如何使用 Vue.js 读取 JSON 文件

在 Vue.js 中读取 JSON 文件主要有两种方法:使用 HTTP 请求或直接使用本地文件。

使用 HTTP 请求

要使用 HTTP 请求读取 JSON 文件,可以使用 axios 库:

import axios from 'axios'

export default {
  methods: {
    readJSON() {
      axios.get('path/to/json/file.json')
        .then((response) => {
          // 处理读取到的 JSON 数据
        })
        .catch((error) => {
          // 处理错误
        })
    }
  }
}

使用本地文件

对于本地 JSON 文件,可以使用 require 函数:

export default {
  methods: {
    readJSON() {
      const json = require('path/to/json/file.json')

      // 处理读取到的 JSON 数据
    }
  }
}

注意事项

  • 跨域问题:如果 JSON 文件托管在其他域上,在使用 HTTP 请求时需要考虑跨域问题。
  • 文件路径:指定 JSON 文件路径时,确保路径正确无误。
  • 数据格式:读取到的 JSON 数据是 JavaScript 对象,可以使用点表示法或方括号表示法访问其属性。
  • 错误处理:在使用 HTTP 请求时,务必处理可能发生的错误。
