如何从node.js创建Azure AppendBlob

Question

I have installed the npm azure-storage package.

On Azure I have created a Storage Account and a container.

I then try to create an Append Blob:

const azure = require('azure-storage');
const service = azure.createBlobService("[ACCOUNT]", "[KEY]");
service.createAppendBlobFromText("[CONTAINER]",
                                 "some-blob-name", 
                                 "some-text", 
                                 {},
                                (err, result) => {
   console.log('err ->',err);
   console.log('result ->',result);
});

The result of calling this is:

err -> { Error

  code: 'BlobTypeNotSupported',
  statusCode: 400,
  requestId: 'ed1777f4-601c-00cf-19a0-bb77ba000000' }
result -> null

I have not been able to find anything, when searching for the error.

Am I missing something here?

Please check the redundancy kind of the storage account in which you're trying to create this blob.

Blob type support varies by the storage account redundancy kind.

For example, ZRS Classic redundancy kind of storage account only supports Block Blob while Premium LRS redundancy kind of storage account only supports Page Blob .
