WebRTC：OperationError：未知的碎片（...）

时间：2020-04-18 16:57:49

标签： ajax firefox webrtc

开始之前：我必须将“ http; //”更改为“ http; //”（这不是我的代码中的错误）。 我正在尝试创建WebRTC视频和音频连接，并尝试使用ajax和数据库进行信号传输。但是我总是在控制台中获得以下信息：“ OperationError：未知ufrag（71c0b048）”

我是否在同一台计算机上进行操作（Firefox中的两个选项卡或私有模式下的选项卡，“正常”模式下的一个选项卡或同一连接上的两台不同的计算机或使用智能手机的一台计算机）都无所谓。 / p>

这是我的代码：

但是现在我遇到了候选人的另一个问题： “ OperationError：未知ufrag（71c0b048）”（似乎不知道用户片段）

...不久后： “ ICE失败，添加TURN服务器并查看about：webrtc了解更多详细信息”。 （我已经添加了STUN服务器...（在他告诉我要添加STUN服务器之前）

您知道那里发生了什么吗？我在互联网上进行了搜索，但我只能找到Firefox或Chrome错误跟踪系统中的固定错误。

在服务器端有一个mysql数据库，它将不同的json对象放入数据库中，并以“ get_offer”，“ get_answer”和“ get_candidate”等不同模式返回它。 （这似乎是可行的。它可以按原样保存不同的对象，并且似乎也可以很好地返回它。

我不确定这是否与我的代码有关，或者与我的互联网连接有关...

当我转到about：webrtc时，我会在会话统计信息中得到此信息：

我为这篇文章更改了一些IP和哈希，但希望不会以某种方式使其不再可读。

有人知道发生了什么吗？

最诚挚的问候，非常感谢您可以分享的任何提示。 Fuchur

“ uFrag”是“ usernameFragment”的缩写，它是ICE候选者的属性。来自w3 specification：

如果候选人。用户名片段不为null，并且不等于应用的远程描述的相应媒体描述中存在的任何用户名片段，请使用新创建的OperationError拒绝p并中止这些步骤。

我还没有自己做这件事，但是如果您正在寻找一种快速而肮脏的解决方案，那么从规格上看，您可以像这样将uFrag设置为null：

evt.candidate.usernameFragment = null;
peer_con.addIceCandidate( new RTCIceCandidate( evt.candidate ) );

答案 1 :(得分：0)

我有同样的错误信息。 我的错误是我试图将来自远程用户的ICE候选者添加到错误的对等连接中（即，我在错误的对等连接pc.addIceCandidate(theIceCandidate)上呼叫了pc）。
