Come decodificare una transazione grezza?

Taquitopuò analizzarei byte contraffatti utilizzandoilmetodo parse()nelpacchetto @taquito/local-forging.

I TypeDoc sono qui . Puoi vederegli unittest qui .

Implementazioneper decodificare unatransazionefirmata:

 const { localForger } = require('@taquito/local-forging');

const sbytes = '008f1d96e2783258ff663f03dacfe946c026a5d194c73d1987b3da73fadea7d46c008cb5baedee4dc3ec261dfcf57a9600bb0a8e26c0f00bdd85a0018452ac02e0a712000153957451d3cc83a71e26b65ea2391a1b16713d2d009595facf847a72b4c3fe231c0e4185e68e9b2875aa3c639382c86bcf0af23699f47fe66a6550ade936a5b59d5919ad20703885750314e0c368b277de39e7d10a';

async function decode() {
    const unsignedPart = sbytes.substring(0, sbytes.length - 128); // Removing last 128 characters as that is the signature
    const decoded = await localForger.parse(unsignedPart);
    console.log(decoded);
}

decode(); 
 

Taquito can parse forged bytes using the parse() method in the @taquito/local-forging package.

TypeDocs are here. You can see the unit tests here.

Implementation to decode a signed transaction:

const { localForger } = require('@taquito/local-forging');

const sbytes = '008f1d96e2783258ff663f03dacfe946c026a5d194c73d1987b3da73fadea7d46c008cb5baedee4dc3ec261dfcf57a9600bb0a8e26c0f00bdd85a0018452ac02e0a712000153957451d3cc83a71e26b65ea2391a1b16713d2d009595facf847a72b4c3fe231c0e4185e68e9b2875aa3c639382c86bcf0af23699f47fe66a6550ade936a5b59d5919ad20703885750314e0c368b277de39e7d10a';

async function decode() {
    const unsignedPart = sbytes.substring(0, sbytes.length - 128); // Removing last 128 characters as that is the signature
    const decoded = await localForger.parse(unsignedPart);
    console.log(decoded);
}

decode(); 

Puoi usareilbinario tezos-codecper decodificare questo:

 tezos-codec decode 006-PsCARTHA.operation from 008f1d96e2783258ff663f03dacfe946c026a5d194c73d1987b3da73fadea7d46c008cb5baedee4dc3ec261dfcf57a9600bb0a8e26c0f00bdd85a0018452ac02e0a712000153957451d3cc83a71e26b65ea2391a1b16713d2d009595facf847a72b4c3fe231c0e4185e68e9b2875aa3c639382c86bcf0af23699f47fe66a6550ade936a5b59d5919ad20703885750314e0c368b277de39e7d10a

You can use the tezos-codec binary to decode this:

tezos-codec decode 006-PsCARTHA.operation from 008f1d96e2783258ff663f03dacfe946c026a5d194c73d1987b3da73fadea7d46c008cb5baedee4dc3ec261dfcf57a9600bb0a8e26c0f00bdd85a0018452ac02e0a712000153957451d3cc83a71e26b65ea2391a1b16713d2d009595facf847a72b4c3fe231c0e4185e68e9b2875aa3c639382c86bcf0af23699f47fe66a6550ade936a5b59d5919ad20703885750314e0c368b277de39e7d10a

Puoi utilizzare l'endpoint RPC: /chains/main/blocks/head/helpers/parse/operationsperfarlo.

Esempio:

 await axios.post(
        `${nodeURL}/chains/main/blocks/head/helpers/parse/operations`,
            parseOperationBytesData,
            {
                headers: {
                    'Content-Type': 'application/json'
                }
            }
        )
 

You can use the RPC endpoint: /chains/main/blocks/head/helpers/parse/operations to do that.

Example:

await axios.post(
        `${nodeURL}/chains/main/blocks/head/helpers/parse/operations`,
            parseOperationBytesData,
            {
                headers: {
                    'Content-Type': 'application/json'
                }
