我有一个问题,我创建了多处理服务器,但是当我发送numpy数组时,我的客户端在无限循环中运行,这是我的代码:
服务器: 我认为我的服务器代码很好。
import socket, pickle
import numpy as np
from PIL import ImageGrab
import cv2
import logging
import multiprocessing
def handle(connection, address):
logging.basicConfig(level=logging.DEBUG)
logger = logging.getLogger("process-%r" % (address,))
try:
logger.debug("Connected %r at %r", connection, address)
while True:
data = connection.recv(1024)
printscreen_pil=ImageGrab.grab(bbox=(10,10,500,500))
img = np.array(printscreen_pil) ## Transform to Array
data_string = pickle.dumps(img)
if data == "":
logger.debug("Socket closed remotely")
break
logger.debug("Received data %r", data)
connection.sendall(data_string)
logger.debug("Sent data")
except:
logger.exception("Problem handling request")
finally:
logger.debug("Closing socket")
connection.close()
class Server(object):
def __init__(self, hostname, port):
self.logger = logging.getLogger("server")
self.hostname = hostname
self.port = port
def start(self):
self.logger.debug("listening")
self.socket = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
self.socket.bind((self.hostname, self.port))
self.socket.listen(1)
while True:
conn, address = self.socket.accept()
self.logger.debug("Got connection")
process = multiprocessing.Process(target=handle, args=(conn, address))
process.daemon = True
process.start()
self.logger.debug("Started process %r", process)
if __name__ == "__main__":
logging.basicConfig(level=logging.DEBUG)
server = Server("0.0.0.0", 9000)
try:
logging.info("Listening")
server.start()
except:
logging.exception("Unexpected exception")
finally:
logging.info("Shutting down")
for process in multiprocessing.active_children():
logging.info("Shutting down process %r", process)
process.terminate()
process.join()
logging.info("All done")
但客户端,我认为错误是在我的循环中而真实
import socket, pickle
import numpy as np
import cv2
if __name__ == "__main__":
sock = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
sock.connect(("localhost", 9000))
data = "some data"
sock.sendall(data.encode())
data = []
while True:
packet = sock.recv(1024)
if not packet: break
data.append(packet)
print("toto")
data_arr = pickle.loads(b"".join(data))
print(data_arr)
sock.close()
