设置环境变量问题

Question

我的 google api 测试出现身份验证错误，设置环境变量的代码单独工作，但是当与 google 测试代码结合使用时授权失败。我还能够通过运行 shell 中的 EXPORT 命令使测试代码正常工作。为了方便起见，我希望能够在我的脚本中设置身份验证。

 #This program will test the google speech api
 #while setting the environmental variable for the
 #authentication .json file and then authenticating

 import os

 # Imports the Google Cloud client library
 from google.cloud import language
 from google.cloud.language import enums
 from google.cloud.language import types

 # My code sets the authentication env variable
 os.environ['GOOGLE_APPLICATION_CREDENTIALS'] = str('home/kyle/Security/test.json')

 # Instantiates a client
 client = language.LanguageServiceClient()

 # The text to analyze
 text = u'Hello, world!'
 document = types.Document(
     content=text,
     type=enums.Document.Type.PLAIN_TEXT)

 # Detects the sentiment of the text
 sentiment = client.analyze_sentiment(document=document).document_sentiment

 print('Text: {}'.format(text))
 print('Sentiment: {}, {}'.format(sentiment.score, sentiment.magnitude))

错误：

   File "/home/kyle/python projects/googleSpeech/test/venv/lib/python3.5/site-packages/google/auth/_default.py", line 142, in _get_explicit_environ_credentials
os.environ[environment_vars.CREDENTIALS])
   File "/home/kyle/python projects/googleSpeech/test/venv/lib/python3.5/site-packages/google/auth/_default.py", line 67, in _load_credentials_from_file
'File {} was not found.'.format(filename))
 google.auth.exceptions.DefaultCredentialsError: File home/kyle/Security/test.json was not found.

EDIT 现在导出 json 文件不起作用我运行此代码用于测试读取 .json 文件

 fd = open(‘/home/kyle/Security/test.json’)
 dat = fd.read()
 fd.close()

结果：

 SyntaxError: Non-ASCII character '\xe2' in file testRead.py on line 2, but no encoding declared; see http://python.org/dev/peps/pep-0263/ for details

Answer 1

仔细观察，我认为可能是这一行：

os.environ['GOOGLE_APPLICATION_CREDENTIALS'] = str('home/kyle/Security/test.json')

在home/kyle/....前面加一个/，这样就是/home/kyle/...

Answer 2

该问题要求我从 api 控制台重新生成一个新的 json 密钥，并获得项目所有者的许可，现在可以正常工作，无需更改代码
