使用 Python 从 json 文件中读取特定值

Question

I am getting a JSON file from a curl request and I want to read a specific value from it. Suppose that I have a JSON file, like the following one. How can I insert the "result_count" value into a variable?

Currently, after getting the response from curl, I am writing the JSON objects into a txt file like this.

json_response = connect_to_endpoint(url, headers)

f.write(json.dumps(json_response, indent=4, sort_keys=True))

Answer 1

Your json_response isn't a JSON content (JSON is a formatted string), but a python dict , you can access it using the keys

res_count = json_response['meta']['result_count']

Answer 2

Use the json module from the python standard library.
data itself is just a python dictionary, and can be accessed as such.

import json

with open('path/to/file/filename.json') as f:
  data = json.load(f)

result_count = data['meta']['result_count']

Answer 3

you can parse a JSON string using json.loads() method in json module.

response = connect_to_endpoint(url, headers)
json_response = json.load(response)

after that you can extract an element with specify element name in Brackets

result_count = ['meta']['result_count']
