我正在为具有 /user/{uid}/cart 等路径的终端节点开发 AWS Cloud Formation 模板。我需要创建与 HTTP 主机的集成。我一直在尝试将 {uid} 映射到集成请求 URL 路径参数，如下所示:
"x-amazon-apigateway-integration": {
"uri": "http://${stageVariables.httpHost}/user/{uid}/cart",
"contentHandling": "CONVERT_TO_TEXT",
"timeoutInMillis": 29000,
"connectionType": "INTERNET",
"httpMethod": "PUT",
"passthroughBehavior": "WHEN_NO_MATCH",
"type": "HTTP_PROXY",
"requestParameters": {
"integration.request.path.uid" : "method.request.path.uid"
}...
我不断收到此错误，但我不确定我做错了什么。
Errors found during import: Unable to put integration on 'PUT' for resource at path '/user/{uid}/cart': Invalid mapping expression specified: Validation Result: warnings : [], errors : [Invalid mapping expression parameter specified: method.request.path.uid]
这是完整的模板

感谢您的帮助!
最佳答案
问题出在参数的位置。这些需要位于 PUT 下，而不是位于 path 下。
"paths": {
"/user/{uid}/cart": {
"put": {
"tags": [
"users",
"cart"
],
"parameters": [
{
"name": "uid",
"in": "path",
"description": "user id",
"required": true,
"type": "string",
"format": "uuid"
}
],...
