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

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
  }
}

With this script, I am trying to add a URL query parameter named tableid with caching enabled. But I can see no documentation referring to enabling the caching.

CodePudding user response：

To do so, this can be done using cache_key_parameters and cache_namespace below the aws_api_gateway_integration as follows:

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" 
}
