优雅地终止 Erlang 服务器或 fsm？
我有一个具有 gen_fsm 行为的模块。 现在，我通过在适当的状态/消息中返回标准 {stop, Reason, State} 来终止它。
它似乎正确终止，但在运行时被认为是错误。
这是正常的吗？ 有没有办法停止 fsm 进程而不将其视为错误？
I have a module that has the behavior of gen_fsm. Right now I am terminating it by returning the standard {stop, Reason, State} in an appropriate state/message.
It seems to terminate correctly, but it's considered an error during runtime.
Is this normal? Is there a way to stop the fsm process without it being considered an error?

返回值是 {stop,Reason,StateData} 而不是 {stop,StateName,StateData}。
如果原因不是正常或关闭，则会生成错误报告。 对于服务器的正常退出，请使用正常，当服务器被其主管要求退出时，使用关闭。
（现在进行编辑，已添加错误详细信息。）
gen_fsm正在调用client_fsm:terminate(normal, displayed, {state,#Port<0.144>,12345,"Bob"})< /code>这会导致 function_clause 异常（该函数存在，但没有子句可以与这些参数匹配）。 如果您更改
client_fsm:terminate/3以使该调用成功，则错误应该消失。The return value is {stop,Reason,StateData} not {stop,StateName,StateData}.
An error report is generated if Reason is something other than normal or shutdown. For a normal exit of your server use normal, shutdown is used when the server is asked to exit by its supervisor.
(Edit now that error details have been added.)
gen_fsmis callingclient_fsm:terminate(normal, loggedin, {state,#Port<0.144>,12345,"Bob"})which is leading to a function_clause exception (the function exists but no clause can be matched against those arguments). If you change
client_fsm:terminate/3so that that call succeeds the error should go away.
