Azure 存储 table REST Api 调用 - 无效 Header

Question

我正在尝试调用 REST API 来查看 Azure 存储 table 的内容。希望我已经正确地形成了 Authorization header 值并且我得到了以下错误。请纠正我在以下请求中遗漏的地方（来自 REST 客户端应用程序）。

{
  "method": "GET",
  "transformRequest": [
    null
  ],
  "transformResponse": [
    null
  ],
  "url": "https://#####.table.core.windows.net/testDB",
  "headers": {
    "x-ms-date": "Thu, 28 Jun 2018 08:39:05 GMT",
    "x-ms-version": "2018-06-28",
    "Accept": "application/json;odata=nometadata",
    "Authorization": "SharedKeyLite #####:########"
  },
  "data": "",
  "timeout": {}
}

这是我的回复Headers：

{
  "x-ms-request-id": "3fc23b14-2002-0037-04bc-0e9e56000000",
  "date": "Thu, 28 Jun 2018 08:46:39 GMT",
  "server": "Microsoft-HTTPAPI/2.0",
  "content-length": "371",
  "content-type": "application/xml",
  "status": 400
}

和回应Body

<?xml version="1.0" encoding="utf-8" standalone="yes"?>
<error xmlns="http://schemas.microsoft.com/ado/2007/08/dataservices/metadata">
  <code>InvalidHeaderValue</code>
  <message xml:lang="en-US">The value for one of the HTTP headers is not in the correct format.

</error>

这里是JAVA代码，我用来生成SignatureString

    private void printHash()
    {
//        https://mytestaccount.table.core.windows.net/testDB: this is the url form Azure portal displaying next to table
        String secret = "I Updated my key here";
// 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 = "/testDB";
        String stringToSign = date + "\n" + canonicalizedResource;
        System.out.println(stringToSign);
// HMAC-SHA@%^
        Mac sha256HMAC = null;
        try {
            sha256HMAC = Mac.getInstance("HmacSHA256");
            SecretKeySpec secretKey = new SecretKeySpec(secret.getBytes(), "HmacSHA256");
            sha256HMAC.init(secretKey);
            String hash = Base64.encodeToString(sha256HMAC.doFinal(stringToSign.getBytes()), Base64.DEFAULT);
            System.out.println(hash);
        } catch (NoSuchAlgorithmException e) {
            e.printStackTrace();
        } catch (InvalidKeyException e) {
            e.printStackTrace();
        }
}

四点修正：

x-ms-version 如果您想要获取 application/json;odata=nometadata 的内容，则不是可选的。 x-ms-version 应明确设置为 2013-08-15 或更高版本（最新为 2018-03-28) to support this format. See Json format in table service.
日期格式应为 EEE, dd MMM yyyy HH:mm:ss 'GMT'。两位数字表示日。
canonicalizedResource 应该是 storageAccountName\tableName 就像您的代码备注一样。
要生成SecretKeySpec，SecretKeySpec secretKey = new SecretKeySpec(Base64.decode(secret), "HmacSHA256");因为secret是用Base64编码的。
