goose

Installation

$ go get "github.com/politician/goose"
$ go install

Usage

$ goose

Starts up the various services, and waits for connections.

Create a watch

$ curl -X POST --data "{\"tag\":\"opaque-id-1234\",\"dataSourceName\":\"data-access-service\",\"matchExpr\":{\"method\":\"GET\",\"path\":\"/foo\"},\"echo\":{\"status\":200,\"headers\":{},\"body\":\"hello, world\"}}" http://127.0.0.1:8080/watches
{"id": 1}

Query a watched endpoint

$ curl http://127.0.0.1:8081/foo
hello, world

Redis Integration

If you're running Redis, goose will store any incoming requests as hashes and LPUSH the hash keys onto the list specified as the tag field in a watch. If the tag is not specified, goose will generate a new tag and include it in the create watch response.

Example

In the following example, we'll start up goose as a background job, set up a watch such that requests will be saved in a redis list named exampletag, curl the watched endpoint, then verify that redis contains the request using telnet.

$ goose -redis localhost:6379 &
$ curl -X POST --data "{\"tag\":\"exampletag\",\"dataSourceName\":\"data-access-service\",\"matchExpr\":{\"method\":\"GET\",\"path\":\"/foo\"},\"echo\":{\"status\":200,\"headers\":{},\"body\":\"hello, world\"}}" http://127.0.0.1:8080/watches
{"id": 1}
$ curl -X GET --data "stuff & things" http://127.0.0.1:8081/foo
hello, world
$ telnet localhost 6379
