Principle

Preface

Since you cannot view your answers again after submitting a test, but you can enter the answering interface to view your answers and continue answering before submission. If you save the link to the answering interface while answering, you can access the saved link after submitting to enter the answering interface and view your answers, but you cannot see whether they are correct or wrong. Therefore, we can work from this answering interface to forcefully view the answer details and correctness.

First, Analyze the Link of the Answering Interface

For example, https://smartcourseexam.zhihuishu.com/ReviewExam/545928/2/3/1836997819974684672/%E6%B0%B4%E7%9A%84%E6%B1%A1%E6%9F%93%E6%8C%87%E6%A0%87%E5%92%8C%E5%87%BA%E8%B7%AF-%E9%97%AE%E7%AD%94%E9%A2%98/1/true/1/0/33791724?examPaperId=33791724&point=0&classId=1617&taskId=2609&isObjective=false&fromSmart=true, which contains several parameters: 545928, 1836997819974684672, %E6%B0%B4%E7%9A%84%E6%B1%A1%E6%9F%93%E6%8C%87%E6%A0%87%E5%92%8C%E5%87%BA%E8%B7%AF-%E9%97%AE%E7%AD%94%E9%A2%98, 33791724, 1617, 2609.

Then Use Developer Mode (F12) to Capture Packets on the Interface Shown Below

From this, we can identify the corresponding parameters for each value in the above link:

smartcourseexam.zhihuishu.com/ReviewExam/examTestId/2/3/courseId/examName/1/true/1/0/paperId?examPaperId=paperId&point=0&classId=classId&taskId=2609&isObjective=false&fromSmart=true

Since some parameters were not mentioned in the response, try removing them and accessing the page. If the page is still accessible, those parameters can be considered non-essential. Then perform exhaustive substitution of the standalone numbers 0,1,2,3 in the link to infer their purposes. The final resulting link is as follows:

smartcourseexam.zhihuishu.com/ReviewExam/examTestId/2/3/courseId/examName/1/true/1/0/paperId?examPaperId=paperId&classId=classId

Among these, the 2 after examTestId controls whether the answering interface displays a countdown timer: 1 means no display, 2 means display. The 1 after examName controls the page display: 0 shows the answering interface, 1 shows the answer review interface.

Conclusion

examTestId, courseId, examName, paperId, and classId can all be obtained by capturing packets on the pre-page before entering the answering interface using developer mode. By constructing a link with these parameters, you can view the corresponding answer results.

Of course, there is an even simpler method... which is to save the link before submitting, or save the link through another account that hasn't completed the assignment. However, note that you need to change the 1 after examName to 2.
