在aws_api_gateway_gateway_response中设置字段status_code的默认值

Question

我正在尝试修改 api 网关错误响应的模板。以下是 AWS API 网关中可能出现的错误情况，

REQUEST_TOO_LARGE
RESOURCE_NOT_FOUND
AUTHORIZER_CONFIGURATION_ERROR
MISSING_AUTHENTICATION_TOKEN
BAD_REQUEST_BODY
INVALID_SIGNATURE
INVALID_API_KEY
BAD_REQUEST_PARAMETERS
AUTHORIZER_FAILURE
UNAUTHORIZED
INTEGRATION_TIMEOUT
ACCESS_DENIED
DEFAULT_4XX
DEFAULT_5XX
WAF_FILTERED
QUOTA_EXCEEDED
THROTTLED
API_CONFIGURATION_ERROR
UNSUPPORTED_MEDIA_TYPE
INTEGRATION_FAILURE
EXPIRED_TOKEN

这是我的资源，

resource "aws_api_gateway_gateway_response" "api_gateway_response" {
count         = length(var.api_gateway_response_types)
rest_api_id   = aws_api_gateway_rest_api.api_gateway.id
response_type = element(values(var.api_gateway_response_types), count.index) 
response_templates = {
"application/json" = "{"errors": [{"errorCode": "${element(keys(var.api_gateway_response_types), count.index)}", "message": $context.error.messageString}]}"
}
}

在这里，我只想更改响应模板并保留status_code。status_code是资源aws_api_gateway_gateway_response的可选字段，但如果您不传递status_code，它将显示为status_code正在更改terraform plan。

所以每次你检查terraform plan.它将显示如下，

# aws_api_gateway_gateway_response.api_gateway_response[0] will be updated in-place
~ resource "aws_api_gateway_gateway_response" "api_gateway_response" {
id                  = "aggr-gohnlccgwh-REQUEST_TOO_LARGE"
response_parameters = {}
response_templates  = {
"application/json" = "{"errors": [{"errorCode": "4001", "message": $context.error.messageString}]}"
}
response_type       = "REQUEST_TOO_LARGE"
rest_api_id         = "gohnlccgwh"
- status_code         = "413" -> null
}
# aws_api_gateway_gateway_response.api_gateway_response[1] will be updated in-place
~ resource "aws_api_gateway_gateway_response" "api_gateway_response" {
id                  = "aggr-gohnlccgwh-RESOURCE_NOT_FOUND"
response_parameters = {}
response_templates  = {
"application/json" = "{"errors": [{"errorCode": "4002", "message": $context.error.messageString}]}"
}
response_type       = "RESOURCE_NOT_FOUND"
rest_api_id         = "gohnlccgwh"
- status_code         = "404" -> null
}

所以我想通过从 API 网关获取它来设置默认status_code。 所以我尝试如下，

resource "aws_api_gateway_gateway_response" "api_gateway_response" {
count         = length(var.api_gateway_response_types)
rest_api_id   = aws_api_gateway_rest_api.api_gateway.id
response_type = element(values(var.api_gateway_response_types), count.index)
status_code = aws_api_gateway_gateway_response.api_gateway_response[count.index].status_code
response_templates = {
"application/json" = "{"errors": [{"errorCode": "${element(keys(var.api_gateway_response_types), count.index)}", "message": $context.error.messageString}]}"
}
}

在这里，我尝试将当前代码设置为status_code = aws_api_gateway_gateway_response.api_gateway_response[count.index].status_code。但它导致了循环错误。

Error: Cycle: aws_api_gateway_gateway_response.api_gateway_response[16], aws_api_gateway_gateway_response.api_gateway_response[12], aws_api_gateway_gateway_response.api_gateway_response[11], aws_api_gateway_gateway_response.api_gateway_response[7], aws_api_gateway_gateway_response.api_gateway_response[19], aws_api_gateway_gateway_response.api_gateway_response[3], aws_api_gateway_gateway_response.api_gateway_response[9], aws_api_gateway_gateway_response.api_gateway_response[18], aws_api_gateway_gateway_response.api_gateway_response[10], aws_api_gateway_gateway_response.api_gateway_response[13], aws_api_gateway_gateway_response.api_gateway_response[14], aws_api_gateway_gateway_response.api_gateway_response[17], aws_api_gateway_gateway_response.api_gateway_response[0], aws_api_gateway_gateway_response.api_gateway_response[15], aws_api_gateway_gateway_response.api_gateway_response[8], aws_api_gateway_gateway_response.api_gateway_response[1], aws_api_gateway_gateway_response.api_gateway_response[2], aws_api_gateway_gateway_response.api_gateway_response[20], aws_api_gateway_gateway_response.api_gateway_response[4], aws_api_gateway_gateway_response.api_gateway_response[6], aws_api_gateway_gateway_response.api_gateway_response[5]

有人可以在这里帮助我吗？

这有点像逃避，但您可以制作自己的地图，其中可能存在错误情况以及默认状态代码。例如，我更改了地形中默认的 4xx 错误。但是，我希望所有其他 400 个响应都保留其原始状态代码和错误响应。我用地图和这样的循环for_each做到了这一点

resource "aws_api_gateway_gateway_response" "400_responses" {
for_each = {
ACCESS_DENIED          = 403
BAD_REQUEST_BODY       = 400
BAD_REQUEST_PARAMETERS = 400
EXPIRED_TOKEN          = 403
INVALID_API_KEY        = 403
INVALID_SIGNATURE      = 403
QUOTA_EXCEEDED         = 429
REQUEST_TOO_LARGE      = 413
RESOURCE_NOT_FOUND     = 404
THROTTLED              = 429
UNAUTHORIZED           = 401
UNSUPPORTED_MEDIA_TYPE = 415
WAF_FILTERED           = 403
}
response_type = each.key
status_code   = each.value
rest_api_id   = aws_api_gateway_rest_api.example_api.id
response_templates = {
"application/json" = "{"message":$context.error.messageString}"
}
}
