How to make a REST call to an Azure Queue

Question

I am able to make a C# library call to a queue using the SDK. However I am unable to make a REST call to the queue.

How shall I proceed? Any code sample will be appreciated.

Please tell us what have you tried so far and what are the issues you're running into. I'm sure that if you do a proper search you will find lots of code samples in C# where REST API is being consumed instead of using .Net SDK. — Gaurav Mantri, Feb 21 '17 at 07:52
@GauravMantri I tried to do some search, but I am not able to find the ones fitting my requirement.I am very new to azure.Any sample code link will be appreciated — pankaj, Feb 21 '17 at 09:11
Though a bit old but take a look here: https://azurestoragesamples.codeplex.com. This should give you an idea about how to proceed. — Gaurav Mantri, Feb 21 '17 at 09:17
we have shared you some samples, are you able to operate Azure queue via Rest API now? — Fei Han, Mar 01 '17 at 06:06

Firstly, this link lists the REST operations for working with message queues that Azure Storage provides, please check the link to get detailed informations.

Secondly, here is a sample request to create a queue under the given account, you could construct your request like this.

HttpWebRequest req = (HttpWebRequest)WebRequest.Create(string.Format(CultureInfo.InvariantCulture,
"https://{0}.queue.core.windows.net/{1}",
StorageAccount, queuename));

req.Method = "PUT";
req.Headers.Add("Authorization", AuthorizationHeader);
req.Headers.Add("x-ms-date", mxdate);
req.Headers.Add("x-ms-version", storageServiceVersion);
req.ContentLength = 0;

and please refer to the following code and Authentication for the Azure Storage Services to construct the signature string for generating AuthorizationHeader.

string canonicalizedHeaders = string.Format(
    "x-ms-date:{0}\nx-ms-version:{1}",
    mxdate,
    storageServiceVersion);

string canonicalizedResource = string.Format("/{0}/{1}", StorageAccount, queuename);

string stringToSign = string.Format(
"{0}\n\n\n\n\n\n\n\n\n\n\n\n{1}\n{2}",
requestMethod,
canonicalizedHeaders,
canonicalizedResource);

the request looks like this.

There are examples in the official documentation:

Request:  
POST https://myaccount.queue.core.windows.net/messages?visibilitytimeout=30&timeout=30 HTTP/1.1  

Headers:  
x-ms-version: 2011-08-18  
x-ms-date: Tue, 30 Aug 2011 01:03:21 GMT  
Authorization: SharedKey myaccount:sr8rIheJmCd6npMSx7DfAY3L//V3uWvSXOzUBCV9wnk=  
Content-Length: 100  

Body:  
<QueueMessage>  
<MessageText>PHNhbXBsZT5zYW1wbGUgbWVzc2FnZTwvc2FtcGxlPg==</MessageText>  
</QueueMessage>
