使用Python SDK的Azure存储错误 [英] Azure storage error using Python SDK

问题描述

我已将适用于python的Azure SDK下载到我的Ubuntu(工具版本0.8.16).而且我正在尝试运行此代码

I've download Azure SDK for python to my Ubuntu (Tool version 0.8.16). And i'm trying to run this code

from azure.storage import BlobService
blob_service = BlobService(account_name='Real_Name', account_key='Real_Key')
blob_service.create_container('mycontainer')
blob_service.create_container('mycontainer', x_ms_blob_public_access='container') 

blob_service.put_block_blob_from_path(
    'mycontainer',
    'myblob',
    'sunset.png',
    x_ms_blob_content_type='image/png'
)

我已将其保存在Test.py下，并且尝试使用

I've saved it under Test.py and i'm trying to run it with

python Test.py

在终端中，我收到此错误

in terminal and i get this error

如何解决此问题，我做对了吗?

How to fix this, and am i do everything right?

谢谢

推荐答案

如错误中所述:

请求日期标头太旧:"2015年3月24日星期二，格林尼治标准时间"

Request date header too old: 'Tue, 24 Mar 2015 09:06:59 GMT'

如果计算机上的日期/时间(以UTC为单位)与Azure存储服务器上的日期/时间之间的差异超过15-20分钟(您的计算机的日期/时间晚于Azure的日期/时间)，则会收到此错误.

You will get this error if difference between the date/time on your computer (in UTC) and date/time on Azure Storage Server is more than 15-20 minutes (your computer's date/time is behind that of Azure).

更新

基本上，发生的情况是，将请求发送到Azure存储服务(例如，创建容器)时，SDK会获取计算机的本地日期/时间，将其转换为UTC，然后将其与请求一起发送到Azure(如日期或x-ms-date的请求标头).收到请求后，Azure存储服务会将该日期/时间与其日期/时间进行比较，如果两者之间的差异超过15-20分钟(您的时钟落后)，则Azure存储服务会引发您得到的错误.这样做是一种安全措施，以防万一有人抓住您的请求而无法一遍又一遍地重播该请求.

Essentially what happens is that when a request is sent to Azure Storage Service (e.g. create container) the SDK takes the local date/time of your computer, converts it into UTC and then sends it to Azure along with the request (as a request header either date or x-ms-date). Upon receiving the request, among other things Azure Storage service compares this date/time with its date/time and if the difference is more than 15-20 minutes (your clock is behind), Azure Storage service throws the error you're getting. This is done as a security measure so that in case somebody got hold of your request can't replay the request over and over again.
