如何在亚马逊网络服务 s3 (Android) 中同时上传多张图片？

Question

实际上我需要在 amazon s3 服务器上同时上传多张图片。这是我的单个文件上传代码::

TransferObserver transferObserver = transferUtility.upload(
                "selfiesharedev",     /* The bucket to upload to */
                mini_image_path,    /* The key for the uploaded object */
                file,        /* The file where the data to upload exists */
                CannedAccessControlList.PublicRead
        );

Answer 1

您可以使用 S3TransferUtility 来实现。 可以在以下位置找到示例： https://github.com/awslabs/aws-sdk-android-samples/tree/master/S3TransferUtilitySample

读书也不错... https://github.com/awslabs/aws-sdk-android-samples/blob/master/S3TransferUtilitySample/S3TransferUtilityTutorial.md ...理解示例中的代码。

请检查一下！

  TransferManager tm = new TransferManager(myCredentials);

    ObjectMetadataProvider metadataProvider = new ObjectMetadataProvider() {
        void provideObjectMetadata(File file, ObjectMetadata metadata) {
            // If this file is a JPEG, then parse some additional info
            // from the EXIF metadata to store in the object metadata
            if (isJPEG(file)) {
                metadata.addUserMetadata("original-image-date", 
                                         parseExifImageDate(file));
            }
        }
    }

    MultipleFileUpload upload = tm.uploadFileList(
            myBucket, myKeyPrefix, rootDirectory, fileList, metadataProvider);
