Authorization (auth) package

This package allows to connect via OAuth2.0 to the arduino.cc system (Hydra)

See test package for an example of usage.

Basic usage

// Just create a new auth object.
authObj := auth.New()
token, err := auth.Token(testUser, testPass)
if err != nil {
	// Handle error
}

// Then use the generated token in your requests, for example:
// Obtain info of my user.
req, err := http.NewRequest("GET", "https://auth.arduino.cc/v1/users/byID/me", nil)
if err != nil {
	// Handle error
}
req.Header.Add("Authorization", "Bearer "+token.Access)
client := http.Client{}
resp, err := client.Do(req)
if err != nil {
	// Handle error
}

// Before your token expires, you can do a refresh to have a new one for the
// same session:
newToken, err := auth.Refresh(token.Access)
if err != nil {
	// Handle error
}
