python 循环 subprocess.check_output

Question

I want to do some data research about student's result in their final examination on http://diemthi.hcm.edu.vn/ enter image description here In this page you need to insert your "SoBaoDanh" to search your point at you final test

For example enter image description here enter image description here "SoBaoDanh" start form 02000001 to 02089275 So how I can get hole of that result My code I wrote like this

import subprocess    
i = 2000001
    while i < 2089275:  
        result = subprocess.check_output([print("'curl - F" + '"SoBaoDanh=0'+ str(i+1) +'"' + "diemthi.hcm.edu.vn/Home/Show'")])
        print(result)
    i +=1

Answer 1

Instead of calling curl using subprocess , use the requests library to make http requests like so

import requests as r
for i in range(2000001, 2089275):
   res = r.post("http://diemthi.hcm.edu.vn/Home/Show", data={"SoBaoDanh": "0"+str(i)}) 
   print(res.content)

Since the result is an HTML document, you could use an HTML parser like bs4 to further filter the result stored in res.content to get only the part that you need.
