使用Spring RestTemplate时,REST POST可以正常使用POSTMAN,但是异常

Question

我正在编写一个Rest客户端来使用Spring RestTemplate发布JSON数据.在正文中使用POSTMAN和跟随JSON数据获得正确的响应 -

{
    "InCode":"test",
    "Name":"This is  test",
    "Email":"test@gmail.com",
    "Id":18,
}

但是,当尝试使用Spring RestTemplate按如下方式命中REST API时

ResponseEntity<String> response = restTemplate.exchange(baseUrl,
                HttpMethod.POST, getHeaders(), String.class);

private HttpEntity<?> getHeaders() throws JSONException {
JSONObject request = new JSONObject();
        request.put("Email", "test@gmail.com");
        request.put("Id", "18");
        request.put("Name", "This is  test");
        request.put("InCode", "test");

        headers.set("Accept", MediaType.APPLICATION_JSON_VALUE);
        return new HttpEntity<>(request.toString(), headers);
        }

我得到例外 -

11:52:56.808 [main] DEBUG o.s.web.client.RestTemplate - Created POST request for "http://server-test/platform/v4/org"
11:52:56.815 [main] DEBUG o.s.web.client.RestTemplate - Setting request Accept header to [text/plain, application/json, application/*+json, */*]

感谢任何帮助.

您正在设置“接受”标头，它定义您将接受哪种内容类型作为响应。

相反，您必须使用“application/json”设置标题“Content-Type”。

编辑：

在您的 java 代码中 id 是一个字符串，在邮递员中它是一个数字。可能这会使服务器失败？
