Functions

func ParseTargetUrl

func ParseTargetUrl(host string) (*url.URL, error)

func WithHost

func WithHost(ctx context.Context, host *Host) context.Context

WithHost returns a new context based on the provided parent ctx. HTTP client requests made with the returned context will use the provided host hooks

Types

type Host

type Host struct {
	// HostTarget is as like gRPC Naming for host service discovery, with Host in TargetUrl replaced if not empty.
	HostTarget string
	// resolve HostTarget to host and replace host if HostTarget resolved
	ReplaceHostInRequest bool

	// HostTargetAddrResolved is the host's addr resolved and picked from resolver.
	HostTargetAddrResolved resolver.Address
}

Host specifies TargetUrl and HostTarget to return a dynamic host.

func ContextHost

func ContextHost(ctx context.Context) *Host

ContextHost returns the Host associated with the provided context. If none, it returns nil.
