问题陈述

我的审判

1. 我手动尝试通过Chrome&我正在接收数据。意思是
2. 我试图调用localhost(而不是overpassapi),它通过OkHttp3响应。意思是 好的第3页

URL="http://overpass-api.de/api/interpreter";
value ="?data=way(around:100,22.36432,73.19266)[power~\"\"];(._;>;);out;";
HttpCaller API =new HttpCaller();
response.getWriter().println(API.APIGet(URL+value));

类调用立交桥API

import java.io.IOException;
import java.util.concurrent.TimeUnit;
import okhttp3.OkHttpClient;
import okhttp3.Request;
import okhttp3.Response;

public class HttpCaller
{
    OkHttpClient client;
    String rspns;

    public HttpCaller()
    {
        try
        {
            client = new OkHttpClient();
            OkHttpClient.Builder builder = new OkHttpClient.Builder();
            builder.connectTimeout(30, TimeUnit.SECONDS); 
            builder.readTimeout(30, TimeUnit.SECONDS); 
            builder.writeTimeout(30, TimeUnit.SECONDS); 
            client = builder.build();
        }
        catch (Exception e) {e.printStackTrace();System.out.println(e);}
    }

    public String APIGet(String url) throws IOException
    {       
        Request request = new Request.Builder()
            .url(url)
            .build();
        System.out.println(request.url());

        try 
        { 
            Response response = null;
            System.out.println("new Call...");
            response = client.newCall(request).execute();
            System.out.println(response.code());
            rspns =  response.body().string(); 
        } catch (Exception e) {e.printStackTrace();System.out.println("Exception is "+e);} 

        return rspns;
    }
}
