很久以前，python2的時候，簡單的弄過一點爬蟲程式，後來，到3之後，發現之前的好多程式都特麼不能用了，最最基本的抓頁面都不行了，就重新寫了乙個。
python2縮寫版，大概是這樣的，忘記了沒驗證
import urllib2
response = urllib2.urlopen('')
html = response.read()
print html
import urllib.request
request = urllib.request.request('')
response = urllib.request.urlopen(request)
if response.getcode() != 200:
print("none!")
else:
html = response.read()
# 如果返回結果不為空
if html is
notnone:
# 還必須編碼，不然格式不對
html = html.decode("utf-8")
print(html)
else:
print("maybe the program is error!")
# 頭資訊
print(response.info())
