【java】get、post请求的远程调用

public String sendPostRequest() {
    //请求路径
    String inputHost = "http://172.0.0.1:8080/user/getUser";
    //请求报文
    String inputMessage = "{\"name\":\"张三\",\"age\":\"22\"}";
    RestTemplate client = new RestTemplate();
    //新建Http头，add方法可以添加参数
    HttpHeaders headers = new HttpHeaders();
    //设置请求发送方式
    HttpMethod method = HttpMethod.POST;
    //以表单的方式提交
    headers.setContentType(MediaType.APPLICATION_JSON);
    List<MediaType> list = new ArrayList<>();
    list.add(MediaType.APPLICATION_JSON_UTF8);
    headers.setAccept(list);
    //token修改下
    headers.set("Authorization", "token");
    //将请求头部和参数合成一个请求
    HttpEntity<String> requestEntity = new HttpEntity<>(inputMessage, headers);
    //执行HTTP请求，将返回的结构使用String 类格式化（可设置为对应返回值格式的类）
    ResponseEntity<String> response = client.exchange(inputHost, method, requestEntity, String.class);
    //返回报文
    String outputMessage = response.getBody();
    return outputMessage;
}

public String sendGetRequest(String url, Object message) {
    //请求路径
    String inputHost = "http://172.0.0.1:8080/user/getUser";
    //请求报文
    String inputMessage = "{\"name\":\"张三\",\"age\":\"22\"}";
    RestTemplate client = new RestTemplate();
