Question

我尝试了以下代码（用test.py文件编写）：

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

我收到此错误消息：

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:

    d=quandl.get('WIKI/PRICES')

    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.

我怎样才能前进？

更新：我也在R中尝试过它：

 mydata = Quandl("WIKI/PRICES")

现在我收到了这个错误：

似乎Cloudflare Captcha正在阻止（我不确定）。

Answer 1

我相信你需要传递你的身份验证令牌：

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

这将返回Apple（AAPL）的结束日价格。

Answer 2

如果您没有获取数据，并且在键入quandl.get（“ ...”）时显示错误。然后，您需要转到quandl。在搜索选项中，输入“ GOOGLE STOCK”。然后单击您选择选择的数据集。之后，转到库并单击python，得到类似quandl.get（“ ..... dataset”，authtoken =“ ....”）的内容。复制此代码并将其粘贴到命令外壳中。

无法从python中的Quandl获取数据
