我目前正在尝试从发布请求响应中解析一些数据，并且不断收到此错误：“ TypeError：列表索引必须是整数或切片，而不是str”

Python代码

import requests
import json

count = 0
params = {'var1':'40', 'value':'143', 'itm':'1', 'param':'1'}


req = 'https://www.api.com/api/search'
data = requests.post(req, data = params).json()

print (data['result']['results']['name'])

JSON回应

我做了类似的代码，但这是一个get请求，一切都很好。
