Question

通过API，我收到json输出，而不是将所有输出写入分析中，我只希望数据具有“ true”值。

原始json数据示例：

with open('C:\\output.json', 'w') as outfile:
   for item in data["scans"]:
      if 'item["detected"] === true
         json.dump(data)

Python代码

scans:
    Scanner2:
       detected: true
       version: "2.2.2.2"
       result: "trojan"
       update: "23142551"

所需的输出

import requests


url = '<url>'
params = {'apikey': <key>, 'resource': '<value>'}
response = requests.get(url, params=params)

result = []
with open('C:\\output.json', 'w') as outfile:
  data = response.json()
  for i in data['scans']:
    if (i['detected']=='true'):         // error thrown here
      result.append(i)                  // TypeError: string indices must be integers


print(result)

这绝不可行，我也不知道JSON，但我必须证明我尝试了大声笑。

谢谢！

Answer 1

result =[]
with open('C:\\output.json', 'w') as outfile:
  data = json.load(outfile)
  for i in data['scans']:
    if i['detected']=='true':
      result.append(i) 

print(result)

您的原始数据json看起来不像json（查找json的样子）。但是假设它被错误地复制，下面的字典理解将适用于json：

data = response.json()

with open('C:\\output.json', 'w') as outfile:
    result = {k: v for k, v in data['scans'].items() if v['detected']}
    outfile.write(json.dumps(result))

遍历json并仅返回true元素
