node.js - 在 JavaScript v10 SDK Nodejs 中将内容类型设置为图像

Question

当我尝试使用 Azure JS SDK v10 上传图像时，它会将它们显示为 application/octetstream。

这是我最初根据azure官方文档所做的

 async function uploadLocalFile(
    aborter,
    containerClient,
    filePath,
    file_guid,
  )

    filePath = path.resolve(filePath);  //Image file path
    const fileName = file_guid; //contains file name
    const blobClient = containerClient.getBlobClient(fileName);
    const blockBlobClient = blobClient.getBlockBlobClient();

    
    return await blockBlobClient.uploadFile(filePath, aborter);

  }

这是上传图像的 application/octetstream

然后我尝试了这个，设置标题并尝试将其设置为 image/jpeg，但这仍然使内容类型为 application/octetstream。

    filePath = path.resolve(filePath);
    const fileName = file_guid;
    const blobClient = containerClient.getBlobClient(fileName);
    const blockBlobClient = blobClient.getBlockBlobClient();

    const blobOptions = { blobHTTPHeaders: { blobContentType: 'image/jpeg' } };
    
    return await blockBlobClient.uploadFile(filePath, aborter, blobOptions);

  }

上传到azure blob存储时，有什么方法可以将图像的内容类型设置为image/jpeg吗？

我用你的代码测试了一下，设置了httpHeaderOptions，你可以引用这个接口(interface)说明:BlobHTTPHeaders ，下面是我的测试代码。

const { BlobServiceClient, StorageSharedKeyCredential } = require("@azure/storage-blob");
const path = require("path");
// Enter your storage account name and shared key
const account = "xxxx";
const accountKey = "xxxxxxxxxxxxxxxxxxxxxxxxxxx";

const sharedKeyCredential = new StorageSharedKeyCredential(account, accountKey);
const blobServiceClient = new BlobServiceClient(
  `https://${account}.blob.core.windows.net`,
  sharedKeyCredential
);

const containerName = "container";

async function main() {
     const containerClient = blobServiceClient.getContainerClient(containerName);

    const filePath = path.resolve("C:\\xxxxx\\me.jpg");
    const fileName = "bbb";
    const blobClient = containerClient.getBlobClient(fileName);
    const blockBlobClient = blobClient.getBlockBlobClient();
    const blobOptions = { blobHTTPHeaders: { blobContentType: 'image/jpeg' } };
    const uploadBlobResponse =await blockBlobClient.uploadFile(filePath,blobOptions);
    
    console.log(`Upload block blob test.txt successfully`);
}

main();
