Hi all, Publishing APIs into APIM from Tomcat based AS 6.0 - Architecture
The idea of the above is to automatically create APIs from the deployed web apps in AS and publish them into the API Publisher. Publishing APIs automatically makes it easier for webapp developers on Tomcat to use APIM easier. Right now, the users has to manually create Managed APIs for their REST-ful web apps. As part of this effort, the API gateway will be included within Tomcat based AS itself. This is used to validate whether the request from that end user have permission to access that API. So the AS will have an integrated API gateway to validate. The api everywhere for AS 6.0 have 3 main components, 1. API Scanner 2. API Creator 3. Integrated API gateway API Scanner component will scan the deployed web app and create APIs. In web app deployment time the API scanner will scan the annotations and configurations and generate APIs and API informations. API Creator will publish the APIs into API Publisher. For that user have to provide the “clientId” and “clientSecret” of OAuth 2.0. Access token will be request from the APIM Key manager. Then using that access token the generated APIs will be published into APIM. The API will be in the “CREATED” state, the webapp developers can edit and publish as their wish. API Creator will be a running on new thread to reduce the web app startup time. Integrated API gateway will intercept the request into AS. The access token of the request will be validated with APIM key manager. If the token have the right to access the web app, the request will be passed or otherwise an exception will be thrown to the end user. Until now implementation of API Scanner and API Creator are completed and working PoC is available. We have to decide which information we are going to publish into the API publisher. There are some items like tags, business information and etc which are not compulsory when creating APIs. [image: Inline image 1] -- K.Senthalan, Software Engineering Intern, WSO2 Inc.
