Question

I am trying to upload a file to S3 using multer s3.However, it constantly fails.

aws.config.update（{ secretAccessKey：'key'， accessKeyId：'秘密'， }）;

var s3 = new aws.S3()

var upload = multer({
  storage: multerS3({
    s3: s3,
    bucket: 'pdsfiles',
    metadata: function (req, file, cb) {
      cb(null, {fieldName: file.fieldname});
    },
    key: function (req, file, cb) {
      cb(null, Date.now().toString())
    }
  })
})

这就是错误：

TypeError: this.s3.upload is not a function
at S3Storage. (/home/simran/Downloads/NODE-BACKEND/node_modules/multer-s3/index.js:172:26)
at /home/simran/Downloads/NODE-BACKEND/node_modules/multer-s3/index.js:58:10

at _combinedTickCallback (internal/process/next_tick.js:73:7)
at process._tickDomainCallback (internal/process/next_tick.js:128:9)

呼叫：

router.put('/updatePatternGrading/:pattern_number', upload.any(), function(req, res){
     console.log("request obj after manipulation", req.files);
     callAPI(req, res, fn.bind(apiObj, 'updatePatternGrading'));
 })

为什么我会这样做？

var upload = this.s3.upload（params）TypeError：this.s3.upload不是函数
