我想实现的目标是编写一个SAM模板，以获取由Api Gateway事件触发的Lambda函数。我希望有多个API阶段（例如“dev”，“testing”，“prod”），我希望每个阶段都映射到具有相同名称的Lambda别名。我更喜欢不在每次部署时生成新的lambda版本，并手动设置要由每个lambda别名使用的lambda版本。当然，“dev”别名应指向$LATEST代码版本。
我修改了经典的“hello_world”模板如下。现在，当第一次部署（比如到“dev”）时，一切似乎按预期工作。但是，如果我尝试部署到“测试”阶段，则此新阶段上的API会响应，而“dev”阶段上的API会停止响应。
我漏掉了什么？
