What is the difference between the newly release ASP.NET WebHooks and Signal-R? What are the advantages or disadvantages? What are the use cases for each technology?

推荐答案

使用的的WebSockets SignalR是通知的ASP.NET应用程序中。您可以通过交换的WebSockets事件通知，但它需要持续的网络连接。

SignalR is for notification within an ASP.NET app using WebSockets. You can exchange event notifications through WebSockets, however it requires a constant network connection.

网络挂接是在其他Web应用程序和其他外部服务事件通知。 （想想B2B通信）。例如，你可以当有人向您钱，您的PayPal帐户收到网络挂接。贝宝POST请求触发了您predefined URL处理程序，然后你的应用程序如何处理该通知的东西。您$ P $第一p配置的PayPal方的一切。您还可以设置一个应用程序来处理传入POST请求。事件通报（近）的实时推给你。无需举行公开的网络连接，同时等待事件。

WebHooks are for event notification across other web applications and other external services. (Think B2B communication). For instance, you can receive a WebHook when someone sends you money to your PayPal account. PayPal fires off a POST request to your predefined URL handler and then your app does something with that notification. You pre-configure everything on the PayPal side first. You also set up an application to handle the incoming POST request. The event notification is "pushed" to you in (near) real-time. No need to hold open a network connection while waiting for events.

这两个可以互补。例如，当您收到来自PayPal网络挂接，可以通知登录的用户在你的webapp（使用SignalR /的WebSockets），钱已成功接收。

The two can be complementary. For example, when you receive the WebHook from PayPal, you can notify a logged in user on your webapp (using SignalR/WebSockets) that money has been received successfully.

TLDR：在不同的Web应用程序事件通知

TLDR: Event notification across different web applications
