【问题描述】：

我有一个 SAM 模板，用于构建与 API 网关集成的 4 个 lambda 函数。

#  integrating lambda with api for loadeo_create_user function
  GetUserProfile:

            Method: put
            RestApiId:
              Ref: ApiGatewayApi

在此之后的下一步是打包和部署代码。

我正在使用aws cloudformation package，因为它类似于sam package，并且我都尝试过。

只要我运行命令，模板文件就会减少。从 100 行到 50 行。当我观察到中间的两个函数被省略时。

不知道这是什么原因。函数的数量有限制吗？还是我遗漏了什么？

【解决方案1】：

两个函数被省略了。

函数被跳过，因为它们有同名 GetUserProfile。因此，当您拥有其中三个时，一个会覆盖另一个。您必须重命名它们：

【讨论】：

但他们是 get_user_profile 和 update_user_profile
@sumanthshetty 我的意思是资源名称，而不是函数名称。在您的原始代码中，SAM 中的资源名称是相同的GetUserProfile。你有三次GetUserProfile。
