我有这个Java代码:
import org.json.JSONArray;
import org.json.JSONObject;
public class PincodeToState {
private String myState;
public void setPincode(String pin) {
try {
JSONObject jsonObj = JsonParser
.getJSONfromURL("http://api.zippopotam.us/in/" + pin);
JSONArray Results = jsonObj.getJSONArray("places");
for (int i = 0; i < Results.length(); i++) {
JSONObject c = Results.getJSONObject(i);
myState = c.getString("state");
}
} catch (Exception e) {
e.printStackTrace();
}
}
public String getState() {
return myState;
}
}
Json代码
