A weird problem: get 404 page by read method

[winglight]

Here's the url: http://www.8wenku.com/book/2414

I tried to open this page by postman or browser those are normal web page, but I got a 404 page after the read method callback return the article.

The code is followed here:

read(url, {strictSSL: false, headers: {
                    'User-Agent': 'Mozilla/5.0 (Macintosh; Intel Mac OS X 10_13_6) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/69.0.3497.100 Safari/537.36'
                }},function(err, article, meta) {
                if (!err) {
                    //article.content or article.html display a 404 page here

                    // Close article to clean up jsdom and prevent leaks
                    article.close();
                } else {
                    console.log("crawlTopic read error: " + err);
                    callback(err);
                }

            });
