教师端打卡数据自动更新 理论与实践
思路流程
st=>start: 调用chromiumdriver
自动控制chromium
op=>operation: 打开登录页面
输入账号密码并登录
op1=>operation: 调用URL进入
学生日报页面
限制加载时长
time.max = 20s
cond1=>condition: try:
根据未填报按钮
是否正常可使用
判断页面
是否加载成功
op2=>operation: 变量置空
产生班级序号列表
[1，2，3，4]
cond2=>condition: 判断是否存在
未完成打卡班级
op3=>operation: 循环取列表
默认班级序号1~4
op4=>operation: 打开对应班级详细
未完成情况
cond3=>condition: 判断该班级成员
是否全部打卡完成
op5=>operation: 删除对应列表班级值
op6=>operation: 循环取对应学生数
读取学生信息放入变量whj_text中;
cond4=>condition: 是否为最后一名学生
cond5=>condition: 判断当前学生序号
是否为10
op7=>operation: 下一页
cond6=>condition: 判断循环是否结束
op8=>operation: 将变量whj_text
放入html文件中
供公网访问
op9=>operation: 等待片刻
e=>end: 退出chromedriver
运行结束
st->op->op1->cond1
cond1(yes)->op2->cond2
cond1(no)->op1
cond2(yes)->op3->op4->cond3
cond2(no,left)->e
cond3(yes,right)->op5(right)->op3
cond3(no)->op6->cond6
cond6(yes,right)->op8->op9(right)->cond2
cond6(no)->cond4
cond4(yes,right)->op3
cond4(no)->cond5(yes)->op7(left)->op6
cond5(no,left)->op6
