እንደ Ademola እንደገለጸው የግብይትህን ዳታ የ instruction discriminator ማቅረብ አለብህ።
ማድረግ የምትችለው instruction discriminator ን ማምጣት ነው ከዚያም በመጀመሪያዎቹ 8 bytes ውስጥ ከዳታህ ጋር አያዝው።
በ Rust Instruction Discriminator ማምጣት
pub fn sighash(namespace: &str, name: &str) -> [u8; 8] {
let preimage = format!("{}:{}", namespace, name);
let mut sighash = [0u8; 8];
sighash.copy_from_slice(
&anchor_client::anchor_lang::solana_program::hash::hash(preimage.as_bytes()).to_bytes()
[..8],
);
sighash
}
println!("{:?}", sighash("global", "initialize"));
በ typescript Discriminator Instruction ማምጣት
function sighash(nameSpace: string, ixName: string): Buffer {
let name = snakeCase(ixName);
let preimage = `${nameSpace}:${name}`;
return Buffer.from(sha256.digest(preimage)).slice(0, 8);
}
namespace global መሆን አለበት
በ Typescript ውስጥ ምሳሌ እነሆ
// Craft the InstructionBuffer
const ixBuffer = sighash('global','initialize');
const instructionBuffer = Buffer.concat([
ixBuffer, // namespace+method_name
OtherBuffer, // Other Data that you want to pass to the instruction.
])
// Craft the Instruction
const transactionInstruction = new TransactionInstruction({
programId: programAddress,
data: instructionBuffer,
keys : [
...
]
})
