httpsniffer

A work-in-progress framework to build HTTP-based sniffers in an easy way. Just register your handlers and it handles everything for you as simple as creating an HTTP Server.

It builds on the battle-hardened gopacket, and it adds support for parsing HTTP requests and responses using net/http.

NOTE: the API is still under heavy development, therefore subject to substantial changes.

Quick Example

func main() {
    device := "eth0"
    port := 80
    sniffer := New(device, port)

    // you can register as many handlers you want
    // httpsniffer will chain the request through them in the order they were registered
    // the output of each handler will the input of the next handler
    sniffer.Register(func(txn *Transaction) (*Transaction, error) {
        fmt.Println(txn.Request)
        fmt.Println(txn.Response)
        return txn, nil
    })

    // starts the sniffing for HTTP request on device eth0 and port 80
    sniffer.Listen()
}
