在Python中传递JSON文档

Question

我试图将要编码的策略文档传递给base64。

的政策文件位于~/policy_document

>>> policy = base64.b64encode(policy_document) 

什么我需要在这里做的就是policy_document将它传递为Base64？谢谢。

Answer 1

# First open the file 
# Then read the entire contents into memory 
>>> policy_document = open("/absolute/path/to/policy_document", "r").read() 

# Then base64 encode the contents. 
>>> policy = base64.b64encode(policy_document) 

# If you are using Python 2.7 you can use the with statement 
# to ensure files are cleaned up 
# (See @Niklas' comment) 
>>> with open("/absolute/path/to/policy_document", "r") as fp: 
...  policy_document = fp.read() 
...  policy = base64.b64encode(policy_document) 
# fp will be properly closed

另外，如果你需要它是从当前用户的主文件夹，你可以添加一个调用os.path.expanduser("~/policy_document")

这为我工作：

policy = base64.b64encode(json.JSONEncoder().encode({dict})
