使用http3访问服务

用到的包：
import okhttp3.OkHttpClient;
import okhttp3.Request;
import okhttp3.Response;

主要代码：

try {
            //创建OkHttpClient对象
            OkHttpClient client = new OkHttpClient();
            //创建Request 对象
            Request request = new Request.Builder()
                    .url("HttpUr了")//请求接口。如果需要传参拼接到接口后面。
                    .build();
            Response response = null;
            //得到Response 对象
            response = client.newCall(request).execute();
            if (response.isSuccessful()) {
                String result = response.body().string();
                if(!"".equals(result)){
                    Map<String, Object> map = (Map<String, Object>)JSON.parse(result);
                    Map<String, Object> dataMap = (Map<String, Object>)map.get("data");
                    String id = StringUtils.nvlString(dataMap.get("ID"));
                    resultMap.put("statusCode",1000);
                    resultMap.put("id",id);
                }
            }else{
                resultMap.put("statusCode",2001);
                resultMap.put("message","XXXXX");
            }
            return CommonResult.buildSuccess(version, resultMap);
        } catch (Exception e) {
            e.printStackTrace();
            return CommonResult.error(Status.ERROR_5001);
        }
