給定 Solana 錢包地址，我想驗證已確認的每筆交易以檢查其他資訊，例如接收者（或發送者）和發送（或接收）的金額。所以，像往常一樣，我搜索了一些 API。我發現了以下內容：
- 茄子
- 索拉納
之后，我去看看他們提供了哪些方法。似乎接近我希望的是 solana_client.get_confirmed_signature_for_address2（在 1 中可用），但是我的結果與其檔案顯示的結果不符。這里是：
from solana.rpc.api import Client
solana_client = Client("https://api.devnet.solana.com")
solana_client.get_signatures_for_address("2AQdpHJ2JpcEgPiATUXjQxA8QmafFegfQwSLWSprPicm", limit=1)
我明白了：
{'jsonrpc': '2.0', 'result': [], 'id': 1}
但是，我應該得到它的最后一個簽名，這似乎是這樣的：
4SNQ4h1vL9GkmSnojQsf8SZyFvQsaq62RCgops2UXFYag1Jc4MoWrjTg2ELwMqM1tQbn9qUcNc4tqX19EGHBqC5u
無論如何，我們可以使用 SolanaBeach 并檢查. 此外，如果我們按照檔案說明進行編碼：
from solana.rpc.api import Client
solana_client = Client("https://api.devnet.solana.com")
solana_client.get_signatures_for_address("Vote111111111111111111111111111111111111111", limit=1)
我明白了：
{'jsonrpc': '2.0', 'result': [{'blockTime': 1637328065, 'confirmationStatus': 'finalized', 'err': {'InstructionError': [0, {'Custom': 0}]}, 'memo': None, 'signature': '5yaeqDRCHWCGQMqNWhq3g6zqw63MBkri9i86hjK954YFFvnG2VCQJfszXsozDVUJbePagJieAzwsSY5H7Xd1jJhC', 'slot': 95301596}], 'id': 1}
奇怪的是“Vote111...11”似乎不是地址。盡管如此，我得到了預期的結果，這是一個簽名，即使 Solana Explorer 找不到這樣的簽名......
請告訴我要解決什么問題。我不知道該怎么做。我什至試圖檢查是否所有 Solana Explorer 都有自己的 API，但他們沒有。可能是因為 Solana 已經分享了它，對吧？
編輯
好吧，看來我需要輸入“帳戶地址作為 base-58 編碼字串”，因此地址變為：HLiBGYYxaQqQx8UTPHEahqcd7aZjkDgN3bihc3hYM3SDUBGU9LFrQSnx9eje。
我也這樣做了，我得到：
{'jsonrpc': '2.0', 'error': {'code': -32602, 'message': 'Invalid param: WrongSize'}, 'id': 1}

我已經實作了在 javaScript 上獲取給定地址的所有交易的功能，這可能會對您有所幫助。
async getTransactionsOfUser(address, options, connection) {
console.log({ address, options });
try {
const publicKey = new PublicKey(address);
const transSignatures =
await connection.getConfirmedSignaturesForAddress2(publicKey, options);
console.log({ transSignatures });
const transactions = [];
for (let i = 0; i < transSignatures.length; i ) {
const signature = transSignatures[i].signature;
const confirmedTransaction = await connection.getConfirmedTransaction(
signature,
);
if (confirmedTransaction) {
const { meta } = confirmedTransaction;
if (meta) {
const oldBalance = meta.preBalances;
const newBalance = meta.postBalances;
const amount = oldBalance[0] - newBalance[0];
const transWithSignature = {
signature,
...confirmedTransaction,
fees: meta?.fee,
amount,
};
transactions.push(transWithSignature);
}
}
}
return transactions;
} catch (err) {
throw err;
}
}

問題不是module，也不function但endpoint。
在Solana Doc 中，我找到endpoint了mainnet：
https://api.mainnet-beta.solana.com
https://solana-api.projectserum.com
它給出了所有的價值。
在其他頁面你可以看到
devnet僅playground用于測驗和tokens are not realtestnet只為stress test和tokens are not real
#Devnet#
- Devnet serves as a playground for anyone who wants to take Solana for a test drive, as a user, token holder, app developer, or validator.
- Application developers should target Devnet.
- Potential validators should first target Devnet.
- Key differences between Devnet and Mainnet Beta:
- Devnet tokens are not real
- Devnet includes a token faucet for airdrops for application testing
- Devnet may be subject to ledger resets
- Devnet typically runs a newer software version than Mainnet Beta
#Testnet#
-Testnet is where we stress test recent release features on a live cluster, particularly focused on network performance, stability and validator behavior.
- Testnet tokens are not real
- Testnet may be subject to ledger resets.
- Testnet includes a token faucet for airdrops for application testing
- Testnet typically runs a newer software release than both Devnet and Mainnet Beta
測驗的最小作業示例：
from solana.rpc.api import Client
all_addresses = [
'2AQdpHJ2JpcEgPiATUXjQxA8QmafFegfQwSLWSprPicm',
'Vote111111111111111111111111111111111111111',
'fake address',
]
#endpoint = 'https://api.devnet.solana.com' # probably for `developing`
#endpoint = 'https://api.testnet.solana.com' # probably for `testing`
endpoint = 'https://api.mainnet-beta.solana.com'
#endpoint = 'https://solana-api.projectserum.com'
solana_client = Client(endpoint)
for address in all_addresses:
print('address:', address)
#result = solana_client.get_confirmed_signature_for_address2(address, limit=1)
result = solana_client.get_signatures_for_address(address)#, before='89Tv9s2uMGaoxB8ZF1LV9nGa72GQ9RbkeyCDvfPviWesZ6ajZBFeHsTPfgwjGEnH7mpZa7jQBXAqjAfMrPirHt2')
if 'result' in result:
print('len:', len(result['result']))
# I use `[:5]` to display only first 5 values
for number, item in enumerate(result['result'][:5], 1):
print(number, 'signature:', item['signature'])
# check if there is `4SNQ4h1vL9GkmSnojQsf8SZyFvQsaq62RCgops2UXFYag1Jc4MoWrjTg2ELwMqM1tQbn9qUcNc4tqX19EGHBqC5u`
for number, item in enumerate(result['result'], 1):
if item['signature'].startswith('4SN'):
print('found at', number, '>>>', item['signature'])
else:
# error message
print(result)
print('---')
#solana_client.get_account_info(address)
結果：

順便提一句：
因為它只獲得 1000 個值，所以此時您可能看不到4SNQ...~1200 位置處的值，但是如果您使用before=
get_signatures_for_address(address, before='89Tv9s2uMGaoxB8ZF1LV9nGa72GQ9RbkeyCDvfPviWesZ6ajZBFeHsTPfgwjGEnH7mpZa7jQBXAqjAfMrPirHt2')
那么它應該在~970的位置
順便提一句：
在索拉納瀏覽器你有大的按鈕來更改Mainnet到Devnet，當你使用Devnet然后
2AQdpHJ2JpcEgPiATUXjQxA8QmafFegfQwSLWSprPicm也給出了0項。
在同索拉納海灘。還有一個很大的按鈕來更改Mainnet到Devnet，當你使用Devnet然后
2AQdpHJ2JpcEgPiATUXjQxA8QmafFegfQwSLWSprPicm給出了0項。

有趣的是，今天早上我正在研究這個完全相同的問題..就像 furas 指出的那樣，它是端點，需要使用主網端點：
https://api.mainnet-beta.solana.com
我發現即使檔案說你需要輸入 base-58 地址也有點令人困惑，我和你一樣試過它給了我同樣的錯誤，結果我只需要直接復制粘貼我的地址
