[英]Call REST Api using OAuth1.0 to netsuite SuiteTalk on C# application
現在我正在嘗試使用 RestSharp 在 C# 應用程序上連接到 Netsuite SuiteTalk 的 rest api。 但它返回未經授權的錯誤(401)。 (使用 Postman 調用 api 有效)我的代碼如下。
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 ....
}
我認為簽名 function 是正確的。 但是我無法弄清楚401錯誤的原因。 我在代碼中缺少什么? 如果有人有經驗,請幫助我。
我猜 realm="account number" 丟失,嘗試更新簽名中的 realm
我終於找到了問題。 我不應該添加以下行
request.AddQueryParameter("q", query);
而當我使用 netsuite_base_url 字符串時,url 必須是小寫的。
示例: RestSharp版本:108.0.3
不需要編寫簽名創建代碼。 RestSharp 為您做這一切。
using System;
using RestSharp;
using RestSharp.Authenticators;
using RestSharp.Authenticators.OAuth;
using Newtonsoft.Json;
var client = new RestClient(URL);
var oAuth1 = OAuth1Authenticator.ForAccessToken(
consumerKey: ConsumerKey,
consumerSecret: ConsumerSecret,
token: Token,
tokenSecret: TokenSecret,
OAuthSignatureMethod.HmacSha256);
oAuth1.Realm = Realm; // if Realm has otherwise ignore
client.Authenticator = oAuth1;
var request = new RestRequest(URL, Method.Post);
request.AddHeader("Content-Type", "application/json");
string body = JsonConvert.SerializeObject(bodyObject);
request.AddParameter("application/json", body, ParameterType.RequestBody);
var response = client.Execute(request);
