PHP如何使用比特币Coinbase钱包库开发应用

摘要：比特币开发教程，本课程面向初学者，内容即涵盖比特币的核心概念，例如区块链存储去中心化共识机制密钥与脚本交易与等，同时也详细讲解如何在代码中集成比特币支持功能，例如创建地址管理钱包构造裸交易等，是工程师不可多得的比特币开发学习课程。

这是Coinbase Wallet API v2的官方客户端库。我们提供直观，稳定的界面，将Coinbase Wallet集成到的PHP项目中。

重要提示：由于此库是针对较新的API v2的，因此需要v2权限（即wallet:accounts:read）。如果你仍在使用v1，请使用此库的旧版本。

使用Composer安装库。如果你不熟悉Composer或依赖管理器，请阅读Composer文档。

"require": {
    "coinbase/coinbase": "~2.0"
}

使用API​​密钥和密钥访问你自己的Coinbase帐户。

use CoinbaseWalletClient;
use CoinbaseWalletConfiguration;

$configuration = Configuration::apiKey($apiKey, $apiSecret);
$client = Client::create($configuration);

使用OAuth2身份验证访问你自己以外的用户帐户。此库不处理握手过程，并假定你在初始化时具有访问token。你可以使用OAuth2客户端（例如league/oauth2-client）处理握手过程。

use CoinbaseWalletClient;
use CoinbaseWalletConfiguration;

// with a refresh token
$configuration = Configuration::oauth($accessToken, $refreshToken);

// without a refresh token
$configuration = Configuration::oauth($accessToken);

$client = Client::create($configuration);

发送资金端点在某些情况下需要2FA令牌（在此处阅读更多内容）。如果需要，则抛出特定异常。

use CoinbaseWalletEnumParam;
use CoinbaseWalletExceptionTwoFactorRequiredException;
use CoinbaseWalletResourceTransaction;

$transaction = Transaction::send([
    "toEmail" => "test@test.com",
    "bitcoinAmount" => 1
]);

$account = $client->getPrimaryAccount();
try {
    $client->createAccountTransaction($account, $transaction);
} catch (TwoFactorRequiredException $e) {
    // show 2FA dialog to user and collect 2FA token

    // retry call with token
    $client->createAccountTransaction($account, $transaction, [
        Param::TWO_FACTOR_TOKEN => "123456",
    ]);
}

几个端点是分页的。默认情况下，库只会获取给定请求的第一页数据。你可以轻松加载不仅仅是第一页结果。

$transactions = $client->getAccountTransactions($account);
while ($transactions->hasNextPage()) {
    $client->loadNextTransactions($transactions);
}

你还可以使用fetch_all参数让库发出加载完整集合的所有必要请求。

use CoinbaseWalletEnumParam;

$transactions = $client->getAccountTransactions($account, [
    Param::FETCH_ALL => true,
]);

注意警告是明智的。如果配置了一个标准PSR-3记录器，库将记录所有警告。

use CoinbaseWalletClient;
use CoinbaseWalletConfiguration;

$configuration = Configuration::apiKey($apiKey, $apiSecret);
$configuration->setLogger($logger);
$client = Client::create($configuration);

在某些情况下，API将返回资源引用来代替扩展的资源对象。可以通过刷新来扩展这些引用。

$deposit = $this->client->getAccountDeposit($account, $depositId);
$transaction = $deposit->getTransaction();
if (!$transaction->isExpanded()) {
    $this->client->refreshTransaction($transaction);
}

你还可以使用expand参数请求API在初始请求中返回扩展资源。

use CoinbaseWalletEnumParam;

$deposit = $this->client->getAccountDeposit($account, $depositId, [
    Param::EXPAND = ["transaction"],
]);

创建新资源时可以使用资源引用，从而避免从API请求资源的开销。

use CoinbaseWalletResourceDeposit;
use CoinbaseWalletResourcePaymentMethod;

$deposit = new Deposit([
    "paymentMethod" => PaymentMethod::reference($paymentMethodId)
]);

// or use the convenience method
$deposit = new Deposit([
    "paymentMethodId" => $paymentMethodId
]);

有多种方法可以访问原始响应数据。首先，每个资源对象都有一个getRawData()方法，你可以使用该方法访问未映射到对象属性的任何字段。

$data = $deposit->getRawData();

来自最后一个HTTP响应的原始数据也可在客户端对象上使用。

$data = $client->decodeLastResponse();

该库包括对资源对象上的活动记录方法的支持。你必须在引导应用程序时启用此功能。

$client->enableActiveRecord();

启用后，你可以在资源对象上调用活动记录方法。

use CoinbaseWalletEnumParam;

$transactions = $account->getTransactions([
    Param::FETCH_ALL => true,
]);

测试套件使用PHPUnit构建。通过运行phpunit命令运行单元测试套件。

phpunit

还有一组集成测试，它们向API发出实际请求并检查生成的对象。要运行这些测试，必须将phpunit.xml.dist复制到phpunit.xml，为CB_API_KEY和CB_API_SECRET变量提供值，并在运行测试套件时指定integration组。

phpunit --group integration
