我希望获得google.com页面的html代码,但是我得到了这个符号>",这有什么问题呢?
I expect to get the html code of google.com page, but I get this sign ">", what the wrong with that ?
推荐答案
您需要调用read()方法来读取响应.同样好的做法是检查HTTP状态,并在完成后关闭.
You need to call the read() method to read the response. Also good practice to check the HTTP status, and close when your done.
示例:
url = "http://www.google.com/"
try:
response = urllib2.urlopen(url)
if response.code == 200:
html = response.read()
self.response.out.write(html)
else:
# handle
response.close()
except urllib2.URLError, e:
pass
