再接再厲，再次使用python3學習編寫了一個爬取百度貼吧帖子的程式，不多說，直接上關鍵程式碼

#抓取貼吧一個帖子上的內容（一頁內容）
import urllib
import urllib.request
import re
page = 1
baseUrl = r'https://tieba.baidu.com/p/2687476192'
seeLZ = 0
try:
	url = baseUrl+'?see_lz='+str(seeLZ)+'&pn='+str(page)
	request = urllib.request.Request(url)
	response = urllib.request.urlopen(request)
	content = response.read().decode('utf-8')
	#獲取帖子標題
	patternTitle = re.compile(r'<h\d class="core_title_txt.*?>(.*?)</h\d>',re.S)
	resultTitle = re.search(patternTitle,content)
	print(resultTitle.group(1).strip())
	#獲取帖子回覆數和總頁數
	patternNum = re.compile(r'<li class="l_reply_num".*?><span.*?>(.*?)</span.*?<span.*?>(.*?)</span>',re.S)
	resultNum =re.search(patternNum,content)
	print(resultNum.group(1).strip(),resultNum.group(2).strip())
	#獲取帖子每層樓內容
	patternContent = re.compile(r'<div id="post_content_.*?">(.*?)</div>',re.S)
	items = re.findall(patternContent,content)
	tool = Tool()
	for item in items:
		print('\n',tool.replace(item),'\n')
except urllib.request.URLError as e:
	if hasattr(e,'reason'):
		print(e.reason)
