如何为Azure表存储REST请求生成SharedKeyLite [英] How to generate SharedKeyLite for Azure Table Storage REST request
问题描述
我正在尝试使用Postman调用Azure Table Storage,但一直保持:
I'm trying to call Azure Table Storage using Postman but keep getting :
服务器无法验证请求.确保的价值授权标头的格式正确,包括签名.
Server failed to authenticate the request. Make sure the value of Authorization header is formed correctly including the signature.
我在Postman中用于预呼叫脚本的代码如下:
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 + "\n" + "/**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中的标题如下:
The headers in Postman are as follows:
Authorization : {{auth}}
date : {{date}}
version : 2015-12-11
我猜想问题可能出在数据变量上,但想法不多了.
I am guessing the issue may be with the data variable, but running out of ideas.
推荐答案
出现此错误的原因是,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'));
而且您不应收到错误消息.
And you should not get the error.
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 + "\n" + "/**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,并能够列出表中的实体.
I just tried the code above and was able to list entities in my table.
