嗨,我遇到此错误消息的问题.我是Python的新手,这个Python2和Python3很麻烦.我不知道该怎么做,错误信息如下所示.

Using Ticker: AAPL
    Traceback (most recent call last):
      File "realtime.py", line 18, in <module>
        r=requests.get(auth_url, headers={"Authorization": "Basic %s" % base64.b64encode(os.environ['INTRINIO_USER'] + ":" + os.environ['INTRINIO_PASSWORD'])})
      File "C:\Users\User\AppData\Local\Programs\Python\Python36-32\lib\base64.py", line 58, in b64encode
        encoded = binascii.b2a_base64(s, newline=False)
    TypeError: a bytes-like object is required, not 'str'

我使用的代码如下所示.

import websocket
import _thread
import time
import requests
import base64
import json
import sys
import os
from requests.auth import HTTPBasicAuth

try:
    print ("Using Ticker: " + str(sys.argv[1]))
except:
    print ("Please include ticker as first argument")
    sys.exit() …

我收到一条错误消息，但不知道如何继续，错误消息显示在下面。我已经下载了它运行所需的所有工具，但密钥似乎有问题。我已经正确输入了它们，但是为了保持我的帐户的私密性，我已隐藏帐户用户名和密码。提前致谢

Using Ticker: AAPL

  File "C:\Users\User\AppData\Local\Programs\Python\Python36-32\lib\os.py", line 669, in __getitem__

这是我正在使用的代码，第 18 行是“r=requests.get(auth_url, headers...”
