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)
}
}
