react实现导出文件，导出文件格式为json或excel格式

1.导出文件为json文件 

 下载 file-saver  模块 

import { saveAs } from 'file-saver';


注：data代表请求的数据 格式为[{},{},{}...]

//导出
  const handleExport = async () => {
    let { data } = await axios.get(`http://localhost:3000/leave`);
    console.log(data);
    const fileStream = JSON.stringify(data);
    const blob = new Blob([fileStream]);
    saveAs(blob, `表单.json`);
  };

2.导出为excel

 安装 xlsx

import * as XLSX from 'xlsx';
  const handleExport2 = async () => {
    let { data } = await axios.get(`http://localhost:3000/leave`);
    console.log(data);
    let sheet = XLSX.utils.json_to_sheet(data);
    let book = XLSX.utils.book_new();
    XLSX.utils.book_append_sheet(book, sheet, 'sheet1');
    XLSX.writeFile(book, `userlist${new Date().getTime()}.xls`);
  };
