它提供了专门的分段下载器,对并行度、连接策略和协议版本有精细控制,同时提供了可复用的 Go 库供程序化使用。
A small segmented downloader for CLI and Go programs.
piko can save to a file, discard output for speed tests, or return downloaded bytes to your own code. It supports HTTP protocol selection, connection strategies, custom DNS resolvers, proxies, retries, and progress callbacks.
piko currently supports HTTP range/segmented downloads. For ordinary single-stream downloads, use curl instead.
go install github.com/UruhaLushia/piko/cmd/piko@latest
Or download prebuilt binaries from GitHub Releases.
