【问题描述】:
我在第一次调用 Azure 存储 REST API 时被困了一整天。 Postman 的回复显示是 Azure 身份验证出错,但我不知道是什么问题。
这是发送 Azure 存储 REST API 的浏览器脚本:
function azureListContainers() {
var key = "key-copied-from-azure-storage-account";
var strTime = (new Date()).toUTCString();
var strToSign = 'GET\n\n\n\nx-ms-date:' + strTime + '\nx-ms-version:2015-12-11\n/myaccount/?comp=list';
var hash = CryptoJS.HmacSHA256(strToSign, key);
var hashInBase64 = CryptoJS.enc.Base64.stringify(hash);
var auth = "SharedKeyLite myaccount:"+hashInBase64;
console.log(strToSign);
console.log(auth);
console.log(strTime);
$.ajax({
type: "GET",
beforeSend: function (request)
{
request.setRequestHeader("Authorization", auth);
request.setRequestHeader("x-ms-date", strTime);
request.setRequestHeader("x-ms-version", "2015-12-11");
},
url: "https://myaccount.blob.core.windows.net/?comp=list",
processData: false,
success: function(msg) {
console.log(msg);
}
});
}
Chrome 开发者工具无故返回 No 'Access-Control-Allow-Origin' 标头,所以我复制了 var auth 和 var strTime 的内容,使用 Postman 工具创建了相同的请求:
[Command]
GET https://myaccount.blob.core.windows.net/?comp=list
[Headers]
Authorization:SharedKeyLite myaccount:Z9/kY/D+osJHHz3is+8yJRqhj09VUlr5n+PlePUa8Lk=
x-ms-date:Tue, 09 Aug 2016 10:30:49 GMT
x-ms-version:2015-12-11
[Response Body]
<?xml version="1.0" encoding="utf-8"?>
<Error>
<Code>AuthenticationFailed</Code>
<Message>Server failed to authenticate the request. Make sure the value of Authorization header is formed correctly including the signature.
RequestId:9be3d595-0001-0012-4929-f2fde2000000
Time:2016-08-09T10:31:52.6542965Z</Message>
<AuthenticationErrorDetail>The MAC signature found in the HTTP request 'Z9/kY/D+osJHHz3is+8yJRqhj09VUlr5n+PlePUa8Lk=' is not the same as any computed signature. Server used following string to sign: 'GET
x-ms-date:Tue, 09 Aug 2016 10:30:49 GMT
x-ms-version:2015-12-11
/myaccount/?comp=list'.</AuthenticationErrorDetail>
</Error>
区分这两个字符串后,我相信我的脚本中的var strToSign 与Azure 用于签名的字符串相同。但仍然存在身份验证错误。请帮忙指出问题所在。
