socketserver模块三次登陆验证,身份验证

帅爆太阳的男人

1,socketserver是解决TCP服务器和多个客户端进行通信

• 服务器:

import socketserver

class MySocket(socketserver,BaseRequestHandle):  # 里边的参数也是固定的,不用改变
    def handle(self):  # 方法的名字时固定的,必须是这个名字
        msg = self.request.recv(1024).decode("utf-8")
        print(msg)
        self.request.send(msg.upper().encode("utf-8"))

# 号里的两个参数第一个是地址,第二个是类名(增加一个线程)
server = socketserver.ThreadingTCPServer(("127.0.0.1",8001),Mysocket)
server.ser_forver()  # 开启一个永久性的服务

• 客户端:

import socket

sk = socket.socket()
sk.connect(("127.0.0.1",8001))
msg_s = input(">>>")
sk.send(msg_s.encode("utf-8"))
print(sk.recv(1024).decode("utf-8"))
sk.close()

2,三次登录验证:

• client:

import socket
import hashlib
import json
sk = socket.socket()
sk.connect(("127.0.0.1",8080))
dic = {"status":False,"username":username,"password":None}
c = 3
while c:
    username = input("请输入用户名:")
    password = input("请输入密码:")
    md5_obj = hashlib.md5(password.encode("utf-8"))
    md5_obj.update(username.encode("utf-8"))
    pawd_m = md5_obj.hexdigest()
    dic["username"] = username
    dic["password"] = pawd_m
    str_dic = json.dumps(dic)
    sk.send(str_dic.encode("utf-8"))
    res_dic = sk.recv(1024).decode("utf-8")
    result = json.loads(res_dic)
    if result["status"]:
        print("登录成功")
    else:
        print("失败, %s" % result["reason"])
    c = c - 1
    sk.close()

• 服务器

import socketserver
import json
import hashlib

def zhuce():
    pass

class MySocket(socketserver.BaseRequestHandler):
    def handle(self):
        sor = b"wusir"
        while 1:
            str_dic = self.request.recv(1024).decode("utf-8")
            if not str_dic:
                break
            dic = json.loads(str_dic)
            if not dic["status"]:
                with open("info", "r", encoding="utf-8") as f:
                    for info in f:
                        username, pawd_txt = info.strip().split("|")
                        if username == dic["username"]:
                            md5_obj = hashlib.md5(sor)
                            md5_obj.update(dic["password"].encode("utf-8"))
                            pawd = md5_obj.hexdigest()
                            if pawd_txt == pawd:
                                dic["status"] = True
                            else:
                                dic["reason"] = "密码错误"
                                break
                        else:
                            dic["reason"] = "用户不存在"
                            zhuce()
                            str_dic = json.dumps(dic)
                            self.request.send(str_dic.encode("utf-8"))
                    else:
                        self.request.send("已经登录成功".encode("utf-8"))

server = socketserver.TCPServer(("127.0.0.1", 8080), MySocket)

server.serve_forever()

3,进度条

import time  # 导入时间模块
for i in range(51):  # 因为每次输出的是每个循环数乘以2,所以要达成100%,所以循环遍历50就可以了
    time.sleep(0.12)  # 每当循环出一个数就成序就在这休眠0.12秒
    print("\r" + i * "=" + ">" + str(i * 2) + "%", end="")  # 固定写法(\r之前的内容不管是什么都不会输出)
