v2 API use algo get txId and get transaction by txid

[crossle]

Have any method get the txId use /v2/blocks/xx , i dont wanna deploy the indexer node, only have the algo node.

[crossle]

Or calculate the txId base on /v2/blocks/xx txn ？

[crossle]

Any update?

You should be able to get the txid from the SignedTransactionInBlock, after setting the appropriate values on the Transaction object (genesis hash/gensis id) then passing it to crypto.GetTxID

something like this:

t.Txn.GenesisID = b.GenesisID
t.Txn.GenesisHash = b.GenesisHash
txid := crypto.GetTxID(t.Txn)

[crossle]

But maybe the transaction not have GenesisID, because when make a transaction don't need fill the GenesisID

GetTxID works correctly.
Valid transactions always have the genesis id.
The various helpers that assemble the transaction headers set it for you from the passed in SuggestedParams struct.
