Overview

Package echo implements a fast and unfancy micro web framework for Go.

Example: 

package main

import (
    "net/http"

    echo "gopkg.in/labstack/echo.v1"
    mw "gopkg.in/labstack/echo.v1/middleware"
)

func hello(c *echo.Context) error {
    return c.String(http.StatusOK, "Hello, World!\n")
}

func main() {
    e := echo.New()

    e.Use(mw.Logger())
    e.Use(mw.Recover())

    e.Get("/", hello)

    e.Run(":1323")
}

type Renderer added in v0.0.7 

type Renderer interface {
	Render(w io.Writer, name string, data interface{}) error
}

Renderer is the interface that wraps the Render method.

type Response added in v0.0.13 

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

Response wraps an http.ResponseWriter and implements its interface to be used by an HTTP handler to construct an HTTP response. See http.ResponseWriter(https://golang.org/pkg/net/http/#ResponseWriter)

func NewResponse added in v0.0.14 

func NewResponse(w http.ResponseWriter, e *Echo) *Response

NewResponse creates a new instance of Response.

func (*Response) CloseNotify added in v0.0.13 

func (r *Response) CloseNotify() <-chan bool

CloseNotify implements the http.CloseNotifier interface to allow detecting when the underlying connection has gone away. This mechanism can be used to cancel long operations on the server if the client has disconnected before the response is ready. See http.CloseNotifier(https://golang.org/pkg/net/http/#CloseNotifier)

func (*Response) Committed added in v1.2.0 

func (r *Response) Committed() bool

Committed asserts whether or not the response has been committed to.

func (*Response) Flush added in v0.0.13 

func (r *Response) Flush()

Flush implements the http.Flusher interface to allow an HTTP handler to flush buffered data to the client. See http.Flusher(https://golang.org/pkg/net/http/#Flusher)

func (*Response) Header added in v0.0.13 

func (r *Response) Header() http.Header

Header returns the header map for the writer that will be sent by WriteHeader. Changing the header after a call to WriteHeader (or Write) has no effect unless the modified headers were declared as trailers by setting the "Trailer" header before the call to WriteHeader (see example) To suppress implicit response headers, set their value to nil. Example [ResponseWriter.Trailers](https://golang.org/pkg/net/http/#example_ResponseWriter_trailers)

func (*Response) Hijack added in v0.0.13 

func (r *Response) Hijack() (net.Conn, *bufio.ReadWriter, error)

Hijack implements the http.Hijacker interface to allow an HTTP handler to take over the connection. See http.Hijacker(https://golang.org/pkg/net/http/#Hijacker)

func (*Response) SetWriter added in v0.0.15 

func (r *Response) SetWriter(w http.ResponseWriter)

SetWriter sets the http.ResponseWriter instance for this Response.

func (*Response) Size added in v0.0.13 

func (r *Response) Size() int64

Size returns the current size, in bytes, of the response.

func (*Response) Status added in v0.0.13 

func (r *Response) Status() int

Status returns the HTTP status code of the response.

func (*Response) Write added in v0.0.13 

func (r *Response) Write(b []byte) (n int, err error)

Write wraps and implements the http.Response.Write specification. Additionally, Write will increment the size of the current response. See http.Response.Write(https://golang.org/pkg/net/http/#Response.Write)

func (*Response) WriteHeader added in v0.0.13 

func (r *Response) WriteHeader(code int)

WriteHeader sends an HTTP response header with status code. If WriteHeader is not called explicitly, the first call to Write will trigger an implicit WriteHeader(http.StatusOK). Thus explicit calls to WriteHeader are mainly used to send error codes.

func (*Response) Writer added in v0.0.13 

func (r *Response) Writer() http.ResponseWriter

Writer returns the http.ResponseWriter instance for this Response.

type Route added in v1.0.0 

type Route struct {
	Method  string
	Path    string
	Handler Handler
}

Route contains a handler and information for matching against requests.

type Router added in v0.0.16 

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

Router is the registry of all registered routes for an Echo instance for request matching and handler dispatching.

Router implements the http.Handler specification and can be registered to serve requests.

func NewRouter 

func NewRouter(e *Echo) *Router

NewRouter returns a new Router instance.

func (*Router) Add added in v0.0.16 

func (r *Router) Add(method, path string, h HandlerFunc, e *Echo)

Add registers a new route with a matcher for the URL path.

func (*Router) Find added in v0.0.16 

func (r *Router) Find(method, path string, ctx *Context) (h HandlerFunc, e *Echo)

Find dispatches the request to the handler whos route is matched with the specified request path.
