NewContext returns a new Context carrying m. If m is nil, NewContext returns
ctx. NewContext is only used for writing tests which rely on Metadata.
Metadata
typeMetadatastruct{// EventID is a unique ID for the event. For example: "70172329041928".EventIDstring`json:"eventId"`// Timestamp is the date/time this event was created.Timestamptime.Time`json:"timestamp"`// EventType is the type of the event. For example: "google.pubsub.topic.publish".EventTypestring`json:"eventType"`// Resource is the resource that triggered the event.Resource*Resource`json:"resource"`}
FromContext extracts the Metadata from the Context, if present.
Resource
typeResourcestruct{// Service is the service that triggered the event.Servicestring`json:"service"`// Name is the name associated with the event.Namestring`json:"name"`// Type is the type of event.Typestring`json:"type"`// RawPath is the path to the resource type (deprecated).// It is used by the GCS notifications shown in// https://cloud.google.com/storage/docs/pubsub-notifications,// which populate the resource field as a string containing the topic// rather than as the expected dictionary.// It is also used when triggering Cloud Functions by [Firebase Realtime Database// Triggers](https://cloud.google.com/functions/docs/calling/realtime-data).RawPathstring`json:"-"`}
Resource holds Google Cloud Functions resource metadata.
Resource values are dependent on the event type they're from.
MarshalJSON specializes the Resource marshalling to handle the case where the
value is a string instead of a map. See the comment above on RawPath for why this
needs to be handled.
UnmarshalJSON specializes the Resource unmarshalling to handle the case where the
value is a string instead of a map. See the comment above on RawPath for why this
needs to be handled.
