使用 AdonisJS 5 的文件存储 (S3)

Question

在 AdonisJS v4 文档中，我们有这一部分解释如何将文件流式传输到 S3 存储桶。我在 AdonisJS v5 文档中寻找类似的东西，但它只是一个如何将文件上传到本地服务器的示例。

如果它还没有准备好，因为 Adonis 5 不是它的最新版本，这是通过 Adonis v5（特别是打字稿）将文件上传到 S3 的另一种方式？

Answer 1

我找到了一种使用 aws-sdk 执行此操作的方法，此代码并非 100% 我的代码：uploadToS3Bucket功能：import * as AWS from "aws-sdk";import { v4 as uuid } from "uuid";const s3 = new AWS.S3({&nbsp; region: process.env.AWS_REGION,&nbsp; secretAccessKey: process.env.AWS_SECRET_ACCESS_KEY,&nbsp; accessKeyId: process.env.AWS_ACCESS_KEY_ID,});export const uploadToS3Bucket = async (&nbsp; file: any,&nbsp; bucket: string): Promise<{ key: string; url: string }> => {&nbsp; try {&nbsp; &nbsp; const { type, subtype, extname } = file;&nbsp; &nbsp; let mimeType = type + "/" + subtype;&nbsp; &nbsp; let fileType = "image/jpg";&nbsp; &nbsp; const name = uuid() + "." + extname;&nbsp; &nbsp; let buffer = Buffer.from(JSON.stringify(file), "utf-8");&nbsp; &nbsp; await s3&nbsp; &nbsp; &nbsp; .putObject({&nbsp; &nbsp; &nbsp; &nbsp; Key: name,&nbsp; &nbsp; &nbsp; &nbsp; Bucket: bucket,&nbsp; &nbsp; &nbsp; &nbsp; ContentType: fileType,&nbsp; &nbsp; &nbsp; &nbsp; Body: buffer.toString("base64"),&nbsp; &nbsp; &nbsp; &nbsp; ACL: "public-read",&nbsp; &nbsp; &nbsp; })&nbsp; &nbsp; &nbsp; .promise();&nbsp; &nbsp; let url = `https://${bucket}.s3.amazonaws.com/${name}`;&nbsp; &nbsp; console.log(url);&nbsp; &nbsp; return {&nbsp; &nbsp; &nbsp; key: name,&nbsp; &nbsp; &nbsp; url,&nbsp; &nbsp; };&nbsp; } catch (err) {&nbsp; &nbsp; console.log(err);&nbsp; &nbsp; return err;&nbsp; }};在控制器中：public async store({ request }: HttpContextContract) {&nbsp; let file = getFileFromRequest(request, "defined_file_prop_name_here");&nbsp; if (file) {&nbsp; &nbsp; await uploadToS3Bucket(file, BUCKET_NAME);&nbsp; }}

Adonis 4 使用flydrive来实现 s3 存储，您也可以使用它来简化和节省时间。使用 flydrive 配置和实例化后非常简单//&nbsp;Supported&nbsp;drivers:&nbsp;"local",&nbsp;"s3",&nbsp;"gcs" await&nbsp;storage.disk('s3').put('testfile.txt',&nbsp;'filecontents');

您可以在没有 ACL 权限问题的情况下使用它不要忘记安装 S3 驱动器：https ://docs.adonisjs.com/guides/drive多个图像的示例：import Route from '@ioc:Adonis/Core/Route'import Drive from '@ioc:Adonis/Core/Drive'import fs from 'fs'import path from 'path'import { string } from '@ioc:Adonis/Core/Helpers'Route.post('upload', async ({ request }) => {&nbsp; &nbsp;const images = request.files('images')&nbsp; &nbsp;for (let image of images) {&nbsp; &nbsp; &nbsp; if (image !== null) {&nbsp; &nbsp; &nbsp; &nbsp; &nbsp;const slugFileName = string.camelCase(path.parse(image.clientName).name).toLowerCase();&nbsp; &nbsp; &nbsp; &nbsp; &nbsp;const fileName = `${slugFileName}.${image.extname}`&nbsp; &nbsp; &nbsp; &nbsp; &nbsp;const fileStream = fs.createReadStream(image.tmpPath!)&nbsp; &nbsp; &nbsp; &nbsp; &nbsp;await Drive.putStream(fileName, fileStream, {&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; contentType: image.headers['content-type']&nbsp; &nbsp; &nbsp; &nbsp; &nbsp;})&nbsp; &nbsp; &nbsp; }&nbsp; &nbsp;}})如果要上传单张图片：Route.post('upload', async ({ request }) => {&nbsp; &nbsp;const image = request.file('image')&nbsp; &nbsp; &nbsp; if (image !== null) {&nbsp; &nbsp; &nbsp; &nbsp; &nbsp;const slugFileName = string.camelCase(path.parse(image.clientName).name).toLowerCase();&nbsp; &nbsp; &nbsp; &nbsp; &nbsp;const fileName = `${slugFileName}.${image.extname}`&nbsp; &nbsp; &nbsp; &nbsp; &nbsp;const fileStream = fs.createReadStream(image.tmpPath!)&nbsp; &nbsp; &nbsp; &nbsp; &nbsp;await Drive.putStream(fileName, fileStream, {&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; contentType: image.headers['content-type']&nbsp; &nbsp; &nbsp; &nbsp; &nbsp;})&nbsp; &nbsp; &nbsp; }})
