Types

type HTTPClientFactory

type HTTPClientFactory func(ctx context.Context) *http.Client

HTTPClientFactory creates http clients based with the received context

type HTTPRequestExecutor

type HTTPRequestExecutor func(ctx context.Context, req *http.Request) (*http.Response, error)

HTTPRequestExecutor defines the interface of the request executor for the HTTP transport protocol

func DefaultHTTPRequestExecutor

func DefaultHTTPRequestExecutor(clientFactory HTTPClientFactory) HTTPRequestExecutor

DefaultHTTPRequestExecutor creates a HTTPRequestExecutor with the received HTTPClientFactory

type HTTPResponseError

type HTTPResponseError struct {
	Code int    `json:"http_status_code"`
	Msg  string `json:"http_body,omitempty"`
	// contains filtered or unexported fields
}

HTTPResponseError is the error to be returned by the DetailedHTTPStatusHandler

func (r HTTPResponseError) Error() string

Error returns the error message

func (HTTPResponseError) Name

func (r HTTPResponseError) Name() string

Name returns the name of the error

func (HTTPResponseError) StatusCode

func (r HTTPResponseError) StatusCode() int

StatusCode returns the status code returned by the backend

type HTTPStatusHandler

type HTTPStatusHandler func(context.Context, *http.Response) (*http.Response, error)

HTTPStatusHandler defines how we tread the http response code

func DetailedHTTPStatusHandler

func DetailedHTTPStatusHandler(next HTTPStatusHandler, name string) HTTPStatusHandler

DetailedHTTPStatusHandler is a HTTPStatusHandler implementation

func GetHTTPStatusHandler

func GetHTTPStatusHandler(remote *config.Backend) HTTPStatusHandler
