python 后无法从 Quandl 获取数据

Question

我试过下面的代码（写在文件test.py中）：

import pandas as pd
import quandl
d=quandl.get('WIKI/PRICES')

我收到了这条错误信息：

Traceback (most recent call last):
  File "C:\Python36\lib\site-packages\quandl\connection.py", line 55, in parse
    return response.json()
  File "C:\Python36\lib\site-packages\requests\models.py", line 892, in json
    return complexjson.loads(self.text, **kwargs)
  File "C:\Python36\lib\json\__init__.py", line 354, in loads
    return _default_decoder.decode(s)
  File "C:\Python36\lib\json\decoder.py", line 339, in decode
    obj, end = self.raw_decode(s, idx=_w(s, 0).end())
  File "C:\Python36\lib\json\decoder.py", line 357, in raw_decode
    raise JSONDecodeError("Expecting value", s, err.value) from None
json.decoder.JSONDecodeError: Expecting value: line 1 column 1 (char 0)

During handling of the above exception, another exception occurred:

Traceback (most recent call last):
  File "C:/Users/L.Shane/Desktop/test.py", line 3, in <module>
    d=quandl.get('WIKI/PRICES')

    data = Dataset(dataset_args['code']).data(params=kwargs, handle_column_not_found=True)

    return Data.all(**updated_options)

    return cls.execute_request(http_verb, abs_url, **options)
  File "C:\Python36\lib\site-packages\quandl\connection.py", line 44, in execute_request
    cls.handle_api_error(response)

    error_body = cls.parse(resp)
  File "C:\Python36\lib\site-packages\quandl\connection.py", line 57, in parse
    raise QuandlError(http_status=response.status_code, http_body=response.text)
quandl.errors.quandl_error.QuandlError: (Status 403) Something went wrong. Please try again. If you continue to have problems, please contact us at connect@quandl.com.

我该如何前进？

更新：我也在R中试过：

 mydata = Quandl("WIKI/PRICES")

现在我得到这个错误：

Cloudflare 验证码似乎被阻止了（我不确定）。

Answer 1

我认为您需要将您的身份验证令牌传递给它：

quandl.get("EOD/AAPL", authtoken="...")

这是 Apple (AAPL) 的returns收盘价。

Answer 2

如果您在输入 quandl.get("...") 时未获取数据并且显示错误。然后你需要去quandl。在搜索选项中输入 "GOOGLE STOCK"。然后单击您选择的数据集 select。之后转到库并单击 python 并获得类似 quandl.get("....dataset",authtoken="....") 的内容。复制并粘贴到您的命令 shell.
