如何将标头从请求传递到集成响应？

Question

对 API 网关的请求将包含某些标头，例如X-header，也必须在响应中返回。因此，这些标头必须从请求传递到集成（在本例中为 SQS 队列）返回响应（集成响应）。

此刻，头部从请求传递到集成；但这不能在集成响应中访问（至少据我所知）。

地形代码：

resource "aws_api_gateway_integration" "integration" {
rest_api_id = gateway.id
resource_id = aws_api_gateway_resource.resource.id
http_method = aws_api_gateway_method.method.http_method
type = "AWS"
integration_http_method = "POST"
uri = "arn:aws:apigateway:XXXX:sqs:path/XXXXX/${var.queue_name}"
credentials = aws_iam_role.iam_role_for_sqs.arn
passthrough_behavior = "NEVER"
request_parameters = {
"integration.request.header.Content-Type" = "'application/x-www-form-urlencoded'",
"integration.request.header.X-header" = "method.request.header.X-header" ,
}
}




  resource "aws_api_gateway_integration_response" "response" {
  rest_api_id = var.gateway.id
  resource_id = aws_api_gateway_resource.resource.id
  http_method = aws_api_gateway_method.method.http_method
  status_code = aws_api_gateway_method_response.response.status_code
  response_parameters = {
        "method.response.header.X-header" = "context.responseOverride.header.X-header", //how to access the header?
  }
}

resource "aws_api_gateway_method_response" "response" {
  rest_api_id = var.gateway.id
  resource_id = aws_api_gateway_resource.resource.id
  http_method = aws_api_gateway_method.method.http_method
  status_code = 200
  response_parameters = { 
        "method.response.header.X-header" = true,
       }
  response_models = {
    "application/json" = "Empty"
  }
}

我可以在文档中找到有关 requestOverride 和 responseOverride 的内容，但无法在集成阶段设置 requestOverride。

如何访问在集成阶段传递给集成响应的请求参数？

省略了部分代码。重要的部分是如何访问集成响应中的标头。

解决了： 覆盖响应模板中的标头将允许您通过 input.params() 访问标头

response_templates = {
    "application/json" = <<EOT
    #set($context.responseOverride.header.X-header = "$util.escapeJavaScript($input.params().header.get('X-header'))"))
        {            
        }
    EOT
}
