}

Config is a configuration struct for an HTTP client.

func NewConfig

func NewConfig() Config

NewConfig creates a new Config with default values.

type Type

type Type struct {
	// contains filtered or unexported fields
}

Type is an output type that pushes messages to Type.

func New

func New(conf Config, opts ...func(*Type)) (*Type, error)

New creates a new Type.

func (*Type) CreateRequest

func (h *Type) CreateRequest(msg types.Message) (req *http.Request, err error)

CreateRequest creates an HTTP request out of a single message.

func (*Type) Do

func (h *Type) Do(msg types.Message) (res *http.Response, err error)

Do attempts to create and perform an HTTP request from a message payload. This attempt may include retries, and if all retries fail an error is returned.

func (*Type) ParseResponse

func (h *Type) ParseResponse(res *http.Response) (resMsg types.Message, err error)

ParseResponse attempts to parse an HTTP response into a 2D slice of bytes.

func (*Type) Send

func (h *Type) Send(msg types.Message) (types.Message, error)

Send attempts to send a message to an HTTP server, this attempt may include retries, and if all retries fail an error is returned. The message payload can be nil, in which case an empty body is sent. The response will be parsed back into a message, meaning mulitpart content handling is done for you.

If the response body is empty the message returned is nil.
