Constants

const APIPath = "/api/" + shell.API_VERSION

APIPath is the path at which the API is mounted.

const (
	GatewayReedSolomonDirectoryCacheCapacity = 10
)

const HostUIDir = "/hostui"

const WebUIPath = "/btfs/QmVc2xjpt1xbBDu98QdDnPNS7nwyAgMvPbNpegJ9YyeLTd"

TODO: move to BTNS

Variables

var HostUIOption = StaticOption("hostui", HostUIDir)

var WebUIOption = RedirectOption("webui", WebUIPath)

var WebUIPaths = []string{
	WebUIPath,
}

this is a list of all past webUI paths.

Functions

func ListenAndServe

func ListenAndServe(n *core.IpfsNode, listeningMultiAddr string, options ...ServeOption) error

ListenAndServe runs an HTTP server listening at |listeningMultiAddr| with the given serve options. The address must be provided in multiaddr format.

TODO intelligently parse address strings in other formats so long as they unambiguously map to a valid multiaddr. e.g. for convenience, ":8080" should map to "/ip4/0.0.0.0/tcp/8080".

func Serve

func Serve(node *core.IpfsNode, lis net.Listener, options ...ServeOption) error

Serve accepts incoming HTTP connections on the listener and pass them to ServeOption handlers.

Types

type GatewayConfig

type GatewayConfig struct {
	Headers      map[string][]string
	Writable     bool
	PathPrefixes []string
}

type IpfsNodeCollector

type IpfsNodeCollector struct {
	Node *core.IpfsNode
}

func (IpfsNodeCollector) Collect

func (c IpfsNodeCollector) Collect(ch chan<- prometheus.Metric)

func (IpfsNodeCollector) Describe

func (_ IpfsNodeCollector) Describe(ch chan<- *prometheus.Desc)

func (IpfsNodeCollector) PeersTotalValues

func (c IpfsNodeCollector) PeersTotalValues() map[string]float64

type ReedSolomonDirectory

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

func (ReedSolomonDirectory) Size

func (d ReedSolomonDirectory) Size() uint64

type ServeOption

type ServeOption func(*core.IpfsNode, net.Listener, *http.ServeMux) (*http.ServeMux, error)

ServeOption registers any HTTP handlers it provides on the given mux. It returns the mux to expose to future options, which may be a new mux if it is interested in mediating requests to future options, or the same mux initially passed in if not.

func CheckVersionOption

func CheckVersionOption() ServeOption

CheckVersionOption returns a ServeOption that checks whether the client btfs version matches. Does nothing when the user agent string does not contain `/go-btfs/`

func CommandsOption

func CommandsOption(cctx oldcmds.Context) ServeOption

CommandsOption constructs a ServerOption for hooking the commands into the HTTP server. It will NOT allow GET requests.

func CommandsROOption

func CommandsROOption(cctx oldcmds.Context) ServeOption

CommandsROOption constructs a ServerOption for hooking the read-only commands into the HTTP server. It will allow GET requests.

func CommandsRemoteOption

func CommandsRemoteOption(cctx oldcmds.Context) ServeOption

CommandsRemoteOption constructs a ServerOption for hooking the public-facing, remote commands into the HTTP server.

func GatewayOption

func GatewayOption(writable bool, paths ...string) ServeOption

func HostnameOption

func HostnameOption() ServeOption

HostnameOption rewrites an incoming request based on the Host header.

func LogOption

func LogOption() ServeOption

func MetricsCollectionOption

func MetricsCollectionOption(handlerName string) ServeOption

This adds collection of net/http-related metrics

func MetricsScrapingOption

func MetricsScrapingOption(path string) ServeOption

This adds the scraping endpoint which Prometheus uses to fetch metrics.

func MutexFractionOption

func MutexFractionOption(path string) ServeOption

MutexFractionOption allows to set runtime.SetMutexProfileFraction via HTTP using POST request with parameter 'fraction'.

func P2PProxyOption

func P2PProxyOption() ServeOption

P2PProxyOption is an endpoint for proxying a HTTP request to another btfs peer

func RedirectOption

func RedirectOption(path string, redirect string) ServeOption

func StaticOption

func StaticOption(path, dir string) ServeOption

func VersionOption

func VersionOption() ServeOption
