Functions

func Decode

func Decode(r io.Reader) (image.Image, error)

Decode returns an image.Image.

func Encode

func Encode(w io.Writer, m image.Image, t string) error

Encode writes the Image m to w in the format specified by Content-Type t.

func NewResponse

func NewResponse(r *http.Request, status int) *http.Response

NewResponse returns response

Example

package main

import (
	"fmt"
	"log"
	"net/http"

	"manael.org/x/manael"
)

func main() {
	req, err := http.NewRequest(http.MethodGet, "https://manael.test/", nil)
	if err != nil {
		log.Fatal(err)
	}

	resp := manael.NewResponse(req, http.StatusOK)

	fmt.Println(resp.StatusCode)
}

Output:

200

Types

type Proxy

type Proxy struct {
	Transport http.RoundTripper
}

A Proxy responds to an HTTP request.

func NewServeProxy

func NewServeProxy(u string) *Proxy

NewServeProxy returns a new Proxy given a upstream URL

Example

package main

import (
	"log"
	"net/http"

	"manael.org/x/manael"
)

func main() {
	p := manael.NewServeProxy("http://localhost:9000")

	err := http.ListenAndServe(":8080", p)
	if err != nil {
		log.Fatal(err)
	}
}

func (*Proxy) ServeHTTP

func (p *Proxy) ServeHTTP(w http.ResponseWriter, r *http.Request)

type Transport

type Transport struct {
	UpstreamURL string

	Base http.RoundTripper
}

Transport is an http.RoundTripper.

func (*Transport) RoundTrip

func (t *Transport) RoundTrip(req *http.Request) (*http.Response, error)

RoundTrip responds to an converted image.
