現在我正在嘗試使用 RestSharp 在 C# 應用程式上連接到 Netsuite SuiteTalk 的 rest api。但它回傳未經授權的錯誤（401）。（使用 Postman 呼叫 api 正在作業）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 ....
}
我認為簽名功能是正確的。但我無法弄清楚 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。
uj5u.com熱心網友回復：
我猜 realm="account number" 丟失，嘗試在簽名中更新領域
uj5u.com熱心網友回復：
我終于找到了問題所在。我不應該添加以下行
request.AddQueryParameter("q", query);
當我使用 netsuite_base_url 字串時，url 必須是小寫的。
