これは長いオプションですwebsocat：
(base) isysrg@isysresearch:~/tmp$ ./websocat --help=long option
websocat 1.12.0
Vitaly "_Vi" Shukela <[email protected]>
Command-line client for web sockets, like netcat/curl/socat for ws://.
USAGE:
websocat ws://URL | wss://URL (simple client)
websocat -s port (simple server)
websocat [FLAGS] [OPTIONS] <addr1> <addr2> (advanced mode)
FLAGS:
--stdout-announce-listening-ports [A] Print a line to stdout for each port being listened
--async-stdio [A] On UNIX, set stdin and stdout to nonblocking mode instead of
spawning a thread. This should improve performance, but may break other
programs running on the same console.
--compress-deflate [A] Compress data coming to a WebSocket using deflate method. Affects
only binary WebSocket messages.
--compress-gzip [A] Compress data coming to a WebSocket using gzip method. Affects only
binary WebSocket messages.
--compress-zlib [A] Compress data coming to a WebSocket using zlib method. Affects only
binary WebSocket messages.
--dump-spec [A] Instead of running, dump the specifiers representation to stdout
-e, --set-environment Set WEBSOCAT_* environment variables when doing exec:/cmd:/sh-c:
Currently it's WEBSOCAT_URI and WEBSOCAT_CLIENT for
request URI and client address (if TCP)
Beware of ShellShock or similar security problems.
-E, --exit-on-eof Close a data transfer direction if the other one reached EOF
--foreachmsg-wait-read [A] Wait for reading to finish before closing foreachmsg:'s peer
--jsonrpc Format messages you type as JSON RPC 2.0 method calls. First word
becomes method name, the rest becomes parameters, possibly automatically
wrapped in [].
--jsonrpc-omit-jsonrpc [A] Omit `jsonrpc` field when using `--jsonrpc`, e.g. for Chromium
--just-generate-key [A] Just a Sec-WebSocket-Key value without running main Websocat
--linemode-strip-newlines [A] Don't include trailing \n or \r\n coming from streams in WebSocket
messages
-0, --null-terminated Use \0 instead of \n for linemode
--no-line [A] Don't automatically insert line-to-message transformation
--no-exit-on-zeromsg [A] Don't exit when encountered a zero message. Zero messages are used
internally in Websocat, so it may fail to close connection at all.
--no-fixups [A] Don't perform automatic command-line fixups. May destabilize
websocat operation. Use --dump-spec without --no-fixups to discover what
is being inserted automatically and read the full manual about Websocat
internal workings.
--no-async-stdio [A] Inhibit using stdin/stdout in a nonblocking way if it is not a tty
-1, --one-message Send and/or receive only one message. Use with --no-close and/or -u/-U.
--oneshot Serve only once. Not to be confused with -1 (--one-message)
--print-ping-rtts Print measured round-trip-time to stderr after each received WebSocket
pong.
--exec-exit-on-disconnect [A] Make exec: or sh-c: or cmd: immediately exit when connection is
closed, don't wait for termination.
--exec-sighup-on-stdin-close [A] Make exec: or sh-c: or cmd: send SIGHUP on UNIX when input is
closed.
--exec-sighup-on-zero-msg [A] Make exec: or sh-c: or cmd: send SIGHUP on UNIX when facing incoming
zero-length message.
-q Suppress all diagnostic messages, except of startup errors
--reuser-send-zero-msg-on-disconnect [A] Make reuse-raw: send a zero-length message to the peer when some
clients disconnects.
-s, --server-mode Simple server mode: specify TCP port or addr:port as single argument
-S, --strict strict line/message mode: drop too long messages instead of splitting
them, drop incomplete lines.
--timestamp-monotonic [A] Use monotonic clock for `timestamp:` overlay
-k, --insecure Accept invalid certificates and hostnames while connecting to TLS
--udp-broadcast [A] Set SO_BROADCAST
--udp-multicast-loop [A] Set IP[V6]_MULTICAST_LOOP
--udp-oneshot [A] udp-listen: replies only one packet per client
--udp-reuseaddr [A] Set SO_REUSEADDR for UDP socket. Listening TCP sockets are always
reuseaddr.
--uncompress-deflate [A] Uncompress data coming from a WebSocket using deflate method.
Affects only binary WebSocket messages.
--uncompress-gzip [A] Uncompress data coming from a WebSocket using deflate method.
Affects only binary WebSocket messages.
--uncompress-zlib [A] Uncompress data coming from a WebSocket using deflate method.
Affects only binary WebSocket messages.
-u, --unidirectional Inhibit copying data in one direction
-U, --unidirectional-reverse Inhibit copying data in the other direction (or maybe in both directions
if combined with -u)
--accept-from-fd [A] Do not call `socket(2)` in UNIX socket listener peer, start with
`accept(2)` using specified file descriptor number as argument instead
of filename
--unlink [A] Unlink listening UNIX socket before binding to it
-V, --version Prints version information
-v Increase verbosity level to info or further
-b, --binary Send message to WebSockets as binary messages
-n, --no-close Don't send Close message to websocket on EOF
--websocket-ignore-zeromsg [A] Silently drop incoming zero-length WebSocket messages. They may
cause connection close due to usage of zero-len message as EOF flag
inside Websocat.
-t, --text Send message to WebSockets as text messages
--base64 Encode incoming binary WebSocket messages in one-line Base64 If
`--binary-prefix` (see `--help=full`) is set, outgoing WebSocket
messages that start with the prefix are decoded from base64 prior to
sending.
--base64-text [A] Encode incoming text WebSocket messages in one-line Base64. I don't
know whether it can be ever useful, but it's for symmetry with
`--base64`.

addresses) to use. See --help=types for info about address types. If this is an address for

websocat上記のnginxサイト構成に基づいて、そのコマンドは何ですか？websocatオプションが多すぎるため、可能であると確信しています。それとも別の単純なWebソケットサーバーユーティリティがありますか？
ベストアンサー1
最も近いWebsocatコマンドラインは次のとおりです。
websocat --restrict-uri /vless-ws -bE ws-l:0.0.0.0:8080 --binary-prefix B --text-prefix T ws://127.0.0.1:19002
しかし、まだ不完全な部分がたくさんあります：
- 断線検知遅延
- Ping応答は、最終エンドポイントではなくWebsocatによって応答されます。
- メッセージサイズは Websocat バッファサイズによって制限されます。
X-Real-IP満たされていない- 一致のみ可能
/vless-ws、一致しない、/vless-ws/または/vless-ws/something。
なぜ127.0.0.1：19002をポート8080として公開しないのですか？ここに記載されていないNginx設定ファイルには他に何がありますか？
以下も使用できます。キャディNginxの代わりに、次の簡単な設定ファイルを使用して、root以外のユーザーとして簡単に実行できます。
{
admin off
}
:8080
handle_path /vless-ws/* {
reverse_proxy http://127.0.0.1:19002
}
明らかにWebsocket接続が渡されるので、これらのヘッダーを手動で指定する必要はありません。
websocatには多くのオプションがあるので、これができると確信しています。
Websocat（少なくともバージョン1以降）は、--restrict-uriオプション-Fなどのいくつかの例外を除いて、さまざまな着信URLを異なる方法で処理するようには設計されていません。ユーザーは、Webサーバーや一般的なツールなどの他のツールを使用してsocat失われたコンテンツを見つけることができると予想されます。他のツールで Websocat を使用するいくつかの例は、次のドキュメントで説明されています。その他の例.md。
