如何使用 Python 从文件中读取 API 身份验证数据？

Question

从文件中读取 API 密钥时，我遇到了“错误身份验证”错误，如下所示：

#!/usr/local/bin/python
import tweepy

#open a file called "keys" with keys and tokens for Twitter separated by newlines
keyFile = open('keys', 'r')
consumer_key = keyFile.readline()
consumer_secret = keyFile.readline()
access_token = keyFile.readline()
access_token_secret = keyFile.readline()
keyFile.close()
print "consumer key: " + consumer_key
print "consumer secret: " + consumer_secret
print "access token: " + access_token
print "access token secret: " + access_token_secret

auth = tweepy.OAuthHandler(consumer_key, consumer_secret)
auth.set_access_token(access_token, access_token_secret)

如果我手动设置密钥（例如使用 ）consumer_key = "xxx"，则效果很好。关于为什么从文件读取时不起作用的任何提示？谢谢。

事实证明 Python 也在读取换行符。解决方案是使用 rstrip() 去除隐藏字符：

consumer_key = keyFile.readline().rstrip()
