无法将文件上传到 Azure Blob Node.js

Question

尝试在 nodejs 中使用 @azure/storage-blob sdk 将文件上传到 azure blob 存储：

module.exports.createBlob = (blobName, containerName, blobContent) => {
  return new Promise(async (resolve, reject) => {
    try {
      const sharedKeyCredential = await this.createSharedAccessToken(blobName, 'c')
      const blobServiceClient = new BlobServiceClient(
    `https://${process.env.AZURE_BLOB_ACCOUNT}.blob.core.windows.net`,
    sharedKeyCredential
      )
      const containerClient = blobServiceClient.getContainerClient(containerName)
      const blockBlobClient = containerClient.getBlockBlobClient(blobName)
      const blob = await blockBlobClient.upload(blobContent, blobContent.length) // implement later
      resolve(blob)
    } catch (err) {
      console.log(err)
      reject(err)
    }
  })
}

module.exports.createSharedAccessToken = (blobName, permission) => {
  return new Promise(async (resolve, reject) => {
    const sharedKeyCredential = new StorageSharedKeyCredential(process.env.AZURE_BLOB_ACCOUNT, process.env.AZURE_BLOB_KEY)
    const containerName = process.env.AZURE_CONTAINER_NAME
    const startsOn = new Date()
    expiresOn.setMinutes(expiresOn.getMinutes() + parseInt(autoLogoutDuration.KeyValue))
    const blobSAS = generateBlobSASQueryParameters({
      containerName, // Required
      blobName, // Required
      permissions: BlobSASPermissions.parse(permission), // Required
      startsOn: startsOn, // Required
    },
    sharedKeyCredential // StorageSharedKeyCredential - `new StorageSharedKeyCredential(account, accountKey)`
    ).toString()
    resolve(decodeURI(blobSAS))
})
}

它不断抛出“NoAuthenticationInformation”错误。相同的凭据可用于下载现有的 blob，但无论我尝试什么上传都无法正常工作。任何帮助将不胜感激。

在此MS DOC 之后，我尝试重现您的问题，但能够使用 Node.js 将文件上传到我的 azure blob 容器中，而不会出现任何身份验证错误。

当您使用共享密钥凭证时，我们需要在我们的门户中拥有所有这些权限，如下所示：

我也在nodejs 中使用@azure/storage-blob sdk 在我的package.json 中。

还在我的testupload.js 文件中添加了@azure/storage-blob sdk

并将以下代码添加到我的testupload.js 文件中，因为我已经创建了容器，我刚刚评论了上面的屏幕截图代码。

const  account="testa";

const  sharedKeyCredential = new  StorageSharedKeyCredential("yourstorageaccountname", "your storage key connection string");

const  blobServiceClient1 = new  BlobServiceClient(

// When using AnonymousCredential, following url should include a valid SAS or support public access

`https://${account}.blob.core.windows.net`,

sharedKeyCredential

);

  

const  blobnewname="example2.txt"

blobContent="hi hello";

const  containerClient1 = blobServiceClient.getContainerClient("test")

const  blockBlobClient1= containerClient.getBlockBlobClient(blobnewname)

const  blob = blockBlobClient1.upload(blobContent, blobContent.length)

然后我可以测试我的文件并将其上传到 Azure blob 容器 以下是截图供参考：

更新：- 正如@Setanjan Roy 所建议的那样

另一种方式：- 为了摆脱这个，我们可以使用 new BlobServiceClient(https://${process.env.AZURE_BLOB_ACCOUNT}.blob.core.windows.net${sharedKeyCredential})
