我一直在尝试在 kivy GUI 模块（我的服务器）和另一个 python 模块（我的客户端）之间执行通信。但到目前为止，我在运行 xml rpc 服务器和 GUI run() 函数时遇到了问题。即使在线程中运行我的服务器后，我仍然遇到这个问题。我希望有人对如何修复我的代码，或者只是如何将 xml-rpc 与 kivy 一起提出建议。
这是我的代码：
import kivy
kivy.require('1.7.1')
from kivy.lang import Builder
from kivy.uix.gridlayout import GridLayout
from kivy.app import App
from threading import Thread
from kivy.clock import Clock
Builder.load_file('kivy_gui.kv')
class RoamClientInterface(GridLayout):
"""
Sets up connection with XMLRPC server
"""
move = False
"""
driveForward() -> Moves robot forward
"""
def driveForward(self):
self.move = True
"""
stop() -> stops robot from moving
"""
def stop(self):
self.move = False
def returnBool(self):
return self.move
class ClientInterface(App):
def build(self):
return RoamClientInterface()
def sendCommands(dt):
print "start"
print ""
from SimpleXMLRPCServer import SimpleXMLRPCServer
server = SimpleXMLRPCServer(("localhost", 5000))
print "initialize server"
print ""
server.register_instance(RoamClientInterface())
print "register instance"
print ""
# while True:
try:
print "try handle request"
print ""
server.handle_request()
print "print handle request"
print ""
except KeyboardInterrupt:
import sys
sys.exit()
if __name__ == '__main__':
serverThread = Thread(target=sendCommands(4))
serverThread.start()
# Clock.schedule_once(sendCommands)
ClientInterface().run()
