WebRTC ICE 与有效 ICE 服务器和候选者的连接失败
[英]WebRTC ICE Connection Failing with Valid ICE Servers and Candidates
问题描述
This is a continuation of my previous question here .
这是我之前的问题的延续。
I started using the webrtc crate in this library to create a WebRTC connection, but I'm having issues with the ICE connection failing.我开始在这个库中使用webrtc板条箱来创建 WebRTC 连接，但是我遇到了 ICE 连接失败的问题。 I checked the STUN and TURN servers being used with this site and they all work correctly.我检查了该站点使用的 STUN 和 TURN 服务器，它们都可以正常工作。
Here is my current code:这是我当前的代码：
async fn new(...) {
let webrtcredux = Arc::new(AsyncMutex::new(WebRtcRedux::default()));
webrtcredux.lock().await.set_tokio_runtime(Handle::current());
let servers = ice.urls.into_iter().map(|url| {
if url.starts_with("turn") {
RTCIceServer {
urls: vec![url],
username: ice.username.clone(),
credential: ice.credential.clone(),
.. RTCIceServer::default()
}
} else {
RTCIceServer {
urls: vec![url],
.. RTCIceServer::default()
}
}
}).collect::<Vec<_>>();

After setting the remote answer SDP the ICE connection state changes to "checking", but after about 20 seconds it changes to "failing" and kills the connection.设置远程应答 SDP 后，ICE 连接 state 变为“检查”，但大约 20 秒后变为“失败”并终止连接。 Is there something wrong I'm doing in terms of the SDPs or my code?我在 SDP 或我的代码方面做错了什么？
Edit: I got logging working, here is the connection log: https://pastebin.com/vNvd3Af6编辑：我开始记录工作，这里是连接日志： https://pastebin.com/vNvd3Af6
Edit 2: I'm not receiving any inbound traffic from the STUN servers.编辑 2：我没有收到来自 STUN 服务器的任何入站流量。 Other programs using the same ICE servers work fine, so what could I be doing wrong outside of basic network configuration?使用相同 ICE 服务器的其他程序运行良好，那么在基本网络配置之外我会做错什么？
Edit 3: Here is a working ICE connection capture and here is the one I'm currently dealing with.编辑 3： 这是一个有效的 ICE 连接捕获， 这是我目前正在处理的一个。
Edit 4: I ran netstat to see what ports my code is listening on, and there are some differences.编辑 4：我运行netstat以查看我的代码正在侦听哪些端口，并且存在一些差异。 I cut out all other programs.我删掉了所有其他程序。
Here is the working ICE connection:这是工作的 ICE 连接：

The server I was communicating with only accepted LF line endings, while I was sending CRLF in my new implementation.我正在与之通信的服务器仅接受 LF 行结尾，而我在新实现中发送 CRLF。 Changing it to LF fixed the issue.将其更改为 LF 解决了该问题。
