Functions

func ExternalIP

func ExternalIP() (string, error)

ExternalIP returns the first IPv4/IPv6 available.

func ExternalIPv4

func ExternalIPv4() (string, error)

ExternalIPv4 returns the first IPv4 available.

func IPAddr

func IPAddr() net.IP

IPAddr gets the external ipv4 address and converts into a libp2p formatted value.

func Method

func Method(auth string) authorization.Method

Method returns the authorizationmethod.AuthorizationMethod corresponding with the parameter value.

func NewExecutionRPCClient

func NewExecutionRPCClient(ctx context.Context, endpoint Endpoint, headers http.Header) (*gethRPC.Client, error)

func NewHttpClientWithSecret

func NewHttpClientWithSecret(secret, id string) *http.Client

NewHttpClientWithSecret returns a http client that utilizes jwt authentication.

func SortAddresses

func SortAddresses(ipAddrs []net.IP) []net.IP

SortAddresses sorts a set of addresses in the order of ipv4 -> ipv6.

Types

type AuthorizationData

type AuthorizationData struct {
	Method authorization.Method
	Value  string
	JwtId  string
}

AuthorizationData holds all information necessary to authorize with HTTP.

func (*AuthorizationData) Equals

func (d *AuthorizationData) Equals(other AuthorizationData) bool

Equals compares two authorization data objects for equality.

func (*AuthorizationData) ToHeaderValue

func (d *AuthorizationData) ToHeaderValue() (string, error)

ToHeaderValue retrieves the value of the authorization header from AuthorizationData.

type Endpoint

type Endpoint struct {
	Url  string
	Auth AuthorizationData
}

Endpoint is an endpoint with authorization data.

func HttpEndpoint

func HttpEndpoint(eth1Provider string) Endpoint

HttpEndpoint extracts an httputils.Endpoint from the provider parameter.

func (Endpoint) Equals

func (e Endpoint) Equals(other Endpoint) bool

Equals compares two endpoints for equality.

func (Endpoint) HttpClient

func (e Endpoint) HttpClient() *http.Client

HttpClient creates a http client object dependant on the properties of the network endpoint.
