<b>AI摘要</b>
<p id="ai-output">这篇文章主要讲述了作者对一个学校的答题系统进行研究的经历。作者一开始利用网络考试中常见的将答案隐藏在源代码中的漏洞，在答题系统中找到了通过获取已知答案来作弊的方法，成功注册了花火学园，并因这个发现加入了运维团队。尽管作者随后指出系统的阅卷逻辑存在漏洞，可以通过无限重复已知答案的问题来获取满分，但问题并未被开发者完全修复。文章的最后提到，作者偶然间发现自己的修改并未解决问题，实际上漏洞仍然存在，被另一位测试者Sora Jin重新发现。作者反思认为，设计答题系统时应避免过于精密，以避免被轻易破解。</p>

</h1>
<p>在我维护的花火学园上，有一套答题系统。另外我能成为花火学园的运维也是因为这个系统，这件事也是个很神奇的事情。 </p><p>
具体内容也充满了机遇性，在我上高中的一天，我偶然发现了花火学园论坛，发现了之后我就想注册，然而这个论坛注册要求挺高，需要邀请码，如果没有就要去答20道题来获得邀请码。 </p><p>
那个题很难，正常人会的可能只有不到一半，如果有兴趣也可以看看<a href="https://www.say-huahuo.com/answer/">花火考场</a>，对于这些题同样我也不会。不过不会没关系，我以前在做网上的考试时，从来都不会安心看题，总会想着按下F12看看有没有什么不答题也能通过的方法。 </p><p>
按正常来说，应该没有人会把答案放到网页源代码中，但是在我做的好多次网络考试中，他们都把答案放到了源代码之中。我想这也许是为了降低服务器的运算压力吧……但是这样考试有点计算机知识的人都能把答案找出来，那考试还有啥意义…… </p><p>
总之就是因为这样奇怪的程序员很多，所以我每次在网上答题前都会按下F12看看有没有什么更简单的通过方法。 </p><p>
当时我看了看花火考场的源代码，是打包后的vue代码，看来是没法从网页源代码这里入手了，那第二点就是查看网络请求的数据了。 </p><p>
我大概看了一下，这个答题系统的获得题目和提交都是由同一个php程序工作的，过程是答题之前获得一组题目，答完后将答案和一组表示题目的ID组合到一起提交到这个程序上，提交后如果分数超过70分就会生成一个邀请码。看着这个过程，我突然脑洞大开，想着既然这个程序阅卷时只用ID和答案，那么我如果会做其中一道题，让这个程序反复批已知答案的同一道题，那么我就可以得满分了吧。 </p><p>
结果还真是这样，有点不可思议，于是我就成功的注册了花火学园。 </p><p>
注册后我就给管理员说了这个问题，也是这样的一次机会我加入了花火学园的程序组当中。 </p><p>
这个答题系统是由<a href="https://github.com/you06">you06</a>大佬开发的，不过我反馈了这个问题以后，貌似问题仍然没有被解决……而我一般看代码也是有一定的机遇，只有心情适合写代码或看代码的时候才愿意去写，所以我成为管理员以后我也没有解决。 </p><p>
关于答题系统这个东西我一直觉得开发起来很简单，像客观题就是比对一下答案是不是一致就行了，所以说我上了大学以后，我一直想着和同学一起做个答题系统练练手，可惜现代大学生最喜欢干的事情就是摸鱼，所以一直都没有做答题系统。 </p><p>
不过前几天正好我的心情符合看代码的状态，然后就看了看我能不能解决这个问题。</p>

<p>我闲来无事打开看了看阅卷的这个小程序，整个代码很短，也很好理解。当时加入程序组后我和you06说用session解决这个问题也许不错，虽然问题没解决，但是能看到他已经写了一部分了，也许是因为调试时出问题了，所以写了一半之后就再没管。 </p><p>
我看了看之所以you06的代码出了问题，其实主要原因是因为环境变量上少加了下划线，所以没读到数据才导致程序出问题的，既然问题找到了，我很轻松的就改了过来。</p>

<p>既然漏洞解决了，那我觉得即使大家看到程序的源代码也没关系，我检查了很多遍，也没看出问题，所以现在我将阅卷系统的核心代码展示出来：</p>

<p>其实答题系统想让用户钻不了空还是相当简单的事情，不过我个人还是希望那些答题系统能不要写的太精密，这样谁都不会胜利，互相为难也不好嘛……</p>

<p>我的愚蠢超乎我想象，这个代码的漏洞应该说完全没有解决，看似复杂的代码就如同破铜烂铁一般，轻易就能击碎QAQ。 </p><p>
我完全没有测试就胡乱改，改完之后除了让代码看起来更加复杂外没有解决任何问题。今天一位名叫<a href="https://github.com/MoeLoli">Sora Jin</a>的大佬像曾经的我一样测试了这个垃圾答题系统，重新发现了这个漏洞…… </p><p>
不过这次的修复不怎么美观，代码我就不放上来了，不是很难的问题，有兴趣的读者可以自己研究一下。</p></main>

<b>AI摘要</b>
<p id="ai-output">这篇文章讲述了作者经历了一次曲折的电脑购买过程，他原本期待AMD的Zen2架构CPU的电脑，最终选择了华硕天选，但遇到了预售难、发货延迟、配置缩水和价格问题。尽管更换了低端版且配置下降，但还是决定不再深究，期待这台5799元的电脑能在未来五年内正常运行。使用体验中，电脑存在屏幕闪动和噪音大的问题，但日常使用尚可。</p>

<p>在去年，我曾说过，以后如果有出了7nm制程、Zen2架构的AMD移动端CPU的电脑，我就买一台。结果今年年初AMD公司就出了。不过当时我听说当时出的时候好像是联想的电脑装的，名字好像叫Yoga Slim 7，可惜我等了好久也没见它开卖。正好这时我偶然看到了华硕天选也出了符合我要求的电脑，而且还有蓝色的外壳， <del>再加上看起来很像Kiana的天选姬23333，</del> 这看起来都很吸引我，于是我就决定买这款电脑了。</p>

</h1>
<p>当时我在这款电脑预售的第二天就知道了它的存在，思考了几天我决定买下它。当时这个电脑似乎只有在京东上可以买，但是由于某些原因我在淘宝上也看了看，结果淘宝上也有，能加内存条还不用抢，价格一样而且还比京东上多了一堆赠品。我想了想，新电脑有那么高级的配置应该多加一条内存，但是我手残，自己<a href="/2019/08/17/memory.html">装内存条还把笔记本装坏了</a>……再加上一堆加成，我就被这个淘宝店吸引了。 </p><p>
正是因为如此，所以我没有在第一次发售去抢，结果第一次发售结束后店家还没有发货，我试着抢第二次发售的货，结果由于第一批货口碑不错，第二批根本抢不到，再往后就开始涨价了……然而淘宝店的店家仍然没有发货……据他们说，厂家不给他们货了。 </p><p>
当然，这个店家拖这么久我是可以让他们给我赔钱的，但是我不希望赔钱，我想要电脑啊……直到前几天华硕又一次发售，这次他们在这个产品上加了一个低端版的电脑，没办法，店家好像有低端版本的，所以我就让他们给我换了一下。 </p><p>
换了低端版之后给我退了1K的差价，从原来6799的有着RTX2060显卡和16GiB内存的电脑妥协成了现在5799的只有GTX1650ti的垃圾显卡和8GiB的内存，配置一下降了一半，但是价格才退1000……而且还等了这么久QAQ……真的是太难了。</p>

<p>今天电脑到手了，还好是真的电脑，没给我寄一块砖头😂，打开看了一下也没什么太大的问题，于是我就开始把电脑原来家庭版的系统换成了专业版，我之所以换的主要原因是为了用BitLocker、Windows沙箱和Hyper-V。 </p><p>
整个调试好之后我发现这个电脑还是有不少问题的，比如在电脑没有打游戏的时候屏幕会闪，大概是核心显卡或者是驱动的问题？另外这个电脑在有一些运算的时候声音是真的大，真的和开直升机一样。不过平时上个网，打个字倒还是挺安静的，感觉风扇一点也没转，我现在写博客就用的是这台电脑。</p>

<p>不过既然这个电脑还不到6000，我觉得还是不追究这些问题了，至少这还是华硕的电脑，如果真的出了问题也有售后。现在我就希望未来5年内它能好好的为我工作，不要比过了20年都还能正常开机的电脑差就好了。</p></main>
