node.js - AWS S3 x-amz-meta 错误与非字符串值 : InvalidHeader and InvalidParameterType

Question

尝试使用带有可选元数据参数的 Node.js AWS sdk s3Client.upload 时:

const AWS = require('aws-sdk')
const s3Client = new AWS.S3({
  params: {
    Key: key,
    secret: secret
  }
})

let uploadParams = {
  Bucket: '',
  Key: '',
  Body: '',
  ACL: 'public-read',
  Metadata: {
    dummy_value: null
  }

s3Client.upload(uploadParams, function(err, data) {
  console.log('Upload: ', data)
}

抛出错误:

InvalidHeader: Header x-amz-meta-dummy_value contains invalid value

Answer 1

不幸的是，AWS S3 SDK documentation不涵盖 x-amz-meta- 前置元数据属性的输入值的有效值。

dummy_value 必须是字符串

抛出错误:

• undefined//InvalidHeader: header x-amz-meta-dummy_value 包含无效值
• null//InvalidHeader: header x-amz-meta-dummy_value包含无效值
• 12//无效参数类型:预期params.Metadata['dummy_value'] 为字符串
