Java REST api 使用 HTTP PUT 方法发送数组

Question

我无法在 Java

中实现 REST API

我有一个使用 PHP 的通用实现的工作示例。

如何使用 json 库和 HttpClient（HttpPut 请求）在 Java 中实现它？

这是PHP例子

//DATA TO UPDATE
$postData = array(
    'item'   => array(
        'title'              => 'My title',
        'personal_reference' => 'My personal ref',
        'qty'                => 3,
        'description'        => 'My description'
    )
);


//RESOURCE CALL WITH PUT METHOD
$url = 'https://rest.restserv.com/item/1234?token=MyPersonalToken';
$ch = curl_init();
curl_setopt ($ch, CURLOPT_URL, $url);
curl_setopt ($ch, CURLOPT_POSTFIELDS, http_build_query($postData) );
curl_setopt ($ch, CURLOPT_CUSTOMREQUEST, "PUT");
curl_setopt ($ch, CURLOPT_FOLLOWLOCATION, true);
curl_setopt ($ch, CURLOPT_RETURNTRANSFER, true);
$xml_response  = curl_exec($ch);

我的（无效）方法是这样的：

Map<String,String> dataMap = new HashMap<String,String>();
dataMap.put("title", "some text");
dataMap.put("personal_reference", "my ref");
dataMap.put("qty", "1");
dataMap.put("description", "some desciption text");

String url = "https://rest.restserv.com/item/1234?token=MyPersonalToken";

HttpPut putRequest = new HttpPut(url);

MultipartEntityBuilder builder = MultipartEntityBuilder.create();
for (Map.Entry<String, String> entry : dataMap.entrySet()) {
    builder.addTextBody(entry.getKey(), entry.getValue());
}
putRequest.setEntity(builder.build());
response = httpClient.execute(putRequest);

谢谢和最诚挚的问候。

更新

现在我正在尝试使用另一种方法。对象 Map dataMap 包含要发送的项目的所有详细信息。不幸的是，我仍然无法发送项目详细信息。请求状态为200，响应正常。

HttpClient httpClient = HttpClientBuilder.create().build();
HttpPut putRequest = new HttpPut(url);
putRequest.addHeader("Content-Type", "application/json; charset=utf-8");
JSONArray itemDetails = new JSONArray();                
itemDetails.put(dataMap);               
JSONObject root = new JSONObject().put("item", itemDetails);
StringEntity entity = new StringEntity(root.toString(2),  "UTF-8");
System.out.println("ROOT is:::: "+root.toString(2));
putRequest.setEntity(entity);
response = httpClient.execute(putRequest);

root.toString(2) 结果是：

{"item": [{"title": "My title","personal_reference": "My personal ref","qty": "3","description": "My description"}]}

问题

负载的格式似乎不正确，被 REST 服务器跳过了。

解决方案

问题已使用 kong.unirest.Unirest 库解决。
