bitcoinTestnet 網路返回一個主網地址

我正在使用此程式碼從擴展公鑰中獲取新地址：

   $index = 97;
   $change = false;
   $key = HierarchicalKeyFactory::fromExtended($tpubaddress, NetworkFactory::bitcoinTestnet());
   $path = ($change ? '1' : '0').'/'.$index;
   $child_key = $key->derivePath($path);
   $address = new PayToPubKeyHashAddress($child_key->getPublicKey()->getPubKeyHash()))->getAddress();
   echo $address;

這導致了一個地址，如

15fuesDBKKnEMnrZz3mT9fxbm7dkjwDN3z

這是一個主網 P2PKH 地址。

有沒有辦法讓它給我一個測試網 P2PKH 地址（例如mjKxMDjShxKS5LymC43EmctDoB5Sg3n6UZ）？

這打破了我使用來自錯誤網路的地址 b/c 創建原始交易的嘗試。如果不是，我應該在他們的 github 項目上報告這個問題嗎？

下面的程式碼解決了這個問題。問題是我使用的類沒有在 bitwasp 比特幣對像上設置網路。程式碼來自自由節點。
