Python读取项目目录和子目录下的文件
我在functions文件夹下有个py，用来读取config目录里的配置文件，发现 ../config/config.json 报错文件不存在。
咨询了copilot之后，学习了需要用如下写法：
self.config_file = os.path.join(os.path.dirname(os.path.dirname(__file__)), 'config/config.json')
好麻烦。
Electron真的是我见过最令人头痛的软件
Electron
一步一个报错
垃圾软件。
我再用Electron我就是狗！

河南宗教知识竞赛加密算法分析（第二篇）
上回说到
请先看第一回：https://blog.zixutech.cn/archives/664
本回
由于官方2天更新了7次，尤其是今天更新了4次，我人直接裂开，官方没有采用我的强加密手段，而是继续乱jb加密，但是更新频次如此之快，我也懒得搞了，本篇文章主要是分享一下期间几次更新的加解密算法，别说还挺有创意的。
算法代码
我已添加了详细的注释供读者们阅读学习，对代码有疑问可以评论提出。
// 宗教答题第2~5次更新的加密函数
function encrypt(content) {
// content 是要加密的值，宗教里就是题号 如1000065
// 随机字符串 + # + 题号，拼接后进行base64编码
content = window.btoa('1688106372619ddf853ddce845744766#' + content)
// code是要穿插在上述content里的内容，其内容是用户ID(需经过base64解码)和csmpagerid(不知道这到底是啥)
let code = window.atob(memberusercode) + csmpagerid;
// 开始将code穿插进content进行混淆
for (let i = 0; i < code.length; i++) {
// 在1 3 5 7 9 ··· 索引位置逐位插入code的内容
content = content.slice(0, 2 * i + 1) + code.slice(i, i + 1) + content.slice(2 * i + 1);
}
// 因为content是经过base64编码的，所以其最后可能会出现=== == =这样的，如果有则替换为特定的字符串，这里是O0O0OO0O0O
// 如果没有，则直接在后面加上这个O0O0OO0O0O
if (content.indexOf('===') == -1 && content.indexOf('==') == -1 && content.indexOf('=') == -1) {
content += 'O0O0OO0O0O';
} else {
content = content.replace('===', 'O0O0OO0O0O');
content = content.replace('==', 'O0O0OO0O0O');
content = content.replace('=', 'O0O0OO0O0O');
}
// 加密完成，返回数据
// console.log(content)
return content;
}
// 宗教答题第2~5次更新的解密函数
function decrypt(content) {
// content 要解密的内容，一般是题号，解密前的样子大概是
// M1T0A000N6j0I844N3j2c1y4M1T9Y8x8O5W9R8j0N6W1I9xdOcG5Qbx1N8zcIc4dM4z1I045M3j4Q240N7T1IjMTAwMDAwOQO0O0OO0O0O
// 设计一个新的字符串用来当做解密后的字符串
let newStr = ''
// 逐位循环去除混淆
for (let i = 0; i < content.length; i++) {
// 42的意思是，用户ID的长度和csmpagerid的长度一共是42位，所以只需要去除42个字符即可
if (i >= 42) {
// 循环次数大于等于42后，直接不再裁剪，而是拼接最后所有字符串
newStr += content.slice(2 * i)
break
}
// 裁剪字符串，把第0 2 4 6 8 10 ··· 位的混淆字符删掉
newStr += content.slice(2 * i, 2 * i + 1)
}
// 将结果进行base64解码，至此解密完成
newStr = window.atob(newStr)
// console.log(newStr)
}
结语
官方更新是好事，但是也请一次更新到位，用最好的技术来应对作弊，或者能给学生们一份题库用来背，也能达到学习的目的。
希望世上再无形式主义！
ElementUI的row col布局在span超过24时仍并在一起的解决方案
首先要注意，row的type必须是flex
然后，直接在CSS里加一行：
.el-row {
flex-wrap: wrap;
}
完美解决。
ElementUI的select组件的option的label slot里的错位问题
标题很拗口，但是就是这个意思。
问题
本问题实际描述是，当使用select组件，并且为option使用了插槽之后，像官方里的那样使用style=”float: right;” 后 导致错位，如下图所示
右边的tag贴顶了，但是返回去看官方文档里的代码，却没有问题。
仔细看官方的例子，官方在插槽里用的是纯文本<span></span>，而el-tag也会自动转为span，但依然是样式错误。
在此省略一系列尝试之后，终于发现解决办法，特此记录，以便自己和其他有相同问题的朋友查阅。
解决
在el-tag的外层加一个空格即可解决问题，注意不是键盘上的space，而是
此时错位问题完美解决！

python3 sorted的一个坑
简单记录一下。
有段时间没碰python了，国网结束之后现在开新坑，被sorted坑了，特此记录。
有一个字典dict需要排序，但是排序后先是遇到排序无效，后是遍历时报错
遍历代码：
for key, value in params.items():
if value and not value == '' or value == 0:
sign += str(key) + '=' + str(value) + '&'
检查后发现，是以下地方出问题
1、sorted需要赋值而不是像dict.sort一样直接就变了。忘了赋值。
2、dict在sorted之后变成了list，需要转回dict，直接dict(sorted_list)即可
唉，好久不写这么简单的代码都忘了，手生了。
