mammoth.convertToHtml(input, options） ：把源文档转换为 HTML 文档
mammoth.convertToMarkdown(input, options) ：把源文档转换为 Markdown 文档。
mammoth.extractRawText(input) ：提取文档的原始文本。这将忽略文档中的所有格式。每个段落后跟两个换行符。

 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})
}
