追踪数字足迹：通过API和离线库查询IP地址的解决方案（详解带源码）

public static void main(String[] args) throws IOException, InterruptedException {
        String urlArr = "https://api.ipdatacloud.com/v2/query?ip=&key=";
        HttpClient httpClient = HttpClient.newBuilder().build();

        HttpRequest getRequest = HttpRequest.newBuilder()
                .GET()
                .uri(URI.create(urlArr))
                .build();

        // 发送GET请求并获取响应
        HttpResponse<String> resp = httpClient.send(getRequest, HttpResponse.BodyHandlers.ofString());

        //对返回的json数据做解析
        ObjectMapper objectMapper = new ObjectMapper();
        JsonNode rootNode = objectMapper.readTree(resp.body());
        String data = rootNode.get("data").get("location").asText();
        Location location = objectMapper.readValue(data, Location.class);
        System.out.println(location.toString());

    }
