[英]Reduce script run time in Google Apps Script?
I created a script that tracks attendance for distance learning.我创建了一个脚本来跟踪远程学习的出勤情况。 After a while it times out so I think I am having issues with too many calls to the Google Classroom API, however I don't see a way that I can change it to take those calls out of a loop.过了一会儿,它超时了,所以我认为我对 Google Classroom API 的调用过多有问题,但是我没有看到可以更改它以将这些调用排除在循环之外的方法。
The script takes all the Google Classroom classes that my apps script account is a co-teacher on and using timed triggers creates a daily attendance assignment with one question that says 'here'.该脚本采用我的应用程序脚本帐户作为助理教师的所有 Google 课堂课程,并使用定时触发器创建每日出勤作业,其中有一个问题,上面写着“这里”。 Students are then supposed to answer the question and then another trigger at night runs the function to 'grade' each assignment and populate my spreadsheet so school secretaries can view it in the morning and record the previous days attendance.然后学生应该回答问题,然后另一个触发器在晚上运行该功能以“评分”每项作业并填充我的电子表格,以便学校秘书可以在早上查看并记录前几天的出勤率。
The part that seems to have the bottleneck is my getStudentResponses() function.似乎有瓶颈的部分是我的 getStudentResponses() 函数。 I tried to reduce time by filtering out students that didn't submit the assignment, but it wasn't enough.我试图通过过滤掉没有提交作业的学生来减少时间,但这还不够。 Does anyone see any way that I can make this faster?有没有人看到我可以加快速度的任何方法? I was reading up on using the Cache Service, but I couldn't figure out how to get that to work.我正在阅读有关使用缓存服务的信息,但我不知道如何让它工作。 Any help would be appreciated.任何帮助,将不胜感激。

appendRow
is slow, you should avoid to used it inside a for
loop. appendRow
很慢,你应该避免在for
循环中使用它。 Instead build an array, then pass the values using a single setValues
call.而是构建一个数组,然后使用单个setValues
调用传递值。
