Learning to use the API

Learn to use the Get weather information API and get geocoding API to make a simple weather information collector (Gold API)

First, create a class openweathermapproxy to get information about the return.

Since I chose to return the data type as JSON, I first took the returned JSON with json2csharp.com to automatically generate the properties of the relevant information. And then two methods

Getadcode and GetWeather come back to return messages Adcode and Weatherinfo.

 Public classOpenweatherproxy { Public Static AsyncTask<rootobject> Getadcode (strings) {varHTTP =NewHttpClient (); varResponse =awaithttp. Getasync ("http://restapi.amap.com/v3/geocode/geo?address="+s+"&key= 's own development Id&output=json"); varresult =awaitResponse.            Content.readasstringasync (); varSerializer =NewDataContractJsonSerializer (typeof(Rootobject)); varms =NewMemoryStream (Encoding.UTF8.GetBytes (result)); vardata =(rootobject) serializer.            ReadObject (MS); returndata; }         Public Static AsyncTask<rootobject> GetWeather (strings) {varHTTP =NewHttpClient (); varResponse =awaithttp.
