HTTP Request library for Arduino and the WiFi shield. I modified the original Ethernet-only version to use on Intel Edison, should work fine with other Arduino WiFi devices though.

I think aJSON would be really helpful to integrate as a next step.

Clone (or download and unzip) the repository to ~/Documents/Arduino/libraries where ~/Documents/Arduino is your sketchbook directory.

> cd ~/Documents/Arduino
> mkdir libraries
> cd libraries
> git clone https://github.com/rexstjohn/arduino-restclient.git RestClient

You need to have the WiFi library already included.

#include <WiFi.h>
#include <SPI.h>
#include "RestClient.h"

Constructor to create an RestClient object to make requests against.

Use domain name and default to port 80, add your WiFi SSID and password:

RestClient client = RestClient("google.com", SSID, PW);

Sets up WiFiClient using the provided SSID and PW

  client.connect()

Note: you can have multiple RestClient objects but only need to call this once.

Note: if you have multiple Arduinos on the same network, you'll need to give each one a different mac address.

It just wraps the WiFiClient call to begin and connects.

All methods return an HTTP status code or 0 if there was an error.

Start making requests!

int statusCode = client.get("/"));

Pass in a string by reference for the response:

String response = "";
int statusCode = client.get("/", &response);

String response = "";
int statusCode = client.post("/", &response);
statusCode = client.post("/", "foo=bar");
response = "";
statusCode = client.post("/", "foo=bar", &response);

String response = "";
int statusCode = client.put("/", &response);
statusCode = client.put("/", "foo=bar");
response = "";
statusCode = client.put("/", "foo=bar", &response);

String response = "";
int statusCode = client.del("/", &response);
