【问题描述】：

我正在尝试使用 AWS API Gateway 提供静态内容。 当我尝试从测试页面和 curl 调用 URL 时，我收到错误：

“由于配置错误导致执行失败：statusCode应该是请求模板中定义的整数”。

这是我在 Terraform 上的配置：

resource "aws_api_gateway_rest_api" "raspberry_api" 
  name        = "raspberry_api"


resource "aws_acm_certificate" "raspberry_alexa_mirko_io" 
  domain_name       = "raspberry.alexa.mirko.io"
  validation_method = "DNS"

  lifecycle 
    create_before_destroy = true
  


resource "aws_route53_record" "raspberry_alexa_mirko_io_cert_validation" 
  name    = aws_acm_certificate.raspberry_alexa_mirko_io.domain_validation_options.0.resource_record_name
  type    = aws_acm_certificate.raspberry_alexa_mirko_io.domain_validation_options.0.resource_record_type
  zone_id = var.route53_zone_id
  records = [aws_acm_certificate.raspberry_alexa_mirko_io.domain_validation_options.0.resource_record_value]
  ttl     = 60


resource "aws_route53_record" "raspberry_alexa_mirko_io" 
  zone_id = var.route53_zone_id
  name = aws_acm_certificate.raspberry_alexa_mirko_io.domain_name
  type = "A"
  alias 
    name = aws_api_gateway_domain_name.raspberry_alexa_mirko_io.cloudfront_domain_name
    zone_id = aws_api_gateway_domain_name.raspberry_alexa_mirko_io.cloudfront_zone_id
    evaluate_target_health = true
  


resource "aws_acm_certificate_validation" "raspberry_alexa_mirko_io" 
  certificate_arn         = aws_acm_certificate.raspberry_alexa_mirko_io.arn
  validation_record_fqdns = [aws_route53_record.raspberry_alexa_mirko_io_cert_validation.fqdn]
  provider = aws.useast1


resource "aws_api_gateway_domain_name" "raspberry_alexa_mirko_io" 
  certificate_arn = aws_acm_certificate_validation.raspberry_alexa_mirko_io.certificate_arn
  domain_name     = aws_acm_certificate.raspberry_alexa_mirko_io.domain_name


resource "aws_api_gateway_base_path_mapping" "raspberry_alexa_mirko_io_base_path_mapping" 
  api_id      = aws_api_gateway_rest_api.raspberry_api.id
  domain_name = aws_api_gateway_domain_name.raspberry_alexa_mirko_io.domain_name


resource "aws_api_gateway_resource" "home" 
  rest_api_id = aws_api_gateway_rest_api.raspberry_api.id
  parent_id   = aws_api_gateway_rest_api.raspberry_api.root_resource_id
  path_part   = "login"


resource "aws_api_gateway_method" "login" 
  rest_api_id   = aws_api_gateway_rest_api.raspberry_api.id
  resource_id   = aws_api_gateway_resource.home.id
  http_method   = "GET"
  authorization = "NONE"


resource "aws_api_gateway_integration" "integration" 
  rest_api_id             = aws_api_gateway_rest_api.raspberry_api.id
  resource_id             = aws_api_gateway_resource.subscribe_raspberry.id
  http_method             = aws_api_gateway_method.subscribe.http_method
  integration_http_method = "POST"
  type                    = "AWS_PROXY"
  uri                     = aws_lambda_function.raspberry_lambda.invoke_arn
  # This was just a failed attempt. It did not fix anything
  request_templates = 
    "text/html" = "\"statusCode\": 200"
  


resource "aws_api_gateway_integration" "login_page" 
  rest_api_id          = aws_api_gateway_rest_api.raspberry_api.id
  resource_id          = aws_api_gateway_resource.home.id
  http_method          = aws_api_gateway_method.login.http_method
  type                 = "MOCK"
  timeout_milliseconds = 29000


resource "aws_api_gateway_method_response" "response_200" 
  rest_api_id = aws_api_gateway_rest_api.raspberry_api.id
  resource_id = aws_api_gateway_resource.home.id
  http_method = aws_api_gateway_method.login.http_method
  status_code = "200"


resource "aws_api_gateway_integration_response" "login_page" 
  rest_api_id = aws_api_gateway_rest_api.raspberry_api.id
  resource_id = aws_api_gateway_resource.home.id
  http_method = aws_api_gateway_method.login.http_method
  status_code = aws_api_gateway_method_response.response_200.status_code
  response_templates = 
    "text/html" = data.template_file.login_page.rendered
  


resource "aws_api_gateway_deployment" "example" 
  depends_on = [
    aws_api_gateway_integration.login_page
  ]
  rest_api_id = aws_api_gateway_rest_api.raspberry_api.id
  stage_name  = "production"

我已按照this blog 中的说明进行操作，但没有成功。

【问题讨论】：

一个简单的错字。你输入status_code = "200"，这是一个字符串。所需的数据类型是数字，即status_code = 200。事后看来，错误消息试图给你这个提示;-)

@SherylHohman 谢谢，我花了几个小时没有成功。真的很感激......

【参考方案1】：

“200”（带引号）被认为是一个字符串，而不是一个整数

试试status_code = 200（不带引号）

【讨论】：

我这样做了，但仍然收到错误“由于配置错误导致执行失败：statusCode 应该是请求模板中定义的整数”:(

【参考方案2】：

只是在这里转发the excellent answer of TheClassic，格式好像是：

request_templates = 
  "application/json" = jsonencode(
    
      statusCode = 200
    
  )

我也遇到了同样的问题，但看起来这可行。

【参考方案3】：

根据 Bernie 的评论，需要在 aws_api_gateway_integration terraform 资源的 request_templates 属性中明确提供此状态代码。

添加后，我终于得到了 200 个通过 MOCK 端点集成的 OPTIONS。

【参考方案4】：

我遇到了同样的错误，因为我的代码事先看起来像这样 - 受到 terraform 文档的启发。

resource "aws_api_gateway_integration" "api_gateway" 
  http_method = aws_api_gateway_method.api_gateway.http_method
  resource_id = aws_api_gateway_resource.api_gateway.id
  rest_api_id = aws_api_gateway_rest_api.api_gateway.id
  type        = "MOCK"

阅读此主题后，它现在的工作方式如下：

resource "aws_api_gateway_integration" "api_gateway" 
  http_method = aws_api_gateway_method.api_gateway.http_method
  resource_id = aws_api_gateway_resource.api_gateway.id
  rest_api_id = aws_api_gateway_rest_api.api_gateway.id
  type        = "MOCK"
  request_templates = 
    "application/json" = jsonencode(
      
        statusCode = 200
      
    )
  

【参考方案5】：

对于可能会看到这一点的其他人，此错误也可能是由于需要验证当您使用 Mock 作为您的集成类型时，您确认您的 RequestTemplates 包含 statusCode 并且 statusCode 的值等于您的 IntegrationResponses 之一/ResponseTemplates/StatusCode

类似：

    requestTemplates: 
      "application/json": "\"statusCode\": 200"
