react quill中图片上传由默认转成base64改成上传到服务器的方法

使用react-quill富文本编辑器，里面处理图片是默认转成base64，提交到后台的时候文件太大，因此这里改写处理image的逻辑，改成上传到服务器。

具体代码如下：

配置1

import Quill from \'quill\'
import ReactQuill from \'react-quill\'
import \'react-quill/dist/quill.core.css\'
import \'react-quill/dist/quill.snow.css\'
import QuillEmoji from \'quill-emoji\'
import \'quill-emoji/dist/quill-emoji.css\'

Quill.register({
  \'modules/emoji-toolbar\': QuillEmoji.ToolbarEmoji,
  // \'modules/emoji-textarea\': QuillEmoji.TextAreaEmoji,
  \'modules/emoji-shortname\': QuillEmoji.ShortNameEmoji
})

const toolbarContainer = [
  [{ \'size\': [\'small\', false, \'large\', \'huge\'] }], // custom dropdown
  [{ \'font\': [] }],
  [{ \'header\': 1 }, { \'header\': 2 }],        // custom button values
  [\'bold\', \'italic\', \'underline\', \'strike\'],    // toggled buttons
  [{ \'align\': [] }],
  [{ \'indent\': \'-1\' }, { \'indent\': \'+1\' }],     // outdent/indent
  [{ \'direction\': \'rtl\' }],             // text direction
  [{ \'script\': \'sub\' }, { \'script\': \'super\' }],   // superscript/subscript
  [\'blockquote\', \'code-block\'],

  [{ \'list\': \'ordered\' }, { \'list\': \'bullet\' }],
  [{ \'color\': [] }, { \'background\': [] }],
  [\'emoji\', \'image\', \'video\', \'link\'],

  [\'clean\']
]

配置2

<ReactQuill
  ref={ref => this.quillRef = ref}
  placeholder=\"填写活动详情~\"
  theme=\"snow\"
  value={this.state.detailTpl}
  onChange={this.handleChangeDetail}
  modules={{
    toolbar: {
      container: toolbarContainer,
      handlers: {
        image: this.imageHandler
      }
    },
    \'emoji-toolbar\': true,
    // \'emoji-textarea\': true,
    \'emoji-shortname\': true,
  }}
/>

图片处理方法

imageHandler = () => {
  this.quillEditor = this.quillRef.getEditor()
  const input = document.createElement(\'input\')
  input.setAttribute(\'type\', \'file\')
  input.setAttribute(\'accept\', \'image/*\')
  input.click()
  input.onchange = async () => {
    const file = input.files[0]
    const formData = new FormData()
    formData.append(\'quill-image\', file)
    const res = await uploadFile(formData) 
    const range = this.quillEditor.getSelection()
    const link = res.data[0].url

    // this part the image is inserted
    // by \'image\' option below, you just have to put src(link) of img here. 
    this.quillEditor.insertEmbed(range.index, \'image\', link)
  }
}
