cmd_test.py执行时astock.py中getStockDailyPrice()多线程调用时出错

[ngg1285]

cmd_test.py执行时x=market.get_price("000044.SZ",'20180102')获取不到值，但是df=AStock.getStockDailyPriceByCode('000043.SZ',fq='no')可以获取到值。
运行过程中，会发生错误，在astock.py
在以下行出现多线程的错误
mytask=pool.submit(AStock.getStockDailyPriceByCode,code=code,where=where,startdate=startdate,enddate=enddate,fq=fq)

Exception has occurred: RuntimeError (note: full exception trace is shown but execution is paused at: )

    An attempt has been made to start a new process before the
    current process has finished its bootstrapping phase.

    This probably means that you are not using fork to start your
    child processes and you have forgotten to use the proper idiom
    in the main module:

        if __name__ == '__main__':
            freeze_support()
            ...

    The "freeze_support()" line can be omitted if the program
    is not going to be frozen to produce an executable.

代码是在linux平台上开发的，windows平台还没经过严格测试，后面等有时间了修复下
