更新卡券类和卡券对象

及时更新卡券是与客户互动并打造良好体验的重要方法。

有两个资源可以更新：TransitClass 和 TransitObject。

最佳做法

以下列表包含在更新公交卡类和对象时要考虑的实用信息：

  • 如果要更新整个类或对象，请发送 update 请求。如果您要更新某个类或对象中的少量字段，请发送 patch 请求。
  • 当您发出 update 请求时，整个对象或类都会更新。这意味着请求中未包含的所有字段都将被清除。 在发送 update 请求之前，我们建议您先发送 GET 请求，以确保使用的是最新版本，且您的请求中包含所有预期字段。
  • 在发出 patch 请求时，只有修补后的字段才会更新。在发送 patch 请求之前，可以考虑选择性地发送 GET 请求，将您的更改与最新版本进行比较。
  • 发出更新数组的 patch 请求时，原始数组会替换为请求正文中包含的数组。您无法单独修改数组中的元素。
  • 在某些情况下，您可能不知道何时会发生变化或何时触发更新。考虑定期为所有类和对象安排 update 或 patch 请求。

更新卡券类

使用 Google 电子钱包商家控制台

卡券类（而非对象）可以直接在 Google Pay & Wallet Console 中进行修改。

  1. 前往控制台
  2. 选择 Google Wallet API
  3. 选择要修改的课程
  4. 选择修改
  5. 更新类属性
  6. 选择保存。

保存更改后，该类会自动为所有公交持有者更新。

使用 Google Wallet API

更新 TransitClass 会影响所有已使用此类预配公交卡的用户。例如，要更新公交卡的徽标，您可以在以下任一端点向 Google Wallet API 提交 update 或 patch 请求。resourceId 的值将是类 ID (ISSUER_ID.CLASS_SUFFIX)。

# Update
PUT https://walletobjects.googleapis.com/walletobjects/v1/transitclass/{resourceId}

# Patch
PATCH https://walletobjects.googleapis.com/walletobjects/v1/transitclass/{resourceId}

更新单个 TransitObject 只会影响已预配该特定对象的用户。您应该定期更新各个公交卡，以反映影响客户的变化并保持与客户的互动。resourceId 的值将是对象 ID (ISSUER_ID.OBJECT_SUFFIX)。
