これは私が使用しているコードです

Http クライアント:

}

crfs-token の取得:

private string GetToken()
    {
        string token = "";
        String sourcestring = hc.GetData(loginURL);
        Regex metaTag = new Regex(@"<meta[\s]+[^>]*?name[\s]?=[\s""']+(.*?)[\s""']+content[\s]?=[\s""']+(.*?)[""']+.*?>");
        foreach (Match m in metaTag.Matches(sourcestring))
        {
            if (m.Groups[2].Value.Contains("token"))
            {
                continue;
            }

            token = m.Groups[2].Value;
        }

            return token;
    }

カスタム キーと値のペア

private string PostParam(Dictionary<string, string> data)
    {
        var sb = new StringBuilder();
        var p = new List<string>();
        foreach (KeyValuePair<string, string> pair in data)
        {
            sb.Clear();
            sb.Append(pair.Key).Append("=").Append(pair.Value);
            p.Add(sb.ToString());
        }
        var pp = string.Join("&", p);
        return pp;
    }

ログイン：

 private HttpClient hc = new HttpClient();

辞書データ = 新しい Dictionary();

        data.Add("utf8", "✓");
        data.Add("authenticity_token", GetToken());
        data.Add("plan", "");
        data.Add("email", "email");
        data.Add("password", "password");
        hc.PostData(sessionURL,WebUtility.UrlEncode(PostParam(data)), loginURL);

誰かが私が間違っていることを教えてもらえますか? ブラウザで Strava にログインしようとしたときにリクエスト ヘッダーを見ても同じですが、それでもログに記録されません。
