javascript - React-Native 上的 RTCPeerConnection 配置

Question

我尝试在 React-Native 上使用 WebRTC API 连接 2 个设备。所有设备都连接在同一个本地网络上，所以我不需要使用 ICE Server。

从网络到应用程序，报价生成的工作和设备之间的连接是completed.

但是，使用相同的代码，在应用程序上生成的报价react-native-webrtc更大，并且在发送 sdp 时连接不起作用。

在浏览器和工作上创建的示例报价：

{"type":"offer","sdp":"v=0\r\no=- 2622406983783727652 2 IN IP4 127.0.0.1\r\ns=-\r\nt=0 0\r\na=group:BUNDLE data\r\na=msid-semantic: WMS\r\nm=application 34771 DTLS/SCTP 5000\r\nc=IN IP4 192.168.10.21\r\na=candidate:3031968640 1 udp 2113937151 192.168.10.21 34771 typ host generation 0 network-cost 999\r\na=ice-ufrag:JWgO\r\na=ice-pwd:bAjL9i5KAlbQLpJH1mgfb2LR\r\na=ice-options:trickle\r\na=fingerprint:sha-256 1C:DA:20:FC:DB:4E:5A:7C:2F:63:29:FA:CF:61:22:5F:5B:DA:61:B0:78:1A:C4:FB:48:3B:A2:CB:56:8F:99:8F\r\na=setup:actpass\r\na=mid:data\r\na=sctpmap:5000 webrtc-datachannel 1024\r\n"}

并且报价生成react-native-webrtc，不工作：

在最新的报价中，我看到很多 URL，也许 RTCPeerConnection 上的配置参数不起作用？

const configuration = { iceServers: [{ urls: [] }] };
const pc = new RTCPeerConnection(configuration);

任何人都可以帮助我吗？
