STUB

This package provides a set of utilities and helper methods to call a REST or RPC (over websocket) By using this package many of the boilerplate codes are not necessary anymore.

REST example:

    package main

import (
	"context"
	"net/http"

	"github.com/clubpay/ronykit/kit/stub"
)

func main() {
	ctx := context.Background()
	s := stub.New("webhook.site", stub.Secure())
	httpCtx := s.REST().
		SetMethod(http.MethodGet).
		SetPath("/22fda9e7-1660-406e-b11e-993e070f175e").
		SetQuery("someKey", "someValue").
		Run(ctx)
	defer httpCtx.Release()
}

type RESTCtx 

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

func (*RESTCtx) AutoRun 

func (hc *RESTCtx) AutoRun(
	ctx context.Context, route string, enc kit.Encoding, m kit.Message,
) *RESTCtx

AutoRun is a helper method, which fills the request based on the input arguments. It checks the route which is a path pattern, and fills the dynamic url params based on the `m`'s `tag` keys. Example: 

type Request struct {
		ID int64 `json:"id"`
		Name string `json:"name"`
}

AutoRun( 

	context.Background(),
  "/something/:id/:name",
  kit.JSON,
  &Request{ID: 10, Name: "customName"},

)

Is equivalent to:

SetPath("/something/10/customName"). Run(context.Background())

func (*RESTCtx) CopyBody 

func (hc *RESTCtx) CopyBody(dst []byte) []byte

CopyBody copies the body to `dst`. It creates a new slice and returns it if dst is nil.

func (hc *RESTCtx) DefaultResponseHandler(h RESTResponseHandler) *RESTCtx

func (*RESTCtx) DumpRequest 

func (hc *RESTCtx) DumpRequest() string

func (*RESTCtx) DumpRequestTo 

func (hc *RESTCtx) DumpRequestTo(w io.Writer) *RESTCtx

DumpRequestTo accepts a writer and will write the request dump to it when Run is executed.

Please refer to DumpResponseTo

func (*RESTCtx) DumpResponse 

func (hc *RESTCtx) DumpResponse() string

func (*RESTCtx) DumpResponseTo 

func (hc *RESTCtx) DumpResponseTo(w io.Writer) *RESTCtx

DumpResponseTo accepts a writer and will write the response dump to it when Run is executed. Example: 

httpCtx := s.REST().
							DumpRequestTo(os.Stdout).
							DumpResponseTo(os.Stdout).
							GET("https//google.com").
							Run(ctx)
defer httpCtx.Release()

**YOU MUST NOT USE httpCtx after httpCtx.Release() is called.**

func (*RESTCtx) Err

Err returns the error if any occurred during the execution.

func (*RESTCtx) Error 

func (hc *RESTCtx) Error() error

Error returns the error if any occurred during the execution.

func (*RESTCtx) GET 

func (hc *RESTCtx) GET(path string) *RESTCtx

func (*RESTCtx) GetBody 

func (hc *RESTCtx) GetBody() []byte

GetBody returns the body, but please note that the returned slice is only valid until Release is called. If you need to use the body after releasing RESTCtx then use CopyBody method.

func (*RESTCtx) GetHeader 

func (hc *RESTCtx) GetHeader(key string) string

GetHeader returns the header value for the key in the response

func (*RESTCtx) OPTIONS 

func (hc *RESTCtx) OPTIONS(path string) *RESTCtx

func (*RESTCtx) Release 

func (hc *RESTCtx) Release()

Release frees the allocated internal resources to be re-used. You MUST NOT refer to any method of this object after calling this method, if you call any method after Release has been called, the result is unpredictable.
