【问题描述】：
我正在使用 WooCommerce API 开发一个小型 Web 应用程序。此应用程序需要从 wordpress/woocommerce 中提取订单信息。
我能够很好地提取其中一些信息，但在其他方面遇到问题（这完全是另一个问题。）
woocommerce REST api 中的数据以多维数组的形式返回。
这是一个单一订单的例子：
array (size=2)
'order' =>
array (size=30)
'id' => int 22
'order_number' => int 22

出于安全原因，我刚刚删除了带有哈希的任何地方的数据。
所以我需要遍历所有订单以输出特定信息。通过使用此循环，我可以轻松访问主“订单”数组中的字符串：
$orders = $connect->orders->get(22);
foreach( $orders as $order ) {
foreach( $order as $value ) {
echo $value["order_number"];
$value["total"];
}
}
这个循环在几秒钟内运行并输出数据。
但是，当我从主订单数组中的“line_items”数组中输出数据时：
1) 如果不指定订单 ID，我似乎无法做到这一点，否则我会得到一个未定义的索引：订单和为每个循环的订单项提供的无效参数。
为了克服我已将此行添加到主循环以从“line_items”数组中获取数据：
$line_items = $connect->orders->get($value["order_number"]);
$line_items = $orders['order']['line_items'];
然后我对此运行 foreach 以输出“line_items 数组”中的值
foreach($line_items as $item) {
echo $item['name'];
echo $item['quantity']';
}
这样可以，但是以这种方式输出“line_items”会使页面加载速度非常慢。循环 6 个订单大约需要 40 秒。
如果没有这一行：
$line_items = $connect->orders->get($value["order_number"]);
页面在大约 5 秒内呈现。
我的问题是：这是访问“line_items”数组的最佳方式吗？
以下是输出订单信息的完整代码，包括订单项。
$orders = $connect->orders->get(22);
foreach( $orders as $order ) {
foreach( $order as $value ) {
echo $value["order_number"];
$value["total"];
//get line items based on current order id - this is the slow bit!
$line_items = $connect->orders->get($value["order_number"]);
$line_items = $orders['order']['line_items'];
//loop through line items
foreach($line_items as $item) {
echo $item['name'];
echo $item['quantity']';
}
}
}
【问题讨论】：
-
页面输出了多少数据？ 2K 还是 40M 字节？
-
这听起来真的很愚蠢。如何准确地告诉您输出了多少数据？
-
一种方法是查看网页的源代码（Mozilla 系列浏览器中的 ctrl-U），将其复制并粘贴到编辑器中，然后保存并查看文件大小。
-
页面大小为 18KB。是的，get 方法正在调用来自 wordpress 站点的订单列表。它来自 woocommerce rest api：woothemes.github.io/woocommerce-rest-api-docs/…
