Amazon S3 Put Objekt 403 verbotener Fehler

Question

Ich habe versucht, direkt in Amazon S3-Bucket mit Client-SDK hochladen. Mein Code basiert auf diesem Beitrag: http://www.cheynewallace.com/uploading-to-s3-with-angularjs/. Ich kann den Upload tun und die Dateien mit S3-Konsole anzeigen. Jedoch, wenn ich versuche, putObject von Client-Seite auszuführen, bekomme ich 403 Fehler. Bitte helfen Sie mir herauszufinden, wo ich falsch liege.
