The sample is described in the following topics.
This sample invokes twitter API and display results in a web app.
Need to access the appfactorypreview.wso2.com. We need to publish an API first in API Manager. You can create a API that gives Washington whether details in sandbox and London whether details in the production environment.
Executing the Sample
1. Create an application in AppFactory. Lets call it Customer Portal - cportal application. When you create an application in App Factory it will be automatically created in API-M.
2. Subscribe the application to the Weather API as follows:
- Click on cportal application in Home page.
- Click on 'Configure Resources' menu item.
- Go under 'APIs' section and click 'Subscribe' button.
- Go under 'Subscribe to an API' section and click 'Add Api' button.
- You will be redirected to API Manager Homepage (https://apimanager.appfactorypreview.wso2.com/store/).
- Click on 'twitter - 1.0.0' application.
- Select cportal from 'Applications' drop down and click 'Subscribe' button. You will get the 'Subscription Successful' pop-up.
3. Generate keys by clicking on the create dependencies.
4. Write your application to get keys by calling the CarbonContext and Registry APIs. The correct sandbox and production keys will be used depending on where the application is deployed. Here is the code to do that. Take the samples and commit it to your application location.
5. Deploy the application to "Development" environment and view results
6. Promote the application to "Production" environment and view results.
The results of Development environment differs from Production environment because the keys that is used by the two environments are different. The programmer is unaware about the sandbox and production keys, and everything is handled underneath.
