capture/README.md

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.

Forked from ofabricio/capture.

Running

./capture -url=https://example.com/ -port 9000 -dashboard 9001 -captures 16

Via docker:

docker run -p 9000:9000 -p 9001:9001 deblan/capture -url=https://example.com/ -port 9000 -dashboard 9001 -captures 16

Settings

param	description
-url	Required. Set the url you want to proxy
-port	Set the proxy port. Default: 9000
-dashboard	Set the dashboard port. Default: 9001
-captures	Set how many captures to show in the dashboard. Default: 16
-tls-skip-verify	Skip TLS vertificaton. Default: false
-config	Set the configuration file. Default: .capture.ini

You can create a file named .capture.ini and set the configuration inside:

url = https://example.com/
port = 9000
dashboard = 9001
captures = 16
tls_skip_verify = false

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://127.0.0.1:9001/

Preview

Building

Manually:

git clone --depth 1 https://gitnet.fr/deblan/capture.git
cd capture
go build

Via docker:

git clone --depth 1 https://gitnet.fr/deblan/capture.git
cd capture
docker run --rm -v $PWD:/src -w /src -e GOOS=darwin -e GOARCH=amd64 golang:alpine go build

Now you have an executable binary in your directory.

Note: 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(w http.ResponseWriter, r *http.Request) {
        proxy(w, r)
    }
}
