这篇是Bigway同学的投稿,一个用py实现wp自动发文的小脚本
解决思路
1、利用post向wordpress提交表单2、通过wordpress_xmlrpc模块,有轮子不用想干啥3、通过mysqldb直接插入数据库,有服务器、不需远程,直接把py脚本放在服务器跑
我们这次要用轮子拼一台摩托车!,宝马、、自己动手吧
开始动手:
需自行安装的模块requests,xmlrpc;windows系统、linux安装如下,土豪随意:
pip install requests
pip install python-wordpress-xmlrpc
caiji.py
#encoding=utf-8
'''练手可以找wp博客来采集,这个脚本就是针对wp博客来做下手采集的'''
import re,requests,time,random,urllib,threading
from wordpress_xmlrpc import Client, WordPressPost
from wordpress_xmlrpc.methods.posts import GetPosts, NewPost
'''登录'''
try:
wp=Client('http://www.example.com/xmlrpc.php','wp的账号','wp的密码')
except Exception, e:
wp=Client('http://www.example.com/xmlrpc.php','wp的账号','wp的密码')
post=WordPressPost()
'''针对单站url重复采集问题'''
f=open('url.txt','a+')
urls=f.read()
url_list=[m.strip() for m in open('url.txt').readlines()]
daili_list=[]
'''过滤html标签'''
def filter_tags(htmlstr):
re_cdata=re.compile('//<!\[CDATA\[[^>]*//\]\]>',re.I) #匹配CDATA
re_script=re.compile('<\s*script[^>]*>[^<]*<\s*/\s*script\s*>',re.I)#Script
re_style=re.compile('<\s*style[^>]*>[^<]*<\s*/\s*style\s*>',re.I)#style re_br=re.compile('<br\s*?/?>')#处理换行
re_br=re.compile('<br />')
re_h=re.compile('</?\w+[^>]*>')#HTML标签
re_comment=re.compile('<!--[^>]*-->')#HTML注释
s=re_cdata.sub('',htmlstr)#去掉CDATA
s=re_script.sub('',s) #去掉SCRIPT
s=re_style.sub('',s)#去掉style
s=re_br.sub('\n',s)#将br转换为换行
s=re_h.sub('',s) #去掉HTML 标签
s=re_comment.sub('',s)#去掉HTML注释
blank_line=re.compile('\n+')#去掉多余的空行
s=blank_line.sub('\n',s)
return s
'''轮换user-agent'''

'''提取正则'''

'''轮换ip'''

'''将列表页放到list的数据类型当中'''
url_list = []
for line in range(1,15):
line = 'http://www.example.com/page/%d'%line
word = line.strip()
url_list.append(word)
'''多线程'''
totalThread = 5
gap = (len(url_list) - 1) / totalThread
mutex = threading.Lock()
for i in range(1, len(url_list),gap):
t = threading.Thread(target=getRange,args=(i, i+gap,))
t.start()
f.close()
设置采集内容到哪个默认目录,可以在wp后台设置,从代码上做修改也可以;
具体可以看看xmlrpc官方文档:http://python-wordpress-xmlrpc.readthedocs.io/en/latest/overview.html
另外可以通过命令crontab -e 让脚本按需自动跑起来!
