h2i是一个一个交互式的HTTP/2(“H2”)控制台调试器。
Features:
- send raw HTTP/2 frames
- PING
- SETTINGS
- HEADERS
- etc
- type in HTTP/1.n and have it auto-HPACK/frame-ify it for HTTP/2
- pretty print all received HTTP/2 frames from the peer (including HPACK decoding)
- tab completion of available commands </ul>
- unnecessary CONTINUATION frames on short boundaries, to test peer implementations
- request bodies (DATA frames)
- auto-completion of subcommands and options
- send invalid frames for testing server implementations (supported by underlying Framer)
Not yet features, but soon:
