我正在使用Beautiful Soup 4来网页抓取配方的HTML页面，而application/ld+json脚本包含以下内容：

有很多\r，\n和间距。如何将其清理成dict，以便我可以访问carbohydrateContent或recipeIngredient等密钥？
使用ast.literal_eval
例如：
import re
import ast
l = ['\r\n{\r\n "@context": "https://schema.org/",\r\n "@type": "Recipe",\r\n "name": "The College Boy",\r\n "url": "https://www.bodybuilding.com/recipes/the-college-boy",\r\n "author": {\r\n "@type": "Person",\r\n "name": "Matt Biss"\r\n },\r\n "image": [\r\n "https://www.bodybuilding.com/images/2018/august/crockpot-4b-header-960x540.jpg",\r\n "https://www.bodybuilding.com/images/2018/august/crockpot-4b-square-600x600.jpg"\r\n ],\r\n "datePublished": "2018-08-27 00:00:00.0",\r\n "publisher": {\r\n "@type": "Organization",\r\n "name": "Bodybuilding.com",\r\n "logo": {\r\n "@type": "ImageObject",\r\n "url": "https://www.bodybuilding.com/images/icons/bb-logo-clean.png",\r\n "width": 666,\r\n "height": 422\r\n }\r\n },\r\n "description": "I call this the "College Boy" because of its simple preparation.

for i in l:
print( ast.literal_eval(re.sub(r'(:\s*\"(.*)\")', r":'\2'", i)) )

从html中提取名称/ url凭据时使用strip（）以避免不必要的东西。
name = output.strip("\r")
url = output.strip( "\n")
然后在dict / json中使用它们
