bugku_ctf,web第四题_post

Posted 2023-04-30

参考技术A 这题跟第三题几乎一样,只不过是将get方法换为了post方法。

使用插件如postman， hackbar， http request maker等等，很多插件。选择post模式，然后在 Body Data （也就是请求主体，请求内容）部分输入 what=flag ,提交即可。

第四题

题目：输入某年某月某日，判断这一天是这一年的第几天？

自己的代码如下：

 1 # -*- coding: utf-8 -*-

 8 def leap(year):
 9     index = False
10     if year % 400 == 0:
11         index = True
12     else:
13         if year % 4 == 0 and year % 100 !=0:
14             index = True
15     return index
16 
17 year = int(input(‘please input the year you want to check: ‘));
18 month = int(input(‘please input the month you want to check: ‘));
19 day = int(input(‘please input the day you want to check: ‘))
20 
21 mon_days = [0,31,59,90,120,151,181,212,243,273,304,334];
22 if not leap(year):
23     days = mon_days[month-1]+day;
24 else:
25     if month >= 2:
26         days = month_days[month-1]+1+day
27     else:
28         days = mon_days[month-1]+day;
29 
30 print(‘it is the %dth day.‘ % days)

分析：代码写的很渣，其中很多条件判断可以合到一个if语句中进行判断，对于代码优先级还欠考虑。优点在于领悟到了闰年月份与非闰年月份天数的差异，并根据一个数组实现月份的查询。

如下是标准答案（python-2.7x）。

#!/usr/bin/python
# -*- coding: UTF-8 -*-
 
year = int(raw_input(‘year:\n‘))
month = int(raw_input(‘month:\n‘))
day = int(raw_input(‘day:\n‘))
 
months = (0,31,59,90,120,151,181,212,243,273,304,334)
if 0 < month <= 12:
    sum = months[month - 1]
else:
    print ‘data error‘
sum += day
leap = 0
if (year % 400 == 0) or ((year % 4 == 0) and (year % 100 != 0)):
    leap = 1
if (leap == 1) and (month > 2):
    sum += 1
print ‘it is the %dth day.‘ % sum
