java - 使用Java API TransmissionWithRecipientArray对象，如何设置像键值数组这样的元素(Sparkpost)

Question

我正在根据模板使用 Java API TransmissionWithRecipientArray 对象发送电子邮件。我在替换数据方面遇到一些问题。我已在模板编辑器中测试了此数据，但我不知道如何使用 TransmissionWithRecipientArray 引入替换数据。

这是一个示例:

(...), "offers": [
     {
       "description": "dddddddddddddddddd.",
       "discount": "ddddddd",
       "image": "ddddddddddddddddddddd",
       "image_announcer": "dddddddddddddddddddddddddddd",
       "alt_title": "dddddddddddddddddddddd",
       "tracking": "dhsdjkhsdjksdh",
       "name": "sdhsdohdsiosd",
       "id": "8480515",
       "announcer_paid": "0",
       "announcer_image": "test",
       "announcer_alt_title": "wdiohdiowdhiowd"
     },
      {
       "description": "dddddddddddddddddd.",
       "discount": "ddddddd",
       "image": "ddddddddddddddddddddd",
       "image_announcer": "dddddddddddddddddddddddddddd",
       "alt_title": "dddddddddddddddddddddd",
       "tracking": "dhsdjkhsdjksdh",
       "name": "sdhsdohdsiosd",
       "id": "8480515",
       "announcer_paid": "0",
       "announcer_image": "test",
       "announcer_alt_title": "wdiohdiowdhiowd"
     }, (...)

换句话说，问题是:我们应该在 setSubstitutionData() 方法中引入什么来将此输入作为替换数据？我们已使用模板编辑器验证了替换数据。

transmission.setSubstitutionData(allSubstitutionData.asJava)

强制 HTML:

 {{offers[1].description}}

Answer 1

每documentation ，在模板中循环数组的方式是:

{{ if offers }}
<ul>
  {{ each offer }}
  <li>Offer title is <b>{{ loop_var.name }}</b></li>
  {{ end }}
</ul>
{{ end }}

您需要使用变量loop_var，如果您在数组中传递一个对象，则loop_var将是您的对象的根。因此，如果您想打印 discount 字段，则需要编写 loop_var.discount。
