TypeError：'Response'对象没有属性'__getitem__'

I am trying to get a value from a response object in a dictionary, but I keep running into this error, am I wrong in thinking you __getitem__ is more commonly used for indexing in classes?

我试图从字典中的响应对象中获取值，但是我一直遇到这个错误，我认为__getitem__更常用于类中的索引是错误的吗？

Here is the code:

这是代码：

import json
import requests
from requests.auth import HTTPBasicAuth

url = "http://public.coindaddy.io:4000/api/"
headers = {'content-type': 'application/json'}
auth = HTTPBasicAuth('rpc', '1234')

payload = {
  "method": "get_running_info",
  "params": {},
  "jsonrpc": "2.0",
  "id": 0,
}

response = requests.post(url, data=json.dumps(payload), headers=headers,   auth=auth)


print("respone is: ", response['result'])

The response object is not a dictionary, you cannot use indexing on it.

响应对象不是字典，您不能对其使用索引。

If the API returns a JSON response, you need to use the response.json() method to decode it to a Python object:

如果API返回JSON响应，则需要使用response.json（）方法将其解码为Python对象：

data = response.json()
print("respone is: ", data['result'])

Note that you don't have to encode the request JSON data either; you could just use the json argument to the request.post() method here; this also sets the Content-Type header for you:

请注意，您不必对请求JSON数据进行编码;你可以在这里使用json参数到request.post（）方法;这也为您设置Content-Type标头：

response = requests.post(url, json=payload, auth=auth)

Last but not least, if the API uses JSONRPC as the protocol, you could use the jsonrpc-requests project to proxy method calls for you:

最后但并非最不重要的是，如果API使用JSONRPC作为协议，您可以使用jsonrpc-requests项目代理方法调用：

from jsonrpc_requests import Server

url = "http://public.coindaddy.io:4000/api/"
server = Server(url, auth=('rpc', '1234'))

result = server.get_running_info()

Just change your source code a bit like this

只需更改源代码即可

response = requests.post(url, json=json.dumps(payload), headers=headers, auth=auth).json()

response = requests.post（url，json = json.dumps（payload），headers = headers，auth = auth）.json（）

print("respone is: ", response['result'].encode('utf-8'))

print（“respone is：”，response ['result']。encode（'utf-8'））

It's true that response object alone can't be indexed instead for that purpose you need to return info in json format (in order parse response information ) which you can do so using json() and Here in order to get proper string you must encode it with utf-8 (other wise your output will be something like this -u'LikeThis)

确实单独的响应对象不能被索引而不是为了这个目的你需要以json格式返回信息（按顺序解析响应信息），你可以使用json（）来实现这一点，为了获得正确的字符串，你必须编码它与utf-8（其他明智的你的输出将是这样的东西-u'LikeThis）
