元大期货API连接程序调试问题及修复方案

问题背景 #

团队调试元大期货API连接代码数周，已进入收尾阶段。在Anaconda Spyder中运行程序时，会弹出GUI登录窗口，但几秒后无响应，需强制关闭；输入账号密码后还会触发AttributeError: SetMktLogon错误，初步怀疑是缺失函数/包或未继承相关对象导致。

class MyApp(wx.App):
    def __init__(self, redirect=False, filename=None, useBestVisual=False, clearSigInt=True):
        super().__init__(redirect, filename, useBestVisual, clearSigInt)
        self.keepGoing = True
    def MainLoop(self, run_func):

        # Create an event loop and make it active.  If you are
        # only going to temporarily have a nested event loop then
        # you should get a reference to the old one and set it as
        # the active event loop when you are done with this one...
        evtloop = wx.GUIEventLoop()
        old = wx.EventLoop.GetActive()
        wx.EventLoop.SetActive(evtloop)

        # This outer loop determines when to exit the application,
        # for this example we let the main frame reset this flag
        # when it closes.
        while self.keepGoing:
            # At this point in the outer loop you could do
            # whatever you implemented your own MainLoop for.  It
            # should be quick and non-blocking, otherwise your GUI
            # will freeze.

            # call_your_code_here()
            run_func ()
            while not q.empty():
                next_job = q.get()
                DoJob (Bot, next_job)

            # This inner loop will process any GUI events
            # until there are no more waiting.
            while evtloop.Pending():
                evtloop.Dispatch()

            # Send idle events to idle handlers.  You may want to
            # throttle this back a bit somehow so there is not too
            # much CPU time spent in the idle handlers.  For this
            # example, I'll just snooze a little...
            time.sleep(0.10)
            evtloop.ProcessIdle()

        wx.EventLoop.SetActive(old)

def Oninit(self):
    self.keepGoing = True
    return True


def run_job():
    while not q.empty():
        next_job = q.get()
        DoJob(Bot, next_job)

if __name__ == "__main__":
    app=MyApp()    
    frame = AppFrame(None, title='YuantaQuoteAPI Sample',size = (670,370))
    frame.Show(True)
    Bot = StockBot(frame.Handle)    
    app.MainLoop(run_job)

解决方法 #

通过创建32位Python环境，并安装适配的32位wxPython后，问题完全解决，GUI可正常响应并完成登录操作。
