如何从返回中获取数据

Question

我的 function 向我返回数据，如下所示。 如何从这些数据中获取特定信息，例如country ？

[ { latitude: 52.6997543,
    longitude: 15.2602551,
    country: 'Poland',
    city: 'Gorzów Wielkopolski',
    state: 'Lubusz Voivodeship',
    zipcode: '66-446',
    streetName: 'Zieleniecka',
    streetNumber: '4',
    countryCode: 'pl',
    county: 'Gorzów Wielkopolski',
    extra: { confidence: 10, confidenceKM: 0.25 },
    provider: 'opencage' } ]

这是我的 function：

fn: async function({address, country, zipCode}){
        // const location = address + ' ' + city
        const response = await geocoder.geocode({
            address: address,
            country: country,
            zipcode: zipCode,
            minConfidence: 0.5,
            limit: 1
        })
        return response
    }

Answer 1

由于您的数据是包含在列表中的 object，因此您可以访问国家/地区属性，如下所示：

 var list = [ { latitude: 52.6997543, longitude: 15.2602551, country: 'Poland', city: 'Gorzów Wielkopolski', state: 'Lubusz Voivodeship', zipcode: '66-446', streetName: 'Zieleniecka', streetNumber: '4', countryCode: 'pl', county: 'Gorzów Wielkopolski', extra: { confidence: 10, confidenceKM: 0.25 }, provider: 'opencage' } ]; console.log(list[0].country);
