ChargeBee發票PHP API請求，訪問$發票

Question

我通過PHP做如下要求ChargeBee的API： -

ChargeBee_Environment::configure("chargebee-test","test_uybGuyguyguykynkgYgkfvyt"); 
$all = ChargeBee_Invoice::all(array(
    "customer_id" => 2uyg23inuy2g3ou, 
    "limit"  => 5, 
    "status[is]" => "paid", 
    "total[lte]" => 1000, 
    "sortBy[asc]" => "date")); 

foreach($all as $entry){ 
    $invoice = $entry->invoice(); 
    echo'<pre>'; 
    print_r($invoice); 
    echo'</pre>'; 
} 

到$entry->invoice()每個調用返回具有以下結構的對象：

ChargeBee_Invoice Object 
(
    [allowed:protected] => Array 
     (
      [0] => id 
      [1] => poNumber 
      [2] => customerId 
      [3] => subscriptionId 
     ) 

    [_values:protected] => Array 
     (
      [id] => 4 
      [customer_id] => 2uyg23inuy2g3ou 
      [subscription_id] => 2uyg23inuy2g3ou 
      [line_items] => Array 
       (
        [0] => Array 
         (
          [id] => li_2uyg23inuy2g3ou 
          [date_from] => 1484106779 
         ) 

       ) 

      [sub_total] => 200 
      [linked_payments] => Array 
       (
        [0] => Array 
         (
          [txn_id] => txn_2uyg23inuy2g3ou 
          [applied_amount] => 200 
          [applied_at] => 1484106781 
          [txn_status] => success 
          [txn_date] => 1484106781 
          [txn_amount] => 200 
         ) 

       ) 

    [_subTypes:protected] => Array 
     (
      [line_items] => ChargeBee_InvoiceLineItem 
      [discounts] => ChargeBee_InvoiceDiscount 
      [taxes] => ChargeBee_InvoiceTax 
     ) 

) 

（我減少了上面的數據量，因爲返回的請求在這裏顯示的時間很長）

這是我陷入困境的地方，我如何能夠extrac來自對象的數據？

我已經嘗試以下操作： -

foreach($all as $entry){ 
    $invoice = $entry->invoice(); 
    echo'<pre>'; 
    print_r($invoice->allowed); 
    echo'</pre>'; 
} 

foreach($all as $entry){ 
    $invoice = $entry->invoice(); 
    echo'<pre>'; 
    print_r($invoice->allowed()); 
    echo'</pre>'; 
} 

foreach($all as $entry){ 
    $invoice = $entry->invoice(); 
    echo'<pre>'; 
    print_r($invoice->ChargeBee_Invoice); 
    echo'</pre>'; 
} 

foreach($all as $entry){ 
    $invoice = $entry->invoice(); 
    echo'<pre>'; 
    print_r($invoice->ChargeBee_Invoice()); 
    echo'</pre>'; 
} 

foreach($all as $entry){ 
    $invoice = $entry->invoice(); 
    echo'<pre>'; 
    print_r($invoice['ChargeBee_Invoice']); 
    echo'</pre>'; 
} 

foreach($all as $entry){ 
    $invoice = $entry->invoice(); 
    echo'<pre>'; 
    print_r($invoice['allowed']); 
    echo'</pre>'; 
} 

我也試圖用下面的代碼上面的許多變化： -

foreach($all as $entry){ 
    $invoice = $entry->invoice(); 
    foreach($invoice as $cinvoice) { 
     echo'<pre>'; 
     print_r($cinvoice->allowed); 
     echo'</pre>'; 
    } 
} 

但一切我嘗試剛剛返回： -

Fatal error: Uncaught exception 'Exception' with message 'Unknown property 

任何幫助或推動正確的方向將非常讚賞

Answer 1

從docs您可以看到發票對象的公共屬性。

要訪問他們，你只是，例如：

echo "<pre>"; 
foreach($all as $entry){ 
    $invoice = $entry->invoice(); 
    echo "Invoice #{$invoice->customerId} for a total of {$invoice->amountDue} has status '{$invoice->status}'"\n; 
} 
echo "</pre>"; 

測試出來，並檢查文檔的其他可用的屬性。

要直接訪問保護屬性。訪問對象中的數據ChargeBee_Invoice由神奇方法__get（）（source code of parent class ChargeBee_Model）實現。可查看的可用屬性列表this page。 此代碼可以幫助您開始：

<?php 
    foreach ($all as $entry) 
    { 
     /* Get next invoice */ 
     $invoice = $entry->invoice(); 

     /* Get properties from invoice */ 
     echo $invoice->id; 
     echo $invoince->subscription_id; 

     /* And so on */ 
    } 
?>
