目标URL: http://quotes.toscrape.com/js/
目标内容:网页内容,如:The world as we have created it is a process of our thinking. It cannot be changed without changing our thinking.” by Albert Einstein
问题:去除头部字符串后,无法生成合适的Json数据。
import requests
import json
from bs4 import BeautifulSoup
url = "http://quotes.toscrape.com/js/"
r = requests.get(url)
soup = BeautifulSoup(r.text,"lxml")
print(r.status_code)
a = soup.findAll("script")[1].get_text()
b = a[a.find("{"):a.find("];")-1]
print(b)
json_data = json.loads(b)
报错信息如下:200
Traceback (most recent call last):
File "F:\01_Python\try.py", line 1878, in <module>
json_data = json.loads(b)
File "C:\Python36\lib\json\__init__.py", line 354, in loads
return _default_decoder.decode(s)
File "C:\Python36\lib\json\decoder.py", line 342, in decode
raise JSONDecodeError("Extra data", s, end)
json.decoder.JSONDecodeError: Extra data: line 14 column 6 (char 450)
打印b的格式如下,为了简便起见,删除了里面若干行材料:{
"tags": [
"change",
"deep-thoughts",
"thinking",
"world"
],
"author": {
"name": "Albert Einstein",
"goodreads_link": "/author/show/9810.Albert_Einstein",
"slug": "Albert-Einstein"
},
"text": "\u201cThe world as we have created it is a process of our thinking. It cannot be changed without changing our thinking.\u201d"
},
{
"tags": [
"abilities",
"choices"
],
"author": {
"name": "J.K. Rowling",
"goodreads_link": "/author/show/1077326.J_K_Rowling",
"slug": "J-K-Rowling"
},
"text": "\u201cIt is our choices, Harry, that show what we truly are, far more than our abilities.\u201d"
},
{
"tags": [
"humor",
"obvious",
"simile"
],
"author": {
"name": "Steve Martin",
"goodreads_link": "/author/show/7103.Steve_Martin",
"slug": "Steve-Martin"
},
"text": "\u201cA day without sunshine is like, you know, night.\u201d"
}
所以现在卡在无法将b转变成合适的json数据,请教各位大神帮帮忙,谢谢!
另外,已经尝试过一些简单的验证,包括验证b的头部和尾部,替代\n和空格,但依然报错。

数据的格式是字典组成的列表
你的b的字符串是一个大括号包着的许多字典就成了集合set
是没法loads的
b = a[a.find("["):a.find("];")+1]
用原本的格式试试
