Python3 X 抓取網路資源

python 3.x 要使用urllib.request 來抓取網路資源。

最簡單的方式：

#coding=utf-8

import urllib.request
response = urllib.request.urlopen('')
buff = response.read()
#顯示html = buff.decode("utf8")
response.close()
print(html)

#coding=utf-8

import urllib.request
req = urllib.request.request('')
response = urllib.request.urlopen(req)
buff = response.read()
#顯示the_page = buff.decode("utf8")
response.close()
print(the_page)

#coding=utf-8

import urllib.request
req = urllib.request.request('')
response = urllib.request.urlopen(req)
buff = response.read()
#顯示the_page = buff.decode("utf8")
response.close()
print(the_page)

import urllib.parseimport

urllib.requesturl = ''
values = 
data = urllib.parse.urlencode(values)
req = urllib.request.request(url, data)
response = urllib.request.urlopen(req)
the_page = response.read()

import urllib.request

import urllib.parse
data = {}
data['name'] = 'somebody
here'
data['location'] = 'northampton'
data['language'] = 'python'
url_values = urllib.parse.urlencode(data)
print(url_values)
name=somebody+here&language=python&location=northampton
url = ''
full_url = url + '?' + url_values
data = urllib.request.open(full_url)

import urllib.parse

import urllib.request
url =
''user_agent =
'mozilla/4.0 (compatible; msie 5.5; windows nt)'
values = 
headers = 
data
= urllib.parse.urlencode(values)
req = urllib.request.request(url, data, headers)
response = urllib.request.urlopen(req)
the_page = response.read()

req = urllib.request.request('')

try: urllib.request.urlopen(req)
except urllib.error.urlerror as e:
print(e.reason)

Python3 x編碼問題

1.記事本的ansi編碼為系統本地編碼，我的是gbk open 函式的encoding引數預設是本地編碼，也就是gbk，所以直接讀取ansi編碼的記事本檔案是木有問題的。怎麼檢視系統本地編碼？在cmd下輸入 chcp 從下表可以看出，936對應gbk編碼 下表列出了所有支援的 頁及其國家 地區 或者...
