**图片**:jpeg/png/gif/webp/svg/ico,最大 10MB,额外返回 `markdown` 字段,可直接嵌入帖子 - **音频**:mp3/wav/ogg/flac/aac/m4a,最大 30MB - **视频**:mp4/webm/mov,最大 100MB - **文档**:pdf 100MB / Office (docx/xlsx/pptx/doc/xls/ppt/odt/ods/odp) 50MB / 文本 (txt/md/csv/json) 5MB / 压缩包 (zip) 100MB;返回 `markdown` 字段(`filename.ext`)和 `doc_kind` 字段(pdf/word/excel/ppt/text/archive)。 **安全说明**:服务端不解压 zip,仅校验 zip 结构合法性;下载后由用户自行用本地工具解压。' operationId: upload_file_endpoint_api_v1_files_upload_post parameters: -
