Supported features

The following commands are supported as of now.

GET

Obviously this is an input binding and can be used like this.

[FunctionName("MyInputSample")]
public static void MyInputSample(
	[HttpTrigger(AuthorizationLevel.Anonymous, "get", Route = "MyInputSample")]
	HttpRequestMessage req,
	[Http(Url = "%BaseAddress%api/Echo/{Identifier}")] 
	HttpModel httpModel,
	ILogger log)
{
	log.LogInformation($"Executing MyInputSample function.");
	// Over here you can do something with the HttpModel.
	log.LogInformation($"Executed MyInputSample function.");
}

The HttpModel consists of both the response (Content) of the request as well as the StatusCode.

public class HttpModel
{
	public string Response { get; set; }
	public int ResponseCode { get; set; }
}

POST

An output binding which will invoke a HTTP POST to the specified URL with an object.

[FunctionName("MyOutputPostSample")]
public static void MyOutputPostSample(
	[HttpTrigger(AuthorizationLevel.Anonymous, "get", Route = "MyInputSample")]
	HttpRequestMessage req,
	[HttpCommand(CommandUrl = "%BaseAddress%api/EchoCommand", MediaType = "application/json", HttpMethod = "POST")]
	IAsyncCollector<HttpCommand> httpPostCommandCollector,
	ILogger log)
{
	var identifier = Guid.NewGuid();
	log.LogInformation($"Executing MyOutputPostSample function.");

	var model = new ModelToSend
	{
		Identifier = identifier.ToString("D")
	};
	httpPostCommandCollector.AddAsync(new HttpCommand(JsonConvert.SerializeObject(model)));

	log.LogInformation($"Executed MyOutputPostSample function.");
}

PUT

An output binding which will invoke a HTTP PUT to the specified URL with an object.

[FunctionName("MyOutputPutSample")]
public static void MyOutputPutSample(
	[HttpTrigger(AuthorizationLevel.Anonymous, "get", Route = "MyInputSample")]
	HttpRequestMessage req,
	[HttpCommand(CommandUrl = "%BaseAddress%api/EchoCommand", MediaType = "application/json", HttpMethod = "POST")]
	IAsyncCollector<HttpCommand> httpPostCommandCollector,
	ILogger log)
{
	var identifier = Guid.NewGuid();
	log.LogInformation($"Executing MyOutputPutSample function.");

	var model = new ModelToSend
	{
		Identifier = identifier.ToString("D")
	};
	httpPostCommandCollector.AddAsync(new HttpCommand(JsonConvert.SerializeObject(model)));

	log.LogInformation($"Executed MyOutputPutSample function.");
}
