py-algorand-sdk 相当于“./sandbox 目标账户列表”

问题描述

TLDR; 我在沙箱中运行 algorand PrivateNet。我想知道如何使用适用于 algorand 的 Python SDK 返回此网络上帐户的地址和余额。

更长的版本； 到目前为止，我一直在使用 "./sandBox goal account list" 在 Bash 中查找帐户地址和帐户余额，返回：

我尝试使用下面概述的 algod 和 v2client.indexer 模块，但我的代码（原始 3 +1）列出了上面列出的 3 个帐户，而不是 4 个。代码：

    #imports
    from algosdk import algod,v2client
    
    # instatiate AlgodClient
    def connect_to_network():
        algod_address = "http://localhost:4001"
        algod_token = "aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa"
        algod_client = algod.AlgodClient(algod_token,algod_address)
        return algod_client 
    
    # instantiate IndexClient
    def indexer():
        indexer_token = ""
        indexer_address = "http://localhost:8980"
        indexer_client = v2client.indexer.IndexerClient(indexer_token,indexer_address)
        return indexer_client
    
    # returns all account details from indexer
    def account_details():
        raw_details = indexer().accounts() # <-- I think the error is here because this returns 4 addresses.
        account_details = []
        for details in raw_details["accounts"]:
            account_details.append({"address":details["address"],"amount": details["amount"]})
        return account_details
    
    # returns the amount in each account
    def account_amounts(account_address):
        return connect_to_network().account_info(account_address)
    
    # returns account address and amount for each account
    for detail in account_details():
        print(account_amounts(detail["address"])["address"])
        print(account_amounts(detail["address"])["amount"])

返回：

1. 如何使用 py-algorand-sdk 复制 "./sandBox goal account list"？
2. （额外问题）与 Bash 相比，当我使用 SDK 时出现的这个额外的神秘“帐户”是什么？

解决方法

出现上述问题是因为与 ./sandbox goal accounts list 一样，我试图返回我在 KMD 本地拥有密钥的帐户，但我对索引器的调用 raw_details = indexer().accounts() 返回了网络上的所有帐户。

要解决此问题，请从 v2client.indexer 库导入 wallet 模块，而不是导入和使用 algosdk 模块。这些是必要的导入：

from algosdk import algod,kmd,wallet

然后设置与algod、kmd和您的钱包的连接：

# instatiate AlgodClient
def connect_to_network():
    algod_address = "http://localhost:4001"
    algod_token = "aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa"
    algod_client = algod.AlgodClient(algod_token,algod_address)
    return algod_client 

# instantiate KMDClient <--- this is used as a parameter when instantiating the Wallet Class.
def key_management():
    kmd_address = "http://localhost:4002"
    kmd_token = "aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa"
    kmd_client = kmd.KMDClient(kmd_token,kmd_address)
    return kmd_client

#get wallet details
def wallet_details():
    wallet_name = 'unencrypted-default-wallet'
    password = ""
    kmd_client = key_management()
    return wallet.Wallet(wallet_name,password,kmd_client)

您现在可以返回本地保存在 KMD 中的帐户地址：

keys = wallet_details().list_keys()

现在您有了可以查询的地址，使用 algod 客户端返回每个地址中持有的（微）Algo 数量。
