Question

我正在处理请求，而且我被困了，因为我正在改变我的来源。事情是，当我向网站请求对象时，它返回以下json对象：

[
{
"directory":"ca\/48",
"hash":"ca4860af9e3be43b1d23b823af607be4",
"height":1839,
"id":3461818,
"image":"ca4860af9e3be43b1d23b823af607be4.jpg",
"change":1480968006,
"owner":"danbooru",
"parent_id":null,
"rating":"s",
"sample":true,
"sample_height":1398,
"sample_width":850,
"score":0,
"tags":"1girl breasts cape cleavage defense_of_the_ancients dota_2 green_eyes highres lyralei medium_breasts parted_lips pauldrons red_hair smile solo splashbrush thick_thighs thighs toes",
"width":1118,
 "file_url":"http:\/\/gelbooru.com\/images\/ca\/48\/ca4860af9e3be43b1d23b823af607be4.jpg"
}
]

我想更改"file_url"

中的"http:\/\/gelbooru.com\/images\/ca\/48\/ca4860af9e3be43b1d23b823af607be4.jpg"值

到

"http://gelbooru.com/images/ca/48/ca4860af9e3be43b1d23b823af607be4.jpg" 所以我可以通过在我的程序构建器上调用它来完全使用该网站。我怎么做？在此先感谢。

requests可以自动将JSON数据转换为python词典/列表

r = request.get(...)

data = r.json()

然后你有权访问

print( data[0]['file_url'] )

您将看到没有\/，因为它已转换为正确的文字。

标准json模块的示例，内部由requests使用。

text = '''[
{
"directory":"ca\/48",
"hash":"ca4860af9e3be43b1d23b823af607be4",
"height":1839,
"id":3461818,
"image":"ca4860af9e3be43b1d23b823af607be4.jpg",
"change":1480968006,
"owner":"danbooru",
"parent_id":null,
"rating":"s",
"sample":true,
"sample_height":1398,
"sample_width":850,
"score":0,
"tags":"1girl breasts cape cleavage defense_of_the_ancients dota_2 green_eyes highres lyralei medium_breasts parted_lips pauldrons red_hair smile solo splashbrush thick_thighs thighs toes",
"width":1118,
 "file_url":"http:\/\/gelbooru.com\/images\/ca\/48\/ca4860af9e3be43b1d23b823af607be4.jpg"
}
]'''

import json

data = json.loads(text)

print( data[0]['file_url'] )

如何将这个json对象解析为Python？
