php給客戶端返回數據注意。

親身測試：

返回的時候不要直接返回字符串，要用數組的方式返回數據客戶端才能接收。 看代碼。

 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 //     $logger->trace("新增訂單信息===$postParam");
15     $result = array(
16             "userID" => $userID,
17             "orderID" => $orderID,
18             "typeSale" => $typeSale,
19             "typeClient" => $typeClient,
20             "criteoSourceVal" => $criteoSourceVal
21     );
22 //     echo json_encode("asdf");  這種方式返回數據網頁能接收，curl命令能接收，可是app接收爲null
23     echo json_encode($result);
24 }
25 
26 main();
