尝试使用Urllib打开页面时出错。 （python3）

Question

我在抓取时循环浏览一组页面，但是特定的页面不断出现错误，尽管其他页面工作正常。

为了测试有问题的页面，我写了：

class AppURLopener(uReq.FancyURLopener):
    version = "Mozilla/5.0"

url = 'http://snesguide.com/genre/beatemup/2'
opener = AppURLopener()


try:
    page_html = opener.open(url).read()
except:
    print("Error loading webpage")

url = 'http://snesguide.com/genre/beatemup/1'有效

url = 'http://snesguide.com/genre/beatemup/3'也可以

url = 'http://snesguide.com/genre/beatemup/2'引发以下内容：

（我应该提到这三个功能都可以在浏览器中使用！）

有什么想法吗？
