Athlectual的回复似乎并不适用于当前的openstack.net NuGet包,但我试图通过反复试验来使其与最新版本(1.1.2.1)一起工作。希望这会帮助其他人
就我而言,似乎我没有设置临时URL元数据密钥,因为已经设置了Temp URL元数据密钥,必须在创建帐户时随机生成。因此,获取工作的临时URL的代码如下所示。
N.b.我已经使用用户名和APIKey进行身份验证。我想你可以使用密码来代替。您可以在Rackspace云控制面板网站中的帐户详细信息中找到APIKey。
private static string GetCloudFilesTempUrl(Uri storageUrl, string username, string apiKey, string containerName, string filename)
{
var cloudIdentity = new CloudIdentity()
{
Username = username,
APIKey = apiKey
};
var provider = new CloudFilesProvider(cloudIdentity);
var accountMetaData = provider.GetAccountMetaData();
var tempUrlKey = accountMetaData["Temp-Url-Key"];
//Set the link to expire after 60 seconds (in epoch time)
var epochExpire = ((int) (DateTime.UtcNow - new DateTime(1970, 1, 1)).TotalSeconds) + 60;
//The path to the cloud file
var path = string.Format("{0}/{1}/{2}", storageUrl.AbsolutePath, containerName, filename);
var hmacBody = string.Format("GET\n{0}\n{1}", epochExpire, path);
var hashSaltBytes = Encoding.ASCII.GetBytes(tempUrlKey);
string sig;
using (var myhmacMd5 = new HMACSHA1(hashSaltBytes))
{
var ticketBytes = Encoding.ASCII.GetBytes(hmacBody);
var checksum = myhmacMd5.ComputeHash(ticketBytes);
var hexaHash = new StringBuilder();
foreach (var b in checksum)
{
hexaHash.Append(String.Format("{0:x2}", b));
}
sig = hexaHash.ToString();
}
var cloudFileUrl = string.Format("https://{0}{1}", storageUrl.Host, path);
//Compile the temporary URL
return string.Format("{0}?temp_url_sig={1}&temp_url_expires={2}", cloudFileUrl, sig, epochExpire);
}
我不知道你是如何打算让存储URL,而是通过更多的试验和错误我管理这个:
private static string GetCloudFilesStorageUrl(string username, string apiKey)
{
var cloudIdentity = new CloudIdentity()
{
Username = username,
APIKey = apiKey
};
var identityProvider = new CloudIdentityProvider(cloudIdentity);
return identityProvider.GetUserAccess(cloudIdentity)
.ServiceCatalog
.Single(x => x.Name == "cloudFiles")
.Endpoints[0].PublicURL;
}
如前所述,我没有设置临时URL密钥,我可能不会去尝试,以防我破坏某些工作!如果你需要,但我猜猜以下应该做的伎俩:
private static void SetCloudFilesTempUrlKey(string username, string apiKey, string tempUrlKey)
{
var cloudIdentity = new CloudIdentity()
{
Username = username,
APIKey = apiKey
};
var provider = new CloudFilesProvider(cloudIdentity);
provider.UpdateAccountMetadata(new Metadata
{
{ "Temp-Url-Key", tempUrlKey }
});
}
