Question

我需要多次从套接字读取。因为我需要在2秒内回复，所以读取应该是有效的，当我需要读取超过12,000整数的行时（用这些整数完成的计算不需要很长时间，即{{1} }）

我有以下方法：

0.015s

这可以更有效地完成，这样它不会花费2秒钟的时间来响应吗？

编辑：输入如下所示：

import socket

host = "SOMEHOST"
port = SOMEPORT

client = socket.socket(socket.AF_INET, socket.SOCK_STREAM)

client.connect((host, port))

def read_from_socket(client):
    response = ''
    char = ''
    while not '\n' in char:
        char = client.recv(1)
        response += char

    return response

for SOMEWHILE:
    line = read_from_socket(client)
    # do some stuff with line
    client.send(SOMEANSWER)

我已根据以下评论修改了代码：

Case #SOME_NUMBER:
T N
N numbers

我得到以下输出：

def read_from_socket(client, size=1):
    if size > 1:
        return client.recv(size*4)
    else:
        response = ''
        char = ''

        while not '\n' in char:
            char = client.recv(size)
            response += char

        return response

for i in SOME_RANGE:

    case = read_from_socket(client)
    print case
    T, N = read_from_socket(client).split(' ')
    numbers = read_from_socket(client, int(N)).split(' ')   
    numbers = filter(None, numbers)
    numbers = [int(number) for number in numbers]

    answer = # DO SOME STUFF WITH numbers

    print "{}".format(answer)

在最后一种情况下，Case #1: 4 Case #2: 1 Case #3: 3 Case #4: 6 Case #5: 5 Case #6: 6 17 14 5 13 6 1 18 15 3 7 3 4 2 15 3 11 13 13 19 17 15 11 4 6 13 16 20 1 9 13 12 5 19 8 10 16 1 7 2 3 14 5 7 7 19 1 10 4 13 20 12 20 10 15 5 14 11 17 14 11 1 17 15 11 5 16 7 5 3 8 19 8 4 5 6 3 18 15 18 10 6 9 9 16 4 6 9 6 14 15 16 6 11 2 17 7 18 3 3 12 2 2 11 6 18 16 20 15 3 17 17 8 5 5 15 20 2 16 17 7 10 4 13 12 6 9 19 15 3 1 18 16 14 8 1 12 15 12 18 9 8 14 9 5 11 3 4 12 18 13 11 19 16 3 11 13 3 1 19 17 13 16 12 7 15 5 10 2 16 19 10 16 13 18 20 3 13 15 6 10 7 8 1 3 10 3 7 4 3 6 20 15 1 12 13 8 8 14 9 3 13 10 10 5 8 9 19 12 4 16 13 10 4 13 4 5 15 11 9 17 16 20 4 8 3 8 7 10 2 15 5 14 17 14 18 16 15 8 Traceback (most recent call last): File "numbers.py", line 143, in <module> numbers = read_from_socket(client, int(N)).split(' ') ValueError: invalid literal for int() with base 10: '#7:\n'。据我所知，N = 2400可能大于12,000
