使用非 mime message.get 方法，我拉出正文/数据并尝试对其进行解码，以便简单地以英文显示消息。我遇到的问题是某些消息可以正常解码，然后突然出现错误的填充问题。我尝试替换 + 和 / 无济于事。
为什么会发生这种情况，我该如何解决？
这是我的 messages.get 方法：
try:
message = service.users().messages().get(userId=user_id, id=msg_id).execute()
# Pull Raw Message Body from Response
message_raw = message['payload']['parts'][0]['body']['data']
# Decode the raw message
message_decoded = base64.b64decode(message_raw)
# Print the messages
print message_decoded
更新
服务
gmail_service = build('gmail', 'v1', http=http)
回溯错误
