如何为 Azure 表存储 REST 请求生成 SharedKeyLite

问题描述

我正在尝试使用 Postman 调用 Azure 表存储，但不断收到:

I'm trying to call Azure Table Storage using Postman but keep getting :

服务器未能验证请求.确保值包括签名在内的授权标头格式正确.

我在 Postman 中用于 pre-call 脚本的代码如下:

The code I am using for the pre-call script in Postman is as follows:

var storageAccount = "**mystorageaccount**";
var accountKey = "**mystoragekey**";

var date = new Date();
var UTCstring = date.toUTCString();

var data = date + "
" + "/**mystorageaccount**/**mytable**"

var encodedData = unescape(encodeURIComponent(data));

var hash = CryptoJS.HmacSHA256(encodedData, accountKey);
var signature = hash.toString(CryptoJS.enc.Base64);

var auth = "SharedKeyLite " + storageAccount + ":" + signature;

postman.setEnvironmentVariable("auth", auth);
postman.setEnvironmentVariable("date", UTCstring);

Postman中的headers如下:

The headers in Postman are as follows:

Authorization : {{auth}}
date : {{date}}
version : 2015-12-11

我猜这个问题可能出在数据变量上，但没有什么想法.

I am guessing the issue may be with the data variable, but running out of ideas.

推荐答案

您收到此错误的原因是您没有将帐户密钥转换为缓冲区.请更改以下代码行:

The reason you're getting this error is because you're not converting your account key to a buffer. Please change the following line of code:

var hash = CryptoJS.HmacSHA256(encodedData, accountKey);

到

var hash = CryptoJS.HmacSHA256(encodedData, Buffer.from(accountKey, 'base64'));

你不应该得到错误.

更新

我也遇到了同样的错误.请尝试以下代码:

I also got the same error. Please try the following code:

var storageAccount = "**mystorageaccount**";
var accountKey = "**mystoragekey**";

var date = new Date();
var UTCstring = date.toUTCString();

var data = UTCstring + "
" + "/**mystorageaccount**/**mytable**"

var encodedData = unescape(encodeURIComponent(data));

var hash = CryptoJS.HmacSHA256(encodedData, CryptoJS.enc.Base64.parse(accountKey));
var signature = hash.toString(CryptoJS.enc.Base64);

var auth = "SharedKeyLite " + storageAccount + ":" + signature;

postman.setEnvironmentVariable("auth", auth);
postman.setEnvironmentVariable("date", UTCstring);

我刚刚尝试了上面的代码，并且能够在我的表中列出实体.

I just tried the code above and was able to list entities in my table.
