How to use Python to climb cool my music, many novices are not very clear about this, in order to help you solve this problem, the following editor will explain for you in detail, people with this need can come to learn, I hope you can gain something.

Two days ago, I listened to the music on the official website of Cool my Music. I felt that the music above was good, and I wanted to climb them. At first, I didn't have a clue at all, but in the end, I had a way to implement it, that is, I finally got the music I wanted to hear through two json files.

Insert the Python module needed for the picture description here

The main modules to implement this process are requests, json, urllib.request and urllib.parse, in which the requests module is used to request the corresponding data (in this case, the json data is obtained), and the json module is used to process the obtained json data (converting the json data into a dictionary, mainly using the json.loads () method), urllib.request (using its urlretrieve () method for downloading music), urllib.parse (using its quote () method Used to encode the input string.

Realization idea

First of all, we need to go to the official website of Kuwi Music (http://www.kuwo.cn/)) and enter the keywords in the input box. What the editor enters is: break the cocoon and enter, and you can get the corresponding song list. However, these data are loaded dynamically. If you use the requests module to request this URL directly, it is impossible to get the data. At this time, we can press the computer keyboard F12. When you come to developer mode, click XHR under Network to find the URL of these song lists, specifically:

We need to get the corresponding data in these songs as follows:

The values corresponding to the name and artist keywords are the presentation and final .mp3 file names, and the values corresponding to the rid keyword are used by later procedures.

Of course, it is not easy to access this URL, and you need to add a request header. The reference code is as follows:

MusicName=input ('Please enter the song name:')

EncodName=quote (musicName)

Url=' https://www.kuwo.cn/api/www/search/searchMusicBykeyWord?key={}&pn=1&rn=30&httpsStatus=1'.format(encodName)

Referer=' https://www.kuwo.cn/search/list?key={}'.format(encodName)

# request header

Headers = {

"Cookie": "_ ga=GA1.2.2021007609.1602479334; Hm_lvt_cdb524f42f0ce19b169a8071123a4797=1602479334,1602673632; _ gid=GA1.2.168402150.1602673633; Hm_lpvt_cdb524f42f0ce19b169a8071123a4797=1602673824; kw_token=5LER5W4ZD1C"

"csrf": "5LER5W4ZD1C"

"Referer": "{}" .format (referer)

"User-Agent": "Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/86.0.4240.75 Safari/537.36"

}

Response=requests.get (url=url,headers=headers)

Dict2=json.loads (response.text)

MisicInfo=dict2 ['data'] [' list'] # list of song information

MusicNames=list () # list of song names

Rids=list () # stores a list of songs rid

For i in range (len (misicInfo)):

Name=misicInfo [I] ['name'] +' -'+ misicInfo [I] ['artist']

MusicNames.append (name)

Rids.append (misicInfo [I] ['rid'])

Print ('[{}]-{}-> > {} '.format (random.random () * 10) *' # $', name))

When we choose the songs in the above list to listen, we can find that there is a URL like this at the bottom of the list just now, and there is also a json data in it, which contains the download link of the song I tried to listen to. As follows:

By analyzing this URL, we can see that we need the rid data just now to access the corresponding json data. The URL is: http://www.kuwo.cn/url?format=mp3&rid=**140897945**&response=url&type=convert\_url3&br=128kmp3&from=web&t=1603463521198&httpsStatus=1, maybe the length of the URL obtained by the reader is a little longer than mine. I have removed the last parameter, because I found that without the last parameter, I can still access the corresponding data.

Final code and run result

The reference code is as follows:

From urllib.request import urlretrieve

From urllib.parse import quote

Import requests

Import random

Import json

MusicName=input ('Please enter the song name:')

EncodName=quote (musicName)

Url=' https://www.kuwo.cn/api/www/search/searchMusicBykeyWord?key={}&pn=1&rn=30&httpsStatus=1'.format(encodName)

Referer=' https://www.kuwo.cn/search/list?key={}'.format(encodName)
