python自动发布文章到wordpress

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,threadpool
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'''

'''正则用以提取列表页上的url,需根据实际情况来调整'''

def now_time(url):
    for i in url_list:
        getData(i)

url_list = []
for line in range(1,12):
    line = 'http://www.example.com/page/%d'%line
    word = line.strip()
    url_list.append(word)

mutex = threading.Lock()
pool = threadpool.ThreadPool(3)
reqs = threadpool.makeRequests(now_time, url_list)
[pool.putRequest(req) for req in reqs]
pool.wait()

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!
