在拨号计划中使用 GotoIf 时出错
我正在尝试实现一个需要与用户交互的复杂拨号计划。基于这种交互，拨号方案跳转到另一部分。下面给出了一些示例代码：
[test]
;This is a test.
exten => 0,n(qa1),NoOp()
exten => 0,1,Verbose(1, "This is a test")
exten => 0,n,Set(USER_ANSWER=0)
exten => 0,n,Read(USER_ANSWER,,1,,2,10)
exten => 0,n,Verbose(1, "User keyed in ${USER_ANSWER}")
exten => 0,n,GotoIf($[$["${USER_ANSWER}"="1"] | $["${USER_ANSWER}"="2"]]?eval1:qa1)
exten => 0,n,Verbose(1, "User keyed in ${USER_ANSWER}")
exten => 0,n(eval),NoOp()
...
运行上述代码时，星号在评估上述
GotoIf条件后挂起。错误信息如下：-- 用户输入“1” -- 在新堆栈中执行 [0@test:19] Verbose("DAHDI/13-1", "1, "User keyed in 1"") “用户输入1” -- 在新堆栈中执行 [0@test:20] GotoIf("DAHDI/13-1", "1?eval1:qa1") -- 转到（测试,0,21） -- 在新堆栈中执行 [0@test:21] NoOp("DAHDI/13-1", "") [Jan 25 10:47:48] WARNING[29738]: pbx.c:3677 pbx_extension_helper: No application 'If' for extension (test, 0, 22)
我的问题是：
- 该错误消息是什么意思？
- 我该如何纠正它才能正常工作？
I am trying to implement a complex dialplan that requires interaction with the user. Based on this interaction, the dialplan jumps to another part. Some sample code is given below:
[test]
;This is a test.
exten => 0,n(qa1),NoOp()
exten => 0,1,Verbose(1, "This is a test")
exten => 0,n,Set(USER_ANSWER=0)
exten => 0,n,Read(USER_ANSWER,,1,,2,10)
exten => 0,n,Verbose(1, "User keyed in ${USER_ANSWER}")
exten => 0,n,GotoIf($[$["${USER_ANSWER}"="1"] | $["${USER_ANSWER}"="2"]]?eval1:qa1)
exten => 0,n,Verbose(1, "User keyed in ${USER_ANSWER}")
exten => 0,n(eval),NoOp()
...
On running the above code, asterisk hangs up after evaluating the
GotoIfcondition above. The error messages are as follows:-- User entered '1'
-- Executing [0@test:19] Verbose("DAHDI/13-1", "1, "User keyed in 1"") in new stack
"User keyed in 1"
-- Executing [0@test:20] GotoIf("DAHDI/13-1", "1?eval1:qa1") in new stack
-- Goto (test,0,21)
-- Executing [0@test:21] NoOp("DAHDI/13-1", "") in new stack
[Jan 25 10:47:48] WARNING[29738]: pbx.c:3677 pbx_extension_helper: No application 'If' for extension (test, 0, 22)
My questions are:
- What does that error message mean?
- How can I correct it so it works?

GotoIf被正确调用。标签eval1后面有If语句。 Asterisk 没有If语句。将If语句替换为ExecIf就可以了。您可以通过在 Asterisk CLI 提示符下键入以下命令来找出可用的命令：核心显示应用程序<此处的命令名称>如果上述命令返回输出，则该命令可用，否则不可用。
The
GotoIfis invoked correctly. The labeleval1hasIfstatements following it. Asterisk does not haveIfstatements. Replacing theIfstatements withExecIfdid the trick. One can figure out what commands are available by typing, at the Asterisk CLI prompt, the following command:core show application <command name here>If the above command returns an output, then that command is available, else not.
