我正在尝试使用 Table API 访问 Azure Cosmos DB。
挑战是,尽管创建了 SharedKeyLite,服务器仍然返回 Unauthorized - 似乎 SharedKeyLite 不受支持,或者我生成的签名或标头错误。
这是代码
static readonly string storageAccountName = "accountName";
static readonly string storageAccountKey = "xxxx";
static readonly string uri = "https://accountName.table.cosmosdb.azure.com/Contacts()";
static readonly string utc_date = DateTime.UtcNow.ToString("r");
static void Main(string[] args)
{
Console.WriteLine(GetResult().Result);
}
static async Task<string> GetResult()
{
// Set this to whatever payload you desire. Ours is null because
// we're not passing anything in.
Byte[] requestPayload = null;
var requestDateString = DateTime.UtcNow.ToString("R", CultureInfo.InvariantCulture);
var requestUri = new Uri(uri);
DateTime now = DateTime.UtcNow;
//Instantiate the request message with a null payload.
using (var httpRequestMessage = new HttpRequestMessage(HttpMethod.Get, uri)
{ Content = (requestPayload == null) ? null : new ByteArrayContent(requestPayload) })
{
ConstructHeaders(httpRequestMessage.Headers, requestDateString);
string authorizationHeader = GenerateSharedKeyLite(storageAccountKey, storageAccountName, uri,requestDateString);
httpRequestMessage.Headers.Authorization = new AuthenticationHeaderValue("SharedKeyLite", authorizationHeader);
// Send the request.
using (HttpResponseMessage httpResponseMessage = await new HttpClient().SendAsync(httpRequestMessage))
{
string json = await httpResponseMessage.Content.ReadAsStringAsync();
return json;
}
}
}
这些是我添加的标题,ConstructHeaders 方法的扩展。请参阅此链接以获取请求参数
