收到[错误数据] ..在Python中的Soket编程

Question

我很有趣的客户端发送消息到Python服务器。

客户端：client.send（ “1”） 服务器端：

d=clientsocket.recv(1024) 
if (d=="1"): 
    print(" Correct value") 

它不会打印正确的值。我知道recv的错误，因为我不知道它是如何工作的。任何人都可以请帮我解决这个问题。

你只需要简单的修改才能正常工作吧： -

在客户端正确象下面这样： -

client.send("1".encode()) 

在服务器正确象下面这样： -

d=clientsocket.recv(1024).decode() 
if (d=="1"): 
    print(" Correct value") 

我创建一个适合你的客户端和服务器，它在Python 3.4中工作正常。请尝试和检查：

这是你的服务器

import socket 
import sys 

HOST = "localhost" 
PORT = 8000 

print("Creating socket...") 
sc = socket.socket(socket.AF_INET, socket.SOCK_STREAM) 
print("Binding socket...") 
try: 
    sc.bind((HOST, PORT)) 
except socket.error as err: 
    print("Error binding socket, {}, {}".format(err[0], err[1])) 
print("bound Successful") 

# Configure below how many client you want that server can listen to simultaneously 
sc.listen(2) 
print("Server is listening on {}:{}".format(HOST, PORT)) 
while True: 
conn, addr = sc.accept() 
print("Connection from: " + str(addr)) 
print("Receiving data from client\n") 
data = conn.recv(1024).decode() 
print("Client says :" + data) 
if(data == "2"): 
    print(" Ooh you are killing me with value :" + data) 
    conn.sendall(str.encode("\n I am server and you killed me with :" + data)) 
    break; 
elif(data == "1"): 
    print(" Correct value :" + data) 
    conn.sendall(str.encode("\n I am server and you hit me with correct value:" + data)) 
else: 
    print(" You are sending a wrong value :" + data) 
    conn.sendall(str.encode("\n I am server and you hit me with wrong value :" + data)) 
sc.close() 

，现在你的客户是在这里： -

import socket 
import sys 

HOST = "localhost" 
PORT = 8000 
print("creating socket") 
sc = socket.socket(socket.AF_INET, socket.SOCK_STREAM) 
print("Connecting to host") 
try: 
    sc.connect((HOST, PORT)) 
except socket.error as err: 
    print("Error: could not connect to host, {}, {}".format(err[0], err[1])) 
    sys.exit() 
print("Connection established to host") 
message = "1" # Run client 3 times with value message = '1' and '5' and '2' 
sc.send(message.encode()) 
data = sc.recv(1024).decode() 
print("Server response is : " + data) 
sc.close()
