【问题描述】：
基本上，我现在尝试仅从 sortedOptions 部分中提取所有 SKUs。有人告诉我这是json，不确定是否正确。现在我只拉第一个。我需要指定什么来拉所有这些？
我最初尝试使用正则表达式并且没有提取任何信息，然后我被告知它是 json 并且我需要使用 json。到目前为止，这是我用来从网站上提取任何内容的唯一方法。
然后我的下一步是仅在同一部分中提取stock status 和name。
代码：
import requests
import json
r = requests.get('https://randomwebsite.com/')
pull = r.json()
print " "
string = json.dumps(pull)
parsed_json = json.loads(string)
print parsed_json['name']
print parsed_json['SKU']
网站输出：

【问题讨论】：
-
为什么要把转换后的对象，转回JSON字符串，然后再转回对象？
-
它给了我一个错误，表明它需要是一个字符串，如果你有更直接的方法请告诉我。这是我能够从此页面提取信息的唯一方法
-
您的代码不起作用。
-
@coldspeed 上面的代码输出这个 NIKE Air Vapormax 281460 dropbox.com/s/fxe7q8ksuw5lz9e/…
-
当我尝试运行您的代码时，
r = adapter.send(request, **kwargs)行会导致requests.exceptions.SSLError: [SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed (_ssl.c:661)错误。
