我正在尝试使用Terraform部署AWS API网关，并得到以下错误
Error: Error creating API Gateway Integration: BadRequestException: Invalid mapping expression specified: Validation Result: warnings : [], errors : [Invalid mapping expression specified: arn:aws:sns:us-west-2:************:com-service-receive-notification-inbound]
on Apps/CommunicationService/api-gateway.tf line 97, in resource "aws_api_gateway_integration" "integration_get":
97: resource "aws_api_gateway_integration" "integration_get" {
这个想法是部署一个API网关并将其与SNS集成，下面是我的GET方法和GET集成的一个片段
resource "aws_api_gateway_method" "method_get" {
count = var.application_enabled ? 1 : 0
rest_api_id = aws_api_gateway_rest_api.api_trumpic[count.index].id
resource_id = aws_api_gateway_resource.resource_trumpic[count.index].id
http_method = "GET"
authorization = "NONE"
request_parameters = {
"method.request.path.proxy" = true
"method.request.querystring.xml" = true
"method.request.querystring.Message" = true
"method.request.querystring.TopicArn" = true
# "method.request.querystring.message" = true
# "method.request.querystring.PhoneNumber" = true
}
}
resource "aws_api_gateway_integration" "integration_get" {
count = var.application_enabled ? 1 : 0
rest_api_id = aws_api_gateway_rest_api.api_trumpic[count.index].id
resource_id = aws_api_gateway_resource.resource_trumpic[count.index].id
http_method = aws_api_gateway_method.method_get[count.index].http_method
credentials = aws_iam_role.cloudwatch[count.index].arn
integration_http_method = "GET"
type = "AWS"
uri = "arn:aws:apigateway:us-west-2:sns:path//"
request_parameters = {
# "integration.request.querystring.Message" = "method.request.querystring.message",
# "integration.request.querystring.Subject" = "method.request.querystring.from",
"integration.request.querystring.Message" = "method.request.querystring.xml"
"integration.request.querystring.TopicArn" = "${aws_sns_topic.com-service-receive-notification-inbound[count.index].arn}"
}
}
所以我发现一切都是正确的，我错过了"，这就是问题所在。
"integration.request.querystring.TopicArn" = "'${aws_sns_topic.com-service-receive-notification-inbound[count.index].arn}'"
