我想创建一个程序来访问文件中的图像,对它们进行编码,然后将它们发送到服务器.比服务器应该解码图像,并将其保存到文件.我测试了图像编码本身,它工作,所以问题在于服务器和客户端连接.

这是服务器:

import socket
import errno
import base64

from PIL import Image
import StringIO

def connect(c):
    try:
        image = c.recv(8192)
        return image
    except IOError as e:
        if e.errno == errno.EWOULDBLOCK:
            connect(c)


def Main():
    host = '138.106.180.21'
    port = 12345

    s = socket.socket(socket.AF_INET, socket.SOCK_STREAM, socket.IPPROTO_TCP)
    s.setsockopt(socket.SOL_SOCKET,socket.SO_REUSEADDR,1)
    s.bind((host, port))
    s.listen(1)


    while True:

        c, addr = s.accept()
        c.setblocking(0)

        print "Connection from: " + str(addr)

        image = c.recv(8192)#connect(c)

        imgname = 'test.png'

        fh = open(imgname, "wb")
        if image == 'cusdom_image':
            with open('images.png', "rb") as imageFile: …

我想用Python制作服务器和客户端.它应该建立多个连接,一个是服务器向客户端发送内容,另一个是客户端向服务器发送内容的连接.

第一个连接工作正常,但第二个连接崩溃了消息:

socket.error: [Errno 9] Bad file descriptor

这是服务器:

import socket
import errno
import pickle

def Main():
    host = '188.174.233.99'
    port = 66666

    all_text = ['text1', 'text2', 'text3']

    all_description = ['Test \n Description1\n', 'Test \n Description1\n', 'Test \n Description1\n']

    all_images = ['unlock.png', 'unlock.png', 'unlock.png']
    s = socket.socket(socket.AF_INET, socket.SOCK_STREAM, socket.IPPROTO_TCP)
    s.bind((host, port))
    s.listen(1)


    while True:

        c, addr = s.accept()
        c.setblocking(0)

        print "Connection from: " + str(addr)


        command = c.recv(1024)

        if command == 'GIVEALL':
            textstring = pickle.dumps([all_text, all_images, all_description])#verwandelt Liste in String …
