Question

我有来自包裹跟踪服务的Feed，我正在尝试整合到我的网站中。我有一个网址，允许我将跟踪号放在最后并获得json响应。我有多个这样的对象，其中包括一些静态信息，例如发件人地址和一些信息，我需要使用foreach来跟踪跟踪进度。

我相信我的字符串还可以，但我不确定我是如何显示信息的。

这是我到目前为止所做的：

示例网址：

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

网址返回：

    }
  ],

}

当前的PHP：

//set tracking url
$url = "http://www.ocscourier.co.uk/REST_Service/webservice/consignee/SelfshipService.svc/web/Tracking/84941354665";

// create curl resource
$ch = curl_init();

// set url
curl_setopt($ch, CURLOPT_URL, "http://www.ocscourier.co.uk/REST_Service/webservice/consignee/SelfshipService.svc/web/Tracking/84941354665");

//return the transfer as a string
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_USERAGENT, 'Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.8.1.13) Gecko/20080311 Firefox/2.0.0.13');

// $output contains the output string
$output = curl_exec($ch);

// close curl resource to free up system resources
curl_close($ch);

//call api
//$json = file_get_contents($url);
$json = json_decode($output);
$Address1 = $json->results[0]->Consignee->Address1;
$Address2 = $json->results[0]->Consignee->Address2;
echo "Address 1: " . $Address1 . ", Address 2: " . $Address2;

Answer 1

您的json字符串没有results个密钥（因此我不确定您尝试访问results[0]的原因。

你可以使用

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

检查此代码：

$s = <<< END
{
  "Agent": null,
  "Consignee": {
    "Address1": "25 HEATHFIELD ROAD",
    "Address2": "SHOLING",
    "Address3": "",
    "Code": null,
    "Company": "ERIK HANSON",
    "Country": "GREAT BRITAIN",
    "Dept": "",
    "Email": "ERIK.HANSON66@GOOGLEMAIL.COM",
    "Name": "",
    "Phone": "07770320490",
    "Postcode": "SO19 1DL",
    "State": "HANTS",
    "Town": "SOUTHAMPTON"
  },
  "CrossIdx": "",
  "Error": null,
  "NonDel": null,
  "POD": {
    "Date": "13 Jul 2016",
    "Status": "Harnett",
    "Time": "09:17"
  },
  "Pieces": 1,
  "PosErr": 0,
  "Tracks": [
    {
      "Date": "13 Jul 2016",
      "Status": "Out for delivery",
      "Time": "07:10"
    },
    {
      "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",
      "Time": "14:00"
    },
    {
      "Date": "12 Jul 2016",
      "Status": "Scanned into OCS HEATHROW LONDON",
      "Time": "13:59"
    },
    {
      "Date": "12 Jul 2016",
      "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;

这是输出：

Address 1: 25 HEATHFIELD ROAD, Address 2: SHOLING

Answer 2

下面是$ json变量中的json字符串，并使用RecursiveIteratorIterator访问

<强> 实施例

$json='{
  "Agent": null,
  "Consignee": {
    "Address1": "25 HEATHFIELD ROAD",
    "Address2": "SHOLING",

    {

    {
      "Date": "02 Jan 2003",
      "Status": "Collected from Customer",
      "Time": "09:32"
    }
  ],
  "Weight": 7
}';
 $jsonIterator = new RecursiveIteratorIterator(
 new RecursiveArrayIterator(json_decode($json, TRUE)),
 RecursiveIteratorIterator::SELF_FIRST);

foreach ($jsonIterator as $key => $val) {
    if(is_array($val)) {
        echo "$key:\n</br>";
    } else {
        echo "$key => $val\n";
    }
}
