现有一个 json 文件，希望下载其中所有的 “ url ” 的文件：

http://a1.phobos.apple.com/us/r1000/000/Features/atv/AutumnResources/videos/entries.json

如何在 Linux 上批量下载呢？使用 wget 一个个复制粘贴效率太低了。

解析 json，对每个 url 执行 wget 命令

sed 一下就出来了, 不会的话用[jq]( https://stedolan.github.io/jq/)

优雅一点的，用程序解析 json 中的 url，然后下载
暴力点的，正则出 url

sed | awk | wget 搞定

import json
file = open('pathToFile')
file_to_json = json.load(file)
for a in file_to_json:
for b in a['assets']:
print(b['url'])
wget 或者 requests 搞定。

```
curl http://a1.phobos.apple.com/us/r1000/000/Features/atv/AutumnResources/videos/entries.json | grep url | sed -e 's/"url"\ ://;s/\,//g' | awk '{print "curl -L -O "$1}' | sh
```

作为 windows 党，推荐.net core 和 powershell，先复制 json 内容至剪切板
[string]$a = get-clipboard
$b = ConvertFrom-Json -InputObject $a
$b.assets.url
就拿到了所有 url，再当成数组一个个遍历，多线程用 wget 下载就行了

win linux 通用 powershell：

$a = Invoke-RestMethod http://a1.phobos.apple.com/us/r1000/000/Features/atv/AutumnResources/videos/entries.json |ConvertFrom-Json
$a.assets.url
和楼上的道理一样。只不过这个网址现在好像，啥命令都不行了，502 Bad Gateway 了。

命令行玩的 6

$url = 'http://a1.phobos.apple.com/us/r1000/000/Features/atv/AutumnResources/videos/entries.json'
$a = Invoke-RestMethod -Uri $url
$a.assets.url
测试通过
我不知道网址内容是否变了，反正现在不需要搞 json 了。

jshon 了解一下
-e xxxx -e url1 -u`
curl -s ...

用 jq 来处理很简单：
curl -L http://a1.phobos.apple.com/us/r1000/000/Features/atv/AutumnResources/videos/entries.json | jq -r '.[].assets | .[].url' | xargs -I {} curl -LO {}
