需要来自java的rest调用吗

我正在以客户端的身份调用API。我想用java来做这件事。我现在只需要回复。稍后我将转换输出。 我的代码如下：

String data = "User=admin&Password=1234&Authorization=basic&Keyword=nana";
URL url;
try {
    url = new URL("http://119.235.102.65/library/index.php/API/Search/basic");
HttpURLConnection conn = (HttpURLConnection) url.openConnection();
        conn.setDoOutput(true);
        conn.setRequestMethod("POST");

        OutputStreamWriter wr = new OutputStreamWriter(conn.getOutputStream());
        wr.write(data);
        wr.flush();

    int responseCode = conn.getResponseCode();
        System.out.println("Response code: " + responseCode);

        boolean isSuccesResponse = responseCode < 400;

        InputStream responseStream = isSuccesResponse ? conn.getInputStream() : conn.getErrorStream();

        wr.close();
         } catch (MalformedURLException e1) {
                // TODO Auto-generated catch block
                e1.printStackTrace();
            } catch (IOException e1) {
            // TODO Auto-generated catch block
            e1.printStackTrace();
        }

我还要从数据库中搜索一个关键字，那就是娜娜。

keyword=nana。

事实上，我使用POSTMAN rest client for Google Chrome尝试了您的rest api，您出现了错误：

不要使用

关键字=nana

用法：

keyword=nana

答案是：

是的。它需要授权。在代码示例中，您没有将凭据作为请求的一部分发送。这些可能需要作为头或请求参数发送。
