php给客户端返回数据注意。

 1 <?php
 2 require_once("../base.php");
 3 
 4 function add_order(){
 5 //     echo "asdfasfd";
 6 //     exit();
 7 //     $logger = Logger::getRootLogger();
 8 //     $postParam = RequestUtil::postParam("user_id","order_id","type_sale","type_client");
 9     $userID = $_POST[‘user_id‘] ;
10     $orderID = $_POST[‘order_id‘] ;
11     $typeSale = $_POST[‘type_sale‘] ;
12     $typeClient = $_POST[‘type_client‘] ;
13     $criteoSourceVal = $_POST[‘criteo_source_val‘];
14 //     $logger->trace("新增订单信息===$postParam");
15     $result = array(
16             "userID" => $userID,
17             "orderID" => $orderID,
18             "typeSale" => $typeSale,
19             "typeClient" => $typeClient,
20             "criteoSourceVal" => $criteoSourceVal
21     );
22 //     echo json_encode("asdf");  这种方式返回数据网页能接收，curl命令能接收，但是app接收为null
23     echo json_encode($result);
24 }
