Nahm das Skript, das in der Kurzanleitung enthalten war und nach der ersten Einrichtung schien alles in Ordnung zu sein. Versucht, die ListMessages-Funktion zu verwenden, die sie in den Dokumenten enthalten, und abhängig von der Abfrage, die ich verwende, erhalte ich eine andere Antwort als wenn ich die Testversion im Web verwende. Zum BeispielGmail API - Auflisten von Nachrichten funktioniert nicht mit einigen Abfragen
messages = ListMessagesMatchingQuery(service, 'me', query=' from:-me')
funktioniert gut, jedoch
messages = ListMessagesMatchingQuery(service, 'me', query='after:1504748301 from:-me')
funktioniert nicht, dass ich keine Nachrichten zurück empfangen. Online erhalte ich 22 Nachrichten
Ähnlich funktioniert dies nicht funktionieren:
messages = ListMessagesMatchingQuery(service, 'me', query='is:unread from:-me')
Ich dachte, vielleicht war es mein Umfang so Ich habe meine Anmeldeinformationen zu löschen und Ausprobieren verschiedener Bereiche ohne Erfolg.
