RestClient for the Spark Core

HTTP Request library for the Spark Core. A lightly adjusted version of the RestClient for Arduino from Chris Continanza available here: https://github.com/csquared/arduino-restclient

Install

Add the files rest_client.cpp and rest_client.h to your app somehow... I just cut and paste into the Spark.io Web IDE.

Usage

RestClient(host/ip, [port])

Constructor to create an RestClient object to make requests against.

Use domain name and default to port 80:

RestClient client = RestClient("www.some-http-server.com");

Use a local IP and an explicit port:

RestClient client = RestClient("192.168.1.50",5000);

RESTful methods

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

get(const char* path)

get(const char* path, String* response)

Start making requests!

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

Pass in a string by reference for the response:

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

post(const char* path, const char* body)

post(const char* path, String* response)

post(const char* path, const char* body, String* response)

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

put(const char* path, const char* body)

put(const char* path, String* response)

put(const char* path, const char* body, String* response)

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

del(const char* path)

del(const char* path, const char* body)

del(const char* path, String* response)

del(const char* path, const char* body, String* response)

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

Full Example

I test every way of calling the library (against a public heroku app)[https://github.com/csquared/arduino-http-test].

You can find the file in File->Examples->RestClient->full_test_suite

Debug Mode

If you're having trouble, you can always open RestClient.cpp and throw at the top:

#define HTTP_DEBUG

Everything happening in the client will get printed to the Serial port.

Thanks/Credit

So far, I have just made a few minor adjustments to the excellent work of Chris Continanza, available here: https://github.com/csquared/arduino-restclient. Thanks, Chris!
