Python 2.7 python天气API位置id

对于上面的命令，我得到10个结果。我想要一个特定的位置，比如印度的普纳。如何获取它？

我查看了pywapi的源代码，发现搜索字符串将在

get\u loc\u id\u from\u waather\u com

中被引用（url encode，例如，“，”将被引用到“%2C”）

因此，当您调用

pywapi.get\u loc\u id\u from\u weather\u com（“Pune，MH，India”）

时，它将请求url:

http://xml.weather.com/search/search?where=Pune%2CMH%2CIndia

但不是

http://wxdata.weather.com/wxdata/search/search?where=Pune，MH，印度

。而前者肯定没有结果

一个解决方案是您可以修改（破解）pywapi。只需编辑pywapi.py并找到

get\u loc\u id\u from\u weather\u com

函数。将行

url=LOCID\u SEARCH\u url%quote（SEARCH\u string）

替换为

url=LOCID\u SEARCH\u url%quote（SEARCH\u string，，）

，现在您可以：

a=pywapi.get_loc_id_from_weather_com("pune")


{0: (u'TTXX0257', u'Pune, OE, Timor-leste'), 
 1: (u'INXX0102', u'Pune, MH, India'), 
 2: (u'BRPA0444', u'Pune, PA, Brazil'),
 3: (u'FRBR2203', u'Punel, 29, France'), 
 4: (u'IDVV9705', u'Punen, JT, Indonesia'),
 5: (u'IRGA2787', u'Punel, 19, Iran'),
 6: (u'IRGA2788', u'Punes, 19, Iran'),
 7: (u'IDYY7030', u'Punen, JI, Indonesia'), 
 8: (u'RSUD1221', u'Punem, UD, Russia'),
 9: (u'BUXX2256', u'Punevo, 09, Bulgaria'),    
'count': 10}

附言： pywapi的源代码：

In [2]: import pywapi

In [3]: pywapi.get_loc_id_from_weather_com("Pune,MH,India") # no spaces
Out[3]: {0: (u'INXX0102', u'Pune, MH, India'), 'count': 1}

def get_loc_id_from_weather_com(search_string):
    """Get location IDs for place names matching a specified string.
    Same as get_location_ids() but different return format.

    Parameters:
      search_string: Plaintext string to match to available place names.
      For example, a search for 'Los Angeles' will return matches for the
      city of that name in California, Chile, Cuba, Nicaragua, etc as well
      as 'East Los Angeles, CA', 'Lake Los Angeles, CA', etc.

    Returns:
      loc_id_data: A dictionary of tuples in the following format:
      {'count': 2, 0: (LOCID1, Placename1), 1: (LOCID2, Placename2)}
