使用协调器模式在控制器之间传递数据

class Coordinator:
    def __init__(self):
        self.data = {}

    def set_data(self, key, value):
        self.data[key] = value

    def get_data(self, key):
        return self.data.get(key)

class ControllerA:
    def __init__(self, coordinator):
        self.coordinator = coordinator

    def do_something(self):
        self.coordinator.set_data('key_a', 'value_a')

class ControllerB:
    def __init__(self, coordinator):
        self.coordinator = coordinator

    def do_something(self):
        value = self.coordinator.get_data('key_a')
        print(f"ControllerB received data: {value}")

# 使用示例
coordinator = Coordinator()
controller_a = ControllerA(coordinator)
controller_b = ControllerB(coordinator)

controller_a.do_something()
controller_b.do_something()
