Javascript 在Node.js中列出Azure blob存储和Readstream中的blob

这是我的代码，我是如何列出blob的

编辑

------------------------------------编辑------------------------------------------

我编辑了代码并在这个类型脚本中重写：

    const blobServiceClient = new BlobServiceClient(`https://${accountName}.blob.core.windows.net?${sasToken}`,
      pipeline)
    const containerClient = blobServiceClient.getContainerClient(containerName)
    console.log(containerClient)
    if (!containerClient.exists()) {
      console.log("the container does not exit")
      await containerClient.create()

    }
    const client = containerClient.getBlockBlobClient(this.currentFile.name)

    //name of uploded blob
    console.log(this.currentFile.name)
    //metaata from the blob
    console.log(client)

    //List each blobs in the container
    for await (const blob of containerClient.listBlobsFlat()) {
      console.log('\t', blob.name);
      const blockBlobClient = containerClient.getBlockBlobClient(blob.name);
      const downloadBlockBlobResponse = await blockBlobClient.download(0);
      console.log('\nDownloaded blob content...');
      console.log('\t', await streamToString(downloadBlockBlobResponse.readableStreamBody));
      //end of loop
  }



  async function streamToString(readableStream) {
    return new Promise((resolve, reject) => {
      const chunks = [];
      readableStream.on("data", (data) => {
        chunks.push(data.toString());
      });
      readableStream.on("end", () => {
        resolve(chunks.join(""));
      });
      readableStream.on("error", reject);
    });
  }

但随后我在浏览器中收到一个错误，称为：

错误：未捕获（承诺中）：TypeError:无法读取属性 未定义类型的“on”错误：无法读取未定义类型的属性“on”

通过调用

Download

方法下载blob。示例代码包括一个名为

streamToString

的助手函数，该函数用于将Node.js可读流读入字符串

将此代码添加到主函数的末尾：

const blockBlobClient = containerClient.getBlockBlobClient(blob.name);
const downloadBlockBlobResponse = await blockBlobClient.download(0);
console.log('\nDownloaded blob content...');
console.log('\t', await streamToString(downloadBlockBlobResponse.readableStreamBody));

// A helper function used to read a Node.js readable stream into a string
async function streamToString(readableStream) {
  return new Promise((resolve, reject) => {
    const chunks = [];
    readableStream.on("data", (data) => {
      chunks.push(data.toString());
    });
    readableStream.on("end", () => {
      resolve(chunks.join(""));
    });
    readableStream.on("error", reject);
  });
}

在主函数之后添加此辅助函数：

const blockBlobClient = containerClient.getBlockBlobClient(blob.name);
const downloadBlockBlobResponse = await blockBlobClient.download(0);
console.log('\nDownloaded blob content...');
console.log('\t', await streamToString(downloadBlockBlobResponse.readableStreamBody));

// A helper function used to read a Node.js readable stream into a string
async function streamToString(readableStream) {
  return new Promise((resolve, reject) => {
    const chunks = [];
    readableStream.on("data", (data) => {
      chunks.push(data.toString());
    });
    readableStream.on("end", () => {
      resolve(chunks.join(""));
    });
    readableStream.on("error", reject);
  });
}

尝试使用

blobServiceClient.downloadToBuffer（）

处理较小的文件（32位系统最高1Gb）。对于较大的文件，请尝试

blobServiceClient.downloadToFile（）

。参考参数信息仍然错误：错误运行示例：blobServiceClient.downloadFile不是一个函数我的错误，请尝试

等待（常量blob of blob）{console.log（`blob${i++}:${blob.name}）；常量blobClient=containerClient.getBlobClient（blob.name）；var stream=blobClient.downloadtobfer（）；//stream.pipe（res）}

谢谢Hemant。如何显示var流的内容？“流”是否包含blob内容？我编辑了它，然后在TypeScript中收到另一个错误
