从 nodejs 压缩和下载

Question

我正在尝试使用 easy-zip 模块压缩文件并从服务器下载。但是现在我可以使用下面的代码写入服务器，但是我怎样才能让它可以下载呢？？？

var app = require('express')();
var easyzip = require('easy-zip');

app.get('/api/downloadFile',function(req,res){
    console.log("inside req");
    var data = "<html><body><h1>Inside new Html</h1></body></html>";
    var zip2 = new easyzip.EasyZip();
    var jsFolder = zip2.folder('data');
    jsFolder.file('app.js','alert("hello world")');
    jsFolder.file('index.html',data);
    zip2.writeToFile('folder.zip');
});

Answer 1

尝试 zip2.writeToResponse(res,'folder.zip'); 而不是 zip2.writeToFile('folder.zip');

Answer 2

而不是写入文件写入响应

var app = require('express')();
var easyzip = require('easy-zip');

app.get('/api/downloadFile',function(req,res){
    console.log("inside req");
    var data = "<html><body><h1>Inside new Html</h1></body></html>";
    var zip2 = new easyzip.EasyZip();
    var jsFolder = zip2.folder('data');
    jsFolder.file('app.js','alert("hello world")');
    jsFolder.file('index.html',data);
    zip2.writeToResponse(res,'folder');
    res.end();
})
