Question

我正在尝试在vcard中添加一个新字段，即“ Abc”。为此，我在xmpp_codec.spec文件中为此“ Abc”字段添加了xml。并在#vcard_temp中引用了它。我将在“ make spec”之后生成的xmpp_codec.erl，xmpp_codec.hrl，xep0054.erl文件放置在各自的目录中。

但是当我尝试通过发送此iq添加该字段的值时

<<"<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>">>

我收到此错误

[error] Hook vcard_iq_set crashed when running mod_avatar:vcard_iq_convert/1:

在320行的mod_avtar.erl中是此函数

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.

此函数内的第320行是case VCard#vcard_temp.photo of。

由于我没有更改#vcard_photo记录，所以我无法理解此错误，为什么它表示vcard_temp是错误记录？

编辑

这是添加XML并制定规范后生成的#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(),
                     logo :: 'undefined' | #vcard_logo{},
                     org :: 'undefined' | #vcard_org{},
                     categories = [] :: [binary()],
                     note :: 'undefined' | binary(),
                     prodid :: 'undefined' | binary(),
                     rev :: 'undefined' | binary(),
                     sort_string :: 'undefined' | binary(),

                     key :: 'undefined' | #vcard_key{},
                     desc :: 'undefined' | binary(),
                     abc :: 'undefined' | binary()}).
-type vcard_temp() :: #vcard_temp{}.

Answer 1

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

此外，值得检查一下旧的vcard_temp记录定义是否仍在某处使用。如果您将SQL存储用于mod_vcard，则可能不会，但是最好确保。

在ejabberd的vcard中添加字段时无法理解崩溃
