CTFd 题目及平台容器日志监控

IShirai_KurokoI

首先就是后台对应api的实现,直接用Whale插件处理好的dockerclient方便写代码,新增后端api如下

@page_blueprint.route("/admin/getLog")
@admins_only
def admin_get_log():
id = request.args.get("id")
tail = request.args.get("tail", 1000)
docker_client = DockerUtils.client
if id:
try:
container = docker_client.containers.get(id)
logs_text = container.logs(stdout=True, stderr=True, stream=False, tail=tail)
return {
'success': True,
'message': logs_text.decode('utf-8')
}, 200
except e:
return {
'success': False,
'message': '日志获取失败:<br>' + str(e.__cause__)
}, 200
return {
'success': False,
'message': '日志获取失败'
}, 200

@page_blueprint.route("/admin/docker")
@admins_only
def admin_list_docker():
containers = DockerUtils.client.containers.list(all=True)
return render_template("whale_docker.html",
plugin_name=plugin_name,
containers=containers)

@page_blueprint.route("/admin/viewLog")
@admins_only
def admin_view_log():
return render_template("whale_log.html",
plugin_name=plugin_name)

然后就是前端实现上

const $ = CTFd.lib.$;

function language(en,zh) {
const cookies = document.cookie.split('; ');
for (const cookie of cookies) {
const [cookieName, cookieValue] = cookie.split('=');
if (cookieName === "Scr1wCTFdLanguage") {
return (decodeURIComponent(cookieValue) === "en" ? en : zh);
}
}
return zh;
}

function htmlentities(str) {
return String(str).replace(/&/g, '&amp;').replace(/</g, '&lt;').replace(/>/g, '&gt;').replace(/"/g, '&quot;');
}

function copyToClipboard(event, str) {
// Select element
const el = document.createElement('textarea');
el.value = str;
el.setAttribute('readonly', '');
el.style.position = 'absolute';
el.style.left = '-9999px';
document.body.appendChild(el);
el.select();
document.execCommand('copy');
document.body.removeChild(el);

$(event.target).tooltip({
title: language("Copied!","复制完成!"),
trigger: "manual"
});
$(event.target).tooltip("show");

setTimeout(function () {
$(event.target).tooltip("hide");
}, 1500);
}

$(".click-copy").click(function (e) {
copyToClipboard(e, $(this).data("copy"));
})

$(".view-log").click(function (e) {
e.preventDefault();
let container_id = $(this).attr("container-id");
window.open("/plugins/ctfd-whale/admin/viewLog?id="+container_id,"_blank")
});

然后就是查看日志的页面,为了看起来好看用xterm.js渲染日志,并且允许关闭自动刷新和设置日志显示行数

bundle的源码就是上面注释里的内容,引入xterm和xterm-fit-addon使用webpack打包。

效果如下:

完活下机!
