从 GeocoderResponse 中提取坐标

Question

我正在尝试使用 Herepy 中的 Free_form 方法获取位置坐标。这个函数 returns 一个 Json 形式的数据列表（据我所知）。我想从此列表中提取某些数据。我尝试使用 json.loads() 但它 returns 出现以下错误：

TypeError: the JSON object must be str, bytes or bytearray, not 'GeocoderResponse'

数据如下所示：

{"Response": {"MetaInfo": {"Timestamp": "2019-06-02T16:46:46.588+0000"}, "View": [{"Result": [{"Location": {"Address":{"AdditionalData": [{"key": "CountryName", "value": "Nederland"}, {"key": "StateName", "value": "Noord-Holland"}, {"key": "CountyName", "value": "Haarlemmermeer"}], "City": "Nieuw-Vennep", "Country": "NLD", "County": "Haarlemmermeer", "Label": "Nieuw-Vennep, Noord-Holland, Nederland", "PostalCode": "2151 AR", "State": "Noord-Holland"}, "DisplayPosition":{"Latitude": 52.26388, "Longitude": 4.62986}, "LocationId": "NT_.gc2w3DtLRjNeEZj3hDvIB", "LocationType": "point", "MapView": {"BottomRight": {"Latitude": 52.25047, "Longitude": 4.65622}, "TopLeft": {"Latitude": 52.28503, "Longitude": 4.59986}}, "NavigationPosition": [{"Latitude": 52.26388, "Longitude": 4.62986}]}, "MatchLevel": "city", "MatchQuality": {"City": 0.5}, "Relevance": 1.0}], "ViewId": 0, "_type": "SearchResultsViewType"}]}}

或...

Answer 1

查看 the documentation，一个 GeocoderResponse 对象应该有一个 as_dict 方法，它应该给你想要的东西。它还应该有一个 as_json_string 方法，你可以使用 json.loads - stuff=json.loads(gr_obj.as_json_string).
