我下载了存储模拟器，并在存储模拟器容器中上传了一个blob，后来用Nodejs @azure/storage-blob包成功下载了它，请参阅下面：-

我的存储浏览器：-

参考：-Link1

现在，我使用下面的代码下载了带有@azure/storage-blob包的blob，并通过引用来自此MS文档的代码。

验证码：-

const { BlobServiceClient } = require("@azure/storage-blob");

// Connection string for the Azure Blob Storage emulator
const connectionString = "AccountName=xxxstoreaccount1;AccountKey=xxxxxxxxxxxxxxxxxxxtq/K1SZFPTOtr/xxxxxGMGw==;DefaultEndpointsProtocol=http;BlobEndpoint=http://xxx.0.0.1:xx000/devstoreaccount1;QueueEndpoint=http://xxx.0.0.1:xx001/devstoreaccount1;TableEndpoint=http://xxx.0.0.1:xx002/devstoreaccount1;";

// Name of the container where the blob is stored
const containerName = "test";

// Name of the blob to download
const blobName = "blob2.txt";

async function downloadBlob() {
  // Create a BlobServiceClient object using the connection string
  const blobServiceClient = BlobServiceClient.fromConnectionString(connectionString);

  // Get a reference to the container
  const containerClient = blobServiceClient.getContainerClient(containerName);

  // Get a reference to the blob
  const blobClient = containerClient.getBlobClient(blobName);

  // Download the blob to a buffer
  const downloadResponse = await blobClient.download();
  const buffer = await streamToBuffer(downloadResponse.readableStreamBody);

  // Convert the buffer to a string
  const content = buffer.toString();

  console.log(`Downloaded blob content: ${content}`);
}

async function streamToBuffer(readableStream) {
  return new Promise((resolve, reject) => {
    const chunks = [];
    readableStream.on("data", (data) => {
      chunks.push(data instanceof Buffer ? data : Buffer.from(data));
    });
    readableStream.on("end", () => {
      resolve(Buffer.concat(chunks));
    });
    readableStream.on("error", reject);
  });
}

downloadBlob();

输出：-

Blob内容下载成功：-

您可以从存储资源管理器中获取存储模拟器存储帐户的连接字符串，参考以下内容：

确保再次重新安装@azure/storage-blob包，并再次尝试运行代码以解决错误。
您可以通过在终端中运行以下命令来安装@azure/storage-blob版本12.14.0：-

npm install @azure/storage-blob@12.14.0

我的@azure/storage-blob包：-
*命令-

npm list @azure/storage-blob
