C#蒸汽网络请求
我是初学者，在尝试登录Steam时遇到了一个问题：C#蒸汽网络请求,c#,web,rsa,steam,C#,Web,Rsa,Steam,我是初学者，在尝试登录Steam时遇到了一个问题： public Steam(string password, string login) { Password = password; Login = login; _client.DefaultRequestHeaders.Add("User-Agent", "Mozilla/5.0 (Windows NT 6.1; Win64; x64) AppleWebKit/537.36 (KHTML, like
public Steam(string password, string login)
{
Password = password;
Login = login;
_client.DefaultRequestHeaders.Add("User-Agent",

_rsa = new RSACryptoServiceProvider();
_rsaParameters = new RSAParameters();
_params = new Dictionary<string, string>();
}
public async Task GetRsa()
{
var request = await _client.GetAsync($"https://steamcommunity.com/login/getrsakey?username=" + Login);
var content = await request.Content.ReadAsStringAsync();
Timestamp = content.Between("timestamp\":\"", "\"", StringComparison.InvariantCulture);

Mod = content.Between("publickey_mod\":\"", "\"", StringComparison.InvariantCulture);

_rsaParameters.Modulus = HexToByte(Mod);
_rsaParameters.Exponent = HexToByte(Exp);
_rsa.ImportParameters(_rsaParameters);
var bytePassword = Encoding.ASCII.GetBytes(Password);
var encodedPassword = _rsa.Encrypt(bytePassword, false);
EncryptedBase64Password = Convert.ToBase64String(encodedPassword);
}
public async Task TryLogin()
{
var unixTimestamp = (int)(DateTime.UtcNow.Subtract(new DateTime(1970, 1, 1))).TotalSeconds;
//_params["donotcache"] = unixTimestamp + "000";

var responce2 = await _client.PostAsync($"https://steamcommunity.com/login/dologin/", new FormUrlEncodedContent(_params));

}
我不明白我的错误在哪里。可能是我的RSA密码错误，或者cookies有问题。您的代码看起来不错。一些需要检查的内容： 1.确保您的用户名和密码正确； 2.调用getRsaKey时，检查是否正确解析publickey\u mod&publickey\u exp 看看我的课
