api - 如何向 Skype 聊天室发出 Jenkins 构建状态警报？

Question

我们公司使用 Skype 进行通信，我希望能够在 Jenkins 构建失败(以及恢复时)时向 Skype 聊天室发送警报。

我该怎么做？

Answer 1

我已经使用 Skype Public API 完成了此操作

我所做的是编写一个 Perl 脚本，它使用 SkypeAPI CPAN模块处理与Skype的通信。它有点笨重，因为该脚本需要在运行 Skype 的桌面上运行。我在自己的桌面上运行它，该桌面始终处于开启状态，但这确实意味着该机器人对于我们团队的其他成员来说似乎就是“我”。

最终结果非常棒 - 每当 jenkins 构建更改状态时，机器人都会向任何通过输入 *alert 注册了兴趣的 Skype 聊天发送消息。此外，任何开发人员都可以通过输入 *jenkins

查看并共享最新的构建状态

第 1 步 - 扩展 SkypeAPI 模块

现在，SkypeAPI 模块非常基本。它的listen()方法中有一个消息循环，用于检查来自Skype客户端的新事件，如果没有，则休眠一会儿。

我希望我的脚本能够挂接到这个循环中，以便我的机器人能够定期检查 Jenkins RSS 提要，因此在使用 ActiveState 包管理器安装 SkypeAPI.pm 后，我对它进行了以下修改:

我声明了新属性“idler”以及现有属性...

__PACKAGE__->mk_accessors(
  qw/api handler_list stop_listen idler/
);

我添加了一个方法来设置“idler”回调，模块将调用该回调而不是休眠

sub register_idler {
    my $self = shift;
    my $ref_sub = shift;
    $self->idler($ref_sub);
}

最后我修改了消息循环以调用空闲程序(如果已设置)

sub listen {
    my $self = shift;

    my $idler=$self->idler();

    $self->stop_listen(0);
    while (!$self->stop_listen) {
        my $message;
        {
            lock @message_list;
            $message = shift @message_list;
        }
        if (not defined $message) {
            if ($idler)
            {
                $self->idler->($self);
            }
            else
            {
                sleep 0.1;             
            }
            next;
        }
        for my $id (sort keys %{$self->handler_list}) {
            $self->handler_list->{$id}->($self, $message);
        }
    }
}

第 2 步 - 编写机器人脚本

现在该模块的功能更强了，只需编写一个脚本来充当机器人即可。这是我的 - 我对原始版本进行了一些编辑，因为它包含其他不相关的功能，但它应该为您提供一个起点。

所有依赖模块都可以使用 ActiveState 包管理器安装。

第 3 步 - 运行机器人

如果您已将其另存为 robots.pl，只需打开一个控制台窗口，perl robots.pl 就可以运行它。 Skype 会询问您是否允许 perl.exe 与其通信，一旦您确认，就可以开始了!

进入团队聊天室并输入 *jenkins 以获取最新构建的摘要，并使用 *alert 注册房间以获取构建更改警报

完美:)
