问题描述

我使用的是最新的Azure SDK存储模拟器。我试图登录到我的BLOB的请求。当我运行低于code我得到权威性的错误。

我无法弄清楚什么是错的,虽然我已经检查好几次了code符合的Azure SDK BLOB访问规格。

下面是控制台输出:

  GETX-MS-日期:孙老师,2012年9月23日4时04分07秒GMT
/ devstoreaccount1 /鸣叫/?补偿=名单
SharedKey devstoreaccount1:Hx3Pm9knGwCb4Hs9ftBX / + QlX0kCGGlUOX5g6JHZ9Kw =
服务器无法验证请求。确保授权头的值是正确形成,包括签名。

下面是code:

 }

从拉夫和Smarx反馈后,这里是code,我还是得到同样的错误。你能告诉我一些code?这是很难以其他方式理解。

解决方案

修改在哪里拉夫的回答去? :-)我相信他已经回答了,并提到,你似乎是构建一个共享密钥精简版的签名,因此应在授权头使用SharedKeyLite。


我觉得拉夫是正确的,他的回答,但我注意到另外三个问题:


  1. 您似乎正在为 HTTP调用://本地主机/ devstoreaccount1 ,但你计算为 HTTP签名://本地主机/ devstoreaccount1 /鸣叫/?补偿=列表。确保网址匹配。

  2. 对于存储模拟器,我想你的规范化的资源实际上应该是 / devstoreaccount1 / devstoreaccount1 /鸣叫/?补偿=列表。 (请注意,帐户名称的重复。)它一般应 /<帐户> /<路径> ,并为存储模拟器,帐户名显示出来路径。

  3. 哪里 X-MS-版本头?我的相信的那是必需的。

更新这里的一些工作code有两种方法,一种使用共享密钥,并使用共享密钥精简版之一。希望这将清除的东西了。注意,要使用存储模拟器,你要切换URL回本地主机:10000 / devstoreaccount1 。签名code还是应该在模拟器上工作,但我没有测试它。该Base64编码库从这里走过:的http://commons.apache.org/$c$cc/apidocs/org/apache/commons/$c$cc/binary/Base64.html.

I am using the latest Azure SDK Storage emulator. I am trying to sign a request to my blob. When I run the below code I am getting auth error.

I can't figure out what is wrong, although I have checked several times that the code conforms to the Azure SDK blob access specs.

Here is the console output:

GET



x-ms-date:Sun, 23 Sep 2012 04:04:07 GMT
/devstoreaccount1/tweet/?comp=list
SharedKey devstoreaccount1:Hx3Pm9knGwCb4Hs9ftBX/+QlX0kCGGlUOX5g6JHZ9Kw=
Server failed to authenticate the request. Make sure the value of Authorization header is formed correctly including the signature.

Here is the code:

public static void signRequest(HttpURLConnection request, String account, String key) throws Exception
{
    SimpleDateFormat fmt = new SimpleDateFormat("EEE, dd MMM yyyy HH:mm:ss");
    fmt.setTimeZone(TimeZone.getTimeZone("GMT"));
    String date = fmt.format(Calendar.getInstance().getTime()) + " GMT";

    StringBuilder sb = new StringBuilder();
    sb.append("GET\n"); // method
    sb.append('\n'); // md5 (optional)
    sb.append('\n'); // content type
    sb.append('\n'); // legacy date
    sb.append("x-ms-date:" + date + '\n'); // headers
    sb.append(request.getURL().getPath() + "/tweet/?comp=list"); // resource TODO: "?comp=..." if present

    System.out.println(sb.toString());
    Mac mac = Mac.getInstance("HmacSHA256");
    mac.init(new SecretKeySpec(Base64.decode(key), "HmacSHA256"));
    String authKey = new String(Base64.encode(mac.doFinal(sb.toString().getBytes("UTF-8"))));
    String auth = "SharedKey " + account + ":" + authKey;
    request.setRequestProperty("x-ms-date", date);
    request.setRequestProperty("Authorization", auth);
    request.setRequestMethod("GET");
    System.out.println(auth);
}

{
     String account = "devstoreaccount1";
     String key = "Eby8vdM02xNOcqFlqUwJPLlmEtlCDXJ1OUzFT50uSRZ6IFsuFq2UVErCz4I6tq/K1SZFPTOtr/KBHBeksoGMGw==";
     HttpURLConnection connection = (HttpURLConnection) (new URL("http://localhost:10000/devstoreaccount1")).openConnection();
     signRequest(connection, account, key);
     connection.connect();
     System.out.println(connection.getResponseMessage());
 }

After feedback from Gaurav and Smarx, here is the code, I still get the same error. Can you show me some code? It is hard to understand otherwise.

    public static void sign(HttpURLConnection request, String account, String key, String url) throws Exception
    {
        SimpleDateFormat fmt = new SimpleDateFormat("EEE, dd MMM yyyy HH:mm:ss");
        fmt.setTimeZone(TimeZone.getTimeZone("GMT"));
        String date = fmt.format(Calendar.getInstance().getTime()) + " GMT";

        StringBuilder sb = new StringBuilder();
        sb.append("GET\n"); // method
        sb.append('\n'); // md5 (optional)
        sb.append('\n'); // content type
        sb.append('\n'); // legacy date
        sb.append("x-ms-date:" + date + '\n'); // headers
        sb.append("x-ms-version:2009-09-19\n"); // headers
        sb.append("/devstoreaccount1/devstoreaccount1/\n$maxresults:1\ncomp:list\nrestype:container"); // resource TODO: "?comp=..." if present

        System.out.println(sb.toString());
        Mac mac = Mac.getInstance("HmacSHA256");
        mac.init(new SecretKeySpec(Base64.decode(key), "HmacSHA256"));
        String authKey = new String(Base64.encode(mac.doFinal(sb.toString().getBytes("UTF-8"))));
        String auth = "SharedKeyLite " + account + ":" + authKey;
        request.setRequestProperty("x-ms-date", date);
        request.setRequestProperty("Authorization", auth);
        request.setRequestMethod("GET");
        System.out.println(auth);
    }

    public static void main(String args[]) throws Exception
    {

        String account = "devstoreaccount1";
        String key = "Eby8vdM02xNOcqFlqUwJPLlmEtlCDXJ1OUzFT50uSRZ6IFsuFq2UVErCz4I6tq/K1SZFPTOtr/KBHBeksoGMGw==";
        String url = "http://127.0.0.1:10000/devstoreaccount1/?restype=container&comp=list&$maxresults=1";
        HttpURLConnection connection = (HttpURLConnection) (new URL(url)).openConnection();
        sign(connection, account, key, url);
        connection.connect();

    }

解决方案

EDIT Where did Gaurav's answer go? :-) I believe he already answered and mentioned that you appear to be constructing a Shared Key Lite signature and should thus use "SharedKeyLite" in your authorization header.


I think Gaurav is right in his answer, but I noticed three other issues:

  1. You seem to be making a call to http://localhost/devstoreaccount1, but you're computing a signature for http://localhost/devstoreaccount1/tweet/?comp=list. Make sure the URLs match up.
  2. For the storage emulator, I think your canonicalized resource should actually be /devstoreaccount1/devstoreaccount1/tweet/?comp=list. (Note the repetition of the account name.) It should generally be /<account>/<path>, and for the storage emulator, the account name shows up in the path.
  3. Where's the x-ms-version header? I believe that's required.

UPDATE Here's some working code with two methods, one that uses Shared Key and one that uses Shared Key Lite. Hopefully this clears things up. Note that to use the storage emulator, you'll want to switch the URL back to localhost:10000/devstoreaccount1. The signature code should still work for the emulator, but I haven't tested it. The Base64 library came from here: http://commons.apache.org/codec/apidocs/org/apache/commons/codec/binary/Base64.html.
