 npm install element-ui mammoth     插件

主要内容：

// 进行解析
const type = file.name.substring(file.name.lastIndexOf('.') + 1)   // 获取到的是文件类型
const reader = new FileReader()
reader.readAsArrayBuffer(file)
reader.onload = e => {const data = reader.resultmammoth.convertToHtml({ arrayBuffer: data }).then(r => {this.uploadListflow = r.value  // 获取到解析出来的内容})
}
