Azure EventHubs REST API 401未经授权

我试图使用curl执行eventhubs restapi,但它不起作用。

卷曲

curl --proxy $PROXY -i -X "GET" "https://management.azure.com/subscriptions/$SUBSCRIPTION_ID/resourceGroups/$RESOURCE_GROUP/providers/Microsoft.EventHub/namespaces/$NAME_SPACE/eventhubs/$EVENTHUB?api-version=2017-04-01" -H "Authorization: $TOKEN"

生成SAS(C#)

var resourceuri = "https://myspacename.servicebus.windows.net/myeventhub";
            var key = "mykey";
            var keyname = "mykeyname";
            TimeSpan sinceEpoch = DateTime.UtcNow - new DateTime(1970, 1, 1);
            var week = 60 * 60 * 24 * 7;
            var expiry = Convert.ToString((int)sinceEpoch.TotalSeconds + week);

            string stringToSign = Uri.EscapeDataString(resourceuri) + "\n" + expiry;
            HMACSHA256 hmac = new HMACSHA256(Encoding.UTF8.GetBytes(key));
            var signature = Convert.ToBase64String(hmac.ComputeHash(Encoding.UTF8.GetBytes(stringToSign)));
            var sasToken = String.Format("SharedAccessSignature sr={0}&sig={1}&se={2}&skn={3}", Uri.EscapeDataString(resourceuri), Uri.EscapeDataString(signature), expiry, keyname);
            return sasToken;

回答

{"error":{"code":"AuthenticationFailedInvalidHeader","message":"Authentication failed. The 'Authorization' header is provided in an invalid format."}}

我参考了这份文件( https://docs.microsoft.com/ja-jp/rest/api/eventhub/Generate-SAS-token?redirectedfrom=MSDN ). 此外,我尝试使用此工具( https://github.com/sandrinodimattia/RedDog/releases/tag/0.2.0.1 )但结果也是一样的。

你有什么想法吗?
