Question

我正在使用该软件包：https://packagist.org/packages/gavroche/ups-api

当我运行时，我从Laravels异常处理程序中得到一些奇怪的行为：

$tracking = new \UPS\Tracking(
        'KEY', 'USERNAME', 'PASS'
        );

$shipment = $tracking->track('TRACKING NUMBER HERE');

foreach($shipment->Package->Activity as $activity) {
    var_dump($activity->ActivityLocation->Address->City);
}

有趣的是，城市是var_dumped但是laravels异常处理程序，在同一口气中，说Undefined属性：stdClass :: $ City。

以下是$活动对象之一的vardump：

object(stdClass)[518]

  public 'ActivityLocation' => 

    object(stdClass)[519]

      public 'Address' => 

        object(stdClass)[520]

          public 'City' => string 'CLEVELAND' (length=9)

          public 'StateProvinceCode' => string 'TN' (length=2)

          public 'PostalCode' => string '37311' (length=5)

          public 'CountryCode' => string 'US' (length=2)

      public 'Code' => string 'M4' (length=2)

      public 'Description' => string 'RECEPTION' (length=9)

      public 'SignedForByName' => string 'HICKMAN' (length=7)

  public 'Status' => 

    object(stdClass)[521]

      public 'StatusType' => 

        object(stdClass)[522]

          public 'Code' => string 'D' (length=1)

          public 'Description' => string 'DELIVERED' (length=9)

      public 'StatusCode' => 

        object(stdClass)[523]

          public 'Code' => string 'KB' (length=2)

  public 'Date' => string '20130426' (length=8)

  public 'Time' => string '085500' (length=6)

$ activity-＆gt; ActivityLocation-＆gt;地址对象laravel中的任何属性都会出现问题。但是，我可以请求$ activity-＆gt; Status-＆gt; StatusType-＆gt;说明并且没有问题。

常规for循环修复了该问题。似乎是增加php的foreach（）的一些问题。

for ($i=0; $i < (count($shipment->Package->Activity) - 1); $i++) { 
    var_dump($shipment->Package->Activity[$i]->ActivityLocation->Address->City);
}

您对此并不清楚，但是您是否尝试以

方式访问此内容

$activity->ActivityLocation->Address->City ?

您离开问题的$activity部分并使用$City而不是City，我不确定这是否是故意的

对象具有实际定义的“未定义属性”
