如何使用REST API（ARM）访问Azure存储表

Question

通过查看以下链接，不清楚签名应该包含什么或者如何形成规范字符串以创建可使用HMAC-SH256算法加密的签名。

https://msdn.microsoft.com/en-us/library/azure/dd179428.aspx

我使用以下网址

GET https://mystorageaccount.table.core.windows.net/Tables

页眉：

Authorization SharedKeyLite mystorrageaccount:<<encrypted signature>> 
x-ms-date Thu 28 Jul 2016 11:19:33 GMT 

获得以下错误：

Server failed to authenticate the request. Make sure the value of Authorization header is formed correctly including the signature.

@Prit，请参阅下面的代码以生成表存储的共享密钥文件作为参考。

import java.security.InvalidKeyException; 
import java.security.NoSuchAlgorithmException; 
import java.text.SimpleDateFormat; 
import java.util.Calendar; 
import java.util.Locale; 
import java.util.TimeZone; 

import javax.crypto.Mac; 
import javax.crypto.spec.SecretKeySpec; 

import org.apache.commons.codec.binary.Base64; 

String secret = "<storage-account-key>"; 
// Date for string to sign 
Calendar calendar = Calendar.getInstance(); 
SimpleDateFormat sdf = new SimpleDateFormat("EEE, d MMM yyyy HH:mm:ss 'GMT'", Locale.US); 
sdf.setTimeZone(TimeZone.getTimeZone("GMT")); 
String date = sdf.format(calendar.getTime()); 
// canonicalizedResource, such as "/testaccount1/Tables" 
String canonicalizedResource = "<Canonicalized-Resource>"; 
String stringToSign = date + "\n" + canonicalizedResource; 
System.out.println(stringToSign); 
// HMAC-SHA@%^ 
Mac sha256HMAC = Mac.getInstance("HmacSHA256"); 
SecretKeySpec secretKey = new SecretKeySpec(secret.getBytes(), "HmacSHA256"); 
sha256HMAC.init(secretKey); 
String hash = Base64.encodeBase64String(sha256HMAC.doFinal(stringToSign.getBytes())); 
System.out.println(hash);
