使用 terraform 在 aws api 网关中为 url 查询参数启用缓存

Enable caching for url query parameters in aws api gateway with terraform

resource "aws_api_gateway_method" "MyDemoMethod" {
  rest_api_id   = aws_api_gateway_rest_api.example.id
  resource_id   = aws_api_gateway_resource.MyDemoResource.id
  http_method   = "ANY"
  authorization = "NONE"

  request_parameters = {
    "method.request.path.proxy" = true
    "method.request.querystring.tableid" = true
  }
}

使用此脚本,我试图添加一个名为 tableid 的 URL 查询参数并启用缓存。但是我看不到任何关于启用缓存的文档。

为此,可以使用 aws_api_gateway_integration 下方的 cache_key_parameterscache_namespace 来完成,如下所示:

resource "aws_api_gateway_method" "MyDemoMethod" {
  rest_api_id   = aws_api_gateway_rest_api.example.id
  resource_id   = aws_api_gateway_resource.MyDemoResource.id
  http_method   = "ANY"
  authorization = "NONE"

  request_parameters = {
    "method.request.path.proxy" = true
    "method.request.querystring.tableid" = true
  }
}


resource "aws_api_gateway_integration" "MyDemoIntegration" {
  rest_api_id          = aws_api_gateway_rest_api.MyDemoAPI.id
  resource_id          = aws_api_gateway_resource.MyDemoResource.id
  http_method          = aws_api_gateway_method.MyDemoMethod.http_method
  type                 = "MOCK"
  cache_key_parameters = ["method.request.querystring.tableid"]
  cache_namespace      = "mycache" 
}
