Types

type Context

type Context struct {
	FResponseWriter     http.ResponseWriter
	FRequest            *http.Request
	FResponse           *http.Response
	FServed             bool
	FServedWithResponse bool
	FParams             map[string]string
	FStateBag           map[string]interface{}
	FBackendUrl         string
	FOutgoingHost       string
	FMetrics            filters.Metrics
	FTracer             opentracing.Tracer
}

Simple FilterContext implementation.

Example
package main

import (
	"fmt"
	"github.com/zalando/skipper/filters"
	"github.com/zalando/skipper/filters/filtertest"
)

type customFilter struct{}

func (f *customFilter) Request(ctx filters.FilterContext) {
	ctx.StateBag()["filter called"] = true
}

func (f *customFilter) Response(ctx filters.FilterContext) {}

func main() {
	// create a filter instance:
	filter := &customFilter{}

	// create a test context:
	ctx := &filtertest.Context{FStateBag: make(map[string]interface{})}

	// call the request handler method of the filter:
	filter.Request(ctx)
	fmt.Printf("%t", ctx.StateBag()["filter called"].(bool))

}
Output:

true

type Filter

type Filter struct {
	FilterName string
	Args       []interface{}
}

Noop filter, used to verify the filter name and the args in the route. Implements both the Filter and the Spec interfaces.

Example
package main

import (
	"github.com/zalando/skipper/filters/builtin"
	"github.com/zalando/skipper/filters/filtertest"
	"github.com/zalando/skipper/proxy"
	"github.com/zalando/skipper/routing"
	"github.com/zalando/skipper/routing/testdataclient"
	"log"
)

func main() {
	// create a test filter and add to the registry:
	fr := builtin.MakeRegistry()
	fr.Register(&filtertest.Filter{FilterName: "testFilter"})

	// create a data client, with a predefined route referencing the filter:
	dc, err := testdataclient.NewDoc(`Path("/some/path/:param") -> testFilter(3.14, "Hello, world!") -> "https://www.example.org"`)
	if err != nil {
		log.Fatal(err)
	}

	// create routing object:
	rt := routing.New(routing.Options{
		DataClients:    []routing.DataClient{dc},
		FilterRegistry: fr})
	defer rt.Close()

	// create an http.Handler:
	p := proxy.New(rt, proxy.OptionsNone)
	defer p.Close()
}
Output:

func (*Filter) CreateFilter

func (spec *Filter) CreateFilter(config []interface{}) (filters.Filter, error)

func (*Filter) Name

func (spec *Filter) Name() string

func (*Filter) Request

func (f *Filter) Request(ctx filters.FilterContext)

func (*Filter) Response

func (f *Filter) Response(ctx filters.FilterContext)
