需要引入的界面

//引入文件
import {
        formatRichText
    } from '../../utils/text.js'

//获取数据接口
async getActicle(){
                const mydata=await this.$myRequest({
                    url:"/api.php/grow/chengzhang_info",
                    method: 'POST',
                    data:{
                        id:25
                    }
                })

 //formatRichText 调用方法        
this.showaticle=formatRichText(mydata.data.data.this_info.content);
               
            },
//页面中显示
<rich-text :nodes="showaticle"></rich-text>
