Question

我想使用一个摇摇欲坠的文件来描述我的api，并使用terraform来部署我的api网关。 swagger.yaml看起来像这样：

swagger: '2.0'
info:
  version: '1.0'
  title: "CodingTips"
schemes:
  - https
paths:
  "/api":
    get:
      description: "Get coding tips"
      produces:
        - application/json
      x-amazon-apigateway-integration: ${apiIntegration}
      responses:
        '200':
          description: "Codingtips were successfully requested"

Terraform给我一个BadRequestException，说The REST API doesn't contain any methods。

因此，我认为它正在尝试部署REST api，而不等待该api的方法和集成被创建。

这使我开始思考必须将DEPENDS_ON添加到aws_api_gateway_deployment的方向。但是我不知道要依赖什么，因为我没有使用swagger定义方法和集成资源。应该从大摇大摆的定义中自动扣除它们。

我是否在朝着正确的方向思考，如果是，我该如何使aws_api_gateway_deployment赖以生存？还是我尝试部署此api的方式有其他问题。

我的apigateway.tf文件如下：

resource "aws_api_gateway_rest_api" "codingtips-api-gateway" {
  name        = "ServerlessExample"
  description = "Terraform Serverless Application Example"
  body        = "${data.template_file.codingtips_api_swagger.rendered}"
}

locals{
  "get_codingtips_arn" = "${aws_lambda_function.get-tips-lambda.invoke_arn}"

  "x-amazon-coding-tips-apigateway-integration" = <<EOF
#
uri = "${local.get_codingtips_arn}"
passthroughBehavior: when_no_match
httpMethod: POST
type: aws_proxy
credentials: "${aws_iam_role.api_gateway_role.arn}"
EOF
}

data "template_file" codingtips_api_swagger{
  template = "${file("./swagger.yaml")}"

  vars {
    apiIntegration = "${indent(8, local.x-amazon-coding-tips-apigateway-integration)}"
  }
}

resource "aws_api_gateway_deployment" "codingtips-api-gateway-deployment" {
  rest_api_id = "${aws_api_gateway_rest_api.codingtips-api-gateway.id}"
  stage_name  = "test"
}

如何修复BadRequestException: The REST API doesn't contain any methods？

Answer 1

我发现了问题所在。这是locals{}块中的语法错误。 uri =应该是uri:。使用冒号而不是等号。然后，该块如下所示：

locals{
  "get_codingtips_arn" = "${aws_lambda_function.get-tips-lambda.invoke_arn}"

  "x-amazon-codingtips-get-apigateway-integration" = <<EOF
# comment for new line
uri: "${aws_lambda_function.get-tips-lambda.invoke_arn}"
passthroughBehavior: when_no_match
httpMethod: POST
type: aws_proxy
EOF
}

对此进行了研究，我发现，当您在swagger.yaml中指定x-amazon-apigateway-integration时，这样阅读起来会更容易：

swagger: '2.0'
info:
  version: '1.0'
  title: "CodingTips"
schemes:
  - https
paths:
  "/api":
    get:
      description: "Get coding tips"
      produces:
        - application/json
      responses:
        '200':
          description: "The codingtips request was successful."
      x-amazon-apigateway-integration:
        uri: ${uri_arn}
        passthroughBehavior: "when_no_match"
        httpMethod: "POST"
        type: "aws_proxy"

您的Terraform中的data{}和locals{}块如下所示：

data "template_file" codingtips_api_swagger{
  template = "${file("swagger.yaml")}"

  vars {
    uri_arn = "${local.get_codingtips_arn}"
  }
}

locals {
  "get_codingtips_arn" = "${aws_lambda_function.get-tips-lambda.invoke_arn}"
}

根据摇摇欲坠的文件使用Terraform部署API网关
