Question

大家好我想在我的项目中使用Multi downloader module。我检查了git链接，但没有关于如何使用此模块的示例。我检查了this link作为示例并在我的项目中使用，但它显示在错误之下。

createDownload is not a constructor

TypeError: createDownload is not a constructor

请从昨天开始帮助我，我正在寻找一些有用的例子，但我找不到它。

下面是我使用的代码并得到了错误

router.get('/downloadFile', function(req, res, next) {
    var createDownload = require('mt-downloader').createDownload
    var url = 'https://upload.wikimedia.org/wikipedia/commons/4/47/Gadget_the_pug_expressive_eyes.jpg';
    var path = '/Gadget_the_pug_expressive_eyes.jpg';
    var downloader = createDownload({path, url});
    downloader.start() // returns an observable
});

Answer 1

var createDownload = require('mt-downloader');
var url = 'https://upload.wikimedia.org/wikipedia/commons/4/47/Gadget_the_pug_expressive_eyes.jpg';
var path = '/Gadget_the_pug_expressive_eyes.jpg';
var dl=new createDownload();    
var downloader = dl.download(url,path);
downloader.start();

如何在节点中使用mt-downloader模块
