为什么我的图像显示状态200但不显示来自s3的图像

Question

This image shows that the image is uploaded, and fetched successfully but its nit displaying to the user, Can someone help

这是已经写好的代码

// Downloads from s3
function getFileStream(key) {
  const downloadParams = {
    Key: key,
    Bucket: 'icon-path-bucket',
  }

  return s3.getObject(downloadParams).createReadStream()
}

exports.getFileStream = getFileStream

这就是我请求图像的方式

const { getFileStream } = require('./s3bucket')
app.get('/images/:key', (req, res) => {
  const key = req.params.key

  const readStream = getFileStream(key)

  readStream.pipe(res)
})

这里可以做些什么？

Answer 1

似乎你对add the attachement的思念

添加附件的代码为

        app.get("/images/:key", (req, res) => {
            const key = req.params.key

            const readStream = getFileStream(key) 

            res.attachment(key);
            readStream.pipe(res)
        })

为了在亚马逊S3存储桶中显示相册的内容，应用程序的viewAlbum函数接受一个相册名称并为该相册创建亚马逊S3密钥。然后，该函数调用AWS.S3服务对象的listObjects方法，以获取相册中所有对象(照片)的列表。

函数的其余部分获取相册中的对象列表，并生成在网页上显示照片所需的HTML。
