扭曲似乎無法調用數據

Question

我一直在編寫一個概念驗證型程序，該程序通過網絡發送屏幕截圖，由於某種原因，在發送數據后未調用dataRecieved方法。 這是我的代碼

服務器

from twisted.internet import protocol, reactor
from twisted.internet.endpoints import TCP4ServerEndpoint
from PIL import Image

class ImageProto(protocol.Protocol):
    def dataReceived(self, data):
        print("test")
        print(isinstance(Image.open(data), Image.Image))
class ImageProtoFactory(protocol.Factory):
    def buildProtocol(self, addr):
        return ImageProto()
endpoint = TCP4ServerEndpoint(reactor, 1336)
endpoint.listen(ImageProtoFactory())
reactor.run()

from twisted.internet.protocol import Protocol
from twisted.internet import reactor
from twisted.internet.endpoints import TCP4ClientEndpoint, connectProtocol
from PIL import ImageGrab
from io import BytesIO

class ImageSender(Protocol):
    def connectionMade(self):
        i = ImageGrab.grab()
        i.resize((1280, 720))
        output = BytesIO()
        i.save(output, format = "png")
        output.flush()
        self.transport.write(output.getvalue())
        self.transport.loseConnection()
        reactor.stop()
point = TCP4ClientEndpoint(reactor, "localhost", 1336)
d = connectProtocol(point, ImageSender())
reactor.run()

當在connectionMade的末尾調用reactor.stop時，您將立即關閉整個過程，然后再發送任何數據。 刪除它，就可以了。
