react项目中 使用react-draft-wysiwyg这个富文本组件，因为公司项目图片都是上传到阿里云oss服务器上，废话不说上代码，代码如下：
// 安装组件
yarn add react-draft-wysiwyg draftjs-to-html html-to-draftjs draft-js js-md5 axios
或者用npm install ** 来安装
// 引用组件
import axios from 'axios';
import {EditorState, convertToRaw, ContentState} from 'draft-js';
import 'react-draft-wysiwyg/dist/react-draft-wysiwyg.css';
import{Editor} from 'react-draft-wysiwyg';
import draftToHtml from 'draftjs-to-html';
import htmlToDraft from 'html-to-draftjs';
import md5 from 'js-md5';
export default class Wysiwyg extends Component{
constructor(props) {
super(props);
// 编辑器里的默认值
const html = '<p>Hey this <strong>editor</strong> rocks 😀</p>';
const contentBlock = htmlToDraft(html);
if (contentBlock) {
const contentState = ContentState.createFromBlockArray(contentBlock.contentBlocks);
const editorState = EditorState.createWithContent(contentState);
this.state = {
editorState,
};
}
}
componentWillMount(){
axios({
url: '**/frontend_sts_token', //后台接口的链接，主要返回上传到oss要用到的key, accesskeyid等
method: 'GET',
timeout: 4000,
headers: {
'content-type': 'application/json',
'Authorization': "Bearer token" //用到的token是从后台获取到, 这看后端要怎么传给他们，
},
params: ''
}).then((response)=>{
console.log(response.data.data)
this.setState({
frontend_sts_token: response.data.data
})
})
}
//编辑器输入方法
onEditorStateChange = Function = (editorState)=>{
this.setState({
editorState
})
}
//图片上传到oss的方法
uploadImageCallBack = Function = (file)=>{
console.log(file)
const {frontend_sts_token} = this.state;
return new Promise((resolve, reject) => {
let name = md5(file.name) +".jpg"; //生成md5文件名
let formData = new FormData();
let _key = frontend_sts_token.dir + name;
// 文件名字，可设置路径
console.log(_key)
formData.append('key', frontend_sts_token.dir + name);
// policy规定了请求的表单域的合法性
formData.append('policy', frontend_sts_token.policy)
// Bucket 拥有者的Access Key Id
formData.append('OSSAccessKeyId', frontend_sts_token.accessid)
// 让服务端返回200,不然，默认会返回204
formData.append('success_action_status', '200')
// 根据Access Key Secret和policy计算的签名信息，OSS验证该签名信息从而验证该Post请求的合法性
formData.append('callback', frontend_sts_token.callback)
formData.append('signature', frontend_sts_token.signature)
formData.append('name', name)
formData.append('file', file)
console.log(formData)

headers: { 'Content-Type': 'multipart/form-data' } ,
// 或者
// headers: {

})
.then((res) => {
console.log(res)
//添加到虚线框
let imgurl = res.data.filename;
let imgObj = {

}
}
resolve(imgObj)
