rust-examples

这是一个 libp2p 的rust 使用例子，原始代码几乎来自

rust-libp2p/examples 教程网址 http://www.libp2p.net.cn

git clone https://github.com/libp2p-examples/rust-examples
cd rust-examples
cargo build --example chat

编译第一个例子

cargo build --example 01-peer

增加了自制协议 放在 src目录下的三个文件

src/
├── handler.rs
├── lib.rs
└── protocol.rs

本协议 仅仅支持 收发字符串，使用用例见 examples/03-msg.rs

cargo build --example 03-msg

开启两个 用例发送消息

./target/debug/examples/03-msg
Local peer id: PeerId("12D3KooWSp7toxzXPHZvpf3STUWVZaKxFYBKDj2An1UJj5CgddUC")
Listening on "/ip4/127.0.0.1/tcp/36387"
Listening on "/ip4/192.168.1.17/tcp/36387"

./target/debug/examples/03-msg /ip4/192.168.1.17/tcp/36387

这样就可以敲键盘互相发送消息了。

利用relay 穿透打洞

cargo build --example 05-relay
cargo build --example 06-hole_punching

启动relay server

#.\target\debug\examples\05_relay
opt: Opt { use_ipv6: None, secret_key_seed: 0, port: 45678 }
Local peer id: PeerId("12D3KooWDpJ7As7BWAwRMfu1VU2WCqNjvq387JEYKDBj4kx6nXTN")
Listening on "/ip4/192.168.1.105/tcp/45678"
Listening on "/ip4/127.0.0.1/tcp/45678"

启动客户端 B
