NuxtJS2和Cloudinary上传接口:如何从Cloudinary中删除资产？

Question

我不熟悉在NuxtJS中使用Cloudinary API。如何使用NuxtJS应用程序从Cloudinary帐户中删除图像/资产？

这是我尝试过的：

modules/cloudinary/index.js：(创建安全签名和配置信息)

import { createHash } from 'crypto'
import bodyParser from 'body-parser'

export default function () {
  const config = this.options.privateRuntimeConfig.cloudinary

  this.nuxt.hook('render:setupMiddleware', (app) => {
    app.use(bodyParser.json())
    app.use('/api/cloudinary/signature', setSignature)
  })

  function setSignature(req, res) {
    try {
      const sha1 = createHash('sha1')
      const payload = []

      Object.keys(req.body).forEach((key) => {
        payload.push(`${key}=${req.body[key]}`)
      })

      sha1.update(payload.sort().join('&') + config.apiSecret)
      res.end(
        JSON.stringify({
          signature: sha1.digest('hex')
        })
      )
    } catch (error) {
      console.error(error)
    }
  }
}

DeleteImage.vue

<script> 
import cloudinary from 'cloudinary' <--// Node SDK: https://cloudinary.com/documentation/node_integration
export default {
  data() {
    return {
      loading: false,
      src: null
    }
  },
  methods: {
    async deleteFile() {
      const response = await fetch('/api/cloudinary/signature', {
        method: 'POST',
        // body: JSON.stringify(options),
        headers: {
          'Content-Type': 'application/json'
        }
      })

      const signature = response.json.signature
      console.log(signature) // <-- console logging here gets me the signature
      try {
        const asset = await cloudinary.v2.uploader.destroy(this.src, signature)
        console.log(asset)
      } catch (error) {
        console.error('error deleting image', error)
      }
    },
    
  }
}
</script>

我现在得到控制台错误：

cloudinary.js?9447:1 Uncaught TypeError: Cannot read properties of undefined (reading 'split')
    at Object.eval (cloudinary.js?9447:1)
    at eval (cloudinary.js:10)

    at __webpack_require__ (runtime.js:854)

我不知道我在做什么。抱歉的!

从Cloudinary帐户中删除资源可以通过Destroy API (用于单文件删除)或Admin API (用于批量删除)来完成。但是，两者都要求您使用帐户的api_secret。由于确实不建议在客户端代码中包含您的帐户的api_secret，因此使用这两个API删除资源应该在服务器端完成。

话虽如此，也可以通过自动过期的令牌从客户端删除(从上传时间起最多10分钟)。欲了解更多信息，请访问：https://cloudinary.com/documentation/upload_images#deleting_client_side_uploaded_assets
