问题 "navigator.msLaunchUri" in IE Edge always return success , "noHandlerCallback" is not executed I tried this : navigator.msLaunchUri('App:123456', function() { alert('success'); }, function() { alert('failed'); } ); It will always return "success" and if the protocol was not supported it will open the windows store dialog and return "success" 回答1: I have seen that Edge behaves differently from IE11 in this regard. I am not sure if this exactly the same problem that you are experiencing but

问题 I got a struct : struct ErrorResultType: ErrorType { var description: String var code: Int } and a protocol: protocol XProtocol { func dealError(error: ErrorResultType) } Now I want to make an extention of UIViewController: extension UIViewController: XProtocol { func dealError(error: ErrorResultType) { // do something } } So I can subclass from this and override the function like: class ABCViewController: UIViewController { --->override func dealError(error: ErrorResultType) { super

问题 The Swift documentation says the following about protocols : You can check for protocol conformance only if your protocol is marked with the @objc attribute, as seen for the HasArea protocol above. This attribute indicates that the protocol should be exposed to Objective-C code and is described in Using Swift with Cocoa and Objective-C. Even if you are not interoperating with Objective-C, you need to mark your protocols with the @objc attribute if you want to be able to check for protocol

问题 What is the best way for flex frontend to communicate with backend writted in C#? The only communication channel in HTTP, so no custom sockets. I used SOAP in the past, but am concerned about performance since the large overhead of xml, and this application I'm currently working on will be pretty data intensive. Anything that supports easy setup and transparent marshaling/unmarshaling is OK. Is there something as BlazeDS for .net? 回答1: I found a few options by googling AMF .NET and AMF C#

问题 This is a generic C++ design question. I'm writing an application that uses a client/server model. Right now I'm writing the server-side. Many clients already exist (some written by myself, others by third parties). The problem is that these existing clients all use different protocol versions (there have been 2-3 protocol changes over the years). Since I'm re-writing the server, I thought it would be a great time to design my code such that I can handle many different protocol versions

问题 I'm used to using Objective-C protocols in my code; they're incredible for a lot of things. However, in C++ I'm not sure how to accomplish the same thing. Here's an example: Table view, which has a function setDelegate(Protocol *delegate) Delegate of class Class, but implementing the protocol 'Protocol' Delegate of class Class2, also implementing 'Protocol' setDelegate(objOfClass) and setDelegate(objOfClass2) are both valid In Obj-C this is simple enough, but I can't figure out how to do it

问题 I have a design decision to make. I need your advice. Requirements: A server and a client. client is typically a mobile phone. Connected through the Internet. Server and client want to talk to each other. Exchange of text, multimedia between the client and the server. Text would be some standard format. that is predecided. Real time requirements Session would typically last for 5-15 minutes. In some cases for under a minute. assume 5 minutes as the session duration. The protocol should adhere

问题 Closed . This question needs to be more focused. It is not currently accepting answers. Want to improve this question? Update the question so it focuses on one problem only by editing this post. Closed 4 years ago . I am eager to know about the architecture of different real-time messenger apps. Are they using any generic protocol/architecture? 回答1: The WhatsApp Architecture Facebook Bought For $19 Billion explains the architecture involved in design of whatsapp. Here is the general

问题 I've been working on a project recently that should connect to a server with the help of a protocol. So far so good, but when I combed to decrypt the packages, I quickly noticed that something is not working properly. The first 16 bytes of all packets are decrypted incorrectly. I have tried it with different libraries but that does not work either. I work in the C++ language and have so far used Crypto++ and OpenSSL for decryption, without success. Under this Link you can find the protocol,
