Functions ¶
func FromRequest ¶
FromRequest fetches the given request's request ID from the Headers. If one is found, it appends a new request ID and sets the comma separated value as the header. If one is not found, it sets a new request ID as the header.
Example ¶
var r http.Request
reqID, ok := FromRequest(&r)
if !ok {
log.Printf("when handling request from %s, no request ID", r.RemoteAddr)
return
}
log.Printf("The request ID is: %s", reqID)
func RequestIDFromContext ¶
RequestIDFromContext fetches a request ID from the given context if it exists.
func WithRequestID ¶
WithRequestID adds the given request ID to a context for processing later down the chain.
Example ¶
r := &http.Request{}
reqID, ok := FromRequest(r)
if !ok {
log.Printf("when handling request from %s, no request ID", r.RemoteAddr)
return
}
ctx := WithRequestID(r.Context(), reqID)
r = r.WithContext(ctx)
_ = r
