Question

我有无服务器API，它使用无服务器框架版本1.25

由于安全原因，我想添加响应标头。请帮助我如何通过serverless.yml文件设置下面的标题。是否有必要为安全原因添加此标头？

•内容 - 安全 - 政策：包括default-src＆＃39; self＆＃39;

•Strict-Transport-Security max-age = 31536000; includeSubDomains;预加载

•X-Content-Type-Options：nosniff

•X-XSS-Protection：1

•缓存控制：max- age = 0; Expires = -1或Expires：Fri，1990年1月1日00:00:00 GMT; no-cache，must-revalidate

以下是我的无服务器应用程序serverless.yaml

service: myService
provider:
  name: aws
  runtime: nodejs6.10
  stage: dev
  region: eu-west-1
  environment:
    REGION: ${self:provider.region}
    PROJECT_NAME: ${self:custom.projectName}
    SERVERLESS_STAGE: ${self:provider.stage}
    SERVERLESS_SERVICE: ${self:service}
    IP_ADDRESS: http://example.com
functions:
   getMyFunction:
     handler: handler.getMyFunction
     timeout: 30
     events:
      - http:
          method: get
          path: api/getMyFunction/v1
          integration: lambda
          cors: true
          authorizer:
            name: authorizerFunc
            identitySource: method.request.header.Token
            authorizationType: AWS_IAM

Answer 1

您可以使用Lambda Proxy Integration。根据文档，您需要创建一个在有人访问您的API端点时运行的函数。

举个例子：

module.exports.hello = function（event，context，callback）{

console.log(event); // Contains incoming request data (e.g., query params, headers and more)

const response = {
  statusCode: 200,
  headers: {
    "x-custom-header" : "My Header Value"
  },
  body: JSON.stringify({ "message": "Hello World!" })
};

  callback(null, response);
};

在您的serverless.yml

中

functions:
 index:
   handler: handler.hello
   events:
     - http: GET hello

Answer 2

由于您使用Lambda Integration，因此必须将其放在serverless.yml。

中

service: myService
provider:
  name: aws
  runtime: nodejs6.10
  stage: dev
  region: eu-west-1
  environment:
    REGION: ${self:provider.region}
    PROJECT_NAME: ${self:custom.projectName}
    SERVERLESS_STAGE: ${self:provider.stage}
    SERVERLESS_SERVICE: ${self:service}
    IP_ADDRESS: http://example.com
functions:
   getMyFunction:
     handler: handler.getMyFunction
     timeout: 30
     events:
      - http:
          method: get
          path: api/getMyFunction/v1
          integration: lambda
          cors: true
          authorizer:
            name: authorizerFunc
            identitySource: method.request.header.Token
            authorizationType: AWS_IAM
          response:
            headers:
              Content-Security-Policy: "'Include default-src 'self''"
              Strict-Transport-Security: "'max-age=31536000; includeSubDomains; preload'"
              X-Content-Type-Options: "'nosniff'"
              X-XSS-Protection: "'1'"
              Cache-Control: "'max-age=0; Expires=-1 or Expires: Fri, 01 Jan 1990 00:00:00 GMT; no-cache, must-revalidate'"
