How to transfer document format in vue

With the popularity of modern web applications, the use of front-end frameworks has become more and more common, among which the vue framework has been widely used in the field of front-end development. In vue, it is often necessary to pass various types of data, including document formats. Next we will explore how to pass document formats in vue.

The first step in passing the document format is to construct the URL for the document. A URL is an address used to retrieve information from a web server and can transfer various file types to the client. In vue, we can use vue-router to manage the relationship between URLs and views to achieve document delivery. In vue-router, we can use routing parameters to dynamically build URLs.

For example, suppose we have a document list component that displays all documents on the server. We want to pass a URL pointing to a specific document to download. We can use routing parameters to build a URL:

<template>
  <div>
    <ul>
      <li v-for="doc in documentList" :key="doc.id">
        <router-link :to="{ name: &#39;document&#39;, params: { id: doc.id } }">
          {{ doc.title }}
        </router-link>
      </li>
    </ul>
  </div>
</template>

<script>
export default {
  name: 'DocumentList',
  data() {
    return {
      documentList: [
        {
          id: 1,
          title: 'Document 1',
          url: '/documents/1.docx',
        },
        {
          id: 2,
          title: 'Document 2',
          url: '/documents/2.pdf',
        },
      ],
    };
  },
};
</script>

In the above code, we use vue-router's routing parameter function to build a URL pointing to a specific document. This URL passes the ID of the document as a parameter, and then we can build the document to be returned based on this ID on the backend.

On the server side, we can use Node.js and Express to write routing handlers:

const express = require('express');
const router = express.Router();

router.get('/documents/:id', function (req, res) {
  const docId = req.params.id;
  // 根据ID查找文档
  res.download(`./documents/${docId}.docx`);
});

In the above code, we use the routing function of Express, which will have the document ID The request is mapped to the corresponding document path. Finally, we use Express's res.download method to send the document back to the client.

In vue, we can use the axios library to send requests to the backend and get the documents returned by the server. You can use the get method of axios to obtain the document on the server, and then use the download function of the browser to download the document.

<template>
  <div>
    <button @click="downloadDocument(documentUrl)">下载文档</button>
  </div>
</template>

<script>
import axios from 'axios';

export default {
  name: 'Document',
  data() {
    return {
      documentUrl: '',
    };
  },
  created() {
    const id = this.$route.params.id;
    axios.get(`/documents/${id}`).then((response) => {
      this.documentUrl = response.request.responseURL;
    });
  },
  methods: {
    downloadDocument(url) {
      window.location.href = url;
    },
  },
};
</script>

In the above code, we directly call the axios library in vue and use the get method to send a get request to the backend to obtain the document. Once we have the url of the document, we can open the document directly in the browser to download it.

Summary:

The best way to pass the document format in Vue is to first build the document url on the server, and then use axios in vue to get the document content from the server. The simplest way to download a document in Vue is to open the document URL directly in the browser using window.location.href.
