【问题描述】：

我正在尝试使用 agora 发起视频通话，并在控制台上抛出以下错误，当我尝试加入通话时会发生这种情况。

code: "CAN_NOT_GET_GATEWAY_SERVER"
data: {retry: false}
message: "AgoraRTCError CAN_NOT_GET_GATEWAY_SERVER: dynamic use static key"
name: "AgoraRTCException"

我在这里附加了 react JS 代码我正在使用 Agora 的 react js 模块，并遵循了文档，我已经验证了电子邮件并创建了正确的 APP，它与 Agora 的 web 演示一起工作，但不是在这里。请帮忙

import React, { useEffect, useState, useRef } from "react";
import ReactDOM from "react-dom";
import "./App.css";
import { options, rtc } from "./constants";
import AgoraRTC from "agora-rtc-sdk-ng";

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

      setJoined(true);

      rtc.client = AgoraRTC.createClient({ mode: "rtc", codec: "h264" });
      const uid = await rtc.client.join(
        options.appId,
        channelRef.current.value,
        options.token,
        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);
        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",

        }

          const remoteAudioTrack = user.audioTrack;
          // Play the audio track. Do not need to pass any DOM element
          remoteAudioTrack.play();
        }

        playerContainer.remove();

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

      console.log("publish success!");

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

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

        const playerContainer = document.getElementById(user.uid);
        playerContainer && playerContainer.remove();
      });

      // Leave the channel
      await rtc.client.leave();

  }
  const [joined, setJoined] = useState(false);

【解决方案1】：

由于令牌过期，您需要在选项对象中再次设置令牌和频道名称。您可以从https://console.agora.io/project/ 生成新令牌

【讨论】：

【解决方案2】：

奇怪的是，示例相关文档说令牌是可选的，但实际上它是必需的。添加它并解决问题

【讨论】：

【解决方案3】：

此问题的另一个可能原因是用于生成令牌的 uid 与用于加入频道的 uid 不匹配。因此，请确保令牌相同。

【讨论】：

【解决方案4】：

如果您使用 agora sdk 并且发生这种情况，您必须尝试这些

启用项目的实时模式

启用辅助证书并使用它

最后也是最重要的，如果您遇到令牌无效或身份验证失败错误，则将 0 放入 Uid 并生成 RtcTokenBuilder::buildTokenWithUid

这解决了我的问题，希望对你有帮助
