具体执行步骤

1. 添加IBC发送数据包和确认数据包的结构。添加具体执行修改内容

ignite scaffold packet updatePost postID title content --ack postID --module blog


→ ignite scaffold packet updatePost postID title content --ack postID --module blog
Your saved project changes have not been committed.
To enable reverting to your current state, commit your saved changes.
Do you want to proceed without committing your saved changes: y

modify proto/planet/blog/packet.proto
modify proto/planet/blog/tx.proto
modify x/blog/client/cli/tx.go
create x/blog/client/cli/tx_update_post.go
create x/blog/keeper/msg_server_update_post.go
create x/blog/keeper/update_post.go
modify x/blog/module_ibc.go
modify x/blog/types/codec.go
modify x/blog/types/events_ibc.go
create x/blog/types/messages_update_post.go
create x/blog/types/messages_update_post_test.go
create x/blog/types/packet_update_post.go

🎉 Created a packet `updatePost`.

2. 在proto/blog/packet.proto目录下修改IbcPostPacketData，添加创建人string Creator=4，并重新编译proto文件。

执行编译器

→ ignite chain build
Cosmos SDK's version is: v0.46.6

🗃  Installed. Use with: planetd

3. 修改keeper方法中的OnRecvIbcPostPacket 。

id := k.AppendPost(
        ctx,
        types.Post{
            Creator: packet.SourcePort + "-" + packet.SourceChannel + "-" + data.Creator,
            Title:   data.Title,
            Content: data.Content,
        },
    )

    packetAck.PostID = strconv.FormatUint(id, 10)
