[Question] Usage about selector peer about kratos

[dosubot]

Hi, @Yw-melo

I'm helping the Kratos team manage their backlog and am marking this issue as stale. From what I understand, the issue was related to the inability to retrieve the selector peer using selector.FromPeerContext after a client call due to the peerKey being overwritten in the code. The suggestion was to modify the code to avoid overwriting the peerKey, which would allow for retrieving the peer after a client call. The issue has been resolved by modifying the code to avoid overwriting the peerKey, which now allows for retrieving the peer using selector.FromPeerContext after a client call. Assistance was provided by me.

Could you please confirm if this issue is still relevant to the latest version of the Kratos repository? If it is, please let the Kratos team know by commenting on the issue. Otherwise, feel free to close the issue yourself or the issue will be automatically closed in 7 days.

Thank you!

After the client calls, the selector peer cannot be obtained through selector.FromPeerContext. It is found that the following two lines cover the peerKey. In this case, the peer can only be obtained in the source code and cannot be obtained after the client calls.

kratos/transport/http/client.go

Lines 272 to 273 in 85740b1

	var p selector.Peer
	ctx = selector.NewPeerContext(ctx, &p)

Would it be better to go to new when there is no peerKey, so that you can get the peer through newPeer -> client call -> fromPeer

_, ok := selector.FromPeerContext(ctx)
if !ok {
    var p selector.Peer
    ctx = selector.NewPeerContext(ctx, &p)
}
