如何使用同一根模块中的输出值来创建另一个资源

上下文：这是我提出的以下帖子的延续在Terraform 中使用for_each创建多个子网时出现问题

目标：如何使用创建的一个资源的输出值，并将其用于在同一根模块中创建另一个资源

我尝试了什么：

resource "azurerm_virtual_network" "vnet" {
name                = var.hub_vnet_name
location            = azurerm_resource_group.rg[0].location
resource_group_name = azurerm_resource_group.rg[0].name
for_each = {for k,v in var.vnet_address_space: k=>v if k == "${var.env}"}
address_space       =  each.value
dns_servers         = var.dns_servers
tags     = {
environment = "${var.env}"
costcentre = "14500"
}
dynamic "ddos_protection_plan" {
for_each = local.if_ddos_enabled
content {
id     = azurerm_network_ddos_protection_plan.ddos[0].id
enable = false
}
}
}
output "azurerm_vnets_names" {
value = values(azurerm_virtual_network.vnet)[*].name

}

直到上面的点它的工作，我看到的输出

Outputs:
azurerm_vnets_names = [
"vnet-hub",
]

现在，作为下一步，我正试图在下面的循环中创建子网

tfvars.json:

"subnets" : {
"Dev" :
[  
{"gw_snet":{
"name"                 : "GatewaySubnet",
"address_prefixes"     : ["10.1.1.0/24"]
},
"dns-snet" : {
"name"                 : "InboundDNSSubnet",
"address_prefixes"     : ["10.1.2.0/24"]
},
"common_snet" : {
"name"                 : "Common",
"address_prefixes"     : ["10.1.3.0/24"]
},
"clientdata_snet" : {
"name"                 : "ClientDataSubnet",
"address_prefixes"     : ["10.1.4.0/20"]
}}
],
"Stage" :
[  
{"gw_snet":{
"name"                 : "GatewaySubnet",
"address_prefixes"     : ["10.2.1.0/24"]
},
"dns-snet" : {
"name"                 : "InboundDNSSubnet",
"address_prefixes"     : ["10.2.2.0/24"]
},
"common_snet" : {
"name"                 : "Common",
"address_prefixes"     : ["10.2.3.0/24"]
},
"clientdata_snet" : {
"name"                 : "ClientDataSubnet",
"address_prefixes"     : ["10.2.4.0/20"]
}}
],
"Prod" :
[  
{"gw_snet":{
"name"                 : "GatewaySubnet",
"address_prefixes"     : ["10.3.1.0/24"]
},
"dns-snet" : {
"name"                 : "InboundDNSSubnet",
"address_prefixes"     : ["10.3.2.0/24"]
},
"common_snet" : {
"name"                 : "Common",
"address_prefixes"     : ["10.3.3.0/24"]
},
"clientdata_snet" : {
"name"                 : "ClientDataSubnet",
"address_prefixes"     : ["10.3.4.0/20"]
}}
]
}  

在我的主页中。tf:

locals {
net_subnets = merge([
for env, network in var.subnets : {
for k, v in network[0] :
"${k}-${v.name}" => {
subnet_name      = v.name
address_prefixes = v.address_prefixes
} if env == "Dev"
}]...)
}

#Creating subnets
resource "azurerm_subnet" "mysubnet" {
for_each             = local.net_subnets
name                 = each.value.subnet_name
address_prefixes     = each.value.address_prefixes
virtual_network_name = azurerm_virtual_nework.vnet.name
resource_group_name  = var.resource_group_name
}

现在下面的行正在出错

virtual_network_name = azurerm_virtual_nework.vnet.name

说"；因为我在创建vnet时使用了for_each，所以我不能使用上面的

现在，由于我看到了我在上面定义的输出变量azurerm_vnets_names，我试图将其称为

virtual_network_name = azurerm_vnets_names

不起作用

然后

我尝试添加数据源

data "azurerm_virtual_network" "vnet" {
name                = "vnet-hub"
resource_group_name = "hub"
}

然后在下面尝试：

virtual_network_name = data.azurerm_virtual_nework.vnet.name

再一次错误说。。它没有宣布。

我也试过下面的一个，没有工作

virtual_network_name = azurerm_virtual_network.vnet[*].name

请帮我找出问题。
