删除Wasabi CDN桶204错误未删除

Question

因此，我试图以编程方式从我的一个桶中删除Wasabi CDN对象。我的请求是发回204并显示成功，但是没有任何东西被移动/删除。我使用节点/javascript来完成这个任务。

这是我的函数，应该删除桶。

​

import expressAsyncHandler from 'express-async-handler'
import User from '../../models/User.js'
import axios from 'axios'
import aws4 from 'aws4'

/**

 */

export const deleteUserBucket = expressAsyncHandler(async (req, res, next) => {
  try {
    const user = await User.findOne({ username: req.user.username })
    const username = user.username

    let request = {
      host: process.env.CDN_HOST,
      method: 'DELETE',
      url: `https://s3.wasabisys.com/truthcasting/${username}?force_delete=true`,
      path: `/truthcasting/${username}?force_delete=true`,
      headers: {
        'Content-Type': 'application/json',
      },
      service: 's3',
      region: 'us-east-1',
      maxContentLength: Infinity,
      maxBodyLength: Infinity,
    }

    let signedRequest = aws4.sign(request, {
      accessKeyId: process.env.CDN_KEY,
      secretAccessKey: process.env.CDN_SECRET,
    })

    //delete the Host and Content-Length headers
    delete signedRequest.headers.Host
    delete signedRequest.headers['Content-Length']

    const response = await axios(signedRequest)
    console.log(response.data)
    console.log('successfully deleted user bucket', response.status)

    return res.status(200).json({
      message: `Successfully deleted user bucket`,
    })
  } catch (error) {
    console.log(error)

    return res.status(500).json({
      message: `Problem with deleting user bucket`,
    })
  }
})

export default deleteUserBucket

​

当我将POSTMAN中的http请求发送到{{dev}api/admin/deleteuserbucket时，它会给我一个204 ok的响应，这就是响应。

​

{
    "message": "Successfully deleted user bucket"
}

​

然后我去我的Wasabi CDN桶检查它是否被删除，在本例中它是goodstock，它仍然在那里。感觉好像我错过了一些愚蠢的东西。

因此，要删除根桶中的内容，需要将其指向完整的对象。尽管如此，我在最初的邮政编码中设置它的方式是返回204(“这是预期的Wasabi API")，并且没有删除任何东西，因为我没有将它指向完整的对象路径。我还发现，如果您想要进行批删除而不是删除一个文件，您可以一个一个地使用aws节点包对对象执行get请求，然后使用该响应遍历对象并删除所需的内容。下面是一个例子。希望这能在不久的将来对某人有所帮助。

Answer 2

在S3中，删除桶API调用返回204No内容，并在成功删除时返回一个空响应体。

使用该URL，您将对对象(而不是桶)发出删除请求：

URL: `https://s3.wasabisys.com/truthcasting/${username}?force_delete=true`

在这个URL中传递的用户名将被解释为一个键，S3将在桶的根中查找一个对象。

另外，为什么不使用AWS来删除桶，而不是重新实现所有这些。检查AWS博士是否有此问题。
