"字符串索引必须是整数"

下面是我导入的JSON FIle:-。

  "project_id": "Some Data",
  "private_key_id": "Some Data",
  "private_key": "Some Data",
  "client_email": "Some Data",
  "client_id": "Some Data",
  "auth_uri": "Some Data",
  "token_uri": "Some Data",
  "auth_provider_x509_cert_url": "Some Data",
  "client_x509_cert_url": "Some Data"
  }

你应该首先打开文件，并将打开的文件传入 json.load(file)

import json
# opening the json file
json_file = open('1.json','r+')

json_object = json.load(json_file)

print(json_object["client_id"])


Output:
Some Data

用于循环处理以数字命名的json文件。

import json
# opening the json file
# files named as 1.json to 3.json will do this
for i in range(1,4):
    json_file = open(str(i)+'.json','r+')

    json_object = json.load(json_file)

    print(json_object["client_id"])
