摘要

之前未开学之前，是信息表采集，开学之后，改成了循环签到和查寝，那就想着再写个脚本

正文

站在巨人的肩膀上，所以该代码全部开源，我也借鉴的大佬的东西，放在第三节致谢。有问题可以在下面进行留言讨论！

一、自动每日签到

源码

1.1 思路

抓包（抓包的流程，可以参照我之前的文章）
每日接口获取最新表单
通过上步的id获取详细表单
通过上步获取该表单的选项id

如果整体的思路看不明白，可以参照下面的详细步骤

1.1 获取最新表单

}

其中我们需要获取signWid514213和signInstanceWid4146

获取我需要的两个参数，体温选项499882和身体是否异常选项499884

1.3 模拟提交

最后通过上面步骤获取到的4146,499882,499884以及自定义的地址，进行签到

1.4 运行结果

二、自动每日查寝

源码

2.1 思路

抓包（抓包的流程，可以参照我之前的文章）
每日接口获取最新表单
通过上步的id获取详细表单
通过上步获取该表单的选项id

2.2 接口

获取最新查寝

html
1
/wec-counselor-attendance-apps/student/attendance/getStuAttendacesInOneDay

获取详细查寝

html
1
/wec-counselor-attendance-apps/student/attendance/detailSignInstance

提交查寝

html

/wec-counselor-attendance-apps/student/attendance/submitSign

2.3 随机图片

今日校园的图片，是存储到了阿里云，阿里云有官方开源的sdk，支持各种语言，自己去下相应的sdk来实现上传即可。

阿里云对象存储OSS功能文档

当然，你也可以尝试用代码实现自动往阿里云提交，但是我还是觉得太麻烦，就放弃了。

我采用的方法，是一次性上传多张照片，然后写了一个随机函数返回照片

	"signPhotoUrl": "null", //这个地方的图片链接，原本我以为可以存放自己服务器照片，后来发现不行，有域名验证
	"position": "null",
	"qrUuid": "null"
}

三、获取今日校园阿里云oss账号

3.1 前言

10月22日，学校换了新的签到，要拍照。

在提交今日校园照片的时候，无意间抓包到一系列数据，然后，看了阿里云oss的文档之后，顿时明白了许多。

终于知道为啥好多人挤破头颅都要去阿里了。
阿里，就是牛逼，就连上传的所有可能用到的比较人性化的功能（比方说上传进度条功能），都给整完了。
就连我这种菜鸡，都能拿来就可以用。
我曾经听过某大佬说，真正的开发者，写的代码，不仅条理清楚，还通俗易懂。这用来形容阿里再合适不过了。
这是不是就是真正的宗师境界呢？
原谅我太过激动，这也更让我坚定了，要努力学习，进大厂的愿望

3.2 正题

今日校园获取阿里云OSS的接口

html

/wec-counselor-sign-apps/stu/sign/getStsAccess

请求头中携带自己的cookie

获取如下信息，然后用id、secret、token，再结合阿里开源

此处我也遇到了很多问题，比方说有token经常报错不对，那就继续抓包，在上传照片的请求体中，会获得x-oss-security-token
再将token换成x-oss-security-token即可登录今日校园oss，当然，这并不是永久有效的，但是依然有最高权限，比方说删除之类~
注意：
不要乱删除内容哦~
