从Solana事务数据(Solana/web3.js)中获取程序id/地址

Question

我想确定事务是否与特定的程序id进行了交互"cndyAnrLdpjq1Ssp1z8xxDsB8dxe7u4HL5Nxi2K5WXZ"；(为糖果机程序地址(。

我正在使用@solana/web3.js使用connection.getTransaction(txn.signature(.获取以下(帖子底部(Candy Machine薄荷交易数据

如何确定交易是否与糖果机程序交互？

我试着深入研究transaction.meta.innerInstructions，但我不知道如何将其转换为程序id地址。

[
{
'accounts': '2',
'data': '3Bxs4h24hBtQy9rw',
'programIdIndex': '8'
},{
'accounts': '2',
'data': '9krTDU2LzCSUJuVZ',
'programIdIndex': '8'
},{
'accounts': '2',
'data': 'SYXsBSQy3GeifSEQSGvTbrPNposbSAiSoh1YA85wcvGKSnYg',
'programIdIndex': '8'
},
...etc.
]

注意：我意识到我可以在"；logMessages"；字符串，但这有点作弊，我正在努力学习这一切是如何工作的

事务对象被组织为包含它在tx.transaction.message.accountKeys中与之交互的所有帐户(程序是帐户(的列表

对于tx.meta.innerInstructions中的任何指令，您都可以找到一个programIdIndex(tx.meta.innerInstructions.instructions[0].programIdIndex(，它指的是该指令与交互的程序的accounts数组中的索引

这样你就可以找到特定事务的programId，比如

let accs = tx.transaction.message.accountKeys; // get all accs of all ixs
for (let inner_ixs of tx.meta.innerInstructions) {
let first_ix = inner_ixs.instructions[0] // ix of interest 
let program_id = accs[first_ix.programIdIndex].toString(); 

if (program_id != CANDY_PROGRAM_ID) { continue } 
// ...
