Netease cloud sign in lottery? That year I could sign in for 365 days. No? Look.

Preface

      Hello everyone , Here is a data acquisition , Whether in life or at work , For us programmers , Headphones can be said to be an essential tool , Bring it to work , Put it outside when driving , I also wear it on the bus and subway . So what kind of music software do you usually use ？ Then I'll come first . I only use Netease cloud , The others are basically unused . use QQ Music can be reviewed 1, Netease cloud button 2, Cool dog button 3. Should basically use these three . Welcome to comment on your music software , There are surprises in the comments .

      

        One of the reasons why I use Netease cloud is that there are some touching comments under the song . So I like . Well, there's a lot of nonsense , Now let's get to the main topic

Text

        In fact, many websites have sign in lottery , Or sign in and send gifts , Today is also idle and boring , The boss can't find me fishing . So let's give you a small case . Today's case is the Netease cloud auto sign in script , You deserve it .

Since we need to sign in , First , Naturally, you need to simulate login , Here we are still simply using our open source DecryptLogin Library to achieve Netease cloud music simulation login ：

''' Simulated Login '''@staticmethoddef login(username, password):  lg = login.Login()  _, session = lg.music163(username, password)  return session

  After successful login , Let's analyze how to realize the automatic check-in of Netease cloud music . Press F12 Open developer tools , Then click the sign in button of Netease cloud music ：

                                   

  Then I'm grade nine , Is there anything higher than me ？ I don't think so .

We'll find a suspected sign in post request ：

 

Its link is composed of ：

'https://music.163.com/weapi/point/dailyTask?csrf_token=' + csrf

In previous articles, we said ,csrf This parameter is used after login cookies You can find , Like this ：

csrf = re.findall('__csrf=(.*?) for', str(session.cookies))[0]

So the problem we need to solve now is how to find the post The request needs to be submitted data Original text , Because what you see on the web page is encrypted , Just like this. ：

I don't know why I intuitively want to search first daily Keyword ( Because it is still a direct analysis js Code break point ,

The first is obviously that we found the check-in interface , Then click the second one to have a look ：

query It can't be the original we want . try ？ If you try to succeed, it's not blood ？ therefore , Call DecryptLogin Netease cloud music written in Library post Parameter encryption algorithm , Let's encrypt it data( Netease cloud music all post Requested and carried data The original text should be encrypted with an encryption algorithm before submission )：

from DecryptLogin.platforms.music163 import Cracker

cracker = Cracker()
#  notes : typeid by 0 representative APP Sign in ,  by 1 The representative signs in on the website 
data = {
          'type': typeid
        }
data = cracker.get(data)

Then send a request to test it ：

​​​​​​​

signin_url = 'https://music.163.com/weapi/point/dailyTask?csrf_token=' + csrf
headers = {
      'User-Agent': 'Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/79.0.3945.130 Safari/537.36',
      'Content-Type': 'application/x-www-form-urlencoded',
      'Referer': 'http://music.163.com/discover',
      'Accept': '*/*'
    }
res = self.session.post(signin_url, headers=headers, data=data)

It is found that the returned data is like this ：

This result shows that our conjecture is completely correct , Just because we've checked in , That's why duplicate check-in is displayed . Last , In order to save the time of entering the account password on the command line every day , We can add a few lines of code to the front of the script ：

​​​​​​​​​​​​​​
if os.path.exists('config.json'):
  f = open('config.json', 'r', encoding='utf-8')
  info = json.load(f)
  f.close()
else:
  args = parseArgs()
  info = {'username': args.username, 'password': args.password}
  f = open('config.json', 'w', encoding='utf-8')
  json.dump(info, f)
  f.close()

Explain what the code means , That is, if there is... In the current folder config.json This file ：

So let's go straight from this json Read the user's account name and password in the file , Otherwise, start the command line parameter parsing function ：

​​​​​​​

''' Command line parameter parsing '''
def parseArgs():
  parser = argparse.ArgumentParser(description=' Netease cloud music automatically signs in ')
  parser.add_argument('--username', dest='username', help=' user name ', type=str, required=True)
  parser.add_argument('--password', dest='password', help=' password ', type=str, required=True)
  args = parser.parse_args()
  return args

Let the user enter the account password manually , And automatically save to config.json In this file , So you don't have to re-enter your account password next time .

All done~ Follow the official account below for the complete source code

Effect display

Operation mode ：

python signin.py --username  user name  --password  password 

Because it involves the account password , Just code it . Just cut an effect picture , Because I signed in once during the test , Therefore, running the script to check in again will show that the check-in failed because of repeated check-in , Too lazy to find a new account

  Let me see which brother can be higher than me .
