Python实现股票行情接收V010

本次版本增加如下功能：

1、增加一个新的行情源：QQ行情源：http://qt.gtimg.cn

2、修改主循环，新增一个线程来获取行情

3、增加股票跟踪功能，当跟踪股票最新价格高于止盈比例或是止损比例的时候，播放声音提醒

1、增加一个新的行情源， 例如：http://qt.gtimg.cn/r=0.9392363841179758&q=sh600006，获取的数据与sina的行情有区别，如下：

v_sh600006="1~东风汽车~600006~3.04~3.07~3.07~53132~20602~32530~3.04~127~3.03~2306~3.02~1304~3.01~2929~3.00~4115~3.05~1817~3.06~822~3.07~3135~3.08~2828~3.09~2197~14:59:54/3.04/40/B/12160/16286|14:59:49/3.03/1/S/336/16280|14:59:34/3.04/46/B/13984/16264|14:59:29/3.04/10/B/3040/16252|14:59:09/3.03/64/S/19396/16231|14:59:04/3.05/49/B/14934/16224~20140403150300~-0.03~-0.98~3.08~3.01~3.04/53132/16195550~53132~1620~0.27~121.16~~3.08~3.01~2.28~60.80~60.80~1.02~3.38~2.76~";

该方法是通过腾讯行情网站抓http报文找到的，其中r=0.9392363841179758不知道什么意思，改成其他值也可以查询，请知道的朋友告诉一声。另外该数据中部分数据还没有解析完事什么意义，因此只是简单的解析了几个主要的字段，不多说了，获取行情数据代码如下：

class QuoteSourceQtimg(QuoteSource):    def queryStock(self):            host="http://qt.gtimg.cn/r=0.9392363841179758&q="        url = host + self.stocks        req = urllib2.Request(url)        res_data = urllib2.urlopen(req)        res = res_data.read()        d = QuoteData()        for line in res.split(';'):            #print line            if len(line) < 50 :                continue            info = line[12: 100]            #print info            vargs = info.split('~')            #print vargs            d.stockName = vargs[1]            d.stockid = vargs[2]            d.lastPrice = vargs[3]            d.preClose = vargs[4]            d.openPrice = vargs[5]            d.lowPrice = ''            d.highPrice = ''            d.avgPrice = ''            self.notifyListeners(d);

2、修改主循环，新增一个线程来获取行情，这个不用多说，只是新建一个线程子类，然后再run中写循环查询即可：

class QuoteThread(threading.Thread):    def __init__(self, source, intervalSecs = 3):        self.source = source        self.interval = intervalSecs        self.threadRunning = False        threading.Thread.__init__(self)    def run(self):        print 'StockQuote run'        self.threadRunning = True;        while self.threadRunning:            self.source.queryStock()            sleep(self.interval)    def stop(self):        print 'StockQuote stop'        self.threadRunning = False;

3、增加股票跟踪功能，当跟踪股票最新价格高于止盈比例或是止损比例的时候，播放声音提醒

实现一个类QuoteInformer直接从QuoteListener派生，这样不用改获取行情部分的代码了，然后判断是否超出止损和止盈值：

class QuoteInformer(QuoteListener):    def __init__(self, stock, cmpPrice = 0.0, lowper = -2, highper = 2):        QuoteListener.__init__(self, 'Inform')        self.stockid = stock        self.lowper = lowper        self.highper = highper        self.cmpPrice = cmpPrice        self.preClose = 0.0        self.lastPrice = 0.0        self.playThread = 0            def OnQuoteRecv(self, quoteData):        if cmp(self.stockid, quoteData.stockid) == 0 :            #self.printInfo(0.0)            if self.cmpPrice == 0.0 :                self.cmpPrice = string.atof(quoteData.lastPrice)                self.preClose = string.atof(quoteData.preClose)            self.lastPrice = string.atof(quoteData.lastPrice)            curper = (self.lastPrice - self.cmpPrice) / self.cmpPrice * 100            self.printInfo(curper)            if curper <= self.lowper :                self.playLowSound()            elif curper >= self.highper :                self.playHighSound()    def playLowSound(self):        self.playThread = PlayThread(3)        self.playThread.playSound("F:\KuGou\wav\level_up.wav")    def playHighSound(self):        self.playThread = PlayThread(3)        self.playThread.playSound("F:\KuGou\wav\msg.wav")    def printInfo(self, curper) :        print "stockid  curper  lastPrice  cmpPrice  lowper   highper  preClose"        print "%s  %f  %f  %f %f %f %f" % (self.stockid, curper, self.lastPrice, self.cmpPrice, self.lowper, self.highper, self.preClose)

播放声音，这里直接使用winsound来播放声音，不过遗憾的是这个只能播放wav格式的音频文件，暂时也就这样吧，以后有需要再增加代码播放其他音频文件。

class PlayThread(threading.Thread):

    def __init__(self, count):        self.wavfile = ""        self.loopcount = count        threading.Thread.__init__(self)    def playSound(self, wavfile):        self.wavfile = wavfile        self.start()    def run(self):        count = self.loopcount        while count > 0 :            count = count - 1            self.playSoundOnce()    def playSoundOnce(self):        winsound.PlaySound(self.wavfile,winsound.SND_FILENAME)

需要代码的同学可以直接向我要，要不我还是建一个git库，将代码共享上去大家都可以直接下载，不过暂时先这样吧，改天再上传上去了。

最后，还是那句话，请了解股票的朋友们多多提建议，看能否实现更多功能帮助大家分析股票。
