request

Documentation

Overview

Package request contains everything around extracting info from a http request object. TODO: this package is temporary. Handlers must move into pkg/apiserver/handlers to avoid dependency cycle

var NamespaceSubResourcesForTest = sets.NewString(namespaceSubresources.List()...)

NamespaceSubResourcesForTest exports namespaceSubresources for testing in pkg/master/master_test.go, so we never drift

Functions

func WithRequestInfo

func WithRequestInfo(parent api.Context, info *RequestInfo) api.Context

WithRequestInfo returns a copy of parent in which the request info value is set

Types

type RequestInfo

type RequestInfo struct {
	// IsResourceRequest indicates whether or not the request is for an API resource or subresource
	IsResourceRequest bool
	// Path is the URL path of the request
	Path string
	// Verb is the kube verb associated with the request for API requests, not the http verb.  This includes things like list and watch.
	// for non-resource requests, this is the lowercase http verb
	Verb string

	APIPrefix  string
	APIGroup   string
	APIVersion string
	Namespace  string
	// Resource is the name of the resource being requested.  This is not the kind.  For example: pods
	Resource string
	// Subresource is the name of the subresource being requested.  This is a different resource, scoped to the parent resource, but it may have a different kind.
	// For instance, /pods has the resource "pods" and the kind "Pod", while /pods/foo/status has the resource "pods", the sub resource "status", and the kind "Pod"
	// (because status operates on pods). The binding resource for a pod though may be /pods/foo/binding, which has resource "pods", subresource "binding", and kind "Binding".
	Subresource string
	// Name is empty for some verbs, but if the request directly indicates a name (not in body content) then this field is filled in.
	Name string
	// Parts are the path parts for the request, always starting with /{resource}/{name}
	Parts []string
}

RequestInfo holds information parsed from the http.Request

func RequestInfoFrom

func RequestInfoFrom(ctx api.Context) (*RequestInfo, bool)

RequestInfoFrom returns the value of the RequestInfo key on the ctx

type RequestInfoFactory

type RequestInfoFactory struct {
	APIPrefixes          sets.String // without leading and trailing slashes
	GrouplessAPIPrefixes sets.String // without leading and trailing slashes
}

func (*RequestInfoFactory) NewRequestInfo

func (r *RequestInfoFactory) NewRequestInfo(req *http.Request) (*RequestInfo, error)

TODO write an integration test against the swagger doc to test the RequestInfo and match up behavior to responses NewRequestInfo returns the information from the http request. If error is not nil, RequestInfo holds the information as best it is known before the failure It handles both resource and non-resource requests and fills in all the pertinent information for each. Valid Inputs: Resource paths /apis/{api-group}/{version}/namespaces /api/{version}/namespaces /api/{version}/namespaces/{namespace} /api/{version}/namespaces/{namespace}/{resource} /api/{version}/namespaces/{namespace}/{resource}/{resourceName} /api/{version}/{resource} /api/{version}/{resource}/{resourceName}

Special verbs without subresources: /api/{version}/proxy/{resource}/{resourceName} /api/{version}/proxy/namespaces/{namespace}/{resource}/{resourceName} /api/{version}/redirect/namespaces/{namespace}/{resource}/{resourceName} /api/{version}/redirect/{resource}/{resourceName}

Special verbs with subresources: /api/{version}/watch/{resource} /api/{version}/watch/namespaces/{namespace}/{resource}

NonResource paths /apis/{api-group}/{version} /apis/{api-group} /apis /api/{version} /api /healthz /
