer.available();
if (!client) {
return;
}
while(!client.available()){
delay(1);
}
rest.handle(client);
}
void printWifiStatus() {
// print the SSID of the network you're attached to:
Serial.print("SSID: ");
Serial.println(WiFi.SSID());
// print your WiFi shield's IP address:
IPAddress ip = WiFi.localIP();
Serial.print("IP Address: ");
Serial.println(ip);
IPAddress subnet = WiFi.subnetMask();
Serial.print("Netmask: ");
Serial.println(subnet);
IPAddress gateway = WiFi.gatewayIP();
Serial.print("Gateway: ");
Serial.println(gateway);
// print the received signal strength:
long rssi = WiFi.RSSI();
Serial.print("signal strength (RSSI):");
Serial.print(rssi);
Serial.println(" dBm");
}
The code works mostly. Upon using POSTMAN to perform a GET the arduino is able to give the appropriate response.
Now for the part that is not working is the endpoint i just have created using this code
rest.function("test",clapMode);
upon performing a GET in postman, the arduino is able to give a response, but it should perform this code
int clapMode(String data){
Serial.println("Request Recieved: " + data);
}
but on my serial Monitor i am not getting anything.
Also i could not find on how to tailor the response of the arduino from the request. How do i it ?
Thank you very much
