使用Node.js获取Blob版本ID列表时遇ReferenceError错误求助

尝试使用Node.js获取Blob版本ID列表，编写代码如下：

async function getBlobNameAndVersions() {
    
  for await (const blob of containerClient.listBlobsFlat(includeVersions?: true)) {
    
    const tempBlockBlobClient = containerClient.getBlockBlobClient(blob.name);

    console.log(`\n\tname: ${blob.versionId}\n\tURL: ${tempBlockBlobClient.name}\n`);

  }

}

getBlobNameAndVersions()

运行后收到错误提示：ReferenceError: inlcudeVersions is not defined。

查看listBlobsFlat的参考文档，其定义为：

listBlobsFlat(options?: ContainerListBlobsOptions): PagedAsyncIterableIterator<BlobItem, ContainerListBlobFlatSegmentResponse>;
/**
 * Returns an AsyncIterableIterator for ContainerListBlobHierarchySegmentResponse
 *
 * @param delimiter - The character or string used to define the virtual hierarchy
 * @param marker - A string value that identifies the portion of
 *                          the list of blobs to be returned with the next listing operation. The
 *                          operation returns the ContinuationToken value within the response body if the
 *                          listing operation did not return all blobs remaining to be listed
 *                          with the current page. The ContinuationToken value can be used as the value for
 *                          the marker parameter in a subsequent call to request the next page of list
 *                          items. The marker value is opaque to the client.
 * @param options - Options to list blobs operation. 

且ContainerListBlobsOptions接口包含includeVersions选项：

export declare interface ContainerListBlobsOptions extends CommonOptions {
     * Specifies whether versions should be included in the enumeration. Versions are listed from oldest to newest in the response.
     */
    includeVersions?: boolean;
}

1. 修复参数传递语法错误 #

listBlobsFlat接收的是一个可选的配置对象，includeVersions?: true是TypeScript接口的定义语法，不能直接用于函数调用。正确做法是传入包含includeVersions属性的对象。

错误提示中的inlcudeVersions是拼写笔误（少了一个c），但核心问题是参数传递方式错误。

2. 修正输出逻辑错误 #

原代码输出项对应关系错误：

• blob.versionId是版本ID，需对应"版本ID"输出
• tempBlockBlobClient.name是Blob名称，tempBlockBlobClient.url才是Blob的完整访问URL

修改后的完整代码 #

async function getBlobNameAndVersions() {
  // 传入配置对象开启版本枚举
  for await (const blob of containerClient.listBlobsFlat({ includeVersions: true })) {
    const tempBlockBlobClient = containerClient.getBlockBlobClient(blob.name);
    // 修正输出内容，明确区分各字段含义
    console.log(`
      Blob名称: ${blob.name}
      版本ID: ${blob.versionId}
      Blob访问URL: ${tempBlockBlobClient.url}
    `);
  }
}

getBlobNameAndVersions();

关键注意点 #

• 需确保目标存储容器已开启版本控制，否则blob.versionId会返回undefined
• listBlobsFlat({ includeVersions: true })会返回所有Blob的历史版本，按从旧到新的顺序排列
