Python笔记——socket2

#1、通过soket完成一个页面显示
import socket

body = "Hello world"
string = f"HTTP/1.1 200 ok\r\nContent-Length:{len(body)}\r\n\r\n{body}"
service = socket.socket()
service.bind(("127.0.0.1",23333))
service.listen(10)
client , IP = service.accept()
client.send(string.encode())

#2、通过Soket返回一个图片
import socket

fail = open(r"D:\学习\python\python高阶第02天网络原理\滑稽.jpg","rb").read()
body = fail
string = f"HTTP/1.1 200 ok\r\nContent-Length:{len(body)}\r\nSet-Cookie:login=true\r\n\r\n"
service = socket.socket()
service.bind(("127.0.0.1",23333))
service.listen(10)
client , IP = service.accept()
client.send(string.encode()+body)


#3、通过浏览器地址，访问不同的页面
import socket
import _thread

path = r"D:\学习\python\python高阶第02天网络原理\下午HTTP协议"
service = socket.socket()
service.bind(("127.0.0.1", 23333))
service.listen(10)
def run(client: socket.socket):
    s = client.recv(1024 * 1024)
    a = str(s.split("\r\n\r\n".encode())[0])
    head = a.split("\r\n")
    l = head[0].split(" ")
    l[1] = l[1].replace("/", r"\\")
    body = open(path + l[1], "rb").read()
    string = f"HTTP/1.1 200 ok\r\nContent-Length:{len(body)}\r\n\r\n"
    client.send(string.encode() + body)
    client.close()
while True:
    client, ip = service.accept()
    _thread.start_new_thread(run, (client,))


#4、写出一个登陆页面，实现一个登陆功能
import socket
import _thread

path = r"D:\学习\python\python高阶第02天网络原理\下午HTTP协议"
service = socket.socket()
service.bind(("127.0.0.1", 23333))
service.listen(10)
def login(d: dict):
    name = d["name"]
    password = d["password"]
    if name == "admin" and password == "admin":
        return "true"
    else:
        return "false"
def run(client: socket.socket):
    s = client.recv(1024 * 5)
    a = s.split("\r\n\r\n".encode())
    d = {
    
    }
    if len(a) > 1 and len(a[1]) > 0:
        a[1] = a[1].decode()
        lists = a[1].split("&")
        for i in lists:
            b = i.split("=")
            d[b[0]] = b[1]
    a = str(a[0])
    head = a.split("\r\n")
    l = head[0].split(" ")
    l1 = l[1].split("?")
    if len(l1) > 1:
        lists = l1[1].split("&")
        for i in lists:
            a = i.split("=")
            d[a[0]] = a[1]
    if l1[0] == "/login":
        c = login(d)
        body = c.encode()
    else:
        body = open(path + l1[0], "rb").read()
    string = f"HTTP/1.1 200 ok\r\nContent-Length:{len(body)}\r\nSet-Cookie:login=true\r\n\r\n"
    client.send(string.encode() + body)
    client.close()
while True:
    client, ip = service.accept()
    _thread.start_new_thread(run, (client,))


#5、在登陆功能的基础上，如果用户已经登陆，则返回已经登陆信息（cookie） 
import socket
import _thread

path = r"D:\学习\python\python高阶第02天网络原理\下午HTTP协议"
service = socket.socket()
service.bind(("127.0.0.1", 23333))
service.listen(10)
def login(d: dict):
    name = d["name"]
    password = d["password"]
    if name == "admin" and password == "admin":
        return "true"
    else:
        return "false"
def run(client: socket.socket):
    s = client.recv(1024 * 5)
    a = s.split("\r\n\r\n".encode())
    print(a)
    d = {
    
    }
    if len(a) > 1 and len(a[1]) > 0:
        a[1] = a[1].decode()
        print(a[1])
        lists = a[1].split("&")
        print(lists)
        for i in lists:
            b = i.split("=")
            print(b)
            d[b[0]] = b[1]
    a = str(a[0])
    head = a.split("\r\n")
    l_I = head[0].split("Cookie:")
    print(f"登录信息:{l_I[1]}")
    l = head[0].split(" ")
    l1 = l[1].split("?")
    if len(l1) > 1:
        lists = l1[1].split("&")
        for i in lists:
            a = i.split("=")
            d[a[0]] = a[1]
    if l1[0] == "/login":
        c = login(d)
        body = c.encode()
    else:
        body = open(path + l1[0], "rb").read()
    string = f"HTTP/1.1 200 ok\r\nContent-Length:{len(body)}\r\nSet-Cookie:login=true\r\n\r\n"
    client.send(string.encode() + body)
    client.close()
while True:
    client, ip = service.accept()
    _thread.start_new_thread(run, (client,))
