如何使用aws cdk记录rest api

问题描述 投票:0回答:1

[我正在使用AWS CDK 1.22版创建REST API,我也想使用CDK记录我的API,但是在部署后看不到为我的API生成任何文档。

我已经深入到aws文档,cdk示例,cdk参考,但是我可以找到具体的示例来帮助我理解如何做。

这是我的代码:

const app = new App();
const api = new APIStack(app, 'APIStack', { env }); // basic api gateway

// API Resources
const resourceProps: APIResourceProps = {
  gateway: api.gateway,
}

// dummy endpoint with some HTTP methods
const siteResource = new APISiteStack(app, 'APISiteStack', {
  env,
  ...resourceProps
});

const siteResourceDocs = new APISiteDocs(app, 'APISiteDocs', {
  env,
  ...resourceProps,
});

// APISiteDocs is defined as follow:
class APISiteDocs extends Stack {

  constructor(scope: Construct, id: string, props: APIResourceProps) {
    super(scope, id, props);

    new CfnDocumentationVersion(this, 'apiDocsVersion', {
      restApiId: props.gateway.restApiId,
      documentationVersion: config.app.name(`API-${config.gateway.api.version}`),
      description: 'Spare-It API Documentation',
    });

    new CfnDocumentationPart(this, 'siteDocs', {
      restApiId: props.gateway.restApiId,
      location: {
        type: 'RESOURCE',
        method: '*',
        path: APISiteStack.apiBasePath,
        statusCode: '405',
      },
      properties: `
        {
          "status": "error",
          "code": 405,
          "message": "Method Not Allowed"
        }
      `,
    });
  }
}

感谢任何帮助/提示,​​谢谢。

据我所知,如果您使用CDK的默认部署选项(代表您创建阶段和部署),将无法在阶段中附加文档版本集。

相反,解决方案是将RESTAPI的选项对象设置为deploy:false并手动定义阶段和部署。

stack.ts代码

import * as cdk from '@aws-cdk/core';
import * as apigateway from '@aws-cdk/aws-apigateway';
import { Stage, Deployment, CfnDocumentationPart, CfnDocumentationVersion, CfnDeployment } from '@aws-cdk/aws-apigateway';

export class StackoverflowHowToDocumentRestApiUsingAwsCdkStack extends cdk.Stack {
  constructor(scope: cdk.Construct, id: string, props?: cdk.StackProps) {
    super(scope, id, props);

    // create the API, need to not rely on CFN's automatic deployment because we need to 
    // make our own deployment to set the documentation we create
    const api = new apigateway.RestApi(this, 'books-api',{
      deploy: false
    });

    // create GET method on /books resource
    const books = api.root.addResource('books');
    books.addMethod('GET');

    // // create documentation for GET method
    const docpart = new CfnDocumentationPart(this, 'doc-part1', {
      location: {
        type: 'METHOD',
        method: 'GET',
        path: books.path
      },
      properties: JSON.stringify({
        "status": "successful",
        "code": 200,
        "message": "Get method was succcessful"
      }),
      restApiId: api.restApiId
    });

    const doc = new CfnDocumentationVersion(this, 'docVersion1', {
      documentationVersion: 'version1',
      restApiId: api.restApiId,
      description: 'this is a test of documentation'
    });
    // not sure if this is necessary but it made sense to me
    doc.addDependsOn(docpart);

    const deployment = api.latestDeployment ? api.latestDeployment: new Deployment(this,'newDeployment',{
      api: api,
      description: 'new deployment, API Gateway did not make one'
    });
    // create stage of api with documentation version
    const stage = new Stage(this, 'books-api-stage1', {
      deployment:  deployment,
      documentationVersion: doc.documentationVersion,
      stageName: 'somethingOtherThanProd'
    });
  }
}

输出

APIGateway web console
