如何在python中使用内置运算符json.dumps将转换为JSON

Question

如何转换为json格式，

我收到一个错误"is not JSON serializable“

以下是我的程序

from urllib2 import urlopen as uReq
import re
from bs4 import BeautifulSoup, Comment
import requests
import json
my_url='https://uae.dubizzle.com/en/property-for-rent/residential/apartmentflat/?filters=(neighborhoods.ids=123)&page=1'

uClient=uReq(my_url)
page_html= uClient.read()
page_soup=BeautifulSoup(page_html, 'html.parser')
comments = page_soup.findAll(text=lambda text:isinstance(text, Comment))
[comment.extract() for comment in comments]
json_output= page_soup.find_all("script",type="application/ld+json",string=re.compile("SingleFamilyResidence")) #find_all("script", "application/ld+json")
#comments = json_output.findAll(text=lambda text:isinstance(text, Comment))
#[comment.extract() for comment in comments]
#json_output.find_all(text="<script type=""application/ld+json"">").replaceWith("")
#print json_output
jsonD = json.dumps(json_output)
uClient.close()

[{"@context":"http://schema.org"，"@type":"SingleFamilyResidence"，“name”：“宽敞2BHK出租大马士革街Al Qusais"，"url":"https://dubai.dubizzle.com/property-for-rent/residential/apartmentflat/2018/4/29/spacious-two-bed-room-available-for-rent-i-2/"，"address":{"@type":"PostalAddress"，”addressLocality“：”迪拜“，”addressRegion“：”迪拜“}，”“：{”@type“：”产品“，”name“：”宽敞2BHK出租大马士革街Al Qusais"，"url":"https://dubai.dubizzle.com/property-for-rent/residential/apartmentflat/2018/4/29/spacious-two-bed-room-available-for-rent-i-2/"，“优惠”：{“@type”：“优惠”，"price":49000，"priceCurrency":"AED"}}，"floorSize":1400，"numberOfRooms":2，"image":"https://dbzlpvfeeds-a.akamaihd.net/images/user_images/2018/04/29/80881784_CP_photo.jpeg"，"geo":{"@type":"GeoCoordinates"，“纬度”：55.3923，“经度”：25.2893}}，{"@context":"http://schema.org"，"@type":"SingleFamilyResidence"，“名称”：“全家具2床房公寓-Al Qusais"，"url":"https://dubai.dubizzle.com/property-for-rent/residential/apartmentflat/2017/10/9/fully-furnished-brand-new-2-bed-room-flat--2/"，"address":{"@type":"PostalAddress"，”addressLocality“：”迪拜“，”addressRegion“：”迪拜“}，”“：{”@type“：”产品“，”名称“：”全家具2床房公寓-Al Qusais"，"url":"https://dubai.dubizzle.com/property-for-rent/residential/apartmentflat/2017/10/9/fully-furnished-brand-new-2-bed-room-flat--2/"，"offers":{"@type":"Offer"，“addressRegion”：700，"priceCurrency":"AED"}}，"floorSize":1400，"numberOfRooms":2，“图像”：“https://dbzlpvfeeds-a.akamaihd.net/images/user_images/2018/09/05/84371522_CP_photo.jpeg”，“地理位置”：{“@type”：“GeoCoordinates”，“纬度”：55.3959，“经度”：25.2959}}]

Answer 1

在更改为json之后，首先将bs4.element.ResultSet转换为字符串

json_data = json.dumps(str(json_output))

Answer 2

Hi添加了BeautifulSoup的另一个包装器，并通过

首先获取文本并使用.get_text()方法，然后使用json.loads

谢谢你，智者。

json_data = json.loads(json_text)
print json_data
