从foursquare发出请求

Question

我正在尝试使用下面的函数来检索不同位置的场所，但是我一直收到此错误，我无法弄清楚，因为我以前使用过它，并且可以在不同位置完美地工作。请帮助！

def getNearbyVenues(names, latitudes, longitudes, radius=500):

    venues_list=[]
    for name, lat, lng in zip(names, latitudes, longitudes):
        print(name)

        # create the API request URL
        url = 'https://api.foursquare.com/v2/venues/explore?&client_id={}&client_secret={}&v={}&ll={},{}&radius={}&limit={}'.format(
            CLIENT_ID, 
            CLIENT_SECRET, 
            VERSION, 
            lat, 
            lng, 
            radius, 
            LIMIT)

        # make the GET request
        results = requests.get(url).json()["response"]['groups'][0]['items']

        # return only relevant information for each nearby venue
        venues_list.append([(
            name, 
            lat, 
            lng, 
            v['venue']['name'], 
            v['venue']['location']['lat'], 
            v['venue']['location']['lng'],  
            v['venue']['categories'][0]['name']) for v in results])

    nearby_venues = pd.DataFrame([item for venue_list in venues_list for item in venue_list])
    nearby_venues.columns = ['Neighbourhood', 
                  'Neighbourhood Latitude', 
                  'Neighbourhood Longitude', 
                  'Venue', 
                  'Venue Latitude', 
                  'Venue Longitude', 
                  'Venue Category']

    return(nearby_venues)`

london_venues = getNearbyVenues(names=df['Location'],
                                   latitudes=df['Latitude'],
                                   longitudes=df['Longitude']
                                  )

这是我得到的错误

KeyError: 'groups'

如果您使用的是沙箱帐户，则可能已超出API调用限制，或者没有名为“ groups”的密钥。如果没有，请提供位置的坐标。
