在ejabberd的vcard中添加字段时无法理解崩溃

Question

我正试图在vcard中添加一个新字段作为"Abc"。为此，我在xmpp_codec.spec文件中为这个"Abc"字段添加了一个xml。并在#vcard_temp中引用了它。我将在"make-spec"之后生成的xmpp_codec.ell、xmpp_codec.hrl、xep0054.erl文件放在它们各自的目录中。

但是当我试图通过发送这个iq 来增加这个字段的值时

<<"<iq id='D2sPz-22' type='set'><vCard xmlns='vcard-temp'><N><GIVEN>byname</GIVEN></N><Abc>10</Abc><FN>byname </FN><NICKNAME>byname</NICKNAME></vCard></iq>">>

我收到这个错误

[error] Hook vcard_iq_set crashed when running mod_avatar:vcard_iq_convert/1:
** Reason = {error,{badrecord,vcard_temp},[{mod_avatar,convert_avatar,[{file,"src/mod_avatar.erl"},{line,320}],3},{mod_avatar,vcard_iq_convert,[{file,"src/mod_avatar.erl"},{line,110}],1},{ejabberd_hooks,safe_apply,[{file,"src/ejabberd_hooks.erl"},{line,380}],4},{ejabberd_hooks,run_fold1,[{file,"src/ejabberd_hooks.erl"},{line,364}],4},{mod_vcard,process_sm_iq,[{file,"src/mod_vcard.erl"},{line,210}],1},{gen_iq_handler,process_iq,[{file,"src/gen_iq_handler.erl"},{line,132}],3},{gen_iq_handler,process_iq,[{file,"src/gen_iq_handler.erl"},{line,111}],4},{ejabberd_sm,route,[{file,"src/ejabberd_sm.erl"},{line,143}],1}]}

在mod_avtar.erl中，围绕线320的是这个函数

convert_avatar(LUser, LServer, VCard) ->
case get_converting_rules(LServer) of
[] ->
pass;
Rules ->
case VCard#vcard_temp.photo of
#vcard_photo{binval = Data} when is_binary(Data) ->
convert_avatar(LUser, LServer, Data, Rules);
_ ->
pass
end
end.

第320行是该函数内的CCD_ 1。

我无法理解这个错误，因为我没有更改#vcard_photo记录，为什么它说vcard_temp是一个坏记录？

编辑

这是添加xml并制作规范后生成的#vcard_temp记录

-record(vcard_temp, {version :: 'undefined' | binary(),
fn :: 'undefined' | binary(),
n :: 'undefined' | #vcard_name{},
nickname :: 'undefined' | binary(),
photo :: 'undefined' | #vcard_photo{},
bday :: 'undefined' | binary(),
adr = [] :: [#vcard_adr{}],
label = [] :: [#vcard_label{}],
tel = [] :: [#vcard_tel{}],
email = [] :: [#vcard_email{}],
jabberid :: 'undefined' | binary(),
mailer :: 'undefined' | binary(),
tz :: 'undefined' | binary(),
geo :: 'undefined' | #vcard_geo{},
title :: 'undefined' | binary(),
role :: 'undefined' | binary(),

-type vcard_temp() :: #vcard_temp{}. 

Answer 1

如果您修改了一个重新定义记录的库(在本例中为vcard_temp记录(，您最好重新编译ejabberd，以确保所有代码都使用新的记录定义。

此外，值得检查的是，旧的vcard_temp记录定义是否仍在某个地方使用。如果您使用mod_vcard的SQL存储，可能不会，但最好确保。
