测试使用断点续传

一、wget测试

咱们使用wget测试:

  1. 请求完整的文件
 root@Loli  ~ wget -c --no-check-certificate https://127.0.0.1:28205/test/range
--2025-03-13 00:12:11--  https://127.0.0.1:28205/test/range
Loaded CA certificate '/etc/ssl/certs/ca-certificates.crt'
Connecting to 127.0.0.1:28205... connected.
WARNING: The certificate of ‘127.0.0.1’ is not trusted.
WARNING: The certificate of ‘127.0.0.1’ doesn't have a known issuer.

Saving to: ‘range’

range                         100%[==============================================>] 550.66K  --.-KB/s    in 0.002s  

2025-03-13 00:12:11 (306 MB/s) - ‘range’ saved [563873/563873]
  1. 删除文件的后面部分, 让wget从中断的地方继续下载 (模拟中断)
 root@Loli  ~ truncate -s 300K range
  1. 继续请求完整的文件
 root@Loli  ~ wget -c --no-check-certificate https://127.0.0.1:28205/test/range
--2025-03-13 00:12:53--  https://127.0.0.1:28205/test/range
Loaded CA certificate '/etc/ssl/certs/ca-certificates.crt'

range                         100%[+++++++++++++++++++++++++=====================>] 550.66K  --.-KB/s    in 0.001s  

2025-03-13 00:12:53 (456 MB/s) - ‘range’ saved [563873/563873]

可以发现它从中断的地方重新开始了, 而 不是 从头开始!

因此得证, 项目支持断点续传~

二、IDM测试

非常简单, 只需要点击下载即可:

idm

Tip

(图片是暂停的了, 已经测试了多次断开是可以继续的(断点续传嘛)) 目前服务器部署在VM上, 因此由于虚拟化、DEBUG运行、https等原因, 它的性能大大下降! (而且我的游戏本还没有插电源...)

基准: 我通过vscode拖拽上传这个mp4文件的速度是在 8 ~ 9 MB/s 左右

三、aria2多线程下载测试

安装aria2:

sudo pacman -S aria2

启动程序, 然后多线程下载:

aria2c -x 16 -s 16 --check-certificate=false "https://127.0.0.1:28205/range/misaka.mp4"

实际运行结果:

 root@Loli  ~ aria2c -x 16 -s 16 --check-certificate=false "https://127.0.0.1:28205/range/misaka.mp4"

可以发现, 几乎是没有兼容性问题的, 大大滴正确! (同时也测试了多次在下载的时候ctrl+c取消下载, 即中断, 但是依旧可以成功下载 (断点续传的))

更多的运行输出: 
# `-c`是指定断点续传
aria2c -c -x 16 -s 16 --check-certificate=false -o misaka.mp4.part "https://127.0.0.1:28205/range/misaka.mp4"

aria2 will resume download if the transfer is restarted.
If there are any errors, then see the log file. See '-l' option in help/man page for details.

操作说明: 运行下载后, 马上 ctrl + c 断开了

aria2c 记录了未完成的部分:

Download GID#8036614ece916072 not complete: /root/misaka.mp4.part

服务器没有报错，aria2 也提示:

aria2 will resume download if the transfer is restarted.

第二次使用 -c 继续下载:

下载从 98% 继续, 而不是从 0% 开始:

最终: Download complete: /root/misaka.mp4.part
