如何使用命令行下载 zip 文件

我想从 dropbox 或 UCF-Crime 视频数据集下载一个高度压缩的 zip 文件。数据集的网站指出这两个链接可以从中获取数据集：

每次我尝试通过 wget 或 curl 下载数据集时都会失败。我知道我尝试的方法不对。我的示例将 visionlab url 作为参数。

wget https://visionlab.uncc.edu/download/summary/60-data/477-ucf-anomaly-detection-dataset/UCF-Anomaly-Detection-Dataset.zip

或者

curl https://visionlab.uncc.edu/download/summary/60-data/477-ucf-anomaly-detection-dataset/UCF-Anomaly-Detection-Dataset.zip

每次尝试时，我都会遇到此错误消息：

ERROR: cannot verify visionlab.uncc.edu's certificate, issued by ...
Unable to locally verify the issuer's authority.
To connect to visionlab.uncc.edu insecurely, use `--no-check-certificate'.

编辑：我尝试通过启用该--no-check-certificate选项来下载数据集。但是，我收到以下消息：

wget --no-check-certificate https://visionlab.uncc.edu/download/summary/60-data/477-ucf-anomaly-detection-dataset/UCF-Anomaly-Detection-Dataset.zip

答案1

当您访问Dropbox 链接，您将找到可供 wget 使用的链接。我尝试了第一个：

wget https://www.dropbox.com/sh/75v5ehq4cdg5g5g/AABvnJSwZI7zXb8_myBA0CLHa?dl=0

此外，您可能需要更新本地证书：

update-ca-certificates -f

答案2

我没有找到直接解决问题的办法，但我实施了一种可以解决 Dropbox 链接问题的变通方法。在朋友的帮助下，我可以提取每个 Dropbox 文件的下载链接。

我把这些 URL 链接放在一个文本文件中UCF-Crime_download_links.txt

您可以通过按照以下步骤尝试下载每个文件来获取这些链接：

在此处输入图片描述

在此处输入图片描述

然后我执行了这个 Python 代码download_ucf-crime.py来下载它们每一个：

import os

filepath = "UCF-Crime_download_links.txt"
file = open(filepath,"r")
lines = file.readlines()
for line in lines:
    line_parts = line.split(',')
    link_filename = line_parts[0]
    link_url = line_parts[1]
    os.system('wget -O %s %s'%(link_filename,link_url))
file.close()

我的朋友建议我检查 dropbox API 以获得更干净的解决方案：https://github.com/dropbox/dropbox-sdk-python
