连接到实时流时出现“用户无法发布流”的错误

问题描述

我正在使用 agora SDK 与一位用户进行实时连接。我知道该用户何时上线，但无法连接。以下是代码参考：

function App() {
  const [joined,setJoined] = useState(false);
  const channelRef = useRef("");
  const remoteRef = useRef("");
  const leaveRef = useRef("");

  async function handleSubmit(e) {
    try {
      if (channelRef.current.value === "") {
        return console.log("Please Enter Channel Name");
      }

      setJoined(true);

      rtc.client = AgoraRTC.createClient({ mode: "live",codec: "vp8" })

      await rtc.client.join(
        options.appId,options.channel,options.token || null,options.uid || null,);

      // Create an audio track from the audio captured by a microphone
      rtc.localAudioTrack = await AgoraRTC.createMicrophoneAudioTrack();
      // Create a video track from the video captured by a camera
      rtc.localVideoTrack = await AgoraRTC.createCameravideoTrack();

      rtc.localVideoTrack.play("local-stream");

      rtc.client.on("user-published",async (user,mediaType) => {
        // Subscribe to a remote user
        await rtc.client.subscribe(user,mediaType);
        console.log("subscribe success");
        // console.log(user);

        if (mediaType === "video" || mediaType === "all") {
          // Get `RemoteVideoTrack` in the `user` object.
          const remoteVideoTrack = user.videoTrack;
          console.log(remoteVideoTrack);

          // Dynamically create a container in the form of a DIV element for playing the remote video track.
          const PlayerContainer = React.createElement("div",{
            id: user.uid,className: "stream",});
          ReactDOM.render(
            PlayerContainer,document.getElementById("remote-stream")
          );

          user.videoTrack.play(`${user.uid}`);
        }

        if (mediaType === "audio" || mediaType === "all") {
          // Get `RemoteAudioTrack` in the `user` object.
          const remoteAudioTrack = user.audioTrack;
          // Play the audio track. Do not need to pass any DOM element
          remoteAudioTrack.play();
        }
      });

      rtc.client.on("user-unpublished",(user) => {
        // Get the dynamically created DIV container
        const playerContainer = document.getElementById(user.uid);
        console.log(playerContainer);
      });

      // Publish the local audio and video tracks to the channel
      await rtc.client.publish([rtc.localAudioTrack,rtc.localVideoTrack]);

      console.log("publish success!");
    } catch (error) {
      console.error(error);
    }
  }

  async function handleLeave() {
    try {
      const localContainer = document.getElementById("local-stream");

      rtc.localAudioTrack.close();
      rtc.localVideoTrack.close();

      setJoined(false);
      localContainer.textContent = "";

      // Traverse all remote users
      rtc.client.remoteUsers.forEach((user) => {
        // Destroy the dynamically created DIV container
        const playerContainer = document.getElementById(user.uid);
        playerContainer && playerContainer.remove();
      });

      // Leave the channel
      await rtc.client.leave();
    } catch (err) {
      console.error(err);
    }
  }

  return (
    <>
      <div className="container">
        <input
          type="submit"
          value="Join"
          onClick={handleSubmit}
          disabled={joined ? true : false}
        />
        <input
          type="button"
          ref={leaveRef}
          value="Leave"
          onClick={handleLeave}
          disabled={joined ? false : true}
        />
      </div>
      {joined ? (
        <>
          <div id="local-stream" className="stream local-stream"></div>
          <div
            id="remote-stream"
            ref={remoteRef}
            className="stream remote-stream"
          ></div>
        </>
      ) : null}
    </>
  );
}

export default App;

我可以连接，但是它显示了我这边的视频，这是意料之外的。我应该看到另一边的视频直播。那么需要进行哪些代码更改才能启用实时会话？

以下是错误图片

解决方法

直播时需要分配不同的客户端角色。 请参阅 this 以供参考

您需要通过

将其初始化为“host”

rtc.client = AgoraRTC.createClient({ mode: "live",codec: "vp8" })

rtc.client.setClientRole("host")

await rtc.client.join(
  options.appId,options.channel,options.token || null,options.uid || null,);

HTH！
