使用 s3 aws sdk 上传文件时写入结束错误

问题描述

我在 node.js 中使用 s3 (aws sdk) 将文件/图像上传到 Linode 对象存储。 对于非常小的文件（小于 1 MB）工作正常，但是当文件大于 1MB 时会引发以下错误：

error Error [ERR_STREAM_WRITE_AFTER_END]: write after end
at writeAfterEnd (_http_outgoing.js:643:15)
at ClientRequest.end (_http_outgoing.js:763:7)
at features.constructor.writeBody ({pathtoproject}/node_modules/aws-sdk/lib/http/node.js:137:14)
at ClientRequest.<anonymous> ({pathtoproject}/node_modules/aws-sdk/lib/http/node.js:102:14)

at TLSSocket.socketonData (_http_client.js:507:22)
at TLSSocket.emit (events.js:315:20)

这是我的上传功能：

const s3 = require('./index')
const { v4: uuidv4 } = require('uuid');

const uploadFile = (file,bucket) => {
const params = {
    Bucket: bucket,// pass your bucket name
    Key: `${uuidv4()}-${file.originalname}`,// file will be saved as testBucket/contacts.csv
    Body: file.buffer,ContentType: file.mimetype,ACL: 'public-read'
};
return new Promise((resolve,reject) => {
    s3.upload(params,(s3Err,data) => {
        if (s3Err) {
            reject(s3Err)
        } else {
            console.log(`Image uploaded at: ${data}`)
            resolve(data.Location)
        }
    });
 })
}  


module.exports = uploadFile

这是主要配置

var AWS = require("aws-sdk");

AWS.config.loadFromPath('./aws/config.json');

const s3 = new AWS.S3({ httpOptions: { timeout: 10 * 60 * 1000 }});

module.exports = s3
