我正在开发一个php购物清单功能/ api

返回一个购物清单对象数组,用于购物者,或者具有“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) {
  [0]=>
  object(UserShoppingList)#4 (14) {
    ["sign_in_token":protected]=>
    NULL
    ["Shopper":protected]=>
    NULL
    ["ID":protected]=>
    string(1) "4"
    ["SHOPPING_LIST_NAME":protected]=>
    string(18) "kj's shopping list"
    ["SUGGESTION":protected]=>
    string(1) "N"
    ["SEQUENCE":protected]=>
    NULL
    ["ShoppingListItem":protected]=>
    NULL
    ["api_url":protected]=>

      ["ID"]=>
      NULL
    }
    ["alias_db_to_PHP":"Base":private]=>
    array(0) {
    }
    ["alias_PHP_to_db":"Base":private]=>
    array(0) {
    }
  }
  [1]=>
  object(UserShoppingList)#5 (14) {
    ["sign_in_token":protected]=>
    NULL
    ["Shopper":protected]=>
    NULL
    ["ID":protected]=>
    string(1) "2"
    ["SHOPPING_LIST_NAME":protected]=>
    string(20) "bonner shopping list"
    ["SUGGESTION":protected]=>
    string(1) "N"
    ["SEQUENCE":protected]=>
    NULL
    ["ShoppingListItem":protected]=>
    NULL
    ["api_url":protected]=>
    NULL
    ["table":"Base":private]=>
    string(23) "jfw_shopping_list_names"
    ["procedure":"Base":private]=>
    NULL
    ["procedure_args":"Base":private]=>
    NULL
    ["keys":"Base":private]=>
    array(1) {
      ["ID"]=>

    }
    ["alias_db_to_PHP":"Base":private]=>
    array(0) {
    }
    ["alias_PHP_to_db":"Base":private]=>
    array(0) {
    }
  }
}

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') {

}

我想要返回一个购物清单对象数组,要么是购物者(在那里你将一个标记传递给Shopper类的“get_lists”函数),要么是具有“建议”标志的列表= ‘Y’如果你要通过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：

// Most objects in this framework are populated by calling the constructor, but
// this one has a variety of entry points. They don't do any sanity checking
// with eachother, so you can have $user->create and $user->register refer to

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.

我在我的(oracle11g)数据库中得到了一些测试列表：

像往常一样,任何帮助或建议将不胜感激.谢谢.

解决方法:

基于该Shopper类,您更新的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,我必须假设该数组来自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,输出某种类型的错误消息(可能是JSON格式,如果这是您的消费者所期望的).

至于你想要添加的新东西

>如果他们没有列表,则自动创建一个列表
>获取建议的清单

对于第一个,在您获取行之后,您将检查以确保$rows不为空,然后调用方法来创建列表(可能还有某种类型的customer.japi_shopper …函数在oracle端.

对于第二个,你将使用if / else分支逻辑(如果$suggest == true,获取结果;否则,执行你已经在做的事情……)
