Question

我想构建一个服务器套接字并向客户端发送一行，客户端将打印该行

但是当我打印从服务器套接字接收的数据时，只打印文件的第一行，其他人则错过了

我注意到有时数据仍然会在“\ n”后面有数据所以我添加了以下两行代码，它会显示错误“substring not found” 但有时客户端会收到这种数据“5000 \ n1000”，所以客户需要保留1000 ...

remain = data[data.index("\n")+1:]
data = remain

这是我要发送给客户的数据

1000 2000 3000 4000 5000
1000 3000 5000 7000 9000
1111 2222 3333 4444 5555

服务器

import socket

Input = open("./Data","r")
data = Input.read()
Input.close()

# Construct the server_socket
server_sock = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
server_sock.bind(('localhost',15000))
server_sock.listen(1)
(client_socket,address) = server_sock.accept()

# send data
for line in data:
    client_socket.send(line)

client_socket.send("EOF")
client_socket.close()
server_sock.close()

客户端

import socket

client_sock = socket.socket(socket.AF_INET,socket.SOCK_STREAM)
client_sock.connect(('localhost',15000))

data = ""
while True:
    part = client_sock.recv(100)
    data = data + part
    if "\n" in data or "EOF" in data:
        list = data[:data.index("\n")].split(" ")
        print(list)
        remain = data[data.index("\n")+1:]
        data = remain
        if "EOF" in data:
            break

client_sock.close()
result.close()

Answer 1

我认为你需要缩进

client_socket.send(line)

Answer 2

我认为你真正想要的是：

Input.readLines()

套接字传输中的数据丢失
