我在我的 Android 应用程序中使用带有服务的 drupal，当我使用用户名和密码连接到 REST 服务器时，我得到 200 的响应，这没问题，但是当我尝试创建节点时，它返回 401 错误。

我正在使用 HttpClient，我应该关心设置 cookie 还是有什么问题？登录并保持创建节点或用户的身份验证的正确方法是什么......等等。

有什么建议或想法吗？

    HttpResponse response = null;
HttpPost postRequest = null;
HttpClient httpClient = new DefaultHttpClient();
  try {


    postRequest = new HttpPost(
        "http://192.168.1.104/?q=rest/user/login");

    String  loginString=String.format("{\"username\":\"%s\",\"password\":\"%s\"}", "user","pass");
    Log.d("expression",loginString);
    StringEntity input = new StringEntity(nodeText  );

    input.setContentType("application/json");
    postRequest.setEntity(input);

response = httpClient.execute(postRequest);





    if (response.getStatusLine().getStatusCode() != 201) {

    }

    BufferedReader br = new BufferedReader(
                    new InputStreamReader((response.getEntity().getContent())));

    String output;
    System.out.println("Output from Server .... \n");
    while ((output = br.readLine()) != null) {

    }



  } catch (MalformedURLException e) {

    e.printStackTrace();

  } catch (IOException e) {

    e.printStackTrace();

  }


// here is the code to create a node  

  try {


    HttpPost postRequest2 = new HttpPost(
        "http://192.168.1.104/?q=rest/node");

    String nodeText= String.format( "{\"type\":\"story\",\"title\":\" %s \",\"body\":\" %s \"}", title,"");
   Log.d("expression",nodeText);
    StringEntity input = new StringEntity(nodeText  );


    input.setContentType("application/json");

    postRequest2.setEntity(input);

    response = httpClient.execute(postRequest2);


    if (response.getStatusLine().getStatusCode() != 201) {

    }
    System.out.println(response.getStatusLine().getStatusCode());

    BufferedReader br = new BufferedReader(
                    new InputStreamReader((response.getEntity().getContent())));

    String output;
    System.out.println("Output from Server .... \n");
    while ((output = br.readLine()) != null) {
        System.out.println(output);
    }

    httpClient.getConnectionManager().shutdown();

  } catch (MalformedURLException e) {

    e.printStackTrace();

  } catch (IOException e) {

    e.printStackTrace();

  }
}

编辑解决方案： 最后，问题出在drupal方面，您应该在设置服务器时检查会话身份验证，在我的情况下是休息:)所以，现在我相信，httpClient会自动管理cookies。

您似乎需要 cookie。

您通常会从登录方法中获取 cookie 作为响应。得到它，把它储存起来，然后把它拉出来，贴在HttpPostala 的标题中：

HttpPost post = new HttpPost(uri);
SharedPreferences settings = context.getSharedPreferences(LOGIN_PREFS, 0);
String cookie = settings.getString(kCOOKIE, "");
post.addHeader("Cookie", cookie);
