Types

type FaultInjection

type FaultInjection struct {
	// Embed the default plugin here,
	// so that we don't need to reimplement all the methods.
	plugin.DefaultPlugin
}

FaultInjection is used in the benchmark

func (*FaultInjection) Name

func (p *FaultInjection) Name() string

func (*FaultInjection) ParseConf

func (p *FaultInjection) ParseConf(in []byte) (interface{}, error)

func (*FaultInjection) RequestFilter

func (p *FaultInjection) RequestFilter(conf interface{}, w http.ResponseWriter, r pkgHTTP.Request)

type FaultInjectionConf

type FaultInjectionConf struct {
	Body       string `json:"body"`
	HttpStatus int    `json:"http_status"`
	Percentage int    `json:"percentage"`
}

type LimitReq

type LimitReq struct {
	// Embed the default plugin here,
	// so that we don't need to reimplement all the methods.
	plugin.DefaultPlugin
}

LimitReq is a demo for a real world plugin

func (*LimitReq) Name

func (p *LimitReq) Name() string

func (*LimitReq) ParseConf

func (p *LimitReq) ParseConf(in []byte) (interface{}, error)

ParseConf is called when the configuration is changed. And its output is unique per route.

func (*LimitReq) RequestFilter

func (p *LimitReq) RequestFilter(conf interface{}, w http.ResponseWriter, r pkgHTTP.Request)

RequestFilter is called when a request hits the route

type LimitReqConf

type LimitReqConf struct {
	Burst int     `json:"burst"`
	Rate  float64 `json:"rate"`
	// contains filtered or unexported fields
}

type ResponseRewrite

type ResponseRewrite struct {
	// Embed the default plugin here,
	// so that we don't need to reimplement all the methods.
	plugin.DefaultPlugin
}

ResponseRewrite is a demo to show how to rewrite response data.

func (*ResponseRewrite) Name

func (p *ResponseRewrite) Name() string

func (*ResponseRewrite) ParseConf

func (p *ResponseRewrite) ParseConf(in []byte) (interface{}, error)

func (*ResponseRewrite) ResponseFilter

func (p *ResponseRewrite) ResponseFilter(conf interface{}, w pkgHTTP.Response)

type ResponseRewriteConf

type ResponseRewriteConf struct {
	Status  int               `json:"status"`
	Headers map[string]string `json:"headers"`
	Body    string            `json:"body"`
}

type Say

type Say struct {
	// Embed the default plugin here,
	// so that we don't need to reimplement all the methods.
	plugin.DefaultPlugin
}

Say is a demo to show how to return data directly instead of proxying it to the upstream.

func (*Say) Name

func (p *Say) Name() string

func (*Say) ParseConf

func (p *Say) ParseConf(in []byte) (interface{}, error)

func (*Say) RequestFilter

func (p *Say) RequestFilter(conf interface{}, w http.ResponseWriter, r pkgHTTP.Request)

type SayConf

type SayConf struct {
	Body string `json:"body"`
}
