A Credentials type representing "anonymous" Google OAuth2.0 credentials.
This is only useful in two cases: (a) in testing, where you want to access a test bench without having to worry about authentication or SSL setup, and (b) when accessing publicly readable resources (e.g. a Google Cloud Storage object that is readable by the "allUsers" entity), which requires no authentication or authorization.
Constructors
AnonymousCredentials()
Functions
virtual AuthorizationHeader()
While other Credentials subclasses return a string containing an Authorization HTTP header from this method, this class always returns an empty string as its value.
Some Credentials types can locally sign a blob, most often just on behalf of an specific service account. This function returns an error if the credentials cannot sign the blob at all, or if the service account is a mismatch.
