Support for basic authentication as part of the URL

[barnabasbusa]

Looks like basic authentication is not supported in dshackle.

Is there any quick way to enable this?

Example:
config:

cluster:
      upstreams:
        - id: "geth-lighthouse"
          chain: ethereum
          connection:
            ethereum:
              rpc:
                url: "https://username:pass@rpc.lighthouse-geth-001.srv.holesky.ethpandaops.io"

dshackle logs:

Raw curl to the rpc endpoint

curl --data '{"method":"eth_blockNumber","params":[],"id":1,"jsonrpc":"2.0"}' -H "Content-Type: application/json" -X POST  https://username:password@rpc.lighthouse-geth-001.srv.holesky.ethpandaops.io

response:

{"jsonrpc":"2.0","id":1,"result":"0x207"}

Did you try to specify it as basic-auth option? https://github.com/emeraldpay/dshackle/blob/master/docs/reference-configuration.adoc#ethereum-connection-options

PS I guess it's possible to extract from the URL as well, but at this time I could suggest to use the config option

Yeah,I wasn't aware of this field. Thanks it is working using this extra field, but indeed it would be great if the standard method with the prefixed username:pass method would also be supported out of the box.

Also it would be great if custom auth headers could also be passed, not just basic auth. For example something like this: https://developers.cloudflare.com/cloudflare-one/identity/service-tokens/#connect-your-service-to-access
