Question

请给我你的建议。

以下网址提供了jsonp格式的数据： http://demos.kendoui.com/service/Products

然而，只有我做的改变是使用我自己的url指向简单的php获取jsonp数据如下：

<?php
header('Vary: Accept-Encoding');
header('Connection: Keep-Alive');
header('Content-Encoding: gzip');
header('Content-Length: 1743');
header('Content-Type: application/x-javascript; charset=utf-8');
echo gzencode('callback([{"ProductID":2,"ProductName":"Chang","UnitPrice":19,"UnitsInStock":17,"Discontinued":false}])');
?>

HTML源代码如下：

<!DOCTYPE html>
<html>
<head>
    <title>ESS Software Inventory</title>
    <meta charset="utf-8">
    <link href="./kendoui/content/shared/styles/examples-offline.css" rel="stylesheet">

必须使用这个：因为返回的jsonp应该有动态回调名称

parse_str（$ _ SERVER [ 'QUERY_STRING']）;回声“$ callback”。 “（[{ “产品ID”：1， “产品名称”： “柴”， “单价”：18， “库存量”：39， “停产”：假}，{ “产品ID”：2 “产品名称”：“常“，”UnitPrice“：19，”UnitsInStock“：17，”Discontinued“：false}，{”ProductID“：3，”ProductName“：”Aniseed Syrup“，”UnitPrice“：10，”UnitsInStock“：13，”停止使用“：false}，{”ProductID“：4，”ProductName“：”Chef Anton \ u0027s Cajun Seasoning“，”UnitPrice“：22，”UnitsInStock“：53，”Discontinued“：false}]）';
