返回购物清单对象的数组，对于购物者或具有“建议”标志='Y'的列表
当我手动将令牌添加到$ _GET时，我带着一个空白数组返回。 [{},{}]
但如果我var_dump（$ shopper_list）我得到两个不同的用户列表..它应该只有一个，因为一次登录应该等于一个令牌：
[{},{}]
array(2) {

object(UserShoppingList)#4 (14) {

NULL

我的php页面（get_shopping_lists.php）看起来像这样：
/*
This script is used to return a JSON array of ShoppingList objects.
Those objects can be limited to either only "suggested" ShoppingList names,
or to all of the lists for a single Shopper. So, either the shopper_id or
the boolean "suggested_only" should be set.
*/
if(!isset($_GET['token']) && !isset($_GET['suggested_only'])) {
die('Must pass-in either a \'token\' or \'suggested_only\' flag');
}
if(isset($_GET['token'])) {
$shopper = new Shopper($_GET['token'])
or die('Could not instantiate a new Shopper from the \'token\' passed-in');
$shopper_lists = $shopper->get_lists(true);
echo json_encode($shopper_lists);
}
if(isset($_GET['suggested_only']) && $_GET['suggested_only'] == 'true') {
}
我正在寻找一个购物清单对象数组，要么是购物者（你将一个标记传递给Shopper类的“get_lists”函数），要么是那些具有“建议”的列表“flag ='Y'如果你要传递另一个参数来表示你只想要建议的列表。这些选项中的每一个都会以不同的方式调用框架中的部分。
购物者类别：

关于如何引用购物者列表，如果他们没有列表而不是选择建议，我有点困惑。
我的（oracle11g）数据库中有一些测试列表：
ID SHOPPING_LIST_NAME S SEQUENCE
------- -------------------------------------------------- - --------
3 793d7384fa4fa247d6fae07db104147d0a2dad6e N
1 test amnaik shopping list N
4 kj's shopping list N
5 kj's shopping list from 1384201636 N
6 kj's shopping list from 1384201659 N
7 kj's shopping list from 1384202055 N
8 kj's shopping list from 1384202089 N
2 bonner shopping list N
8 rows selected.
SHOPPING_LIST_ID SHOPPER_ID ITM_CD QUANTITY CHANGE_DA CHANGE_US A O
---------------- ---------- --------- -------- --------- --------- - -
1 2 ABI85MT06 4 28-OCT-13 CUSTOM N N
1 1 STZ28AC1 3 11-NOV-13 CUSTOM Y N
1 1 ABI85MT06 3 11-NOV-13 CUSTOM Y N
1 1 XYZ 1 Y N
2 1 XYZ 1 Y N
4 67 MND44SA01 1 Y N
4 67 MND44SA02 1 Y N
2 67 MND44SA02 1 Y N
1 1 ABCDEF 1 Y N
9 rows selected.
像往常一样，我们将非常感谢任何帮助或建议。谢谢。

根据Shopper类，更新的get_lists函数正在调用db方法：
$rows = $db->get_function('custom.japi_shopper_identity.get_lists_for_shopper(:i_sign_in_token)', $vars);
此方法返回一个数组，我必须假设它是来自oracle db的查询结果。将它转换为一组对象并将其返回给get_shopping_lists.php后，您需要检查以确保此值不为false，因为这是get_lists（）方法调用中的最后一个条件。如果是，则输出某种类型的错误消息（如果这是您的消费者所期望的，可能采用JSON格式）。
至于你想要添加的新东西
对于第一个，在你获取行之后，你将检查以确保$ rows不为空，然后调用一个方法来创建一个列表（大概也是某种类型的customer.japi_shopper ...函数在oracle上侧。
对于第二个，你将用if / else分支逻辑（如果$ suggest == true，获取那些结果;否则，做你正在做的事情......）
