【问题描述】：
我确信这个问题已经被问过一百万次了。我已经阅读了其他一些内容，并且正在努力寻找答案。
我正在大量查询 RIPE api，在 Debian 9 中使用以下 curl 命令：
file="servers-to-ripe.txt"
while IFS= read -r line
do
# Hostnames -> corresponding IPs
dig=$(./ip_extrapolate2 $line| grep -v $resolving_server)
curl --silent "https://stat.ripe.net/data/address-space-usage/data.json?resource="$dig"&data=asn_name" >> servers.json
done <"$file"
这给了我一些 JSON 输出，与所述服务器的所有权有关。我最初使用 jq CLI 解析器，但无济于事。
因此导致我改用 Python 编写它。以下是列表中的前两个对象：

}
]
}
}{
我试图只提取 asn_name 和 IP 范围。
我已经修改了 Python (2.7) 的内置 json 解析器。这是我尝试过的：
#!/usr/bin/python
import json
input_file = open ('servers.json')
json_array = json.load(input_file)
servers = []
for item in json_array:
server_asn_name = {"asn":None, "resource":None}
server_asn_name['asn'] = item['asn_name']
server_asn_name['resource'] = item["resource"]
servers.append(server_asn_name)
print(server_asn_name)
还有一些其他的，但这可能是我迄今为止得到的最接近的。任何建议将不胜感激:)
【问题讨论】：
-
请注意，一旦您加载了 JSON，它就是常规的
dict、list和/或原始类型。因此，您可以像在手动创建的列表或字典中一样查找数据。看看如何从 JSON 中提取数据是一个红鲱鱼。 -
您能说明一下您使用的是哪个版本的 Python 吗？我也不确定这里到底是什么问题。
-
这是 Python 2.7.13，在 Debian 9 上
