python webpy purge nginx fastcgi cache 代码实现，webpynginx,前几天写了一下 ngin

前几天写了一下 nginx + webpy + fastcgi cache 配置详解，光配置还是不够的，启用缓存之后还需要purge缓存，今天分享下如何使用python来purge nginx的缓存。

#!/usr/bin/env python# coding: utf-8import socketfrom config import configParser,loggerimport refrom urlparse import urlparse__author__ = 'byrx.net'purgeHost = 'byrx.net'purgeIP = '127.0.0.1'purgePort = 80def purge(url):    urlParts = urlparse(url)    page = '%s%s%s' % (urlParts.path, ('?' if urlParts.query else ''), urlParts.query or '')    s = None    try:        logger.info('purge %s' %(url,))        s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)        s.connect((purgeIP, purgePort))        s.send('GET /purge/' + page +' HTTP/1.1\nHost:' + purgeHost + '\n\n')        data = s.recv(1024)        ###检查是否有“404 Not Found” 或 "Successful purge" 字符串        success = "Successful purge"        found = "404 Not Found"        if re.search(success,data):            #purge success            return 0        elif re.search(found,data):            #print "该页面没有被缓存<br>"            return 1        else:            #print "未知错误...<br>"            logger.error('nginx purge url response:%s' % (data,))            return -1    except Exception,ex:        logger.error('nginx purge error : %s' % (ex,))        return -1    finally:        if s: s.close()

这段代码使用socket来purge缓存，需要指定连接的IP和端口。这是因为在配置时指定了允许访问的IP地址，其他地址拒绝访问。
