Quickblox JS SDK notifyOccupants 创建对话框

Question

我使用此代码从http://quickblox.com/developers/Javascript 检索。

我的 SDK 信息：/* QuickBlox JavaScript SDK - v2.1.4 - 2016-07-19 */

function notifyOccupants(dialogOccupants, newDialogId) {
  dialogOccupants.forEach(function(itemOccupanId, i, arr) {
    if (itemOccupanId != currentUser.id) {
      var msg = {
        type: 'chat',
        extension: {
          notification_type: 1,
          _id: newDialogId,
        }, 
      };
      QB.chat.send(itemOccupanId, msg);
    }
  });
}

当我执行这个函数时，它总是返回：

"quickblox.min.js:7 Uncaught TypeError: Cannot read property 'send' of undefined".

有人可以帮忙吗？

Answer 1

正如他们的tutorial 所说， 您必须先初始化 QB 对象才能使用它。

确保您的代码中有以下行：

QB.createSession({login: user.login, password: user.pass}, function(err, res) {
  if (res) {
    QB.chat.connect({userId: user.id, password: user.pass}, function(err, roster) {

并检查您的代码是否在 connect 函数回调中， 确保您的代码仅在 QB 初始化后运行。

我的代码：

var usersIds = [];
usersIds.push(user);

var params = {
    type: 3,
    occupants_ids: usersIds
};

console.log("Creating a dialog with params: " + JSON.stringify(params));

QB.chat.dialog.create(params, function (err, createdDialog) {
    if (err) {
        console.log(err);
        errorCallback();
    } else {
        console.log("Dialog " + createdDialog._id + " created with users: " + usersIds);

        // save dialog to local storage
        var dialogId = createdDialog._id;
        QuickbloxConfig.dialogs[dialogId] = createdDialog;

        QuickbloxConfig.currentDialog = createdDialog;
//
//                    self.joinToNewDialogAndShow(createdDialog);

        self.notifyOccupants(createdDialog.occupants_ids, createdDialog._id, 1);

        //self.triggerDialog(createdDialog._id);

        successCallback();

    }
});

只有在我调用 self.notifyOccupants(createdDialog.occupants_ids, createdDialog._id, 1); 时才会失败
