我正在使用名爲「imdb-datasets」的亞馬遜aws s3 imdb存儲區來顯示各種電影信息。在嘗試此操作之前,我使用自己的存儲桶測試了代碼,並設法從Android設備上傳和下載測試文件到我的存儲桶,反之亦然。但在嘗試使用imdb-datasets桶的同樣方法時,我開始接受拒絕403的錯誤。在做了一些研究之後,我發現可能的問題是我必須在代碼中指定它是請求者支付的存儲桶。我試圖實現請求者支付位(註釋掉的代碼),但它使我的應用程序崩潰。我不知道如何在我的應用程序中實現它,因爲我無法找到任何指南或解決方案。任何想法如何做到這一點?訪問被拒絕錯誤imdb s3存儲桶
編輯:我也給了應用程序的權限,以便能夠通過Android設備設置通過清單和手動在應用程序中訪問存儲。還分配了與iam用戶和imdb存儲桶的角色策略。
