Qaysi PHP versiyasi kerak?

PHP 7.4 yoki undan yangroq. iexbase/tron-api paketi GMP va bcmath kengaytmalarini talab qiladi.

Nima uchun imzolash uchun Node.js yordamchisi kerak?

iexbase/tron-api PHP kutubxonasi tronWeb.trx.signMessageV2() ni ochib bermaydi, bu TronEnergy API talab qiladi. Node.js yordamchisi imzolashni va PHP uchun imzoni chiqariyadigan kichik oqali.

PHP Integratsiyasi | TronEnergy Docs

Barcha PHP integratsiyasi qo'llab iexbase/tron-api kutubxonasini qo'llab. Har bir bosqich sizning loyihangizga nusxa ko'chirib qo'yishingiz mumkin bo'lgan mustaqil kod blokidir. Har qanday PHP freymvorki yoki oddiy PHP bilan ishlaydi.

Oldindan tayyorgarlik: PHP 7.4+, Composer, ext-gmp va ext-bcmath yoqilgan, moliyalashtirilgan Tron hamyoni.

PHP-da imzolash haqida: TronEnergy API hamyon imzosi talab qiladi tronWeb.trx.signMessageV2() yordamida. iexbase/tron-api kutubxonasi ushbu aniq imzolash dastasini ko'rsatmaydi, shuning uchun ushbu qo'llanma imzolash bosqichi uchun kichik Node.js yordamchisini qo'llanadi. Boshqa hamma (TRX yuborish, API chaqirish, USDT yuborish) PHP-da qoladi. Agar sizda to'g'ri signMessageV2 imzosi hosil qiladigan sof PHP imzolash yechimi bo'lsa, boshqa qadamni o'zgartirmasdan yordamchini almashtira olasiz.

Oqim

API kaliti yo'q. Ro'yxatga olish yo'q. Sizning kod chain-da TronEnergy to'lov manzili uchun TRX yuboradi, egalik bo'yicha isbotlovchi xabar imzolaydi, keyin ijara qilishni talab qiladi. Energiya taxminan 3 soniyada keladi. Keyin sizning kod ijara qilingan energiyadan foydalanib USDT yuboradi.

TRX Yuboring

Zanjirda to'lov manzilga 4 yoki undan ko'p TRX yuboring (min 4, max 1000).

Imzolang

Siz yuboruvchi ekanligingizni isbotlash uchun tx_hash:delegate_to imzolang.

Talab Qiling

tx xesh va imzo bilan /delegate-ga POST qiling. Energiya ~3s ichida keladi.

Narx chiziqli: har bir TRX uchun 16,250 energiya. Minimal buyurtma 4 TRX (65,000 energiya — bitta standart USDT o'tkazmasi), maksimal 1,000 TRX (16.25M energiya). Siz yuborgan miqdor aynan qancha energiya delegatsiya qilinishini aniqlaydi — hech qanday darajalar, hech qanday paketlar yo'q. Bitta standart o'tkazmasi uchun $trxAmount = 4 ishlatish. Yangi hamyon o'tkazmasi uchun 8 ishlatish. Guruh ishlar uchun ko'proq ishlatish. Quyidagi kod $trxAmount o'zgaruvchisini ishlatadi, shuning uchun siz uni bitta joyda o'zgartirishingiz mumkin.

Qadam-Qadamla

1. O'rnatish

composer

composer require iexbase/tron-api

2. Sozlash

setup.php
require_once 'vendor/autoload.php';

use IEXBase\TronAPI\Tron;

$tron = new Tron();
$tron->setPrivateKey('YOUR_PRIVATE_KEY');
$tron->setAddress('YOUR_WALLET_ADDRESS');

$api  = 'https://api.tronnrg.com';
$addr = 'TFqUiCu1JwLHHnBNeaaVKH7Csm4aA3YhZx'; // API payment address
$usdt = 'TR7NHqjeKQxGTCi8q8ZY4pL8otSzgjLj6t'; // USDT contract

Hech qachon credentials ni kodga joylashtirmang. Shaxsiy kalitingizni muhit o'zgaruvchilari yoki maxfiy menejeridan yuklang. Hech qachon maxfiylarni git-ga commit qilmang.

4. TRX Yuborish

TRX yuborish
// Send TRX to the API payment address — pricing is linear.
// 16,250 energy per TRX. Min 4 TRX, max 1,000 TRX.
//   $trxAmount = 4    → 65,000 energy   (standard USDT transfer)
//   $trxAmount = 8    → 130,000 energy  (new wallet transfer)
//   $trxAmount = 40   → 650,000 energy  (10 standard transfers)
//   $trxAmount = 1000 → 16,250,000 energy (max)

$trxAmount = 4;

$payment = $tron->sendTrx($addr, $trxAmount);

if (!isset($payment['result']) || !$payment['result']) {
    throw new Exception('TRX transfer failed');
}

$txHash = $payment['txid'];
echo "Payment sent: ${txHash}\n";

5. Xabarni Imzolash

API TRX yuborgan bir xil hamyon delegatsiyani so'rayotganini isbotlaydigan imzoни talab qiladi. Biz buni kichik Node.js yordamchisi bilan qilamiz. Uni PHP fayla yoniga sign.js sifatida saqlang:

sign.js
// Usage: node sign.js <tx_hash> <delegate_to>
// Outputs the signature to stdout. Reads private key from TRON_PRIVATE_KEY env var.
const { TronWeb } = require('tronweb');

const [, , txHash, delegateTo] = process.argv;
const tronWeb = new TronWeb({
  fullHost: 'https://api.trongrid.io',
  privateKey: process.env.TRON_PRIVATE_KEY,
});

tronWeb.trx.signMessageV2(`${txHash}:${delegateTo}`)
  .then(sig => process.stdout.write(sig))
  .catch(e => { console.error(e.message); process.exit(1); });

TronWeb ni bir xil papkaga o'rnating: npm install tronweb. Keyin PHP dan uni chaqiring:

PHP dan imzolash
// Both the sender (in $tron) and the signer must be the SAME wallet.
// Make sure TRON_PRIVATE_KEY in your environment matches the wallet that sent the TRX.
$delegateTo = 'TWalletThatNeedsEnergy';

$signature = trim(shell_exec(
    sprintf('node sign.js %s %s',
        escapeshellarg($txHash),
        escapeshellarg($delegateTo)
    )
));

if (!$signature) {
    throw new Exception('Signing failed. Check that node and tronweb are installed and TRON_PRIVATE_KEY is set.');
}

echo "Signed: " . substr($signature, 0, 20) . "...\n";

6. Delegatsiyani Olish

delegatsiyani da'vo qilish
// $txHash, $delegateTo, and $signature are all defined in the previous steps.
$ch = curl_init("${api}/delegate");
curl_setopt_array($ch, [
    CURLOPT_POST           => true,
    CURLOPT_RETURNTRANSFER => true,
    CURLOPT_HTTPHEADER     => ['Content-Type: application/json'],
    CURLOPT_POSTFIELDS     => json_encode([
        'tx_hash'     => $txHash,
        'delegate_to' => $delegateTo,
        'signature'   => $signature,
    ]),
]);

$result = json_decode(curl_exec($ch), true);
curl_close($ch);

echo "Energy: " . $result['energy'] . "\n";
echo "Ref: " . $result['ref'] . "\n";

7. USDT Yuborish

USDT yuborish
// Energy is now delegated. Send USDT.
$contract = $tron->contract($usdt);
$transfer = $contract->transfer($delegateTo, 10 * pow(10, 6));

echo "USDT sent: " . $transfer . "\n";

Xato Boshqarish

Claim chaqiruvini kichik qayta harakat yordamchisiga o'ring. Eng keng tarqalgan xato — payment_verification_failed txn hali zanjirada indekslanganda — bir necha soniya kuting va yana bir marta qayta harakat qiling.

xato boshqaruvi
function claimDelegation($api, $txHash, $delegateTo, $signature, $retries = 3) {
    for ($i = 0; $i < $retries; $i++) {
        $ch = curl_init("${api}/delegate");
        curl_setopt_array($ch, [
            CURLOPT_POST           => true,
            CURLOPT_RETURNTRANSFER => true,
            CURLOPT_HTTPHEADER     => ['Content-Type: application/json'],
            CURLOPT_POSTFIELDS     => json_encode([
                'tx_hash'     => $txHash,
                'delegate_to' => $delegateTo,
                'signature'   => $signature,
            ]),
        ]);

        $result = json_decode(curl_exec($ch), true);
        curl_close($ch);

        if (!isset($result['error'])) {
            return $result; // Success
        }

        switch ($result['error']) {
            case 'payment_verification_failed':
                // Most common: tx not yet indexed. Wait and retry.
                sleep(3);
                continue 2;

            case 'hash_already_used':
                throw new Exception('This tx hash has already been claimed');

            case 'signature_mismatch':
                throw new Exception('Signer does not match payment sender. Sign with the same wallet that sent TRX.');

            case 'delegation_failed':
                // Refund queued automatically if payment was verified
                throw new Exception('Delegation failed: ' . $result['message']);

            default:
                throw new Exception($result['message'] ?? 'Unknown error');
        }
    }

    throw new Exception('Transaction not found after retries');
}
