react-fine-uploader想要在每个分块上传时重新加载浏览器窗口

Question

我已经得到了反应精细上传器，使用.NET Core REST API上传大块文件。块正确地写入文件系统，我发送了一个{"success": true} 200响应，这是Fine Uploader javascript似乎喜欢的。但现在，每次OK响应，浏览器都会提示我确认是否要重新加载窗口或取消。我不知道为什么会这样。如果我单击取消，下一个块将成功上传，我发送下一个OK响应，然后我再次获得相同的浏览器提示。可能是什么导致了这个？

如果我一直点击每个块的取消一直到结束，它将完成整个上传并触发块成功端点调用。我完全摸不着头脑。我试过一次关闭每个前端选项，但它没有帮助。任何想法都非常感激。

upload.js：

import React, { Component } from 'react'
import FineUploaderTraditional from 'fine-uploader-wrappers'
import Gallery from 'react-fine-uploader'
import 'react-fine-uploader/gallery/gallery.css'

const uploader = new FineUploaderTraditional({
  options: {
      debug: true,
      chunking: {
        enabled: true,
        concurrent: {
          enabled: false
        },
        success: {
          endpoint: '/api/File/LargeUploadComplete'
        }
      },
      deleteFile: {
        enabled: false
      },
      request: {
        endpoint: '/api/File/LargeUpload'
      },
      resume: {
        //enabled: true
      },
      retry: {
        showButton: true
        //, enableAuto: true
      }
  }
})

class Upload extends Component {
  render() {
    return (
      <Gallery uploader={uploader} />
    )
  }
}

export default Upload

Answer 1

并不是说有人真正关心，但是当我使用VS Code调试器时就会发生这种情况。显然它真的放慢了上传的块。我调整了一些设置（5个并发上传，每个5MB），我只是在正常模式下启动服务器，我不再得到错误了。希望这有助于某些可怜的羞怯。
