我正在尝试在 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.erl、xmpp_codec.hrl、xep0054.erl文件放在它们各自的目录中。

但是当我尝试通过发送这个 iq 来添加这个字段的值时

<<"<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:

在 mod_avtar.erl 中的第 320 行是这个函数

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.

并且第 320 行在case VCard#vcard_temp.photo of这个函数里面。

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

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(),

                     adr = [] :: [#vcard_adr{}],
                     label = [] :: [#vcard_label{}],
                     tel = [] :: [#vcard_tel{}],
                     email = [] :: [#vcard_email{}],

                     abc :: 'undefined' | binary()}).
-type vcard_temp() :: #vcard_temp{}.

如果您修改了重新定义记录的库(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,值得检查旧的 vcard_temp 记录定义是否仍在某处使用。如果您为 mod_vcard 使用 SQL 存储,可能不会,但最好确保。
