Express 如何修复错误->；NetworkingError:读取EconReset，无法在将头发送到客户端后设置头

我曾尝试使用multer软件包将大文件上传到aws s3位置存储。我提到了我的代码。已成功上载多达5 kb的文件。但是大文件没有上传。 请任何人建议我

这是我的路线文件

module.exports = app => {
  const s3 = require("../controllers/s3.controller.js");
  const multer = require('multer');
  const crypto = require("crypto");
  var storage = multer.memoryStorage();
  var upload = multer({storage: storage});  
  var router = require("express").Router();
  router.post('/upload', upload.single("file"), s3.doUpload);
};

s3.controller.js

const s3 = require('../config/s3.config');
const s3BucketName = process.env.BUCKET;

exports.doUpload =  (req, res) => {
    let bucketName = s3BucketName;
    bucketName = bucketName + "/testingCourse";
    const params = {
        Bucket: bucketName,
        Key: req.file.originalname, 
        Body: req.file.buffer
    }
    s3.upload(params, (err, data) => { 
        if (err) {
            res.status(500).send("Error -> " + err);
        }
        res.send({
          status:200,
          message:"OK",
          data:req.file.originalname 
        });
    });
}

文件没有上传，我得到了回复

感谢您出现此错误，因为当您收到错误时，您正在发送一个响应，之后您也将发送一个状态为200的响应

所以，只要在出现任何错误时返回该响应即可

if (err) {
          return res.status(500).send("Error -> " + err);
        }
