Question

我有一个应用程序，我将图像上传到Amazon S3服务。我已经实施了＃34;更新＆＃34;流（再次删除并重新添加新图像）。

有没有办法更新图像数据，而不是每次调用删除和重新添加功能，并更新新的URL？

我正在使用AWS iOS Swift SDK

//=>    Delete old profile image
if let originalImageUrl    = SessionManager.shared.curAccount?.pictureURL {
    let str                 = originalImageUrl.components(separatedBy: "/")

    let s3                  = AWSS3.default()
    let deleteRequest       = AWSS3DeleteObjectRequest()
    deleteRequest?.bucket   = Constants.AWS_S3.S3BucketName
    deleteRequest?.key      = str.last

    s3.deleteObject(deleteRequest!, completionHandler: { (s3Output, error) in
       if error != nil {
          self?.viewModel.profileOriginalImgURL.value   = originalImageUrl
       }
    })
}

和上传，类似的东西：

if let uploadRequest = AWSS3TransferManagerUploadRequest() {

    uploadRequest.body = urlProfileImageDir
    uploadRequest.key = ProcessInfo.processInfo.globallyUniqueString + "." + ext
    uploadRequest.bucket = Constants.AWS_S3.S3BucketName + "/" + Constants.AWS_S3.FolderProfileImages
    uploadRequest.contentType = "image/" + ext

    if let transferManager = AWSS3TransferManager.default() {
        transferManager.upload(uploadRequest).continue({ (task) -> Any? in
            if let error = task.error {
.....

在Amazon S3中更新文件但保留相同的URL
