我有一个dynamodb表,其中"feed_guid"作为全局二级索引.我想查询该表中的一组feed_guid.由于"feed_guid"不是我的主键,所以我不能使用getBatchItem.当我尝试以下方法时,我收到此错误"KeyConditionExpression中使用的无效运算符:OR".

    $options = array(
                'TableName' => 'feed',
                    'IndexName' => 'GuidIndex',
                    'KeyConditionExpression' => 'feed_guid = :v_guid1 or feed_guid = :v_guid2',

                    'ExpressionAttributeValues' =>  array (
                        ':v_guid1' => array('S' => '8a8106e48bdbe81bf88d611f4b2104b5'),
                        ':v_guid2' => array('S' => '19cab76242a6d85717de64fe4f8acbd4')
                    ),
                    'Select' => 'ALL_ATTRIBUTES',
                );
                $response = $dynamodbClient->query($options);

我有一个具有以下项目结构的 AWS DynamoDb 购物车表 -

{
  "cart_id": "5e4d0f9f-f08c-45ae-986a-f1b5ac7b7c13",
  "user_id": 1234,
  "type": "OTHER",
  "currency": "INR",
  "created_date": 132432423,
  "expiry": 132432425,
  "total_amount": 90000,
  "total_quantity": 2,  
  "items": [
    {
      "amount": 90000,
      "category": "Laptops",
      "name": "Apple MacBook Pro",
      "quantity": 1
    }
  ]
}

{
  "cart_id": "12340f9f-f08c-45ae-986a-f1b5ac7b1234",
  "user_id": 1234,
  "type": "SPECIAL",
  "currency": "INR",
  "created_date": 132432423,
  "expiry": 132432425,
  "total_amount": 1000,
  "total_quantity": 2,  
  "items": [
    {
      "amount": 1000,
      "category": "Special",
      "name": "Special Item",
      "quantity": 1
    }
  ]
}

该表将cart_id作为主键、
user_id作为索引或 GSI、
type作为索引或 GSI。 …
