欢迎大家前往 腾讯云+社区 ，获取更多腾讯海量技术实践干货哦~ 本文由 前端林子 发表于 云+社区专栏 本文主要会介绍如何基于MessengerJS，实现iframe父窗体与子窗体间的通信，传递数据信息。同时本文会提供一个可运行的实例代码，实现在父窗体中，获取到来自子窗体的数据的效果。 (1)需要在当前的前端项目中，使用iframe嵌套别的站点页面。 (2)当子窗体触发了一个事件后，要给父窗体传一个跳转地址的url。父窗体监听到这个事件后，根据接收到的url，来更新当前父窗体的url，实现页面的跳转。 可以采用 MessengerJS 方案，该方案可以实现父窗体与iframe之间的通信、多个iframe之间的通信。不过要前提是要确保对不同域的页面有修改权限，并且父窗体、子窗体页面都要同时加载这个MessengerJS。 (1) 在需要通信的父窗体、和子窗体的文档中，都需要引入MessengerJS。 (2) 父窗体和子窗体各自的文档（document）中，都需要自己的Messenger与其他文档通信，父窗体和子窗体的window对象都对应着有且仅有一个Messenger对象，该Messenger对象会负责当前window的所有通信任务。因此， 每个Messenger对象都需要唯一的名字 ，这样它们之间才可以知道是在跟谁通信。另外，MessengerJS方案 推荐指定项目名称，

I'm currently trying to make a Messenger Bot with the Messenger Platform. I have a Facebook page, app, everything set up, it currently works when I (an admin for the app) message it. So, I made a few test users to test it with more users. But, whenever I login as a test user, I can't seem to message the page. As a test user, I can't access the page, and a direct Messenger link gives an "access denied" page. As an admin, I tried to add this test users as a "Tester" under the roles, but I also get more "access denied" messages. So, is there a way to use a Facebook Test User to interact with my

原文： https://www.cnblogs.com/wzh2010/p/6679025.html MVVM的目标之一就是为了解耦View和ViewModel。View负责视图展示，ViewModel负责业务逻辑处理，尽量保证 View.xaml.cs中的简洁，不包含复杂的业务逻辑代码。 但是在实际情况中是View和ViewModel之间的交互方式还是比较复杂的，View和ViewModel的分离并不是界定的那么清晰。 比如以下两种场景： 1、如果需要某张视图页面弹出对话框、弹出子窗体、处理界面元素，播放动画等。如果这些操作都放在ViewModel中，就会导致ViewModel还是要去处理View级别的元素，造成View和ViewModel的依赖。 最好的办法就是ViewModel通知View应该做什么，而View监听接收到命令，并去处理这些界面需要处理的事情。 2、ViewModel和ViewModel之间也需要通过消息传递来完成一些交互。 而MVVM Light 的 Messenger类，提供了解决了上述两个问题的能力: Messenger类用于应用程序的通信，接受者只能接受注册的消息类型，另外目标类型可以被指定，用Send<TMessage, TTarget>(TMessage message) 实现， 在这种情况下信息只能被传递如果接受者类型和目标参数类型匹配

I am eager to know about the architecture of different real-time messenger apps. Are they using any generic protocol/architecture? The WhatsApp Architecture Facebook Bought For $19 Billion explains the architecture involved in design of whatsapp. Here is the general explanation from the link WhatsApp server is almost completely implemented in Erlang. Server systems that do the backend message routing are done in Erlang. Great achievement is that the number of active users is managed with a really small server footprint. Team consensus is that it is largely because of Erlang. Interesting to

I have relatively simple Facebook Messenger bot in php for research purposes: $access_token = "xxxxxxx"; $challenge = $_REQUEST['hub_challenge']; $verify_token = $_REQUEST['hub_verify_token']; if ($verify_token === 'MY_VERIFICATION_TOKEN') { echo $challenge; } $input = json_decode(file_get_contents('php://input'), true); $sender = $input['entry'][0]['messaging'][0]['sender']['id']; $message = $input['entry'][0]['messaging'][0]['message']['text']; $url = 'https://graph.facebook.com/v2.6/me/messages?access_token='.$access_token.'; $ch = curl_init($url); if($message=="hi") { $jsonData = '{

I'm sending the user from the messenger chat to a payment page in my application. Messenger opens the page in a webview. Now I'd like to close the webview and send the user back to Messenger while also sending something to the webhook in order to notify it that the user has finished the payment page. What is the best way to accomplish this? You can only achieve this if the payment page is controlled(developed by you), if it is a third party payment gateway there is nothing you can do. if the payment page is controlled by you, you can pass the sender ID as a parameter via web_url or get the

I'm looking for a library to do requests to Viber messenger server. I need to: send messages to users; check sent messages delivery status; check that a user has Viber account. I know that Viber has no open API for developers, but maybe someone has experience with reverse engeneering of Viber protocol or some else methods of communication with Viber. Or if someone can do it, please, write me, I have a suggestion for you. All I did was createing an applicaion for UIautomate of viber message sending using viber desktop application. if you want to send bulk messages or messages to your contact do

I'm trying to implement the new Facebook Checkbox plugin in a form but in a weird way I can't get it showing on the screen. So I don't get errors clientside but Iframe is hidden. Here's an simplified example of the code: <html> <head> <script> window.fbAsyncInit = function() { FB.init({ appId : '1815704925309469', xfbml : true, version : 'v2.6' }); FB.Event.subscribe('messenger_checkbox', function(e) { console.log("messenger_checkbox event"); console.log(e); if (e.event == 'rendered') { console.log("Plugin was rendered"); } else if (e.event == 'checkbox') { var checkboxState = e.state; console
