qzx downloadFile

作用

从互联网下载文件,方式类似 wget 或 curl。

命令成熟度:Alpha

可用于真实使用和反馈,但其接口与行为仍可能继续演进。 这是当前开发 checkout 的评估。未来每个不可变发布标签都会保留该版本中包含的准确评估。 可在 PyPI 0.2.2.0.9 使用。文档对应 alpha checkout 0.2.2.0.9。

行为与内置保护

实际模式会应用你请求的更改

此操作直接执行

无需调用原生程序即可运行

为文档所述任务使用网络

设计为无需提权即可运行

无需确认即可创建新目标。除非明确使用 --overwrite,否则现有目标保持不变;替换前会创建带故障保护的安全备份。仅接受绝对 HTTP/HTTPS URL,应用超时限制,并以原子方式完成最终替换。

QZX 会在实际更改前创建恢复文件;只有在你明确决定故意跳过它时才使用 --dangerously-bypass-approvals-and-sandbox/--yolo。

此安全分类由 OpenAI GPT-5.6 Pro 于 2026-08-25 对照实现摘要 sha256:bfba9193ca946ab5eb99d10987b6d6103468ff086964a3dc21d3237d2a022a34 审阅。

准确语法

qzx downloadFile <url> <destination_path> [show_progress] [timeout] [overwrite] --json

参数

滑动或使用横向滚动条查看所有列。

名称类型必填默认值描述
urlstr未声明要下载的文件 URL
destination_pathstr未声明下载文件的保存路径
show_progressbooltrue是否显示下载进度
timeoutint30最大等待时间(秒)
overwriteboolfalse创建安全备份后替换现有目标

输入示例

qzx downloadFile https://example.com/file.txt downloads/file.txt

下载示例文件

qzx downloadFile https://example.com/file.zip downloads/file.zip false

下载文件但不显示进度

qzx downloadFile https://example.com/large-file.iso downloads/file.iso true 120

使用延长的超时下载大文件

qzx downloadFile https://example.com/file.txt downloads/file.txt --overwrite

创建安全备份后替换现有文件

要获得完整结构化载荷,请添加 --json: qzx downloadFile <url> <destination_path> [show_progress] [timeout] [overwrite] --json
