微信小店的後台中提供了訂單查詢功能，但只有商家能使用，如果用戶需要查看自己的訂單，則要使用微信小店的接口來開發實現。這需要用到根據訂單狀態/創建時間獲取訂單詳情的接口。
根據訂單狀態/創建時間獲取訂單詳情的接口如下。
https:// api.weixin.qq.com/merchant/order/getbyid?access_token=ACCESS_TOKEN
該接口的POST數據格式如下，參數說明如表10-3所示。
{
"status": 2,
"begintime": 1397130460,
"endtime": 1397130470
}

表10-4 訂單查詢接口返回內容的參數說明
為了在微信中實現訂單查詢，需要先將一個菜單設置為「訂單查詢」，該菜單的類型為「CLICK」，key值為「WDDD」。
菜單的實現代碼如下。
1 require_once('weixin.class.php');
2 $weixin = new class_weixin;
3
4 $button = array('type' => "view",
5 'name' => urlencode("微信小店"),
6 'url' => "http:// mp.weixin.qq.com/bizmall/mallshelf?id=&t=mall/
list&biz=MzANDQxNDUwNQ==&shelf_id=1&showwxpaytitle=1#wechat_
redirect",
7 );
8 $button = array('name' => urlencode("更多"),
9 'sub_button' => array(array('type' => "click",
10 'name' => urlencode("我的訂單"),
11 'key' => urlencode("WDDD")
12 ),
13 )
14 );
15 $menu = urldecode(json_encode(array('button' => $button)));
16 var_dump($weixin->create_menu($menu));
當用戶點擊「我的訂單」時，微信接口將接收到這一點擊事件通知，並且調用微信小店的訂單查詢接口來查詢當前用戶的訂單信息，實現代碼如下。
1 // 接收事件消息
2 private function receiveEvent($object)
3 {
4 $content = "";
5 switch ($object->Event)
6 {
7 case "subscribe":
8 $content = "歡迎關注方倍工作室";

17 $orderArr = $weixin->get_detail_by_filter("{}");
18 if ($orderArr["errcode"] == -1){
19 $weixin->send_custom_message($openid, "text", "系統繁忙，
請稍後再試！");
20 }

117 }
118 }else{
119 $result = $this->transmitText($object, $content);
120 }
121 return $result;
122 }
在上述代碼中與訂單查詢通知相關部分的簡要說明如下。
第13行：判斷是否收到訂單查詢事件通知。
第14～17行：引用微信小店SDK，獲取當前的所有訂單信息。
第18～23行：用於查詢訂單接口的異常判斷。
第24～96行：遍歷訂單詳細中的所有訂單列表，將當前用戶的訂單內容填充到微信圖文消息中。
第98～102行：使用客服接口將訂單詳情通過圖文消息方式發送。
我的訂單查詢實現效果如圖10-28所示。
