使用 OAuth1.0 调用 REST Api 到 C# 应用程序上的 netsuite SuiteTalk

Question

现在我正在尝试使用 RestSharp 连接到 C# 应用程序上的 Netsuite SuiteTalk 的其余 api。但它 returns 未经授权的错误（401）。（使用 Postman 调用 api 有效）我的代码如下。

public string generateSignature(string httpMethod, string timestamp, string nonce, 
                                        SortedDictionary<string, string> data)
{
        var parameters = new SortedDictionary<string, string>
        {
           {"oauth_consumer_key", mConfig.ConsumerKey},
           { "oauth_token", mConfig.TokenId },
           {"oauth_signature_method", "HMAC-SHA256"},
           {"oauth_timestamp", timestamp},
           {"oauth_nonce", nonce},
           {"oauth_version", "1.0"}
        };
        foreach (KeyValuePair<string, string> elt in data)
        {
             parameters.Add(elt.Key, elt.Value);
        }
        string Signature_Base_String = httpMethod;
        Signature_Base_String = Signature_Base_String.ToUpper();
        Signature_Base_String = Signature_Base_String + "&";
        string PercentEncodedURL = Uri.EscapeDataString(netsuite_base_url);
        Signature_Base_String = Signature_Base_String + PercentEncodedURL;
        Signature_Base_String = Signature_Base_String + "&";
        bool first = true;
        foreach (KeyValuePair<string, string> elt in parameters)
        {
            if (first)
            {
                Signature_Base_String = Signature_Base_String + Uri.EscapeDataString(elt.Key + "=" + elt.Value);
                first = false;
            }
            else
            {
                Signature_Base_String = Signature_Base_String + Uri.EscapeDataString("&" + elt.Key + "=" + elt.Value);
            }
        }
        string key = mConfig.ConsumerSecret + "&" + mConfig.TokenSecret;
        string signature = "";
        var encoding = new System.Text.ASCIIEncoding();
        byte[] keyByte = encoding.GetBytes(key);
        byte[] messageBytes = encoding.GetBytes(Signature_Base_String);
        using (var myhmacsha256 = new HMACSHA256(keyByte))
        {
            byte[] hashmessage = myhmacsha256.ComputeHash(messageBytes);
            signature = Uri.EscapeDataString(Convert.ToBase64String(hashmessage));
        }
        return signature;
}
public bool getData()
{
   string timestamp = computeTimestamp();// ((int)(DateTime.UtcNow - new DateTime(1970, 1, 1)).TotalSeconds).ToString();
   string nonce = Convert.ToBase64String(Encoding.UTF8.GetBytes(timestamp));// computeNonce();
   var data = new SortedDictionary<string, string>{
         { "q", query}
      };
   string signature = generateSignature("GET", timestamp, nonce, data);
   netSuiteAuthorization = "OAuth " +
        "realm=" + "\""+mConfig.AccountId + "\"" + "," +
        "oauth_consumer_key=" + "\"" + mConfig.ConsumerKey + "\"" + "," +
        "oauth_token=" + "\"" + mConfig.TokenId + "\"" + "," +
        "oauth_signature_method=" + "\"" + SIGNATURE_METHOD + "\"" + "," +
        "oauth_timestamp=" + "\"" + timestamp + "\"" + "," +
        "oauth_nonce=" + "\"" + nonce + "\"" + "," +
        "oauth_version=" + "\"" + "1.0" + "\"" + "," +
        "oauth_signature= " + "\"" + signature + "\"";
       var client = new RestClient(netsuite_base_url);
       var request = new RestRequest(Method.GET);
       request.AddHeader("Authorization", netSuiteAuthorization);
       request.AddHeader("Content-Type", "application/json");
       request.AddQueryParameter("q", query);
       IRestResponse response = client.Execute(request);
       ... do something ....
}

我认为签名功能是正确的。但是我无法弄清楚401错误的原因。我在代码中缺少什么？有经验的朋友帮帮我吧

Answer 1

我猜 realm="account number" 丢失了，尝试更新签名中的 realm

Answer 2

我终于找到问题了。我不应该添加以下行

request.AddQueryParameter("q", query);

当我使用 netsuite_base_url 字符串时，url 必须是小写。
