如何在Firechat中创建聊天室?

我正在使用Firechat,我可以成功启动聊天窗口。我正在使用Firebase custom authentication,我可以毫无问题地登录。但是,我现在尝试创建一个新的聊天室然后输入它。根据{{​​3}}我做了以下内容:

<!doctype html>
<html>
<head>
<title>Test</title>
<meta charset="UTF-8" />
<script src='https://cdn.firebase.com/js/client/2.0.2/firebase.js'></script>
<link rel='stylesheet' href='https://cdn.firebase.com/libs/firechat/2.0.1/firechat.min.css' />
<script src='https://cdn.firebase.com/libs/firechat/2.0.1/firechat.min.js'></script>
</head>
<body>

    <script type='text/javascript'>
    var fireBase = new Firebase("https://XXXXXXXXX.firebaseio.com/");

    function initChat(authData) {
      var Firechat = new FirechatUI(fireBase, document.getElementById('firechat'));
      Firechat.setUser(authData.uid, "Username");
      Firechat.createRoom("Test chat room", "public");
    }

    fireBase.authWithCustomToken("UNIQUE_TOKEN", function(error, authData) {
      if (error) {
        console.log("Login Failed!", error);
      } else {
        console.log("Login successful", authData);
        initChat(authData);
      }
    });
    </script>
    <div id='firechat'>
    </div>

</body>
</html>

在javascript控制台中,我可以看到登录成功:

Login successful Object { auth: Object, expires: XXXXXXXXX, token: "XXXXXXXX…", uid: "XXXXXX", provider: "custom" } 

但找不到createRoom函数:

TypeError: Firechat.createRoom is not a function

知道这里出了什么问题吗?

来自文档: Firechat.createRoom(roomName, roomType, callback(roomId))

创建一个具有给定名称(字符串)和类型(字符串 - 公共或私有)的新房间,并在完成时调用带有房间ID的回调。

看起来你没有回调。

 Firechat.prototype.createRoom = function(roomName, roomType, callback) {
    var self = this,
        newRoomRef = this._roomRef.push();

    var newRoom = {
      id: newRoomRef.name(),
      name: roomName,
      type: roomType || 'public',
      createdByUserId: this._userId,
      createdAt: Firebase.ServerValue.TIMESTAMP
    };

    if (roomType === 'private') {
      newRoom.authorizedUsers = {};
      newRoom.authorizedUsers[this._userId] = true;
    }

    newRoomRef.set(newRoom, function(error) {
      if (!error) {
        self.enterRoom(newRoomRef.name());
      }
      if (callback) {
        callback(newRoomRef.name());
      }
    });
  };

事实证明,Firechat javascript插件中有两个类(是正确的单词):

var chat = new FirechatUI
var chat = new Firechat

因为它们看起来很相似,所以我没有注意到它们之间的区别。在文档中没有任何地方我能够找到FirechatUI实例的详细信息(即使在github readme上建议使用此代码)。

无论如何,问题是new FirechatUI加载了聊天的实际用户界面。 new Firechat加载API,允许您与聊天插件对话(但到UI)。这是一个重要的区别。找到的文档here仅与API相关,因此如果您启动new Firechat实例。然而,诀窍是让UI启动并运行,然后直接与它交互(做一些事情,比如创建新房间或进入房间)。我老实说没有找到如何以官方/推荐方式这样做。我唯一能想到的就是黑客攻击。这很难看,但它确实有效。下面的代码包括创建新聊天室(使用Firechat)以及在UI中打开特定聊天室的功能(该位被黑客攻击,因为我无法找到直接与UI交互的方式)

FirechatUI对象与Firechat对象是分开的。 FirechatUI没有与Firechat相同的方法。

为了从FirechatUI对象获取关联的Firechat对象,您可以执行以下操作:

let chatUI = new FirechatUI(chatRef, document.getElementById("firechat-wrapper"));
let chat = chatUI._chat;

然后,您可以毫无问题地执行任何正常的Firechat操作。

chat.setUser(user.uid, firstName, function(user) {
    chat.resumeSession();
});

请记住,_chat元素并不应该被使用(正如你可以从命名约定中看出来的那样),但是由于FirechatUI没有正确地暴露出足够的功能,这可能是最干净的方法。
