我想使用http客户端请求从azure存储中获取所有blob容器。 我做了一个样本,但我面临禁止403错误。
我附上了我的代码,
private const string ListofContainersURL = "https://{0}.blob.core.windows.net/?comp=list&maxresults=3"; //https://myaccount.blob.core.windows.net/?comp=list&maxresults=3
public string ListofContainersinBlob()
{
string Requesturl = string.Format(ListofContainersURL, storageAccount );
HttpWebRequest request = (HttpWebRequest)WebRequest.Create(Requesturl);
string now = DateTime.UtcNow.ToString("R");
request.Method = "GET";
request.Headers.Add("x-ms-version", "2015-12-11");
request.Headers.Add("x-ms-date", now);
request.Headers.Add("Authorization", AuthorizationHeader1("GET", now, request, storageAccount, storageKey));
var response = request.GetResponseAsync();
using (HttpWebResponse resp = (HttpWebResponse)request.GetResponse())
{
return resp.StatusCode.ToString();
}
}
private string AuthorizationHeader1(string method, string now, HttpWebRequest request, string storageAccount, string storageKey)
{
string headerResource = $"x-ms-blob-type:BlockBlob\nx-ms-date:{now}\nx-ms-version:2015-12-11";
string urlResource = $"/{storageAccount}";
String AuthorizationHeader = String.Format("{0} {1}:{2}", "SharedKey", storageAccount, storageKey);
return AuthorizationHeader;
}
答案 0 :(得分:2)
您的AuthorizationHeader1
方法存在一些问题。有关如何构建授权标头的说明,请参阅Authentication for the Azure Storage Services
。请尝试以下代码:
private static string AuthorizationHeader1(string method, string now, HttpWebRequest request, string storageAccount, string storageKey)
{
string headerResource = $"x-ms-date:{now}\nx-ms-version:2015-12-11";
string canonicalizedResource = $"/{storageAccount}/\ncomp:list\nmaxresults:3";
var contentEncoding = "";
var contentLanguage = "";
var contentLength = "";
var contentMd5 = "";
var contentType = "";
var date = "";
var ifModifiedSince = "";
var ifMatch = "";
var ifNoneMatch = "";
var ifUnmodifiedSince = "";
var range = "";
var stringToSign = $"{method}\n{contentEncoding}\n{contentLanguage}\n{contentLength}\n{contentMd5}\n{contentType}\n{date}\n{ifModifiedSince}\n{ifMatch}\n{ifNoneMatch}\n{ifUnmodifiedSince}\n{range}\n{headerResource}\n{canonicalizedResource}";
var signature = "";
using (var hmacSha256 = new HMACSHA256(Convert.FromBase64String(storageKey)))
{
var dataToHmac = Encoding.UTF8.GetBytes(stringToSign);
signature = Convert.ToBase64String(hmacSha256.ComputeHash(dataToHmac));
}
String AuthorizationHeader = String.Format("{0} {1}:{2}", "SharedKey", storageAccount, signature);
return AuthorizationHeader;
}
