Question

我正在尝试将一些数据发布到网址，但我正在运行一个对我没有任何意义的python错误。

这是错误：

IndexError: list index out of range

这会导致上述错误：

request = urllib2.Request("http://google.com/foo/", headers={"Accept" : "text/html"})
contents = urllib2.urlopen(request).read()

这不会导致上述错误。唯一的区别是网址：

request = urllib2.Request("http://google.com/", headers={"Accept" : "text/html"})
contents = urllib2.urlopen(request).read()

所以问题似乎是域名之后的任何问题。有什么想法吗？

Answer 1

我能够通过使用urllib而不是urllib2让我的问题消失。我仍然不知道是什么原因引起了这个问题，但这次训练很好。

url = 'http://google.com/'
f = urllib.urlopen(url, params)

UnicodeDecodeError：'ascii'编解码器不能用urllib2 urlopen（）解码字节XX
