Descarga el video de la estación b a la computadora [válido para pro-test]

Descargue el video de la estación b a la computadora [Pro-test efectivo]
Método 1: use el proyecto python de código abierto de github ---
método de obtención de datos Características: fácil de descargar, velocidad rápida, velocidad garantizada 3 M / s más rápida que Thunder, y parece descargarse de forma predeterminada Es la versión más clara. ¡Lo que descargué es el más claro por defecto! Admite muchos sitios web en el país y en el extranjero: el

método de operación es:
(1) Descargar e instalar python3.7 (el más reciente)
(2) pip3 install you-get
(3) Ingrese "you-get video link" en la herramienta de línea de comandos y haga clic en el botón "Enter" Puedes descargarlo.
Por ejemplo: obtienes https://www.bilibili.com/video/BV1LJ411Y7og?p=6

PD: Otras habilidades prácticas
(1) you-get -i URL vista previa de los parámetros de formato de cada calidad de imagen (solo vista previa, no descarga):
tenga en cuenta que hay una "-i" adicional aquí, puede obtener una vista previa de la descarga primero si la agrega Selección de calidad de imagen, puede ver superdefinición, alta definición, definición estándar y definición de escoria.
you-get -i https://www.bilibili.com/video/BV1LJ411Y7og?p=3

(2) you-get --format = dash-flv URL para descargar el video con los parámetros de calidad de imagen especificados:
reemplazamos la URL con el enlace del video, ingresamos, ingresamos, y puede descargar la calidad de imagen 1080P.
you-get --format = dash-flv https://www.bilibili.com/video/BV1LJ411Y7og?p=3

==============
Además, debido a que un video especial de bili cambia el número de página detrás, ¡puedes escribir un murciélago para descargar por lotes!

Observaciones: Debe ser el entorno python3. El siguiente es el sistema centos7 de mi empresa, el python2 predeterminado, probé python2 pero no funciona, sé que después de instalar yum install python3 directamente, se puede usar de la siguiente manera:
