elgg web服務客戶端

Question

我正在編寫一個自定義但簡單的客戶端來測試使用Java的elgg Web服務。 我想用一個簡單的參數向服務器發送一個post請求但是。

這是我在elgg中的暴露函數：

function hello_world($name) {
    return "Hello ".$name;
}


elgg_ws_expose_function(
    "test.echo",
    "hello_world",
    array("name" => array("type" => "string", "required" => true)),
    'A testing method which echos back a string',
    'POST',
    false,
    false
);

這是我發送帖子請求的java代碼：

public class Main {

    public static void main(String[] args) {


        try {
            CloseableHttpClient client = HttpClients.createDefault();
            JSONObject object = new JSONObject();
            String name = "Mousa";
            object.put("name", name);
            HttpPost httpPost = new      HttpPost("http://localhost/elgg/services/api/rest/json?method=test.echo");
        httpPost.setHeader("Accept", "application/json");
        httpPost.setHeader("Content-type", "application/json");
        StringEntity entity = new StringEntity(object.toJSONString());
        System.out.println(object);
        httpPost.setEntity(entity);
        CloseableHttpResponse response = client.execute(httpPost);
        System.out.println(response.getStatusLine().getStatusCode());
        HttpEntity httpEntity = response.getEntity();
        StringBuilder stringBuilder = new StringBuilder();
            InputStream inputStream = httpEntity.getContent();
            BufferedReader bufferedReader = new BufferedReader(new InputStreamReader(inputStream));
            String line;
            while((line = bufferedReader.readLine()) != null) {
                stringBuilder.append(line);
            }
            inputStream.close();
            System.out.println(stringBuilder.toString());
        client.close();
        }
        catch(Exception ex) {
            System.out.println(ex.getLocalizedMessage());
        }
    }
}

但是我收到了這個輸出，並且發布請求有問題。 我不知道該代碼有什么問題：

{"name":"Mousa"}

200


{"status":-1,"message":"Missing parameter name in method test.echo"}

它說“名稱”參數丟失！

請幫忙

據我記憶，Elgg的Web服務無法在請求體中處理JSON，而是使用序列化查詢字符串，例如：

name=Mousa&interest[]=interest1&interest[]=interest2

Elgg可能會使用parse_str() ，所以這可能會有所幫助： http ： parse_str()
