您可以通过在每个路由的模板中定义CloudWatch Enpoint属性来为每个API网关路由添加唯一的CloudWatch Endpoint。以下是一个示例代码片段，其中每个路由都有不同的CloudWatch Endpoint：

{
  "swagger": "2.0",
  "info": {
    "title": "API Gateway Example",
    "version": "1.0"
  },
  "paths": {
    "/route1": {
      "x-amazon-apigateway-any-method": {
        "parameters": [
          {
            "name": "CloudWatchEndpoint",
            "in": "header",
            "required": true,
            "type": "string",
            "default": "arn:aws:logs:us-east-1:123456789012:log-group:/aws/api-gateway/my-api"
          }
        ],
        "x-amazon-apigateway-integration": {
          "type": "http",
          "httpMethod": "POST",
          "uri": "https://example.com",
          "passthroughBehavior": "when_no_templates",
          "requestParameters": {
            "integration.request.header.CloudWatchEndpoint": "method.request.header.CloudWatchEndpoint"
          }
        }
      }
    },
    "/route2": {
      "x-amazon-apigateway-any-method": {
        "parameters": [
          {
            "name": "CloudWatchEndpoint",
            "in": "header",
            "required": true,
            "type": "string",
            "default": "arn:aws:logs:us-east-1:123456789012:log-group:/aws/api-gateway/my-api-route2"
          }
        ],
        "x-amazon-apigateway-integration": {
          "type": "http",
          "httpMethod": "POST",
          "uri": "https://example.com",
          "passthroughBehavior": "when_no_templates",
          "requestParameters": {
            "integration.request.header.CloudWatchEndpoint": "method.request.header.CloudWatchEndpoint"
          }
        }
      }
    }
  }
}

在此示例中，每个路由都在parameters部分定义了一个名为CloudWatchEndpoint的属性，并在x
