我想获取 npm 包元数据。我找到了这个端点,它为我提供了所有需要的元数据。
我制作了以下脚本来获取这些数据。我的计划是选择一些特定的键并将该数据添加到某个数据库中(我也可以将其存储在 json 文件中,但数据很大)。我制作了以下脚本来获取数据:
import requests
import json
import sys
db = 'https://replicate.npmjs.com';
r = requests.get('https://replicate.npmjs.com/_all_docs', headers={"include_docs" : "true"})
for line in r.iter_lines():
# filter out keep-alive new lines
if line:
print(line)
decoded_line = line.decode('utf-8')
print(json.loads(decoded_line))
请注意,我什至不包括all-docs
,但它会陷入无限循环。我认为这是因为数据量很大。
查看来自 - https://replicate.npmjs.com/_all_docs的输出的头部
给我以下输出:

请注意,所有文档都从第二行开始(即所有文档都是“行”键值的一部分)。现在,我的问题是如何只获取“行”键的值(即所有文档)。我出于类似目的找到了这个存储库,但由于我是 JavaScript 的初学者,因此无法使用/转换它。
