Although the URL of some songs in the music library exists, the music can no longer be downloaded according to URL.

Nginx displays a 404 error.

Verify that the URL of the songs in the database can be downloaded

First of all, export the song URL in the database to a file. The following format (song ID, music address type, path)

1000 Beijing Accountability URL; / 00/00/00001000_accompaniment.m4a

Then use the program to scan the URL

Org.apache.logging.log4j

Log4j-api

2.7

Org.apache.logging.log4j

Log4j-core

2.7

Io.netty

Netty-all

4.1.0.Final

The program is crappy. We need to learn about object encapsulation in the future.
