WebRTC: OperationError: 未知ufrag(...)

问题描述 投票：0回答：1

在我们开始之前。我必须把 "http;/"改成 "http;/"(这不是我代码中的错误).我试图创建一个WebRTC视频&音频连接，并尝试使用ajax和数据库进行信号传输。但我总是在控制台得到这样的信息。"OperationError: Unknown ufrag (71c0b048)"

如果我在同一台电脑上这样做并不重要（Firefox中的两个标签或私人模式下的一个标签，一个在 "正常 "模式下，或在同一连接上的两台不同的电脑或使用我的智能手机的一个电热）。

这是我的代码。

但现在我遇到了另一个关于候选者的问题："OperationError: Unknown ufrag (71c0b048)" (似乎不知道用户片段)

...过了一小会儿："ICE失败，添加TURN服务器，详情请看about:webrtc"。(我已经添加了一个STUN服务器... ... (在他告诉我添加STUN服务器之前，我已经添加了一个STUN服务器)

你知道这是怎么回事吗？我在网上搜索了一下，但能找到的都是Firefox或Chrome的bug跟踪系统中的固定错误。

在服务器端有一个mysql数据库，它将把不同的json对象放入数据库，并以不同的模式返回，如 "get_offer"、"get_answer "和 "get_candidate"。(这似乎是工作。它像它应该的那样保存不同的对象，而且似乎也能很好地返回它。

我不完全确定这是否与我的代码有关，或者是否与我的网络连接有关。

当我进入about:webrtc时，我在会话统计中得到这样的信息。

我为了这个帖子改了几个IP和哈希值 但希望不要改到无法阅读的程度。

有人知道这是怎么回事吗？

问好，非常感谢您的任何提示。Fuchur

"uFrag "是 "usernameFragment "的缩写，它是ICE候选人的一个属性。从 w3规范:

如果 candidate.usernameFragment 不是空的，并且不等于任何存在于应用的远程描述的相应媒体描述中的用户名片段，用一个新创建的 OperationError 拒绝 p 并中止这些步骤。

我自己还没有这样做，但是如果你正在寻找一个快速和肮脏的解决方案，从规范来看，似乎你可以将uFrag设置为 null 像这样。

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

我也有同样的错误信息，我的错误在于我试图将远程用户的ICE候选者添加到错误的对等连接中（即，我调用了... ... pc.addIceCandidate(theIceCandidate) 在错误的对等连接上 pc).
