Analyze the real address of the music
Choose a song to take Chen Li's horse riding as an example
Open the developer tools, select network -> media -> refresh the webpage to get the real address of the music
However, the obtained address cannot be read when viewing the source code. It must be hidden by Baidu Music. There are generally two situations at this time. The first is to use JavaScript to splice or encrypt the request connection, and the second is to hide the data. Because we don’t know what happened. So we can only slowly analyze the requested data.
After analysis, we can see that the real music address exists in this API http://musicapi.taihe.com/v1/restserver/ting?method=baidu.ting.song.playAAC&format=jsonp&callback=jQuery17206453751179783578_1544942124991&songid=243093242&from=web&_= 1544942128336
And what we request this API to return is a json data (that is, the dictionary data type of python). As long as we use the rules of the dictionary, we can extract all our data.
url stitching to get all data
Earlier we got the real address of the music, and then we analyze the url of the real address, hoping to get the secret to downloading all the music.
A careful analysis of the url will reveal that the from parameter and _ after the? Do not affect the data request even if it does not exist.
And the songid in the following parameters is actually the unique id of the song, and the from parameter actually indicates which platform it came from.
So when we download music, as long as we get the songid of the song in batches, we can download all the songs.
Get singid in batch
Using developer tools, you can view the location of songid by viewing the source code of the webpage. If we analyze the URL of a singer page, you will find that the same can be constructed.
At this point, the entire web page analysis is over.
