对象没有属性“结果”；多边形.io API

Question

我正在从 Polygon.io 中拉下一堆代码：

   from polygon import RESTClient
    key = 'KEY'
    all_tickers = []
    with RESTClient(key) as client:
        next_url = None
        while True:
            if next_url is None:
                tickers = client.reference_tickers_v3(type="CS")
            else:
                tickers = client._handle_response("ReferenceTickersV3ApiResponse", next_url, {})
            all_tickers.extend(tickers.results)
            if hasattr(tickers, 'next_url'):
                next_url = tickers.next_url
            else:
                break
                
    print(all_tickers)

然后我尝试循环遍历代码并提取每个代码的每日数据：

 with RESTClient(key) as client:
        from_ = "2022-01-01"
        to = "2022-02-01"
        
        for i in all_tickers:
            ticker =  i['ticker']
            resp = client.stocks_equities_aggregates(ticker, 1, "day", from_, to, unadjusted=False)

            print(f"Minute aggregates for {resp.ticker} between {from_} and {to}.")

            for result in resp.results:
                if result is None:
                    print('nothing')
                else:
                    print(result, 'result')

我的问题是我收到以下错误：

AttributeError: 'StocksEquitiesAggregatesApiResponse' object has no attribute 'results'

这是我的输出：

Minute aggregates for A between 2022-01-01 and 2022-02-01.

Minute aggregates for AAMC between 2022-01-01 and 2022-02-01.

我认为这是因为它到达了一个股票代码，然后没有结果属性。处理这个异常的正确方法是什么？

API 文档：https://polygon.io/docs/stocks/get_v2_aggs_ticker__stocksticker__range__multiplier___timespan___from___to

Answer 1

我使用 if 语句（来自 JS 背景），但不得不使用 try- except 代替：

  with RESTClient(key) as client:
        from_ = "2022-01-01"
        to = "2022-02-01"
        
        for i in all_tickers:
            ticker =  i['ticker']
            resp = client.stocks_equities_aggregates(ticker, 1, "day", from_, to, unadjusted=False)

            print(f"Minute aggregates for {resp.ticker} between {from_} and {to}.")

                    
            try:
                for result in resp.results:
                    print(result, 'result')
            except:
                print('nothing')
