使用PHP从URL显示JSON响应

我有一个来自包裹跟踪服务的订阅源，我正在尝试将其集成到我的网站中。我有一个网址，可以让我将追踪号码放在最后并获得json响应。我有多个对象，其中包括一些静态信息，如发件人地址和一些信息，我需要使用foreach来处理跟踪过程。使用PHP从URL显示JSON响应

我相信我已经得到了字符串好，但我不知道我是如何显示信息。

这是我到目前为止有：

实例网址：

domain.com/REST_Service/webservice/consignee/SelfshipService.svc/web/Tracking/84941354665

网址返回：

你json字符串没有任何results键（所以我不知道为什么你试图访问results[0]。

你可以使用

$Address1 = $json->Consignee->Address1; 
$Address2 = $json->Consignee->Address2;

检查这个代码：

$s = <<< END 
{ 
    "Agent": null, 
    "Consignee": { 
    "Address1": "25 HEATHFIELD ROAD", 
    "Address2": "SHOLING",

    "Name": "",

    { 
     "Date": "13 Jul 2016", 
     "Status": "Out for delivery",

    }, 
    { 
     "Date": "13 Jul 2016", 
     "Status": "At Delivery location Portsmouth", 
     "Time": "02:24" 
    }, 
    { 
     "Date": "13 Jul 2016", 
     "Status": "At Delivery location Portsmouth", 
     "Time": "02:22" 
    }, 
    { 
     "Date": "12 Jul 2016", 
     "Status": "Arrived At Ryton", 
     "Time": "22:12" 
    }, 
    { 
     "Date": "12 Jul 2016", 
     "Status": "Preparing for despatch",

     "Status": "Consignment details verified", 
     "Time": "13:59" 
    }, 
    { 
     "Date": "14 Jun 2016", 
     "Status": "Shipment prepared by customer", 
     "Time": "11:20" 
    }, 
    { 
     "Date": "02 Jan 2003", 
     "Status": "Collected from Customer", 
     "Time": "09:32" 
    } 
    ], 
    "Weight": 7 
} 
END; 

$json = json_decode($s); 
$Address1 = $json->Consignee->Address1; 
$Address2 = $json->Consignee->Address2; 
echo "Address 1: " . $Address1 . ", Address 2: " . $Address2;

这里是输出：

Address 1: 25 HEATHFIELD ROAD, Address 2: SHOLING

当访问它按你的例子我仍然得到一个错误。注意：尝试在第29行的parcel-tracking.php中获取非对象的属性 –

也许您的字符串不是您在示例中添加的内容？如果您在我的回答确切的代码它的工作原理（点击此处查看：http://sandbox.onlinephpfunctions.com/code/cab3a789c3dfaa70e11e8032e3b37bd3c91df64b） – Dekel

这是我的全码：http://sandbox.onlinephpfunctions.com/code/8b97b4a00708d7ddbfa1c0352ddd1e3d1829a997 如果您转到URL，您将看到输出 –

下面是$ JSON变量和访问与JSON字符串RecursiveIteratorIterator
