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) } }
