Description
问题描述
使用 im +messages-resources-download 下载飞书消息附件时失败。
附件为 JSON 文件,原始大小是 13067 字节,但 CLI 提示响应包含 13107 字节,比声明长度多 40 字节。
复现命令
lark-cli im +messages-resources-download \
--as user \
--message-id <message_id> \
--file-key <file_key> \
--type file \
--output downloaded.json \
--format json
使用 --as user 和 --as bot 都会失败。
错误信息
lark-cli 1.0.86:
range response delivered more than the 13067 bytes its framing declared
lark-cli 1.0.68:
chunk overflow: delivered 13107, expected 13067
预期行为
能够正常下载原始的 13067 字节文件。
环境

文件名:1784686506840_101705.json

Research direction
Start by locating the implementation of the im +messages-resources-download command and the range-response length validation. Reproduce the Windows download with the attached 13067-byte JSON file, then verify that the command writes exactly the original 13067 bytes for both user and bot authentication.
