如何在 php 中访问私有作用域命名空间数组数据？

Question

这里是数组数据：

我正在尝试弄清楚如何访问其中一些变量。

例如，我怎样才能做到这一点：

$bitcoin_address = [address:Coinbase\Wallet\Resource\Address:private];
$type = [type:Coinbase\Wallet\Resource\Transaction:private];

我知道您不能访问私有范围，但是有什么办法可以解决这个问题吗？如果没有更好的方法，我可以抓取数据吗？

谢谢。

Answer 1

是的，访问数据的最佳方式是使用 decodeLastResponse 函数。

它允许在这些数组中提取您需要的所有数据。

 $address = $client->getAccountAddress($account, $addressId);   
 $transactions = $client->getAddressTransactions($address);
 $transactions = $client->decodeLastResponse();
 echo var_dump($transactions['data']);

Answer 2

几乎所有这些私有属性都有公共getter（允许您访问私有属性的公共方法）。

$bitcoinAddresses = [];
$types = [];

foreach ($resourceCollection->all() as $transaction) {
    $bitcoinAddresses[] = $transaction->getTo()->getAddress();
    $types[] = $transaction->getType();
}

如果你访问coinbase/coinbase-php repo，你可以在那里看到源代码。您描述的所有类都有所有的属性和方法。

Answer 3

你需要像这样调用函数decodeLastResponse：

$addresses = $client->getAccountAddresses($account)    
$addresses = $client->decodeLastResponse();
