1.说明
之前写的博客都在csdn和博客园中
要将博客同步到自己的博客网站中
因为都是使用markdown格式书写的,所以直接爬取上传就完事
2.思路
分析了下博客园,发现可行。先登录进入自己的博客主页,可以看到有下一页的标志,每一页包含若干个博客详情,博客详情中包含edit页(编辑页面)和正常页面(其他用户访问的),要获取的就是eidt页面的博客名字,博客内容。博客分类在edit页面中不好获取,转而去正常页面获取,发现是一个ajax请求,传入用户id和博客id就可以获取到分类。信息获取到了就保存在本地,按分类保存。保存后就使用post请求发送到自己的博客网站中,或者直接写入数据库
3.代码
从文件读取请求头字典,构造函数传入的是文件名
class getHeaders(object):
def __init__(self,path):
self.dict_ = {}
with open(path, "r",encoding="utf8") as f:
line = f.readline()
while line:
a = line.split(":")
self.clean_(a)
try:
self.dict_[a[0]] = a[1]
except:
pass
line = f.readline()
def clean_(self,list_):
for i in range(len(list_)):
list_[i] = list_[i].strip()
if len(list_) > 2 :#说明有多个:号
try:
#开头为空,说明元字符串开头有:
list_.remove("")
list_[0] = ":"+list_[0]
except:
#说明开头不为空
list_[1] = list_[1]+":"+list_[2]
爬博客园的代码
import requests
from lxml import etree
from GetHeaders import getHeaders
import os
#博客园获取分类,传入ID
catagory_url = "https://www.cnblogs.com/simon-idea/ajax/CategoriesTags.aspx?blogId=xxxxxx&postId=%s"
#每一页中包含的url
link_list = []
#筛选详情页的url
detail_list = []
heads = getHeaders("博客园").dict_
for i in range(1,9):
url = "https://www.cnblogs.com/simon-idea/default.html?page=%s" #7
url = url % str(i)
req = requests.get(url, headers=heads)
html = etree.HTML(req.content)
every_page_links = html.xpath('//*[@id="mainContent"]/div/div/div/a/@href')
link_list.extend(every_page_links)
for i in link_list:
if "Edit" in i :
detail_list.append(i)
# assert 1 ==2
for i in detail_list:
url = i
req = requests.get(url, headers=heads)
a = req.content.decode(req.encoding)
html = etree.HTML(a)
# title //*[@id="Editor_Edit_txbTitle"]/@value
title = html.xpath('//*[@id="Editor_Edit_txbTitle"]/@value')[0]
# body //*[@id="Editor_Edit_EditorBody"]
body = html.xpath('//*[@id="Editor_Edit_EditorBody"]/text()')[0]
req = requests.get(catagory_url % i[-8:], headers=heads)
a = req.content.decode(req.encoding)
html = etree.HTML(a)
catagory = html.xpath('//*[@id="BlogPostCategory"]/a/text()')[0]
dirs = '博客/%s' % catagory
if not os.path.exists(dirs):
os.makedirs(dirs)
with open("博客/%s/%s.md" % (catagory,title),"w",encoding="utf-8") as f:
f.write(body)
上传的代码有很多坑,不完善
因为原博客作者的博客路径定义的有问题
