google 的 WebRTC 笔记之 ice 细节

技术2023-04-08 115

用webrtc做云游戏项目做了一年多了，最近有空，准备对webrtc做一些总结并输出一些东西。初期文档可能会比较简陋，后面会慢慢丰富。

这篇文章主要记录代码级别STUN 的细节，内容比较粗糙，仅供参考。

连接信令信令服务器后，解析stun server配置调用路径，解析好stun server uri，保存备用：

Conductor::OnPeerConnected

Conductor::ConnectToPeer

Conductor::InitializePeerConnection

Conductor::CreatePeerConnection PeerConnectionFactory::CreatePeerConnection

PeerConnection::Initialize

ParseIceServers

ParseIceServerUrl

然后收集通讯用“网络接口”--gathering

Conductor::OnSuccess

PeerConnection::SetLocalDescription

PeerConnection::DoSetLocalDescription

JsepTransportController::MaybeStartGathering

异步触发下一个调用

JsepTransportController::MaybeStartGathering

P2PTransportChannel::MaybeStartGathering

PortAllocator::CreateSession

BasicPortAllocator::CreateSessionInternal

BasicPortAllocatorSession::BasicPortAllocatorSession

BasicNetworkManager::StartUpdating

异步触发下一个调用

BasicNetworkManager::OnMessage rtc::BasicNetworkManager::UpdateNetworksContinually rtc::BasicNetworkManager::UpdateNetworksOnce cricket::BasicPortAllocatorSession::OnNetworksChanged cricket::BasicPortAllocatorSession::GetNetworks //枚举本地Ip, 过滤无效ip,如127.0.0.1

在拿到可用于通信用的 ip_port后，创建端口（含音频、视频），绑定并用其发送到stun server

AllocationSequence::OnMessage AllocationSequence::CreateUDPPorts BasicPortAllocatorSession::AddAllocatedPort UDPPort::PrepareAddress UDPPort::OnLocalAddressReady UDPPort::MaybePrepareStunCandidate UDPPort::SendStunBindingRequests UDPPort::SendStunBindingRequest StunRequestManager::Send StunRequestManager::SendDelayed

在拿到回复后，添加外网ip到 candidate集合，供后面发送给对端（peer)用

AllocationSequence::OnReadPacket UDPPort::OnReadPacket //这里会解析是不是stun消息 StunRequestManager::CheckResponse StunBindingRequest::OnResponse UDPPort::OnStunBindingRequestSucceeded Port::FinishAddingAddress BasicPortAllocatorSession::OnCandidateReady

以下是对前面几个异步调用的汇总：

P2PTransportChannel::MaybeStartGathering

PeerConnectionProxyWithInternal::SetLocalDescription

PeerConnection::SetLocalDescription

JsepTransportController::MaybeStartGathering

P2PTransportChannel::MaybeStartGathering

PortAllocator::CreateSession

BasicPortAllocatorSession::GetNetworks

BasicPortAllocatorSession::StartGettingPorts

BasicPortAllocatorSession::GetPortConfigurations异步调用

BasicPortAllocatorSession::DoAllocate

AllocationSequence::Start

AllocationSequence::CreateUDPPorts 异步

UDPPort::PrepareAddress

BasicPortAllocatorSession::AddAllocatedPort

UDPPort::OnLocalAddressReady

BasicPortAllocatorSession::OnCandidateReady

下面我截取了相关日志，对照上面的函数调用看
