* swarm/api: url scheme bzz-list for getting list of files from manifest Replace query parameter list=true for listing all files contained in a swarm manifest with a new URL scheme bzz-list. * swarm: replaace bzzr and bzzi schemes with bzz-raw and bzz-immutable New URI Shemes are added and old ones are deprecated, but not removed. Old Schemes bzzr and bzzi are functional for backward compatibility. * swarm/api: completely remove bzzr and bzzi schemes Remove old schemes in favour of bzz-raw and bzz-immutable. * swarm/api: revert "completely remove bzzr and bzzi schemes" Keep bzzr and bzzi schemes for backward compatibility. At least until 0.3 swarm release.

http roundtripper to register for bzz url scheme
|
|
see https://github.com/ethereum/go-ethereum/issues/2040
|
|
Usage:
|
|
|
|
import (
|
|
"github.com/ethereum/go-ethereum/common/httpclient"
|
|
"github.com/ethereum/go-ethereum/swarm/api/http"
|
|
)
|
|
client := httpclient.New()
|
|
// for (private) swarm proxy running locally
|
|
client.RegisterScheme("bzz", &http.RoundTripper{Port: port})
|
|
client.RegisterScheme("bzz-immutable", &http.RoundTripper{Port: port})
|
|
client.RegisterScheme("bzz-raw", &http.RoundTripper{Port: port})
|
|
|
|
The port you give the Roundtripper is the port the swarm proxy is listening on.
|
|
If Host is left empty, localhost is assumed.
|
|
|
|
Using a public gateway, the above few lines gives you the leanest
|
|
bzz-scheme aware read-only http client. You really only ever need this
|
|
if you need go-native swarm access to bzz addresses.
