在Python中傳遞JSON文檔

Question

我正在嘗試傳遞要編碼為base64的策略文檔。

策略文檔位於~/policy_document

>>> policy = base64.b64encode(policy_document)

我需要做什么才能將policy_document傳遞給base64？ 謝謝。

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

或者，如果您需要它來自當前用戶的主文件夾，則可以添加對os.path.expanduser("~/policy_document")的調用

這為我工作：

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