javascript - 生成 PDF 和 Excel 工作表，但在 Excel 中它既不打开也不选择保存....(就像在 Laravel 中一样)

Question

如何在node js中生成excel表格直接打开或保存在系统中，而不是保存在项目目录中。

For Excel 
exports.excel = function (req, res) {
    var fs =require('fs');
    var excel = require('excel4node');
    var workbook = new excel.Workbook();
    var worksheet = workbook.addWorksheet('Sheet 1');
    var worksheet2 = workbook.addWorksheet('Sheet 2');
    worksheet.cell(1, 1).string('content for display');
    workbook.write('report.xlsx');
    workbook.co(function(ok){
        if (!ok) 
            workbook.cancel();
        else
            console.log('congratulations, your workbook created');
    });
    //res.download();
    //workbook.close();
    //res.redirect('/invoice/list');

};

Answer 1

如果您想流式传输 report.xlsx 的内容到网络浏览器，那么您需要在 console.log('congratulations, your workbook created') 之后添加以下行:

var filePath = path.join(__dirname, 'report.xlsx');
var stat = fs.statSync(filePath);
var ct = 'application/vnd.openxmlformats-officedocument.spreadsheetml.sheet';

res.writeHead(200, {
    'Content-Type': ct,
    'Content-Length': stat.size
});

var readStream = fs.createReadStream(filePath);
readStream.pipe(res);
