问题描述
我有一个大问题.我在 C# 中处理 UWP Windows 10 应用程序,我想使用 OAuth 1.
I've a big problem. I work on a UWP Windows 10 application in C# and i would like to use OAuth 1.
一切都差不多,但签名是错误的.但是,我在 Microsoft GitHub 上找到了示例代码.显然,我做了一些修改...
All is almost okay BUT the signature is wrong. However, I found the sample code on the Microsoft GitHub. Obviously, I have done some modifications...
我的代码:
private async Task GoCo()
{
String LifeInvaderUrl = "http://stage.api.lolilolz.be/v8/login";
string timeStamp = GetTimeStamp();
string nonce = GetNonce();
string consumerKey = "noob-stage";
string consumerSecret = "TOPSECRETxxXXxx";
string SigBaseStringParams = "oauth_consumer_key=" + consumerKey;
SigBaseStringParams += "&" + "oauth_signature_method=HMAC-SHA1";
SigBaseStringParams += "&" + "oauth_timestamp=" + timeStamp;
SigBaseStringParams += "&" + "oauth_nonce=" + nonce;
SigBaseStringParams += "&" + "oauth_version=1.0";
string SigBaseString = "POST&";
SigBaseString += Uri.EscapeDataString(LifeInvaderUrl) + "&" + Uri.EscapeDataString(SigBaseStringParams);
String Signature = GetSignature(SigBaseString, consumerSecret);
string authorizationHeaderParams = "oauth_consumer_key="" + consumerKey + "", oauth_signature_method="HMAC-SHA1", oauth_timestamp="" + timeStamp + "", oauth_nonce="" + nonce + "", oauth_vesrion="1.0", oauth_signature="" + Uri.EscapeDataString(Signature)+ """;
HttpClient httpClient = new HttpClient();
//...
}
和签名生成器方法:
string GetSignature(string sigBaseString, string consumerSecretKey)
{
IBuffer KeyMaterial = CryptographicBuffer.ConvertStringToBinary(consumerSecretKey + "&", BinaryStringEncoding.Utf8);
MacAlgorithmProvider HmacSha1Provider = MacAlgorithmProvider.OpenAlgorithm("HMAC_SHA1");
CryptographicKey MacKey = HmacSha1Provider.CreateKey(KeyMaterial);
IBuffer DataToBeSigned = CryptographicBuffer.ConvertStringToBinary(sigBaseString, BinaryStringEncoding.Utf8);
IBuffer SignatureBuffer = CryptographicEngine.Sign(MacKey, DataToBeSigned);
string Signature = CryptographicBuffer.EncodeToBase64String(SignatureBuffer);
return Signature;
}
先谢谢你:)
推荐答案
您的基本字符串参数有问题.对于 OAuth 1.0,需要对其进行排序.我已经创建了用于创建基本字符串的通用函数.你可以使用它.
Your base string parameters are out of order. For OAuth 1.0 it needs to be sorted. I have created generic function for creating base string. you can use that.
` private static string GetSignatureBaseString(string strUrl, string TimeStamp,
string Nonce, string strConsumer, string strOauthToken, SortedDictionary<string, string> data)
{
//1.Convert the HTTP Method to uppercase and set the output string equal to this value.
string Signature_Base_String = "POST";
Signature_Base_String = Signature_Base_String.ToUpper();
//2.Append the ‘&’ character to the output string.
Signature_Base_String = Signature_Base_String + "&";
//3.Percent encode the URL and append it to the output string.
string PercentEncodedURL = Uri.EscapeDataString(strUrl);
Signature_Base_String = Signature_Base_String + PercentEncodedURL;
//4.Append the ‘&’ character to the output string.
Signature_Base_String = Signature_Base_String + "&";
//5.append OAuth parameter string to the output string.
var parameters = new SortedDictionary<string, string>
{
{"oauth_consumer_key", strConsumer},
{ "oauth_token", strOauthToken },
{"oauth_signature_method", "HMAC-SHA1"},
{"oauth_timestamp", TimeStamp},
{"oauth_nonce", Nonce},
{"oauth_version", "1.0"}
};
//6.append parameter string to the output string.
foreach (KeyValuePair<string, string> elt in data)
{
parameters.Add(elt.Key, elt.Value);
}
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);
}
}
return Signature_Base_String;
}
`使用上面的函数,您将获得可以使用您的密钥传递给下面的函数并获得签名的基础
` Using above function you will get base which you can pass to below function with your secret key and get signature
private static string GetSha1Hash(string key, string base)
{
var encoding = new System.Text.ASCIIEncoding();
byte[] keyBytes = encoding.GetBytes(key);
byte[] messageBytes = encoding.GetBytes(base);
string strSignature = string.Empty;
using (HMACSHA1 SHA1 = new HMACSHA1(keyBytes))
{
var Hashed = SHA1.ComputeHash(messageBytes);
strSignature = Convert.ToBase64String(Hashed);
}
return strSignature;
}
