我的目标是通过 Python 从 stocktwits 下载推文。

我找到了 Jason Haury 的这个脚本 。可悲的是，我无法让它运行。到目前为止，我所做的是下载“api.py”和“requestors.py”脚本，并用我的访问令牌替换后者的“ST_ACCESS_TOKEN”。但是，当我运行命令get_watched_stocks(my_watchlist_id)时，我收到以下错误：

ipython-input-12-b889976b3838> in get_watched_stocks(wl_id)
    115     """ Get list of symbols being watched by specified StockTwits watchlist
    116     """
--> 117     wl = R.get_json(ST_BASE_URL + 'watchlists/show/{}.json'.format(wl_id), params=ST_BASE_PARAMS)
    118     wl = wl['watchlist']['symbols']
    119     return [s['symbol'] for s in wl]
TypeError: unbound method get_json() must be called with Requests instance as first argument (got str instance instead)

有人知道我可能做错了什么吗？如果没有：有人可以逐步解释我如何使用 Haury 先生或任何其他脚本从 stocktwits 下载推文吗？

您也可以使用 selenium，我的脚本适用于 CC_transcript，但您可以将其应用于任何 stocktwits 帐户：

@annach 看看pytwits，它是 StockTwits 的 REST-API 的 Python 包装器。

由于该项目非常年轻，它远非完美，但要在监视列表中获取符号列表，您只需执行以下操作：

pip install pytwits

接着：

import pytwits


def main():

    access_token = 'TOKEN'
    stocktwits = pytwits.StockTwits(access_token=access_token)

    watchlist = stocktwits.watchlists(path='show', id='WL_ID_HERE')
    print('\n\n'.join([symbol['symbol'] for symbol in watchlist.symbols]))


if __name__ == '__main__':
    main()

取自examples-folder中的监视列表示例。

如果您查看在 requestors.py 中创建的 Requests 类，看起来创建者希望它们成为该类的静态方法，但实际上忘记了将它们设为静态方法。如果您进入该文件并@staticmethod在两个函数定义上方放置一个，它将起作用。例如

def get_json(url, params=None):

现在变成

@staticmethod def get_json(url, params=None):

测试并确认
