[Azure]用REST API列出Storage Account下的Container

照著MSDN試了半天，終於發現順序還是很重要的。

假設我的Storage Account是slakchiprod，則我的request URL要是http:/slakchiprod.blob.core.windows.net/?comp=list

然後以下面這段程式碼來取得slakchiprod下的所有container。

            var utcTime = DateTime.UtcNow.ToString("R");
            var xmsversion = "2011-08-18";
            HttpWebRequest req = (HttpWebRequest)WebRequest.Create(new Uri(URL));
            req.Method = "GET";
            //下面這兩個Header的順序不能改...
            req.Headers["x-ms-version"] = xmsversion; 
            req.Headers["x-ms-date"] = utcTime;
            string stringToSign = "GET\n" +
                    "\n" +  /*Content-Encoding*/
                    "\n" +  /*Content-Language*/
                    "\n" +  /*Content-Length*/
                    "\n" +  /*Content-MD5*/
                    "\n" +  /*Content-Type*/
                    "\n" +  /*Date*/
                    "\n" +  /*If-Modified-Since */
                    "\n" +  /*If-Match*/
                    "\n" +  /*If-None-Match*/
                    "\n" +  /*If-Unmodified-Since*/
                    "\n" +  /*Range*/
                    "x-ms-date:{0}\n" + 
                    "x-ms-version:{1}\n" +
                    "/{2}/\n" + //URL
                    "{3}"; //Param
            stringToSign = string.Format(stringToSign, 
                                                        utcTime,
                                                        xmsversion,
                                                        storageAcct,/*slakchiprod*/
                                                        "comp:list");
           
            HMACSHA256 crypt = newHMACSHA256(Convert.FromBase64String(key));
            var buffer = crypt.ComputeHash(.UTF8.GetBytes(stringToSign));
            var result = Convert.ToBase64String(buffer);
            req.Headers["Authorization"] = "SharedKey " + string.Format("{0}:{1}", storageAcct, result);
            
           req.GetResponse();//取得回應
