python - 您如何获得 libtorrent 中 torrent 的总大小？

Question

你如何获得种子文件的总大小？

有什么方法可以获取 torrent 中的文件数量和每个文件的大小？

Answer 1

如果您查看 C++ API，您会发现页面下方的torrent-info和file_iterator方法为您提供了您正在寻找的信息。python 绑定部分指出：

python 接口与 C++ 接口几乎相同。

因此，您应该能够轻松掌握这些方法。

Answer 2

h = ses.add_torrent(params)
s = h.status()
while (not h.is_seed()):
    print s.total_wanted   # prints total size wanted after meta data is obtained, before that 0 is printed.

Answer 3

/usr/local/bin/torrent-size.py

#!/usr/bin/env python3

import libtorrent
import sys

torsize = 0
info = libtorrent.torrent_info(str(sys.argv[1]))
for f in info.files():
    torsize += f.size
print(torsize/1048576, "MB")

这将为您提供作为脚本第一个参数提供的 torrent 的文件大小。以下是安装 libtorrent 和 libtorrent python 绑定的说明。如果你在 Ubuntu 上遇到 cxxstd 的错误，你需要下载 boost 1.76，引导它，安装它，然后将源目录复制到 /usr/share/boost-build 并导出 BOOST_ROOT=/usr/share/boost-build 和导出 BOOST_BUILD=/usr/share/boost-build。

苹果系统：

brew install boost boost-build openssl@1.1 python3
