我正试图找到一种方法,根据用户加载订单来获取多个集线器或聊天室。您必须使用组:
您必须与团队合作:
您必须根据打开的订单id将用户分组,更改集线器并添加如下方法:
public class ChatHub: Hub {
public void Send(string name, string message,string orderId) {
// Call the addNewMessageToPage method to update clients.
Clients.Group(orderId).addNewMessageToPage(name, message);
}
public void JoinOrderGroup(string name,string orderId)
{
Groups.Add(Context.ConnectionId, orderId);
}
}
然后修改JavaScript,在用户打开页面时调用“JoinOrderGroup”
@section scripts {
<!--Script references. -->
<!--The jQuery library is required and is referenced by default in _Layout.cshtml. -->
<!--Reference the SignalR library. -->
<script src="~/Scripts/jquery.signalR-2.0.3.min.js"></script>
<!--Reference the autogenerated SignalR hub script. -->
<script src="~/signalr/hubs"></script>
<!--SignalR script to update the chat page and send messages.-->
<script>
$(function () {
// Reference the auto-generated proxy for the hub.
var orderId = '@Model.Id' //You can change this line to get the orderId from the correct place
var chat = $.connection.chatHub;
// Create a function that the hub can call back to display messages.
chat.client.addNewMessageToPage = function (name, message) {
// Add the message to the page.
$('#discussion').append(htmlEncode(name)
+ ':' + htmlEncode(message) + '\n');
};
// Get the user name and store it to prepend to messages.
//$('#displayname').val(prompt('Enter your name:', ''));
// Set initial focus to message input box.
$('#message').focus();
// Start the connection.
$.connection.hub.start().done(function () {
$('#sendmessage').click(function () {
// Call the Send method on the hub.
chat.server.send($('#displayname').val(), $('#message').val());
// Clear text box and reset focus for next comment.
$('#message').val('').focus();
chat.server.joinOrderGroup($('#displayname').val(),orderId);
});
});
});
// This optional function html-encodes messages for display in the page.
function htmlEncode(value) {
var encodedValue = $('<div />').text(value).html();
return encodedValue;
}
</script>
}
<script>
@节脚本{
$(函数(){
//为中心引用自动生成的代理。
var orderId='@Model.Id'//您可以更改此行以从正确的位置获取orderId
var chat=$.connection.chatHub;
//创建一个中心可以回调以显示消息的函数。
chat.client.addNewMessageToPage=函数(名称、消息){
//将消息添加到页面。
$(“#讨论”).append(htmlEncode(名称)
+“:”+htmlEncode(消息)+'\n');
};
//获取用户名并将其存储到消息前。
//$('#displayname').val(提示('输入您的姓名:','');
//将初始焦点设置为消息输入框。
$(“#消息”).focus();
//启动连接。
$.connection.hub.start().done(函数(){
$('#sendmessage')。单击(函数(){
//在集线器上调用Send方法。
chat.server.send($('#displayname').val(),$('#message').val());
//清除文本框并重置下一条注释的焦点。
$('#message').val('.focus();
chat.server.joinOrderGroup($('#displayname').val(),orderId);
});
});
});
//此可选函数用于对页面中显示的消息进行html编码。
函数htmlEncode(值){
var encodedValue=$('').text(value.html();
返回编码值;
}
}
这样,当页面启动且集线器连接时,它将发送一条消息加入表单中与订单相关的组,并且对send message方法的所有后续调用都将包括订单id,并且它将仅以此顺序传播给用户。您必须根据打开的订单id将用户分组,更改中心并添加一个方法,如下所示:
public class ChatHub: Hub {
public void Send(string name, string message,string orderId) {
// Call the addNewMessageToPage method to update clients.
Clients.Group(orderId).addNewMessageToPage(name, message);
}
public void JoinOrderGroup(string name,string orderId)
{
Groups.Add(Context.ConnectionId, orderId);
}
}
然后修改JavaScript,在用户打开页面时调用“JoinOrderGroup”
