<p>即时通讯(Instant messaging,简称 IM)通常是指互联网上用以进行实时通讯的系统,允许两人或多人使用网络即时的传递文字信息、文档、语音与视频交流。</p>
|
|
|
<p>即时通讯不同于 E-mail 在于它的交谈是实时的。大部分的即时通讯服务提供了状态信息的特性 ── 显示联络人名单,联络人是否在线上与能否与联络人交谈。</p>
|
|
|
<p>在互联网上目前使用较广的即时通讯服务包括 Windows Live Messenger、AOL Instant Messenger、Skype、Yahoo! Messenger、NET Messenger Service、Jabber、ICQ 与 QQ 等。</p>

|
|
|
<p>即时通讯应用场景非常广泛,需要实时交互消息的都需要。如:</p>
|
|
|
<ul>
|
|
|
<li>聊天工具:QQ、WeChat、在线客服等</li>
|
|
|
<li>手游网游:王者荣耀、魔兽等</li>
|
|
|
<li>网络直播:腾讯课堂、抖音直播等</li>
|
|
|
<li>订单推送:美团、餐饮下单系统等</li>
|
|
|
<li>协同办公:公司内部文件分享、工作安排、在线会议等。</li>
|
|
|
</ul>
|
|
|
<p>以上只是列举了比较常用的应用场景,但即时通讯的作用远不止于此。</p>

|
|
|
<p>即时通讯技术实现是复杂且过于底层化,所以微软为了简化即时通讯应用程序,开发出了一个强大且简易使用的通信库:<code>SignalR</code>,通过该库我们可以轻松实现类似 QQ、微信这类 IM 聊天工具,也能快速实现消息推送、订单推送这样的系统。</p>

<p>ASP.NET Core SignalR 是一种开放源代码库,可简化将实时 web 功能添加到应用程序的功能。 实时 web 功能使服务器端代码可以立即将内容推送到客户端。</p>
|
|
|
<p>适用于 SignalR :</p>
|
|
|
<ul>
|
|
|
<li>需要从服务器进行高频率更新的应用。 示例包括游戏、社交网络、投票、拍卖、地图和 GPS 应用。</li>
|
|
|
<li>仪表板和监视应用。 示例包括公司仪表板、即时销售更新或旅行警报。</li>
|
|
|
<li>协作应用。 协作应用的示例包括白板应用和团队会议软件。</li>
|
|
|
<li>需要通知的应用。 社交网络、电子邮件、聊天、游戏、旅行警报和很多其他应用都需使用通知。</li>
|
|
|
</ul>
|
|
|
<p>目前 <code>SignalR</code> 已经内置在 <code>.NET 5 SDK</code> 中。同时 <code>SignalR</code> 支持 <code>Web、App、Console、Desktop</code> 等多个应用平台。</p>

<p>在 <code>Furion</code> 框架中,任何服务功能都需要先注册后再使用,<code>SignalR</code> 也不例外。只需要在 <code>Startup.cs</code> 中添加注册即可:</p>

<p><code>SignalR</code> 包含两种用于在客户端和服务器之间进行通信的模型:<code>持久性连接</code>和 <code>集线器</code> 中心。</p>

<p>连接表示用于发送单接收方、分组或广播消息的简单终结点。 <code>持久性连接</code> (在 .NET 代码中由 PersistentConnection 类表示,在 ASP.NET Core SignalR 中 ,PersistentConnection 类已被删除。) 使开发人员能够直接访问 <code>SignalR</code> 公开的低级别通信协议。 使用基于连接的 Api (如 Windows Communication Foundation)的开发人员将对使用连接通信模型非常熟悉。</p>

|
|
|
<p>集线器是一种基于连接 API 构建的更高级别管道,<strong>它允许客户端和服务器直接调用方法</strong>。 <code>SignalR</code> 就像魔术一样处理跨机器边界的调度,使客户端能够像本地方法一样轻松地调用服务器上的方法,反之亦然。 如果开发人员已使用远程调用 (如 .NET 远程处理),则将对使用中心通信模型非常熟悉。 使用集线器还可以将强类型参数传递给方法,从而启用模型绑定。</p>
