PHP SDK 提供了一种强大而灵活的方式，将 Dodo Payments 集成到您的 PHP 应用程序中。它遵循现代 PHP 标准，使用 PSR-4 自动加载，提供广泛的测试覆盖和详细的文档。

​
安装

使用 Composer 安装 SDK： 
composer require "dodopayments/client 5.8.1"
SDK 需要 PHP 8.1.0 或更高版本，并使用 Composer 管理依赖项。

​
快速开始

初始化客户端并创建一个结账会话： 
<?php

use Dodopayments\Client;

$client = new Client(
  bearerToken: getenv('DODO_PAYMENTS_API_KEY') ?: 'My Bearer Token',
  environment: 'test_mode',
);

$checkoutSessionResponse = $client->checkoutSessions->create(
  productCart: [["productID" => "product_id", "quantity" => 1]]
);

var_dump($checkoutSessionResponse->session_id);
安全地使用环境变量存储 API 密钥。切勿将其暴露在代码库中或提交到版本控制系统。

​
核心功能

PSR-4 Compliant

遵循现代 PHP 开发的 PHP 标准建议

Modern PHP

为 PHP 8.1+ 构建，包含类型声明和严格类型

Extensive Testing

提供全面的测试覆盖，确保可靠性和稳定性

Exception Handling

为不同错误场景提供清晰的异常类型

​
值对象

SDK 使用命名参数指定可选参数。您可以使用静态 with 构造函数初始化值对象： 
<?php

use Dodopayments\Customers\AttachExistingCustomer;

// Recommended: Use static 'with' constructor with named parameters
$customer = AttachExistingCustomer::with(customerID: "customer_id");
也可以使用构建器作为可选模式： 
<?php

use Dodopayments\Customers\AttachExistingCustomer;

// Alternative: Use builder pattern
$customer = (new AttachExistingCustomer)->withCustomerID("customer_id");

​
配置

​
重试配置

某些错误默认为自动重试 2 次，并进行短暂的指数退避。以下错误会触发自动重试：
  • 连接错误（网络连接问题）
  • 408 请求超时
  • 409 冲突
  • 429 速率限制
  • 500 以上的内部错误
  • 超时
全局或针对每个请求配置重试行为： 
<?php

use Dodopayments\Client;

// Configure default for all requests (disable retries)
$client = new Client(requestOptions: ['maxRetries' => 0]);

// Or, configure per-request
$result = $client->checkoutSessions->create(
  productCart: [["productID" => "product_id", "quantity" => 1]],
  requestOptions: ['maxRetries' => 5],
);

​
常见操作

​
创建结账会话

生成结账会话： 
$session = $client->checkoutSessions->create(
  productCart: [
    ["productID" => "prod_123", "quantity" => 1]
  ],
  returnUrl: "https://yourdomain.com/return"
);

header('Location: ' . $session->url);

​
管理客户

创建并检索客户信息： 
// Create a customer
$customer = $client->customers->create(
  email: "customer@example.com",
  name: "John Doe",
  metadata: [
    "user_id" => "12345"
  ]
);

// Retrieve customer
$customer = $client->customers->retrieve("cus_123");
echo "Customer: {$customer->name} ({$customer->email})";

​
处理订阅

创建并管理循环订阅： 
// Create a subscription
$subscription = $client->subscriptions->create(
  customerID: "cus_123",
  productID: "prod_456",
  priceID: "price_789"
);

// Cancel subscription
$client->subscriptions->cancel($subscription->id);

​
分页

处理分页列表响应： 
$page = $client->payments->list();

var_dump($page);

// Fetch items from the current page
foreach ($page->getItems() as $item) {
  var_dump($item->brand_id);
}

// Auto-paginate: fetch items from all pages
foreach ($page->pagingEachItem() as $item) {
  var_dump($item->brand_id);
}

​
错误处理

当库无法连接到 API 或收到非成功状态码（4xx 或 5xx）时，会抛出 APIException 的子类： 
<?php

use Dodopayments\Core\Exceptions\APIConnectionException;
use Dodopayments\Core\Exceptions\RateLimitException;
use Dodopayments\Core\Exceptions\APIStatusException;

try {
  $checkoutSessionResponse = $client->checkoutSessions->create(
    productCart: [["productID" => "product_id", "quantity" => 1]]
  );
} catch (APIConnectionException $e) {
  echo "The server could not be reached", PHP_EOL;
  var_dump($e->getPrevious());
} catch (RateLimitException $_) {
  echo "A 429 status code was received; we should back off a bit.", PHP_EOL;
} catch (APIStatusException $e) {
  echo "Another non-200-range status code was received", PHP_EOL;
  echo $e->getMessage();
}

​
错误类型

原因错误类型
HTTP 400BadRequestException
HTTP 401AuthenticationException
HTTP 403PermissionDeniedException
HTTP 404NotFoundException
HTTP 409ConflictException
HTTP 422UnprocessableEntityException
HTTP 429RateLimitException
HTTP >= 500InternalServerException
其他 HTTP 错误APIStatusException
超时APITimeoutException
网络错误APIConnectionException
始终在 try-catch 块中包装 API 调用，以优雅地处理潜在错误并为用户提供有意义的反馈。

​
高级用法

​
未记录的端点

向未记录的端点发送请求： 
<?php

$response = $client->request(
  method: "post",
  path: '/undocumented/endpoint',
  query: ['dog' => 'woof'],
  headers: ['useful-header' => 'interesting-value'],
  body: ['hello' => 'world']
);

​
未记录的参数

向任何端点发送未记录的参数或读取未记录的响应属性： 
<?php

use Dodopayments\RequestOptions;

$checkoutSessionResponse = $client->checkoutSessions->create(
  productCart: [["productID" => "product_id", "quantity" => 1]],
  requestOptions: [
    'extraQueryParams' => ["my_query_parameter" => "value"],
    'extraBodyParams' => ["my_body_parameter" => "value"],
    'extraHeaders' => ["my-header" => "value"],
  ],
);
相同名称的 extra* 参数会覆盖文档中的参数。

​
框架集成

​
Laravel

为 Laravel 应用创建服务： 
<?php

namespace App\Services;

use Dodopayments\Client;

class PaymentService
{
    protected $client;

    public function __construct()
    {
        $this->client = new Client(
            bearerToken: config('services.dodo.api_key')
        );
    }

    public function createCheckout(array $items)
    {
        return $this->client->checkoutSessions->create(
            productCart: $items,
            returnUrl: route('checkout.return')
        );
    }
}
在 config/services.php 中添加配置： 
'dodo' => [
    'api_key' => env('DODO_API_KEY'),
    'environment' => env('DODO_ENVIRONMENT', 'sandbox')
],

​
Symfony

在 Symfony 中创建服务： 
<?php

namespace App\Service;

use Dodopayments\Client;

class DodoPaymentService
{
    private Client $client;

    public function __construct(string $apiKey)
    {
        $this->client = new Client(bearerToken: $apiKey);
    }

    public function createPayment(int $amount, string $currency, string $customerId): object
    {
        return $this->client->payments->create(
            amount: $amount,
            currency: $currency,
            customerID: $customerId
        );
    }
}
在 config/services.yaml 注册： 
services:
  App\Service\DodoPaymentService:
    arguments:
      $apiKey: "%env(DODO_API_KEY)%"
