AWS负载均衡器的行为检查器默认会在http到https的301重定向中添加:80到URL中，这可能会导致问题。可以通过以下代码示例来禁用这种行为：

resource "aws_lb" "example" {
  ...

  enable_deletion_protection = true
  load_balancer_type         = "application"
  name                       = "example"
  internal                   = false

  access_logs {
    ...

    enabled = false
  }

  subnets             = ["subnet-12345678", "subnet-87654321"]
  security_groups     = ["sg-12345678"]
  idle_timeout        = 60
  enable_http2        = false
  ip_address_type     = "ipv4"

  tags = {
    Name = "example"
  }
}

resource "aws_lb_listener" "example" {
  ...

  default_action {
    ...

    redirect {
      ...

      port        = "443"
      protocol    = "HTTPS"
      status_code = "HTTP_301"
    }
  }
}

resource "aws_lb_target_group" "example" {
  ...

  target_type = "instance"
}

在以上代码示例中，通过将enable_http2设置为false，可以禁用HTTP/2。这样，AWS负载均衡器在http到https的301重定向中就不会添加:80到URL中了。
