[Question] Usage about selector peer

[Yw-melo]

客户端调用后无法通过selector.FromPeerContext拿到 selector peer，发现是下面两行覆盖了peerKey，这样的话只能在源码中拿到peer，无法在客户端调用后拿到 https://github.com/go-kratos/kratos/blob/85740b179b097d3ba63ff873819bfc1d8ab28899/transport/http/client.go#L272-L273

如果改成没有peerKey的时候在去new会不会好些，这样经过 newPeer ->客户端调用->fromPeer即可拿到peer

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

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. https://github.com/go-kratos/kratos/blob/85740b179b097d3ba63ff873819bfc1d8ab28899/transport/http/client.go#L272-L273

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)
}

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!
