轮播中的自适应卡限制，即 Azure Bot Framework SDKV4

【问题标题】：Adaptive Card limit in Carousel i.e. Azure Bot Framework SDKV4轮播中的自适应卡限制，即 Azure Bot Framework SDKV4
【发布时间】：2020-07-24 22:43:37
【问题描述】：

我面临一个基本问题。我想在轮播卡中显示搜索。我使用自适应卡来设计所需的显示，并使用 c# 代码将自适应卡作为附件添加到轮播卡。如果我的轮播卡包含少于 60 个附件作为自适应卡，则 azure bot 可以正常工作，否则会开始中断。

另一方面，如果我使用带有 150 个附件的模拟器作为轮播卡中的自适应卡。它的工作正常。 我检查了多次，数据没有错误。 您能否建议，是否有任何限制或大小或可接受的字符来显示数据。

附加错误屏幕截图供参考：- 网络聊天测试时出错。

堆栈跟踪错误：

【解决方案1】：

Web Chat 是 Direct Line 客户端。来自Direct Line documentation：

在序列化为 JSON 并加密后，活动的总大小不得超过 256K 个字符。因此，建议将活动保持在 150K 以下。如果需要更多数据，请考虑将活动分成多个和/或考虑使用附件。

当它说“考虑使用附件”时，它表示与活动分开并通过 URL 引用的附件。您使用的卡片附件是活动的一部分，它们的 JSON 会影响活动的文件大小。当然，仍然建议将您的活动分成多个活动，以便每个活动更小。

模拟器不使用 Direct Line，因此不受其限制。
