如何通过apigatewayv2-controller配置覆盖HTTP Host请求头？

要通过apigatewayv2-controller的Integration配置覆盖Host请求头为my.local.host，requestParameters的正确格式如下：

核心配置片段 #

requestParameters:
  integration.request.header.Host: "'my.local.host'"

完整的Integration清单 #

apiVersion: apigatewayv2.services.k8s.aws/v1alpha1
kind: Integration
metadata:
  name: integration-my
  namespace: rental-connect
spec:
  apiRef:
    from:
      name: adopt-api-gateway-my
  connectionID: id
  integrationType: HTTP_PROXY
  connectionType: VPC_LINK
  integrationURI: arn:aws:elasticloadbalancing:eu-central-1:...
  integrationMethod: ANY
  payloadFormatVersion: "1.0"
  requestParameters:
    integration.request.header.Host: "'my.local.host'"

关键说明 #

• 键名integration.request.header.Host是AWS HTTP API的标准参数格式，用于指定要修改的集成请求头
• 值部分需要用单引号包裹目标Host值，确保YAML正确解析固定字符串，API网关会将转发到后端的Host头固定设置为my.local.host
