使用简单虹吸ACIS请求引发的异常

Question

我在Google和虹吸0.9中使用了以下代码：

from siphon.simplewebservice import acis
import json
params = {"sid":"KPIH","elems":"maxt,mint,avgt,pcpn,snow,snwd"}
ds = acis.acis_request("StnData", params)

由此产生的错误：

JSONDecodeError: Expecting value: line 1 column 1 (char 0)

During handling of the above exception, another exception occurred:

AcisApiException                          Traceback (most recent call last)
/usr/local/lib/python3.7/dist-packages/siphon/simplewebservice/acis.py in acis_request(method, params)
     60         raise AcisApiException('Bad URL. Check your ACIS connection method string.')
     61     except ValueError:
---> 62         raise AcisApiException('No data returned! The ACIS parameter dictionary'
     63                                'may be incorrectly formatted')
     64 

AcisApiException: No data returned! The ACIS parameter dictionarymay be incorrectly formatted

使用木星实验室也导致了同样的错误。

Answer 1

通过将开始日期和结束日期添加到查询中，修正了该问题。

params = {"sid":"KPIH","elems":"maxt,mint,avgt,pcpn,snow,snwd","sdate":"por","edate":"por"}
