Question

我在机智的尽头试图破译为什么这不起作用。我正在尝试从Drupal 7实例中设置REST服务器。目前专注于不需要身份验证（一旦我设法让它说话，我会设置它。）

这是相关的代码位：

mymodule.module

/**
 * Implements hook_ctools_plugin_api().
 * Declares the mymodule services endpoint (stored in
 * mymodule.services.inc).  Note that the referenced ctools
 * hook obviates creating this endpoint through the UI.
 */
function mymodule_ctools_plugin_api($owner, $api) {
  if ($owner == 'services' && $api == 'services') {
    return array(
      'version' => 3,
      'file' => 'mymodule.services.inc',
      'path' => drupal_get_path('module', 'mymodule'),
    );
  }
}
/**
 * Implements hook_services_resources
 * Defines the resources available via services module (REST, in this case).
 *
 * @return array The definition array
 */
function mymodule_services_resources() {
  watchdog('mymodule', __FUNCTION__, array(), WATCHDOG_NOTICE, 'link');
    return array(
      '#api_version' => 3001,
      'test' => array(
        'retrieve' => array(
          'help' => t("A test of the REST api"),
          'file' => array(
            'type' => 'inc',
            'module' => 'mymodule',
            'name' => 'resources/test_resource',
          ),
          'access arguments'=>array('access content'),
          'callback' => 'mymodule_services_test',
          'args' => array(
            array(
              'name' => 'id',
              'type' => 'int',
              'description' => t("a test of rest arguments"),
              'source' => array('path' => '0'),
              'optional' => FALSE,
            ),
          ),
        ),
        'index' => array(
          'help' => t('A test of the REST api index functionality'),
          'file' => array(
            'type' => 'inc',
            'module' => 'mymodule',
            'name' => 'resources/test_resource',
          ),
          'callback' => 'mymodule_services_test',
        ),

      ),
    );
}

资源/ test_resources.inc

/**
 *
 */
function mymodule_services_test() {
  watchdog('mymodule', __FUNCTION__, array(), WATCHDOG_NOTICE, 'link');
  $result = array('foo' => 'bar');
  drupal_json_output($result);
}
/**
 * Access callback for test services (currently unused)
 * @param  string $op   The operation being performed: creat
 * @param  [type] $args [description]
 * @return [type]       [description]
 */
function mymodule_services_test_access($op, $args) {
  watchdog('mymodule', __FUNCTION__, array(), WATCHDOG_NOTICE, 'link');
  return TRUE;
}

mymodule.services.inc

/**
 * @file
 */

/**
 * Implements hook_default_services_endpoint().
 */
function mymodule_default_services_endpoint() {
  watchdog('mymodule', __FUNCTION__, array(), WATCHDOG_NOTICE, 'link');
  $endpoint = new stdClass();
  $endpoint->disabled = FALSE;  //Edit this to true to make a default endpoint disabled initially
  $endpoint->api_version = 3;
  $endpoint->name = 'mymodule_rest_api_v1';
  $endpoint->server = 'rest_server';
  $endpoint->path = 'api/mymodule/v1';
  $endpoint->authentication = array();
  $endpoint->server_settings = array(
    'formatters' => array(
      'json' => TRUE,
      'bencode' => FALSE,
      'jsonp' => FALSE,
      'php' => FALSE,
      'xml' => FALSE,
    ),
    'parsers' => array(
      'application/json' => TRUE,
      'text/xml' => TRUE,
      'application/vnd.php.serialized' => FALSE,
      'application/x-www-form-urlencoded' => FALSE,
      'application/xml' => FALSE,
      'multipart/form-data' => FALSE,
    ),
  );
  $endpoint->resources = array();
  $endpoint->debug = 0;
  return array('mymodule'=>$endpoint);
}

我删除了此服务的UI构建定义，并且可以看到它已从代码中成功重新创建，另外，当我访问'api / mymodule / v1 /'时，我看到消息'Services Endpoint'mymodule_rest_api_v1“已成功安装。'，所以我知道hook_default_services_endpoint和hook_ctools_plugin_api正常工作。

无论出于何种原因，我都无法将mymodule_services_resources中定义的任何路径识别为有效。我删除了所有访问限制，多次清除缓存 - 总是，当我点击任何以'test'结尾的url时，我最终找不到404（例如https://[my-domain]/api/mymodule/v1/test和https://[my-domain]/api/mymodule/v1/test/1 “未找到：无法找到资源测试。”）。

任何建议都将受到赞赏。

想出来。发布回原因，以防万一其他人遇到过这种情况。

hook_services_resources声明模块提供的资源。它不做的是启用这些资源。回到我的服务端点的资源选项卡下，我发现“test”可用作可以公开的新资源。更重要的是，它没有启用。

启用它并将其导出到代码后，我能够将mymodule_default_services_endpoint的内容更改为：

function mymodule_default_services_endpoint() {
  watchdog('mymodule', __FUNCTION__, array(), WATCHDOG_NOTICE, 'link');
  $endpoint = new stdClass();
  $endpoint->disabled = FALSE; /* Edit this to true to make a default endpoint disabled initially */
  $endpoint->api_version = 3;
  $endpoint->name = 'mymodule_rest_api_v1';
  $endpoint->server = 'rest_server';
  $endpoint->path = 'api/mymodule/v1';
  $endpoint->authentication = array(
    'services' => 'services',
  );
  $endpoint->server_settings = array(
    'formatters' => array(
      'json' => TRUE,
      'bencode' => FALSE,
      'jsonp' => FALSE,
      'php' => FALSE,
      'xml' => FALSE,
    ),
    'parsers' => array(
      'application/json' => TRUE,
      'text/xml' => TRUE,
      'application/vnd.php.serialized' => FALSE,
      'application/x-www-form-urlencoded' => FALSE,
      'application/xml' => FALSE,
      'multipart/form-data' => FALSE,
    ),
  );
  $endpoint->resources = array(
    'test' => array(
      'operations' => array(
        'retrieve' => array(
          'enabled' => '1',
        ),
        'index' => array(
          'enabled' => '1',
        ),
      ),
    ),
  );
  $endpoint->debug = 0;
  return array('mymodule' => $endpoint);
}

现在我收到了我认为可以处理的身份验证错误。希望这有助于某人。
