使用Soroban Python SDK发送付款
#python #soroban #sorobanathon #stellar

在我的previous post中，我向您展示了如何使用Soroban Python SDK部署和调用Soroban Smart合同。在这篇文章中，我们将使用Soroban Python SDK将付款从一个帐户发送到另一个帐户。

准备

首先，创建2个Futurenet帐户，一个作为发件人，另一个作为接收器。在Stellar Laboratory创建帐户，并确保为其提供资金。

我将在本指南中使用的帐户：

  • 发送者帐户： 
Public Key: GDVHH3WBEXOBQMK3FLIWTCRQTC3RQFG7JJXI65IVIJYCU6LXFHPB4MHN
Secret Key: SD45JGK4S6NCORR6GK66BBRDWNDU322ZT5RQK6RT6D2T7HNFYK3M63DS
  • 接收帐户： 
Public Key: GAZK3F5U26FIRD6RHMH34LT7N6I4BYCV4K3LBMVPFCMIYSAHLHCPV3EL
Secret Key: SANHLH2IOJMJIHE7XA6VG64GOIQRWDVXD4A77LDW2JAAWHOAZMRVBM3S

然后，我们要使用的Python脚本是Soroban Python SDK Examples Github Repository的koude0。这些示例由overcat（Soroban Python SDK的维护者）撰写。

发送付款

要发送合同，打开soroban_payment.py文件，您可以调整以下参数：

alice_kp = Keypair.from_secret(
    "SD45JGK4S6NCORR6GK66BBRDWNDU322ZT5RQK6RT6D2T7HNFYK3M63DS"
)  # GDVHH3WBEXOBQMK3FLIWTCRQTC3RQFG7JJXI65IVIJYCU6LXFHPB4MHN
bob_kp = Keypair.from_secret(
    "SANHLH2IOJMJIHE7XA6VG64GOIQRWDVXD4A77LDW2JAAWHOAZMRVBM3S"
)  # GAZK3F5U26FIRD6RHMH34LT7N6I4BYCV4K3LBMVPFCMIYSAHLHCPV3EL
native_token_contract_id = (
    "d93f5c7bb0ebc4a9c8f727c5cebc4e41194d38257e1d0d910356b43bfc528813"
)

alice_kp-发件人秘密键
bob_kp-接收器秘密键
native_token_contract_id-本地令牌合同ID。您可以调整此功能取决于要发送的资产。

    Int128(1000 * 10**7),  # amount, 1000 XLM

您可以调整此行以调整要发送的资产的数量。请注意，该金额位于stroops中，而stroop是腔内的1000万。

快速简介我之前所做的更改：

  • 发件人帐户：gdvhh3wbexobqmk3fliwtcrqtc3rqfg7jjxi65ivijycu6lxfhpb4mhn
  • 接收帐户：GAZK3F5U26FIRD6RHMH34LT7N6I4BYCV4K3LBMVPFCMIYSAHLHCPV3EL
  • 本地令牌金额：1000 XLM（stroop中的1000.0000000）

使用更改保存soroban_payment.py文件。

在运行脚本之前，我们将使用Soroban-CLI检查每个帐户的本机代币余额。

  • 帐户1： 
$ soroban contract invoke --id d93f5c7bb0ebc4a9c8f727c5cebc4e41194d38257e1d0d910356b43bfc528813 --secret-key SD45JGK4S6NCORR6GK66BBRDWNDU322ZT5RQK6RT6D2T7HNFYK3M63DS --fn balance -- --id GDVHH3WBEXOBQMK3FLIWTCRQTC3RQFG7JJXI65IVIJYCU6LXFHPB4MHN
success
"99999999900"

帐户2：

soroban contract invoke --id d93f5c7bb0ebc4a9c8f727c5cebc4e41194d38257e1d0d910356b43bfc528813 --secret-key SANHLH2IOJMJIHE7XA6VG64GOIQRWDVXD4A77LDW2JAAWHOAZMRVBM3S --fn balance -- --id GAZK3F5U26FIRD6RHMH34LT7N6I4BYCV4K3LBMVPFCMIYSAHLHCPV3EL

所以两个帐户本机代币余额现在都是stroop中的“ 99999999900”。

然后，我们将发送付款，使用此命令发送付款运行：

python soroban_payment.py

输出：

从上方我们可以看到交易是成功。让我们在使用同一命令之前再次检查两个帐户的余额。

  • 发送者帐户： 
$ soroban contract invoke --id d93f5c7bb0ebc4a9c8f727c5cebc4e41194d38257e1d0d910356b43bfc528813 --secret-key SD45JGK4S6NCORR6GK66BBRDWNDU322ZT5RQK6RT6D2T7HNFYK3M63DS --fn balance -- --id GDVHH3WBEXOBQMK3FLIWTCRQTC3RQFG7JJXI65IVIJYCU6LXFHPB4MHN

success
"89999999700"
  • 接收器： 
$ soroban contract invoke --id d93f5c7bb0ebc4a9c8f727c5cebc4e41194d38257e1d0d910356b43bfc528813 --secret-key SANHLH2IOJMJIHE7XA6VG64GOIQRWDVXD4A77LDW2JAAWHOAZMRVBM3S --fn balance -- --id GAZK3F5U26FIRD6RHMH34LT7N6I4BYCV4K3LBMVPFCMIYSAHLHCPV3EL

success
"109999999800"

从上面的结果我们可以从发送者帐户中看到1000xlm（stroop中的10000000000）已发送到接收器帐户。

在这篇博客文章中，我们已经介绍了使用Soroban Python SDK发送付款的步骤。您可以发送自己的付款来修改脚本。
