python2 verification code recognition

Today, I will give you an analysis of the simple solution to the problem of verification code recognition, and start the lecture:

First of all, this is a string of verification code links:

https://credit.wsjd.gov.cn/portal/captcha 
Then we parse this string of links, and then use pytesseract and PIL to identify the verification code. Not much nonsense, just start it directly, the code:

import pytesseract
import urllib2
from PIL import Image
import sys
reload(sys)
sys.setdefaultencoding('utf-8')
headers = {
    'Accept': 'text/html,application/xhtml+xml,application/xml;q=0.9,image/webp,image/apng,*/*;q=0.8',
    'Accept-Encoding': 'gzip, deflate, br',
    'Connection': 'keep-alive',
    'Host': 'credit.wsjd.gov.cn',
    'Upgrade-Insecure-Requests': '1',
    'User-Agent': 'Mozilla/5.0 (Windows NT 6.1; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/66.0.3359.139 Safari/537.36',
}
url = 'https://credit.wsjd.gov.cn/portal/captcha'
request = urllib2.Request(url,headers=headers)
res = urllib2.urlopen(request).read()
try:
    captchaFile = 'yishi/static/images/credit_captcha.png'#This is to create a file to store the parsed verification code
    with open(captchaFile, 'wb') as f:
        f.write(res) #Identify 
　　the verification code
    image = Image.open(captchaFile)
    captcha_value = pytesseract.image_to_string(image)
    print 'The verification code is: '+captcha_value
except IOError,e:
    #Verification code failed to re-request
    print('Failed to get verification code')
    print (s)
