capture

Capture is a reverse proxy that takes an incoming HTTP request and sends it to another server, proxying the response back to the client, while showing them in a dashboard

Running

./capture -url=https://example.com/

Settings

Using

If you set your base url as http://example.com/api, now http://localhost:9000 points to that address. Hence, calling http://localhost:9000/users/1 is like calling http://example.com/api/users/1

Capture saves all requests and responses so that you can see them in the dashboard

Dashboard

To access the dashboard go to http://localhost:9001/

Preview

Building

Manually:

git clone --depth 1 https://github.com/ofabricio/capture.git
cd capture
go build -o capture .

Via docker:

git clone --depth 1 https://github.com/ofabricio/capture.git
cd capture
docker run --rm -v $(pwd):/src -w /src -e GOOS=darwin -e GOARCH=amd64 golang:alpine go build -o capture 

Now you have an executable binary in your directory

Note: you can change GOOS=darwin to linux or windows to create an executable for your corresponding Operating System

Plugins

Put plugin files in the current directory. They are loaded sorted by filename on startup.

Plugins must export the following function:

func Handler(proxy http.HandlerFunc) http.HandlerFunc {
    return func(rw http.ResponseWriter, r *http.Request) {
        proxy.ServeHTTP(rw, r)
    }
}
