Types ¶
type BadRequestError ¶
type BadRequestError struct {
Err error
}
BadRequestError is an error in decoding the request.
func (BadRequestError) Error ¶
func (err BadRequestError) Error() string
Error implements the error interface.
type Client ¶
type Client struct {
// contains filtered or unexported fields
}
Client wraps a URL and provides a method that implements endpoint.Endpoint.
func NewClient ¶
func NewClient( method string, tgt *url.URL, enc EncodeRequestFunc, dec DecodeResponseFunc, options ...ClientOption, ) *Client
NewClient constructs a usable Client for a single remote endpoint.
type ClientOption ¶
type ClientOption func(*Client)
ClientOption sets an optional parameter for clients.
func SetBufferedStream ¶
func SetBufferedStream(buffered bool) ClientOption
SetBufferedStream sets whether the Response.Body is left open, allowing it to be read from later. Useful for transporting a file as a buffered stream.
func SetClient ¶
func SetClient(client *http.Client) ClientOption
SetClient sets the underlying HTTP client used for requests. By default, http.DefaultClient is used.
func SetClientBefore ¶
func SetClientBefore(before ...RequestFunc) ClientOption
SetClientBefore sets the RequestFuncs that are applied to the outgoing HTTP request before it's invoked.
type DecodeRequestFunc ¶
DecodeRequestFunc extracts a user-domain request object from an HTTP request object. It's designed to be used in HTTP servers, for server-side endpoints. One straightforward DecodeRequestFunc could be something that JSON decodes from the request body to the concrete response type.
type DecodeResponseFunc ¶
DecodeResponseFunc extracts a user-domain response object from an HTTP response object. It's designed to be used in HTTP clients, for client-side endpoints. One straightforward DecodeResponseFunc could be something that JSON decodes from the response body to the concrete response type.
type EncodeRequestFunc ¶
EncodeRequestFunc encodes the passed request object into the HTTP request object. It's designed to be used in HTTP clients, for client-side endpoints. One straightforward EncodeRequestFunc could something that JSON encodes the object directly to the request body.
type EncodeResponseFunc ¶
type EncodeResponseFunc func(http.ResponseWriter, interface{}) error
EncodeResponseFunc encodes the passed response object to the HTTP response writer. It's designed to be used in HTTP servers, for server-side endpoints. One straightforward EncodeResponseFunc could be something that JSON encodes the object directly to the response body.
type RequestFunc ¶
RequestFunc may take information from an HTTP request and put it into a request context. In Servers, BeforeFuncs are executed prior to invoking the endpoint. In Clients, BeforeFuncs are executed after creating the request but prior to invoking the HTTP client.
func SetRequestHeader ¶
func SetRequestHeader(key, val string) RequestFunc
SetRequestHeader returns a RequestFunc that sets the specified header.
type ResponseFunc ¶
type ResponseFunc func(context.Context, http.ResponseWriter)
ResponseFunc may take information from a request context and use it to manipulate a ResponseWriter. ResponseFuncs are only executed in servers, after invoking the endpoint but prior to writing a response.
func SetContentType ¶
func SetContentType(contentType string) ResponseFunc
SetContentType returns a ResponseFunc that sets the Content-Type header to the provided value.
func SetResponseHeader ¶
func SetResponseHeader(key, val string) ResponseFunc
SetResponseHeader returns a ResponseFunc that sets the specified header.
type Server ¶
type Server struct {
// contains filtered or unexported fields
}
Server wraps an endpoint and implements http.Handler.
func NewServer ¶
func NewServer( ctx context.Context, e endpoint.Endpoint, dec DecodeRequestFunc, enc EncodeResponseFunc, options ...ServerOption, ) *Server
NewServer constructs a new server, which implements http.Server and wraps the provided endpoint.
type ServerOption ¶
type ServerOption func(*Server)
ServerOption sets an optional parameter for servers.
func ServerAfter ¶
func ServerAfter(after ...ResponseFunc) ServerOption
ServerAfter functions are executed on the HTTP response writer after the endpoint is invoked, but before anything is written to the client.
func ServerBefore ¶
func ServerBefore(before ...RequestFunc) ServerOption
ServerBefore functions are executed on the HTTP request object before the request is decoded.
func ServerErrorEncoder ¶
func ServerErrorEncoder(f func(w http.ResponseWriter, err error)) ServerOption
ServerErrorEncoder is used to encode errors to the http.ResponseWriter whenever they're encountered in the processing of a request. Clients can use this to provide custom error formatting and response codes. By default, errors will be written as plain text with an appropriate, if generic, status code.
func ServerErrorLogger ¶
func ServerErrorLogger(logger log.Logger) ServerOption
ServerErrorLogger is used to log non-terminal errors. By default, no errors are logged.
