试图让aws-sam-local提供我的API

Question

我有一个简单的项目。基本设置就像这样......

project
 |- etc
 |   |- sam.yaml
 |   \- swagger.yaml
 |- src
 |   |- client
 |   |   \- Client files (VUE frontend)
 |   \- backend
 |       |- index.js
 |       \- package.json
 \- gulpfile.js

我运行gulp，最后得到一个build文件夹。它看起来像这样......

build
 |- client
 |   |- index.html
 |   \- More static client files
 |- backend
 |   |- index.js
 |   |- package.json
 |   \_ node_modules
 |       \- Lots of stuff
 \- backend.zip

构建效果很好。我希望在本地运行它，而不是每次进行更改时将ZIP上传到lambda，将客户端目录上传到S3。

为此，我正在运行aws-sam-local。是的，我已安装并运行docker。从项目文件夹我运行...

sam local start-api -t etc/sam.yaml -s ../build/client/

现在我可以访问我的浏览器并访问http://localhost:3000/查看内容。正如预期的那样，我的静态文件（index.html）加载得很好。但是当我尝试访问API路由http://localhost:3000/test时，我得到了404。

我的sam.yaml
