1. 使用vue-office

父组件调用init方法即，适用于远程url和本地文件

npm install @vue-office/docx vue-demi

<template>
  <el-dialog
    v-el-drag-dialog
    :visible.sync="previewOpen"
    :close-on-click-modal="false"
    append-to-body
    custom-class="previewDialog"
    @close="closeDialog"
  >
    <vue-office-docx :src="docx" @rendered="rendered" />
  </el-dialog>
</template>
<script>
  import VueOfficeDocx from '@vue-office/docx'
  import axios from 'axios'
  export default {
    components: {
      VueOfficeDocx
    },
    data() {
      return {
        previewOpen: false,
        docx: '' // 远程url地址，本次使用blob文件流转url
      }
    },
    beforeDestroy() {
      if (this.docx) {
        URL.revokeObjectURL(this.docx) // 清除Blob URL
      }
    },
    methods: {
      // 预览
      init(id) {
        axios({
          method: 'get',
          responseType: 'blob',
          url: '' // 自己的服务器，提供的一个word下载文件接口
        }).then((res) => {
          this.previewOpen = true
          this.$nextTick(() => {
            this.docx = window.URL.createObjectURL(res.data)
          })
        })
      },
      rendered() {
        console.log('渲染完成')
      },
      closeDialog() {
        this.previewOpen = false
      }
    }
  }
</script>
<style scoped>
  .previewDialog .el-dialog__headerbtn .el-dialog__close {
    z-index: 2001;
  }
  .word {
    display: block;
  }
</style>

2.使用docx-preview

父组件调用init方法即可，适用于本地文件

npm install docx-preview

<template>
  <el-dialog
    v-el-drag-dialog
    :visible.sync="previewOpen"
    :close-on-click-modal="false"
    append-to-body
    custom-class="previewDialog"
    @close="closeDialog"
  >
    <div class="word">
      <div ref="myfile" />
    </div>
  </el-dialog>
</template>
<script>
  const docx = require('docx-preview')
  import axios from 'axios'
  export default {
    data() {
      return {
        previewOpen: false
      }
    },
    methods: {
      init(id) {
        axios({
          method: 'get',
          responseType: 'blob',
          url: '' // 自己的服务器，提供的一个word下载文件接口
        }).then((res) => {
          this.previewOpen = true
          this.$nextTick(() => {
            docx.renderAsync(res.data, this.$refs.myfile)
          })
        })
      },
      closeDialog() {
        this.previewOpen = false
      }
    }
  }
</script>
<style scoped>
  .previewDialog .el-dialog__headerbtn .el-dialog__close {
    z-index: 2001;
  }
  .word {
    display: block;
  }
</style>
