Overview ¶
Package upstream provides utilities for propagating HTTP headers from incoming API requests to outbound toolset HTTP calls.

Functions ¶
func Handler ¶
Handler wraps an http.Handler to store the incoming HTTP request headers in the request context for downstream toolset forwarding.
func HeadersFromContext ¶
HeadersFromContext retrieves upstream HTTP headers from the context. Returns nil if no headers are present.
func NewHeaderTransport ¶
func NewHeaderTransport(base http.RoundTripper, headers map[string]string) http.RoundTripper
NewHeaderTransport wraps an http.RoundTripper to set custom headers on every outbound request. Header values may contain ${headers.NAME} placeholders that are resolved at request time from upstream headers stored in the request context.
func ResolveHeaders ¶
ResolveHeaders resolves ${headers.NAME} placeholders in header values using upstream headers from the context. Header names in the placeholder are case-insensitive, matching HTTP header convention.
For example, given the config header:
Authorization: ${headers.Authorization}
and an upstream request with "Authorization: Bearer token", the resolved value will be "Bearer token".
