如何使用 terraform 在 aws api 网关中添加 URL 查询字符串参数？

Question

我想在 API 中传递 account_id，如下所示https://exampleapi.com/dev?account_id=12345

这是创建 aws api 网关的 terraform 片段：

resource "aws_api_gateway_method" "example_api_method" {
  rest_api_id = "${aws_api_gateway_rest_api.example_api.id}"
  resource_id = "${aws_api_gateway_resource.example_api_resource.id}"
  http_method = "GET"
  authorization = "NONE"

}

resource "aws_api_gateway_integration" "example_api_method-integration" {
  rest_api_id = "${aws_api_gateway_rest_api.example_api.id}"
  resource_id = "${aws_api_gateway_resource.example_api_resource.id}"
  http_method = "${aws_api_gateway_method.example_api_method.http_method}"
  type = "AWS"
  uri = "arn:aws:apigateway:${var.aws_region}:lambda:path/functions/${var.lambda_arn}/invocations"
  integration_http_method = "GET"
}

提前致谢。

在此集成资源上，您可以使用request_templates参数并使用输入变量。如果你添加了喜欢的东西

resource "aws_api_gateway_integration" "example_api_method-integration" {
  rest_api_id = "${aws_api_gateway_rest_api.example_api.id}"
  resource_id = "${aws_api_gateway_resource.example_api_resource.id}"
  http_method = "${aws_api_gateway_method.example_api_method.http_method}"
  type = "AWS"
  uri = "arn:aws:apigateway:${var.aws_region}:lambda:path/functions/${var.lambda_arn}/invocations"
  integration_http_method = "GET"
  request_templates = {
  "application/json" = <<EOF
{
"account_id": "$util.escapeJavaScript($input.params().querystring.get("account_id))"
}
EOF
  }
}

在您的 terraform 中，您将获得一个名为 account_id 的查询字符串，并将其添加到您的事件中。输入变量文档中还有一个示例，显示如何解压查询字符串键下的所有查询字符串。
