python获取豆瓣日记

最近迷上了看了四个春天，迷上了饭叔的豆瓣日记，想全部抓取下来，简单了写了下面的脚本

import urllib.request
import os

from bs4 import BeautifulSoup


def get_html(url):
    """通用方法，获取整个链接得html·"""
    web = urllib.request.urlopen(url)
    soup = BeautifulSoup(web, "html.parser")
    # print(soup)
    data = soup.find("div", id="content")
    return data


def get_diary(data,path):
    """获取日记链接，并且存储起来"""
    data = data.find_all("div",class_="note-header-container")
    for link in data:
        # print(link)
        diary_url = link.find('div', class_="rr").find('a').get("href")
        with open(path, 'a+', encoding='UTF-8') as f:
            f.write(diary_url+'
')


def get_num(url):
    #获取最大页数
    html_data = get_html(url)
    paginator_data = html_data.find("div",class_="paginator")
    page_num =[]
    for link in  paginator_data.find_all("a"):
        page_num.append(link.get_text())


    return "".join(page_num[-2:-1])

def get_diary_data(url,path):
    """获取日记内容，保存为txt文件"""
    data = get_html(url)
    title = data.find("h1").get_text()
    file_name = path+"/"+title+".txt"
    with open(file_name,'a+',encoding='UTF-8') as f:
        f.write(title)
    note_data = data.find("div",id="link-report")
    for node_line in note_data.stripped_strings:
        with open(file_name, 'a+', encoding='UTF-8') as f:
            f.write(repr(node_line))



if __name__ == '__main__':
    url = 'https://www.douban.com/people/luqy/notes'
    path = "d://陆导"
    diary_url_path = path + "/"+"diary_url.txt"
    page_num = get_num(url)
    for i in range(14):
        url1 = url + "?start=%d&type=note"%(i*10)
        get_diary(get_html(url1),diary_url_path)

    f = open(diary_url_path,'r',encoding='utf-8')
    for line in f.readlines():
        try:
            get_diary_data(line,path)
        except Exception as e:
            print(e)
    f.close()

目前存在一个问题

1，抓取次数过多会被分IP地址
