需求

[](#需求)

- PHP `^8.3`

安裝
--

[](#安裝)

```
composer require carllee1983/ecpay-einvoice-b2c
```

快速開始
----

[](#快速開始)

```
use CarlLee\EcPayB2C\EcPayClient;
use CarlLee\EcPayB2C\Operations\Invoice;
use CarlLee\EcPayB2C\DTO\InvoiceItemDto;

$server = 'https://einvoice-stage.ecpay.com.tw';
$merchantId = '2000132';
$hashKey = 'ejCk326UnaZWKisg';
$hashIV = 'q9jcZX8Ib9LM8wYk';

$client = new EcPayClient($server, $hashKey, $hashIV);

$invoice = new Invoice($merchantId, $hashKey, $hashIV);
$invoice->setRelateNumber('YEP' . date('YmdHis'))
    ->setCustomerEmail('demo@example.com')
    ->setItems([
        InvoiceItemDto::fromArray(['name' => '商品範例', 'quantity' => 1, 'unit' => '個', 'price' => 100]),
    ])
    ->setSalesAmount(100);

$response = $client->send($invoice);
$data = $response->getData();
```

命令契約（重要）
--------

[](#命令契約重要)

- `EcPayClient::send()` 只接受 `CarlLee\EcPayB2C\Contracts\SendableCommandInterface`（通常直接繼承 `CarlLee\EcPayB2C\Content` 即可）。
- 舊的 `CarlLee\EcPayB2C\InvoiceInterface` 已標記 deprecated（相容層）。
- 若需自行檢視「實際送出的加密內容」，建議呼叫 `Content::getTransportBody()`（`getContent()` 為相容名稱）。
