我已经开始将 vLine API 集成到我的应用程序中，但是遇到了一个问题，recv:im即我发送的每条消息都会发出两次事件。
这是我在模板端发送聊天消息的代码：
$('#chat_room_input').bind('keypress', function(e) {
if(e.keyCode==13){
console.log('we send the message here');
VlineObject.sendMessageToPerson_(remoteUserId);
}
});
这也是我的 js 应用程序文件内容：
VlineApp = function(serviceId, current_user, ui_local_widgets, people) {
this.ui_local_widgets_ = ui_local_widgets;
this.serviceId_ = serviceId;
this.current_user_ = current_user;
this.profile_ = current_user.profile;
this.auth_token_ = current_user.auth_token;
this.people_ = people;
// the only required option is your serviceId
this.client_ = vline.Client.create({ serviceId: this.serviceId, "ui": true, "uiOutgoingDialog":true, "uiIncomingDialog":true, "uiBigGreenArrow":true, "uiVideoPanel": this.ui_local_widgets_.videopanel });
this.client_.on('login', this.onLoginUpdatePresence_, this);
// window.PROFILE and window.AUTH_TOKEN are generated by your application server
// and set in a script tag in your HTML document
this.client_.login(this.serviceId_, this.profile_, this.auth_token_)
.done(this.init_, this);
}
VlineApp.prototype.init_ = function(session) {
console.log('here in init ');
//console.log(this.people_);
this.session_ = session;
this.client_.on('recv:im', this.onMessage_, this);
}
VlineApp.prototype.updatePresence = function(e){
//FUNCTION CALL WHEN THE EVENT IS FIRED
var person = e.target;
var presenceState = person.getPresenceState();
var shortId = person.getShortId();
this.updatePresenceUI(shortId, presenceState);
}
VlineApp.prototype.updatePresenceUI = function(personid, presenceState) {
//UPDATE UI PRESENCE STATUS
$('#'+personid+'_status').html(presenceState);
/*
// Show/hide the call link based on presence
elem = document.getElementById('call-' + shortId);
if (presenceState === "online" && shortId !== currentUserid) {
elem.style.display = "";
} else {
elem.style.display = "none";
}
*/
}
VlineApp.prototype.updatePresenceAll = function(person){
//UPDATE PRESENCE STATUS FOR THE CURRENT PERSON AND ADD TRIGGER EVENT
this.updatePresence({target: person});
person.on('change:presenceState', this.updatePresence, this);
}
VlineApp.prototype.onLoginUpdatePresence_ = function(event){
this.session_ = event.target;
for (var i=0; i < this.people_.length; i++)
{
this.session_.getPerson(this.people_[i])
.done(this.updatePresenceAll, this);
}
}
VlineApp.prototype.showAlertUI = function(sender_name, sender_thumb, message_body) {
//here we should have push message to the chatroom
$('#'+this.ui_local_widgets_.chat_room_messages).append('<div>'+sender_name+' :'+message_body+'</div>');
}
VlineApp.prototype.onMessage_ = function(event) {
console.log('aici in on message');
var msg = event.message, sender = msg.getSender();
this.showAlertUI(sender.getDisplayName(), sender.getThumbnailUrl(), msg.getBody());
};
VlineApp.prototype.sendMessageToPersonObj = function(person)
{
var message = $('#'+this.ui_local_widgets_.chat_room_input).val();
$('#'+this.ui_local_widgets_.chat_room_input).val('');
//$('#'+this.ui_local_widgets_.chat_room_messages).append('<div>You :'+message+'</div>');
this.showAlertUI('You', '', message);
person.postMessage(message);
}
VlineApp.prototype.sendMessageToPerson_ = function(personid) {
if (this.session_)
{
this.session_.getPerson(personid)
.done(this.sendMessageToPersonObj, this);
}
}
VlineApp.prototype.getMessagesHistoryObj = function(person){
var messages_history = person.getMessages();
console.log('messages_history');
console.log(messages_history);
}
VlineApp.prototype.getMessagesHistory_ = function(personid) {
console.log(personid);
console.log(this.session_);
if (this.session_)
{
this.session_.getPerson(personid)
.done(this.getMessagesHistoryObj, this);
}
}
VlineApp.prototype.callPersonObj = function(person) {
person.startMedia();
}
VlineApp.prototype.callPerson_ = function(personid) {
if (this.session_)
{
this.session_.getPerson(personid)
.done(this.callPersonObj, this);
}
}
我必须指定聊天对话是在 2 个不同的用户之间使用 2 个来自 Vline 的不同令牌进行的。
有什么建议么？
