我引用了MSDOC和CreateWriteStream来上传给定的内容文本到blob。

const  fs = require('fs');
const  path = require('path');
const { BlobServiceClient } = require('@azure/storage-blob');
const  connectionString = 'connection String';
const  containerName = 'sampath78';
const  blobName = 'file.txt';
const  filePath = path.join(__dirname, 'file.txt');
async  function  uploadToAzureBlobStorage() {
console.log('Writing data to local file...');
const  writeStream = fs.createWriteStream(filePath);
writeStream.write('Hello world!');
writeStream.end();
console.log('Uploading file to Azure Blob storage...');
const  blobServiceClient = BlobServiceClient.fromConnectionString(connectionString);
const  containerClient = blobServiceClient.getContainerClient(containerName);
const  blockBlobClient = containerClient.getBlockBlobClient(blobName);
const  stream = fs.createReadStream(filePath);
await  blockBlobClient.uploadStream(stream);
console.log(`File ${blobName} uploaded to Azure Blob storage.`);
}
uploadToAzureBlobStorage();

使用createReadStream Output：

Azure：

其他方法：

async  function  uploadBlob(containerName, blobName, data) {
const  blobServiceClient = BlobServiceClient.fromConnectionString("connectionstring");
const  containerClient = blobServiceClient.getContainerClient(containerName);
const  blockBlobClient = containerClient.getBlockBlobClient(blobName);
const  stream = Readable.from(data);
const  uploadOptions = {
bufferSize:  4 * 1024 * 1024,
maxBuffers:  20,
};
const  uploadResponse = await  blockBlobClient.uploadStream(
stream,
uploadOptions.bufferSize,
uploadOptions.maxBuffers,
{ blobHTTPHeaders: { blobContentType:  "text/plain" } }
);
console.log(

`Upload block blob ${blobName} successfully`,
uploadResponse.requestId
);
}
// Example usage

const  containerName = "sampath78";

const  blobName = "Hello.txt";

const  data = "Hello, world! Hi ";

uploadBlob(containerName, blobName, data).catch((error) => {

console.error("Error uploading blob:", error);

});

输出：

Azure：

阅读bolb中的内容：

async  function  readBlob(containerName: string, blobName: string) {
const  blobServiceClient = BlobServiceClient.fromConnectionString( "connectionstring" );
const  containerClient = blobServiceClient.getContainerClient(containerName);
const  blockBlobClient = containerClient.getBlockBlobClient(blobName);
const  blobData = await  blockBlobClient.downloadToBuffer();
console.log(`Content of blob ${blobName}: ${blobData.toString()}`);

}

const  containerName = "sampath78";
const  blobName = "Hello.txt";

  

readBlob(containerName, blobName).catch((error) => {

console.error("Error reading blob:", error);

});

输出：
