Python 我在下面发布的数据，我想上传到django模型，并希望将图像链接转换为本地主机链接

获取json对象中的数据，并使用字符串替换来更改url域

{
    "news_by": "Entertainment ",
    "news_title": "'Sarileru Neekevvaru' teaser: Mahesh Babu is visually pleasing, but Prakash Raj takes the cake again",
    "news_description": "Mahesh Babu is a pleasure to the eye, much like always, and 'Sarileru Neekevvaru' teaser is high on style quotient too, but Prakash Raj will win you over once again",
    "image_link":"https://cdn.dnaindia.com/sites/default/files/styles/third/public/2019/11/22/882305-sarileru-neekevvaru-teaser.jpg"
  }

使用JSONField（）保存数据。。

import json
j = """{ "news_by": "Entertainment ", "news_title": "'Sarileru Neekevvaru' teaser: Mahesh Babu is visually pleasing, but Prakash Raj takes the cake again", "news_description": "Mahesh Babu is a pleasure to the eye, much like always, and 'Sarileru Neekevvaru' teaser is high on style quotient too, but Prakash Raj will win you over once again", "image_link":"https://cdn.dnaindia.com/sites/default/files/styles/third/public/2019/11/22/882305-sarileru-neekevvaru-teaser.jpg" }"""

l = json.loads(j)
l['image_link'] = l['image_link'].replace('https://cdn.dnaindia.com', 'http://localhost')
print(json.dumps(l))
