Question

编辑：问题是参数.ToString（）。也像冷宁刘指出你需要添加＆＃39; / sprocs / sprocname＆＃39;

我尝试在ASP.NET Core 1.0 / C＃中使用REST调用在Azure DocumentDB中执行存储过程。

我使用此MSDN页面上的方法生成哈希： https://msdn.microsoft.com/library/azure/dn783368.aspx

我获得了401 Unauthorized repsonse。是＆＃34; sprocs＆＃34;正确的文件类型，还是我必须输入其他类型？

public class Database
{

    public async Task<HttpResponseMessage> StoredProcedure(string database, string collection, string storedProcedure, string[] parameters)
    {
        //https://{databaseaccount}.documents.azure.com/dbs/{db-id}/colls/{coll-id}/sprocs/{sproc-name}

        string resourceLink = $"dbs/{database}/colls/{collection}";
        var client = Client("POST", resourceLink, "sprocs");

        StringContent content = new StringContent(parameters.ToString(), null, "application/query+json");
        var uri = new Uri(_endpointUri, $"dbs/{database}/colls/{collection}/sprocs/{storedProcedure}");
        HttpResponseMessage response = await client.PostAsync(uri, content);

        return response;
    }

    private HttpClient Client(string verb, string resourceLink, string resourceType)
    {
        var client = new HttpClient();
        var utc_date = DateTime.UtcNow.ToString("r");
        client.DefaultRequestHeaders.Add("x-ms-date", utc_date);
        client.DefaultRequestHeaders.Add("x-ms-version", "2015-12-16");
        client.DefaultRequestHeaders.Add("x-ms-max-item-count", "10000");

        var authHeader = GenerateMasterKeyAuthorizationSignature(utc_date, verb, resourceLink, resourceType, _authorizationKey, "master", "1.0");

        client.DefaultRequestHeaders.Add("authorization", authHeader);

        return client;
    }

    private static string GenerateMasterKeyAuthorizationSignature(string utc_date, string verb, string resourceId, string resourceType, string key, string keyType, string tokenVersion)
    {

        var hmacSha256 = new System.Security.Cryptography.HMACSHA256 { Key = Convert.FromBase64String(key) };

        string payLoad = string.Format(System.Globalization.CultureInfo.InvariantCulture, "{0}\n{1}\n{2}\n{3}\n{4}\n",
                verb.ToLowerInvariant(),
                resourceType.ToLowerInvariant(),
                resourceId,
                utc_date.ToLowerInvariant(),
                ""
        );

        byte[] hashPayLoad = hmacSha256.ComputeHash(System.Text.Encoding.UTF8.GetBytes(payLoad));
        string signature = Convert.ToBase64String(hashPayLoad);

        return System.Net.WebUtility.UrlEncode(String.Format(System.Globalization.CultureInfo.InvariantCulture, "type={0}&ver={1}&sig={2}",
            keyType,
            tokenVersion,
            signature));
    }
}

似乎在生成身份验证令牌时，在resourceId部分中，您省略了“/ sprocs / {storedProcedure}”。你把它包含在uri中，这是正确的。

我附加了一个示例powershell脚本，希望它还可以帮助您查看如何生成身份验证令牌。
