如何从节点 express mongoose mongoDb 中的地理位置数据中获取城市名称

Question

I have this document in my collection inside a db in MongoDB

{
 name: "steve",
 id: 11,
 address: "24 rue Victor Hugo"
 geolocation:
 {latitude:"16.66667",longitude:"101.18333"}
}

I want to get the city name from the geolocation data, I am working in Vs with node, express and mongoose. I tried to find a way to do without manipulating my db, because I already have my collection set before starting.

Answer 1

You can make requests with your geolocation parameters for address information. https://maps.googleapis.com/maps/api/geocode/json?latlng=40.714224,-73.961452&key=YOUR_API_KEY

Answer 2

What you are trying to do is called reverse geocoding. It is available through the Google Maps Geocoding API. You have to sign up for a Google Developers account. Afterwards, you create a project from the Google Developers console. You can then request an API key. You can then use this API key in your request to the Google Maps API as follows:

https://maps.googleapis.com/maps/api/geocode/json?latlng=16.66667,101.18333&key=YOUR_API_KEY

Take a look at Google's Goecoding API documentation here . You can also test that URL in a browser to see the returned JSON-result, or using curl from the command-line.
