主要使用Python的urllib.request库来调用https://nlp.xiaoi.com/上的接口,具体接口可以通过浏览器抓包获取,然后根据抓包信息进行悉睁url的构造,使用urllib.request库的urlopen函数来调用构造的url,将其返回进行编解码之后,使培洞用re模块将所需信息匹配出来。
功能实现脚本如下:
因为工作养成的习惯睁中岁,生怕写的脚本在别的环境跑出问题,索性将它编译成exe文件。
使用pyinstall库来实现py脚本到exe文件的编译过程。
(本文参考csdn上的一篇文章,路径如下:https://blog.csdn.net/jiahuiandxuehui/article/details/118193844,不过这里的运行后返回结果会有一些\r\n这种东西,这里我修改了一下正则表达式,把不重要的信息给过滤掉了。)
python聊天室(python2.7版本):
暂时先给出两种版本的,tcp+udp
都是分别运行server.py和client.py,就可以进行通讯了。
别外还有websocket版本,这个是有web界面的和基本web服务的,如果需要的话,我会把基本的代码贴一版上来。
TCP版本:
socket-tcp-server.py(服务端):#-*- encoding:utf-8 -*-
#socket.getaddrinfo(host, port, family=0, socktype=0, proto=0, flags=0)
#根据给定的参数host/port,相应的转桥掘换成一个包含用于创建socket对象的五元组,
#参数host为域名,以字符串形式给出代表一个IPV4/IPV6地址或者None.
#参数port如果字符串形式就代表一个服务名,比如“http”"ftp""email"等,或者为数字,或者为None
#参数family为地主族,可以为AF_INET ,AF_INET6 ,AF_UNIX.
#参数socktype可以为SOCK_STREAM(TCP)或者SOCK_DGRAM(UDP)
#参数proto通常为0可以直接忽略
#参数flags为AI_*的组合,比如AI_NUMERICHOST,它会影响函数的返回值
#附注:给参数host,port传递None时建立在C基础,通过传递NULL。
#该函数返回一个五元组(family, socktype, proto, canonname, sockaddr),同时第五个参数sockaddr也是一个二元组(address, port)
#更多的方法及链接请访问
# Echo server program
