miniprogram-ar-meet

实时视频会议小程序SDK

使用此组件需要依赖小程序基础库 2.2.1 以上版本，同时依赖开发者工具的 npm 构建。具体详情可查阅官方 npm 文档。

准备工作

• 注册微信小程序，登录微信公众号小程序平台获取微信小程序appid，appSecrert，修改类目审核（社交、教育、医疗、政务民生、金融，目前只有这些支持），并在开发设置中配置socket合法域名wss://域名：9095
• 获取开发者信息
• 开发-配置中开启“使用npm模块”，基础库选择2.4.0及以上，打开“不校验合法域名”、真机调试打开“调试”。集成miniprogram-ar-meet、miniprogram-ar-push、miniprogram-ar-play

使用说明

1.结合小程序会议SDK使用
2.结合小程序推流组件和小程序拉流组件使用

使用方法

• 安装 SDK

npm install --save miniprogram-ar-meet

• 会议初始化

//创建实例
let wxmeet = new wxRTMeet();
that.setData({
  wxmeet: wxmeet
});

//服务认证 方法一：
//wxmeet.initEngine(config.DEV_ID, config.APP_ID, config.APP_KEY, config.APP_TOKEN, config.APP_DOMAIN);

//服务认证 方法二：
//设置用户验证token
wxmeet.setUserToken("");
//配置开发者应用信息
wxmeet.initAppInfo(config.APP_ID, config.APP_TOKEN);

• 加入房间

//加入房间
wxmeet.joinRoom(roomId, userid, username, JSON.stringify({ userid }), that.data.enableVideo, that.data.enableAudio);
//加入房间成功回调
wxmeet.on("onJoinRoomOK", () => {
  wx.showToast({
    title: '加入房间成功',
  });
});
//加入房间失败回调
wxmeet.on("onJoinRoomFaild", (code, info) => {
  console.log("加入房间失败：", code, info ? info : "");
});

• 收到推流地址

//收到推流URL回调，将URL绑定到ar-push组件中，其他人将收到自己的视频
wxmeet.on("onGetPushUrl", (code, data) => {
  console.log('onGetPushUrl', code, data);
  if (code === 0) {//成功
    that.setData({
      pushURL: data.pushURL
    });
  } else {
    wx.showToast({
      icon: 'none',
      title: '获取房间签名失败',
    });
  }
});

• 退出房间

wxmeet.leaveRoom();
