我正在尝试初始化两个libp2p.Host
实例之间的连接。为此,我需要获得一个peerstore.PeerInfo
。显而易见的方法是采用multiaddr.Multiaddr
返回的Host.Addrs
实例并将其传递给peerstore.InfoFromP2pAddr
。
简单,对吧?
有些代码可以做到这一点:
package main
import (
"github.com/SentimensRG/ctx"
"github.com/SentimensRG/ctx/sigctx"
libp2p "github.com/libp2p/go-libp2p"
pstore "github.com/libp2p/go-libp2p-peerstore"
)
var c = ctx.AsContext(sigctx.New())
func main() {
h0, err := libp2p.New(c)
if err != nil {
panic(err)
}
h1, err := libp2p.New(c)
if err != nil {
panic(err)
}
addr0 := h0.Addrs()[0]
peerinfo, _ := pstore.InfoFromP2pAddr(addr0) # type error here
}
以上代码将无法编译。编译器返回以下错误:
# command-line-arguments
01-basic-conn/main.go:25:39: cannot use addr0 (type "gx/ipfs/QmYmsdtJ3HsodkePE3eU3TsCaP2YvPZJ4LoXnNkDE5Tpt7/go-multiaddr".Multiaddr) as type "github.com/multiformats/go-multiaddr".Multiaddr in argument to "github.com/libp2p/go-libp2p-peerstore".InfoFromP2pAddr:
"gx/ipfs/QmYmsdtJ3HsodkePE3eU3TsCaP2YvPZJ4LoXnNkDE5Tpt7/go-multiaddr".Multiaddr does not implement "github.com/multiformats/go-multiaddr".Multiaddr (wrong type for Decapsulate method)
have Decapsulate("gx/ipfs/QmYmsdtJ3HsodkePE3eU3TsCaP2YvPZJ4LoXnNkDE5Tpt7/go-multiaddr".Multiaddr) "gx/ipfs/QmYmsdtJ3HsodkePE3eU3TsCaP2YvPZJ4LoXnNkDE5Tpt7/go-multiaddr".Multiaddr
want Decapsulate("github.com/multiformats/go-multiaddr".Multiaddr) "github.com/multiformats/go-multiaddr".Multiaddr
这似乎与gx
的路径管理有关,但我不确定如何。我与gx
的唯一互动是在recommended way中安装libp2p时,即从libp2p根目录运行make && make deps
,这在语义上等效于:
gx --verbose install --global
gx-go rewrite
有什么作用? 我必须做什么才能编译程序?
