vue-quill-editor 富文本编辑器 七牛 ivew，实现富文本编辑器上传图片到七牛,并可以调整图片大小

1、下载安装必须插件

cnpm i vue-quill-editor -S
// 可拖拽图片
cnpm i quill-image-drop-module -S
// 这两个是改变图片大小的
cnpm i quill-image-resize-module -S

2、引入html内容

<div id='quillEditorQiniu'>
    <quill-editor
      :style="'width: '100%'"
      v-model="content"
      ref="myQuillEditor"
      :options="editorOption"
      @change="onEditorChange($event)"
    >
    </quill-editor>
    <Upload
      class="avatar-uploader"
      :accept="'image/*'"
      :action="'https://upload.qiniup.com'"
      name='file'
      :data="updateParams"
      :show-upload-list="false"
      :on-success="uploadSuccess"
      :on-error="uploadError"
      :before-upload="beforeUpload"
    >
    </Upload>

注意如果想看upload详细讲解可以看我上一片文章：https://segmentfault.com/a/1190000021073631

3、首先配置工具栏显示图标

const toolbarOptions = [
  ['bold', 'italic', 'underline', 'strike'],
  [{'color': []}, { 'size': fontSizeStyle.whitelist }],
  [{ list: 'ordered' }, { list: 'bullet' }],
  [{ indent: '-1' }, { indent: '+1' }],
  ['link', 'image']
]

4、这里的其他图标都是系统给的，只有“size”字体选择下拉框，是我自己配置的，因为默认只有三种字体大小，我们需要扩展,在Quill上注册字体：

import { quillEditor } from 'vue-quill-editor'
// 富文本编辑器 quill editor 样式
import 'quill/dist/quill.core.css'
import 'quill/dist/quill.snow.css'
import 'quill/dist/quill.bubble.css'
import * as Quill from 'quill'
let fontSizeStyle = Quill.import('attributors/style/size')
fontSizeStyle.whitelist = ['12px', '14px', '16px', '20px', '24px', '36px']
Quill.register(fontSizeStyle, true)

5、使用配置项

data () {
    return {
        editorOption: {
        placeholder: '请输入',
        theme: 'snow',
        modules: {
          toolbar: {
            container: toolbarOptions
          }
        }
      },
    }
}

6、还需要修改css文件，我们最好建一个全局css覆盖quill的css样式

.ql-editor{
  min-height:150px;
}
.ql-snow .ql-tooltip[data-mode=link]::before {
  content: "请输入链接地址:";
}
.ql-snow .ql-tooltip.ql-editing a.ql-action::after {
    border-right: 0px;
    content: '保存';
    padding-right: 0px;
}
.ql-snow .ql-tooltip[data-mode=video]::before {
    content: "请输入视频地址:";
}
.ql-snow .ql-picker.ql-size .ql-picker-label::before,
.ql-snow .ql-picker.ql-size .ql-picker-item::before {
  content: '14px';
}
.ql-snow .ql-picker.ql-size .ql-picker-label[data-value=small]::before,

}
.ql-snow .ql-picker.ql-size .ql-picker-label[data-value=huge]::before,
.ql-snow .ql-picker.ql-size .ql-picker-item[data-value=huge]::before {
  content: '32px';
}

.ql-snow .ql-picker.ql-header .ql-picker-label::before,
.ql-snow .ql-picker.ql-header .ql-picker-item::before {
  content: '文本';
}
.ql-snow .ql-picker.ql-header .ql-picker-label[data-value="1"]::before,
.ql-snow .ql-picker.ql-header .ql-picker-item[data-value="1"]::before {
  content: '标题1';
}
.ql-snow .ql-picker.ql-header .ql-picker-label[data-value="2"]::before,
.ql-snow .ql-picker.ql-header .ql-picker-item[data-value="2"]::before {
  content: '标题2';
}
.ql-snow .ql-picker.ql-header .ql-picker-label[data-value="3"]::before,
.ql-snow .ql-picker.ql-header .ql-picker-item[data-value="3"]::before {
  content: '标题3';
}
.ql-snow .ql-picker.ql-header .ql-picker-label[data-value="4"]::before,
.ql-snow .ql-picker.ql-header .ql-picker-item[data-value="4"]::before {
  content: '标题4';
}
.ql-snow .ql-picker.ql-header .ql-picker-label[data-value="5"]::before,
.ql-snow .ql-picker.ql-header .ql-picker-item[data-value="5"]::before {
  content: '标题5';
}
.ql-snow .ql-picker.ql-header .ql-picker-label[data-value="6"]::before,
.ql-snow .ql-picker.ql-header .ql-picker-item[data-value="6"]::before {
  content: '标题6';
}

.ql-snow .ql-picker.ql-font .ql-picker-label::before,
.ql-snow .ql-picker.ql-font .ql-picker-item::before {
  content: '标准字体';
}
.ql-snow .ql-picker.ql-font .ql-picker-label[data-value=serif]::before,
.ql-snow .ql-picker.ql-font .ql-picker-item[data-value=serif]::before {
  content: '衬线字体';
}
.ql-snow .ql-picker.ql-font .ql-picker-label[data-value=monospace]::before,
.ql-snow .ql-picker.ql-font .ql-picker-item[data-value=monospace]::before {
  content: '等宽字体';
}
.ql-toolbar.ql-snow + .ql-container.ql-snow {
  border-bottom-left-radius: 5px;
  border-bottom-right-radius: 5px;
}
.ql-toolbar.ql-snow {
  border-top-left-radius: 5px;
  border-top-right-radius: 5px;
}
.ql-snow .ql-stroke,
.ql-snow .ql-picker {
  color: #999;
  stroke: #999;
}
.ql-snow .ql-fill, .ql-snow .ql-stroke.ql-fill {
  fill: #999;
}
.ql-snow .ql-picker.ql-size .ql-picker-label[data-value='12px']::before, .ql-snow .ql-picker.ql-size .ql-picker-item[data-value='12px']::before {
  content: '12px';
}
.ql-snow .ql-picker.ql-size .ql-picker-label[data-value='14px']::before, .ql-snow .ql-picker.ql-size .ql-picker-item[data-value='14px']::before {
  content: '14px';
}
.ql-snow .ql-picker.ql-size .ql-picker-label[data-value='16px']::before, .ql-snow .ql-picker.ql-size .ql-picker-item[data-value='16px']::before {
  content: '16px';
}
.ql-snow .ql-picker.ql-size .ql-picker-label[data-value='20px']::before, .ql-snow .ql-picker.ql-size .ql-picker-item[data-value='20px']::before {
  content: '20px';
}
.ql-snow .ql-picker.ql-size .ql-picker-label[data-value='24px']::before, .ql-snow .ql-picker.ql-size .ql-picker-item[data-value='24px']::before {
  content: '24px';
}
.ql-snow .ql-picker.ql-size .ql-picker-label[data-value='36px']::before, .ql-snow .ql-picker.ql-size .ql-picker-item[data-value='36px']::before {
  content: '36px';
}
.ql-container {
  font-size:14px;
}

到这里我们富文本编辑器的字体就配置好了，下来我们配置插入图片上传七牛，并调整图片的大小。

1、导入需要的js

import { quillEditor } from 'vue-quill-editor'
import * as Quill from 'quill'
import { ImageDrop } from 'quill-image-drop-module'
import ImageResize from 'quill-image-resize-module'
Quill.register('modules/imageDrop', ImageDrop)
Quill.register('modules/imageResize', ImageResize)

2、配置build/webpack.dev.config/webpack.pro.config.js，plugins:[]中加入以下代码

new webpack.ProvidePlugin({
  'window.Quill': 'quill/dist/quill.js',
  'Quill': 'quill/dist/quill.js'
})

这样就可以调整图片尺寸了

接下来我们将图片上传到七牛服务器，并且将地址插入到富文本编辑器中。

1、我们监听点击富文本编辑器上面的图片被单击的时候，触发我们的上传组件被单击，打开上传窗口。

 mounted () {
    // 工具栏中的图片图标被单击的时候调用这个方法
    let imgHandler = (state) => {
      if (state) {
        document.querySelector('.avatar-uploader input').click()
      }
    }
    // 当工具栏中的图片图标被单击的时候
    this.$refs.myQuillEditor.quill.getModule('toolbar').addHandler('image', imgHandler)
  },

2、上传组件，上传图片到七牛，成功以后获取到上传图片的地址，插入到富文本编辑器中

<Upload
      class="avatar-uploader"
      :accept="'image/*'"
      :action="'https://upload.qiniup.com'"
      // 注意name必须是file，之前写的img，七牛老报错，说是multiple什么的name必须是file。
      name='file'
      :data="updateParams"
      :show-upload-list="false"
      :on-success="uploadSuccess"
      :on-error="uploadError"
      :before-upload="beforeUpload"
    >

3、这里:action是七牛服务器地址，我们需要在beforeUpload()钩子函数中传递两个参数（token：后台接口获取，key：文件名称），然后在successUpload()钩子函数中获取到上传图片地址，直接插入到富文本编辑器就可以了。

beforeUpload (request, file) {
      // 设置上传参数
      this.updateParams.token = this.$store.state.upload_token
      this.updateParams.key = request.name
    },

 uploadSuccess (res, file) {
      // file 返回的文件信息，也可以在这里调用七牛上传。
      console.log(res, file, this.$store.getters.upload_url + res.key, 'success')
      // 上传完成以后修改图片地址，回显到quill编辑器中
      let quill = this.$refs.myQuillEditor.quill
      let length = quill.getSelection() ? quill.getSelection().index : 0
      // 插入图片  res.info为服务器返回的图片地址
      console.log(this.$store.getters.upload_url + file.name)
      // quill.insertEmbed(length, 'image', this.$store.getters.upload_url + file.name)
      quill.insertEmbed(length, 'image', this.$store.getters.upload_url + res.key)
      // 调整光标到最后
      quill.setSelection(length + 1)
    },

这样就完成了vue + upload + quill 封装富文本编辑器组件的全过程，下面是我封装的组件的全部代码，token是在$store中保存的。

<template>
  <div id='quillEditorQiniu'>
    <quill-editor
      :style="{width: width ? width: '100%'}"
      v-model="content"
      ref="myQuillEditor"
      :options="editorOption"
      @change="onEditorChange($event)"
    >
    </quill-editor>
    <Upload
      class="avatar-uploader"
      :accept="'image/*'"
      :action="'https://upload.qiniup.com'"
      name='file'
      :data="updateParams"
      :show-upload-list="false"
      :on-success="uploadSuccess"
      :on-error="uploadError"
      :before-upload="beforeUpload"
    >
    </Upload>
  </div>
</template>
