java - Elgg Web服务客户端

我正在编写一个自定义但简单的客户端，以使用Java测试Elgg Web服务。我想使用一个简单的参数向服务器发送发布请求。

这是我在elgg中公开的函数：

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
);

这是我的Java代码，用于发送发布请求：

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());
        }
    }
}

但是我收到此输出，并且后期请求有问题。我不知道该代码出了什么问题：

{"name":"Mousa"}

200


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

它说“名称”参数丢失！！！

请帮忙

最佳答案

据我所知，Elgg的Web服务无法在请求正文中处理JSON，而是使用序列化查询字符串，例如：

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

Elgg可能会使用parse_str()，因此这可能会有所帮助：http://php.net/manual/en/function.parse-str.php
