如何将图像和文件上传到Azure Blob Node.js [英] How to upload images and files to Azure Blob Node.js
问题描述
我在Angular中有一个带有前端的node.js应用程序 我需要将文件和图像上传到Azure Blob 我已经根据MS文档创建了容器并设置了环境(
I have node.js application with frontend in Angular I need to upload files and images to Azure blob I have created container and setup the environment according to MS documentation (https://docs.microsoft.com/en-us/azure/storage/blobs/storage-quickstart-blobs-nodejs )
v12版本.
我的函数可用于创建创建的文件并将其上传到Azure blob,我不知道如何从客户端将发布的文件上传到Azure Blob,这是我在Node.js TypeScript中的代码
My functions works for creating and uploading the created file to Azure blob, I could not figure how do I upload the posted file from the client to Azure Blob, below is my code in Node.js TypeScript
import * as formidable from 'formidable';
import * as fs from 'fs';
const { BlobServiceClient } = require('@azure/storage-blob');
const uuidv1 = require('uuid/v1');
const dotenv = require('dotenv');
dotenv.config();
class BlobController {
private AZURE_STORAGE_CONNECTION_STRING = process.env.CONSTRINGBlob;
constructor(router) {
router.post('/file', this.uploadFile.bind(this));
}
//----Get Lookup tables dynamically-----------//
async uploadFile(req, res) {
const blobServiceClient = await BlobServiceClient.fromConnectionString(this.AZURE_STORAGE_CONNECTION_STRING);
// Create a unique name for the container
//const containerName = 'quickstart' + uuidv1();
const containerName = blobServiceClient.getContainerClient('mycontainer');
console.log('\t', containerName.containerName);
// Get a reference to a container
const containerClient = await blobServiceClient.getContainerClient(containerName.containerName);
let form = new formidable.IncomingForm();
form.parse(req, async function (err, fields, files) {
const blobName = 'test' + uuidv1() + files.file;
// Get a block blob client
const blockBlobClient = containerClient.getBlockBlobClient(blobName);
console.log('\nUploading to Azure storage as blob:\n\t', blobName);
// Upload data to the blob
const data = 'Hello test';
const uploadBlobResponse = await blockBlobClient.upload(data, data.length);
console.log("Blob was uploaded successfully. requestId: ", uploadBlobResponse.requestId);
});
}
}
module.exports = BlobController
任何人都可以帮助我如何使用Node.js上传发布到Azure blob的文件
could anyone help me on how can I upload files posted to Azure blob using Node.js
推荐答案
您快到了:).
请更改以下代码:
form.parse(req, async function (err, fields, files) {
const blobName = 'test' + uuidv1() + files.file;
// Get a block blob client
const blockBlobClient = containerClient.getBlockBlobClient(blobName);
console.log('\nUploading to Azure storage as blob:\n\t', blobName);
// Upload data to the blob
const data = 'Hello test';
const uploadBlobResponse = await blockBlobClient.upload(data, data.length);
console.log("Blob was uploaded successfully. requestId: ", uploadBlobResponse.requestId);
});
收件人:
form.parse(req, async function (err, fields, files) {
const file = files.file;
const blobName = 'test' + uuidv1() + files.file;
const contentType = file.type;
const filePath = file.path;//This is where you get the file path.
const blockBlobClient = containerClient.getBlockBlobClient(blobName);
const uploadBlobResponse = await blockBlobClient.uploadFile(filePath);
});
