Question

这是我目前用于上传任务的代码：

app
|
  src1->com->example->testing->Main.java

  src2->com->another_example->another_testing->Library.java

它不起作用（所有上传的文件都被破坏）。我知道我需要做这样的事情：

$imagesDropzone.dropzone
  init: ->
    this.on 'sending', (file, xhr) ->
      xhr.setRequestHeader 'Content-Type', file.type

  url: 'https://www.googleapis.com/upload/drive/v2/files?uploadType=media'
  method: 'post'
  maxFileSize: 5
  paramName: 'images-dropzone-input'
  headers:
    'Authorization': "Bearer #{ uploadBundle.accessToken }"
  addRemoveLinks: 'dictRemoveFile'

但我不知道该拨打电话的地点。如何覆盖Dropzone的xhr.send file行为？

Answer 1

在看了Dropzone的源代码之后，我想办法通过覆盖实例方法uploadFiles来实现它：

imagesDropzoneInstance = new Dropzone '#imagesDropzone',
  url: 'https://www.googleapis.com/upload/drive/v2/files?uploadType=media'
  method: 'post'
  maxFileSize: 5
  paramName: 'images-dropzone-input'
  headers:
    'Authorization': "Bearer #{ uploadBundle.accessToken }"
  addRemoveLinks: 'dictRemoveFile'

imagesDropzoneInstance.uploadFiles = (files) ->
  uploadFiles: (files) ->

    .. copy the uploadFiles method of Dropzone, modify, then paste here..

    # Add the end:
    xhr.send files[0] # This overrides the default upload behavior.

使用Dropzone将文件上传到Google云端硬盘
