我尝试关注azure storage Samples,并能够上传Blob。我正在尝试获取上传的Blob的Uri,但我无法获得Uri。
在以前的SDK v7中,我能够执行blobItem.getUri(),但在新版本中找不到它。我尝试了以下操作,但是元数据没有Uri,它实际上是属性。我如何获得Uri
blobURL.upload(Flowable.just(ByteBuffer.wrap(image)), image.length, headers, mData, null, null)
.flatMap(bulkBlockBlobUploadResponse -> {
this.getContext().getLogger().info(bulkBlockBlobUploadResponse.headers().eTag());
return Single.just(true);
})
.flatMap(response ->
// Query the blob's properties and metadata.
this.getBlockBlobURL().getProperties(null, null))
.flatMap(blobGetPropertiesResponse -> {
this.getContext().getLogger().info(blobGetPropertiesResponse.headers().metadata().toString());
return Single.just(true);
})

这可能是由于sdk版本不同造成的,有示例可供参考。
static void getBlob(BlockBlobURL blobURL, File sourceFile) {
try {
// Get the blob using the low-level download method in BlockBlobURL type
// com.microsoft.rest.v2.util.FlowableUtil is a static class that contains helpers to work with Flowable
blobURL.download(new BlobRange(0, Long.MAX_VALUE), null, false)
.flatMapCompletable(response -> {
AsynchronousFileChannel channel = AsynchronousFileChannel.open(Paths
.get(sourceFile.getPath()), StandardOpenOption.CREATE, StandardOpenOption.WRITE);
return FlowableUtil.writeFile(response.body(), channel);
}).doOnComplete(()-> System.out.println("The blob was downloaded to " + sourceFile.getAbsolutePath()))
// To call it synchronously add .blockingAwait()
.subscribe();
} catch (Exception ex){
System.out.println(ex.toString());
}
}

回答得有点晚,但是在 BlockBlobURL 对象上,您具有 toURL()方法。 因此,仅需执行以下操作即可获取URI:
BlockBlobURL my_blob = ... // your call to obtain the BlockBlobURL
URI blob_uri = blob.toURL().toURI();
