Azure Table 通过 javascript 存储验证 REST 调用
Azure Table Storage Authenticate REST call through javascript
我正在尝试使用 javascript 对我的 Azure Table 进行 REST 调用,但我发现很难对调用进行身份验证。
我正在使用 javascript 的那个片段(我知道日期必须最多 15 分钟,而且我不打算使用 javascript 中的实际密钥!)
$(document).ready(function(){
$("button").click(function(){
var dateTimeInUtc = 'Fri, 12 Feb 2016 12:14:00 GMT';
var version = '2015-04-05';
var key = 'JEwMjqFD1ng8vIaECmRw8eQysiIvH08nF/jPKPYaNGumgxtKIjltX8bte5sKN6SNyw09s=='; // not an actuall key
var stringToSign = 'GET\n\n\nFri, 12 Feb 2016 12:14:00 GMT\n/myaccount/mytable(PartitionKey=\'first_partition\', RowKey=\'1235\')';
var signature = CryptoJS.enc.Base64.stringify(CryptoJS.HmacSHA256(CryptoJS.enc.Utf8.parse(stringToSign), CryptoJS.enc.Base64.parse(key)));
$.ajax({
url:'https://myaccount.table.core.windows.net/mytable(PartitionKey=\'first_partition\', RowKey=\'1235\')',
type: 'GET',
success: function (data) {
console.log('well done');
},
beforeSend: function (xhr) {
xhr.setRequestHeader('Authorization', "SharedKey " + "myaccount" + ":" + signature);
xhr.setRequestHeader('x-ms-date', dateTimeInUtc);
xhr.setRequestHeader('x-ms-version', version);
},
error: function (rcvData) {
console.log(rcvData);
}
});
});
});
我得到了什么
403 (Server failed to authenticate the request. Make sure the value of Authorization header is formed correctly including the signature.)
你有没有发现明显的错误?我是否遗漏了签名中的某些内容?
基于documentation for creating authorization header
,创建要签名的字符串:
- Beginning with an empty string (""), append a forward slash (/), followed by the name of the account that owns the resource being
accessed.
- Append the resource's encoded URI path, without any query parameters.
- Append a new-line character (\n) after the resource name.
但是在您的代码中,您没有包含 (PartitionKey=\'first_partition\', RowKey=\'1235\')
应该包含的内容。
你能试试下面的方法吗:
var stringToSign = 'GET\n\n\nFri, 12 Feb 2016 12:14:00 GMT\n/htirawdata/htirawdata(PartitionKey=\'first_partition\', RowKey=\'1235\')';
您构建的待签名字符串必须与通过网络传输的 URL 完全一致,包括 URL 中不允许的百分比编码字符。在这种情况下,URL 中的 space 字符将通过网络进行百分比编码,因此它必须在待签名字符串中进行百分比编码。
来自MSDN page:
Any portion of the CanonicalizedResource string that is derived from the resource's URI should be encoded exactly as it is in the URI.
