Asterisk 我无法从星号管理器界面获取事件

这是连接到Asterisk Manager界面的我的代码：

问题是，当我连接到服务器时，我收到“Asterisk Call Manager/1.1”消息。连接到服务器后，我登录到服务器，没有收到任何消息。我想从asterisk获取事件。使用网络套接字时是否存在问题？我是否应该使用特殊命令告诉星号我想要接收事件。

嗯。所以这不是AMI配置的问题

当连接完成时，您会启动一个BeginReceive，但一旦您收到一次数据，就不会启动一个新的BeginReceive

您需要在OnDataReceive中再次调用BeginReceive，以便它再次尝试从套接字读取

clientSocket.BeginReceive(data, 0, size, SocketFlags.None,
                          new AsyncCallback(OnDataReceive), clientSocket);

我在下面保留我的原始答案，因为这些信息仍然是你应该检查的。我将再次重申我的“仅供参考”——除非你是出于教育目的而这样做的，否则你真的应该使用现有的AMI库——特别是如果你不熟悉TCP的话

您发送的用户名和密码是什么？您确定已正确配置帐户以发送事件吗

一旦您通过登录通过Asterisk验证了您的连接，您应该开始自动接收事件。但是，请记住，您需要适当的读取授权类权限才能接收特定类型的事件。从sample manager.conf：

; Authorization for various classes
;
; Read authorization permits you to receive asynchronous events, in general.
; Write authorization permits you to send commands and get back responses.  The
; following classes exist:
;
; all       - All event classes below (including any we may have missed).
; system    - General information about the system and ability to run system
;             management commands, such as Shutdown, Restart, and Reload.
; call      - Information about channels and ability to set information in a
;             running channel.
; log       - Logging information.  Read-only. (Defined but not yet used.)
; verbose   - Verbose information.  Read-only. (Defined but not yet used.)
; agent     - Information about queues and agents and ability to add queue
;             members to a queue.
; user      - Permission to send and receive UserEvent.
; config    - Ability to read and write configuration files.
; command   - Permission to run CLI commands.  Write-only.
; dtmf      - Receive DTMF events.  Read-only.
; reporting - Ability to get information about the system.
; cdr       - Output of cdr_manager, if loaded.  Read-only.
; dialplan  - Receive NewExten and VarSet events.  Read-only.
; originate - Permission to originate new calls.  Write-only.
; agi       - Output AGI commands executed.  Input AGI command to execute.
; cc        - Call Completion events.  Read-only.
; aoc       - Permission to send Advice Of Charge messages and receive Advice
;           - Of Charge events.
; test      - Ability to read TestEvent notifications sent to the Asterisk Test
;             Suite.  Note that this is only enabled when the TEST_FRAMEWORK
;             compiler flag is defined.

所以，假设我想用密码“bar”作为用户“foo”进行身份验证，没有定义ACL，我想接收所有事件。我也只希望能够执行'system'和'call'类命令。我需要在manager.conf中将我的用户设置为：

[foo]
secret = bar
read = all
write = system,call

仅供参考-您可能正在重新发明车轮。除非你创建你自己的AMI库作为练习，否则你可能想考虑使用.< /P>谢谢Matt。事实上，我对TCP并不陌生。我不熟悉.NET套接字编程。
