http-cache-middleware

http-cache-middleware is a high performance http cache using redis, ideal for RESFful API. To maximize simplicity, the implementation using built-in net/http package, though code can be simplified using frameworks like Gin, beego, etc.

Cache expires after 10 mins by default, and can be configured for whatever.

This middleware should used behined auth, a simple auth+value key is used for user-specified cache naively.

How to run

Autopilot Access Key

To run the middleware, make sure you have a plain text file named access under the project folder, containing autopilot api key.

Redis

Make sure redis running on port 6379. Or you can modify the default in code in main.go.

Run Application

To run the middleware, simply run:

$ go run main.go

or

$ go build

and run the built binary.

The service is running on port 8080 by default and the endpoint is /contact supporting GET, POST, PUT, DELETE.

To test the api, use tools like postman or use the scripts under scripts which use cURL. Remember to replace ACCESSKEY in scripts with your api key. You may need to change the method from PUT to POST in add.sh.

Go Test

To ultilize modularization, each module has its own test, simply go to each package and run:

$ go test -v

Do forget to enter your access key in api_test.go to pass the test.

Possible Improvements

• Server-side cache refresh from autopilot
• More robust test to improve coverage
• Light-weight framework like Gin can be used to simplify code
