C# を使用して Magento REST API に接続する方法を示すサンプルはどこにありますか?

私が見つけたのは、少ししか理解できなかったphpのものでした。

ネットで見つけた Dropbox OAuth サンプルを使用して、Magento で機能するようにしました。

private void button1_Click(object sender, RoutedEventArgs e) 
{ 
    var consumerKey = “xxxxxxxxxxxxx”; 
    var consumerSecret = “xxxxxxxxxxxxxxxx”;

    var uri = new Uri("http://www.MagentoWebsite.com/oauth/token");

    // Generate a signature 
    OAuthBase oAuth = new OAuthBase(); 
    string nonce = oAuth.GenerateNonce(); 
    string timeStamp = oAuth.GenerateTimeStamp(); 
    string parameters; 
    string normalizedUrl; 
    string signature = oAuth.GenerateSignature(uri, consumerKey, consumerSecret, 
    String.Empty, String.Empty, “GET”, timeStamp, nonce, OAuthBase.SignatureTypes.HMACSHA1, 
    out normalizedUrl, out parameters);

    signature = HttpUtility.UrlEncode(signature);

    StringBuilder requestUri = new StringBuilder(uri.ToString()); 
    requestUri.AppendFormat("?oauth_consumer_key={0}&", consumerKey); 
    requestUri.AppendFormat("oauth_nonce={0}&", nonce); 
    requestUri.AppendFormat("oauth_timestamp={0}&", timeStamp); 
    requestUri.AppendFormat("oauth_signature_method={0}&", “HMAC-SHA1"); 
    requestUri.AppendFormat("oauth_version={0}&", “1.0"); 
    requestUri.AppendFormat("oauth_signature={0}", signature);

    var request = (HttpWebRequest)WebRequest.Create(new Uri(requestUri.ToString())); 
    request.Method = WebRequestMethods.Http.Get;

    var response = request.GetResponse();

    var queryString = new StreamReader(response.GetResponseStream()).ReadToEnd();

    var parts = queryString.Split(’&’); 
    var token = parts[1].Substring(parts[1].IndexOf(’=’) + 1); 
    var tokenSecret = parts[0].Substring(parts[0].IndexOf(’=’) + 1);

    queryString = String.Format("oauth_token={0}", token); 
    var authorizeUrl = “http://www.MagentoWebsite.com/admin/oauth_authorize?”+queryString; 
    Process.Start(authorizeUrl); 
}

BAD REQUEST残念ながら、これは応答を返します。

私は最近、Magento 用の C# REST API クライアントのプロジェクトを開始しました。

https://github.com/nickvane/Magento-RestApi

まだ完全な機能ではありませんが、oauth 認証が実装されています。このコードは、oauth 認証をサポートするrestsharpを使用します。

同じ質問がありましたが、答えが見つからなかったため、1日かけて作業しました。ここでコードを共有します。この機能で他の人に役立つことを願っています。

aspx ページで次のコードを使用して、oAuth アクセスを取得します。

        protected void Page_Load(object sender, EventArgs e)
    {
        string oauth_token = Request.QueryString["oauth_token"];
        string oauth_verifier = Request.QueryString["oauth_verifier"];

        if (string.IsNullOrEmpty(oauth_token) || string.IsNullOrEmpty(oauth_verifier))
        {
            BeginAuthorization();
        }
        else
        {
            Authorize(oauth_token,oauth_verifier);
        }
    }

    private void Authorize(string oauth_token, string oauth_verifier)
    {
        var uri = new Uri(MagentoServer + "/oauth/token");
        string oauth_token_secret = (string)Session["oauth_token_secret"];

        OAuthBase oAuth = new OAuthBase();
        string nonce = oAuth.GenerateNonce();
        string timeStamp = oAuth.GenerateTimeStamp();
        string parameters;
        string normalizedUrl;
        string signature = oAuth.GenerateSignature(uri, ConsumerKey, ConsumerSecret,
        oauth_token,oauth_token_secret, "GET", timeStamp, nonce, OAuthBase.SignatureTypes.PLAINTEXT,
        out normalizedUrl, out parameters);

        StringBuilder sb = new StringBuilder("OAuth ");
        sb.AppendFormat("oauth_verifier=\"{0}\",", oauth_verifier);
        sb.AppendFormat("oauth_token=\"{0}\",", oauth_token);

これが役立つかどうかはわかりませんが、Magento から oauth_token と oauth_token_secret を取得できるようになると (PHP Magento サンプルを使用して取得しました)、requestUri のすべてをヘッダー。

あなたの例は、ほとんどのコードを正しくするのに役立ち、少し変更しただけです（ここに小さなスニペットがあります）：

            StringBuilder sb = new StringBuilder("OAuth ");
            sb.AppendFormat("oauth_version={0},", "1.0");
            sb.AppendFormat("oauth_signature_method={0},", "HMAC-SHA1");
            sb.AppendFormat("oauth_nonce={0},", nonce);
            sb.AppendFormat("oauth_timestamp={0},", timeStamp);
            sb.AppendFormat("oauth_consumer_key={0},", consumerKey);
            sb.AppendFormat("oauth_token={0},", oauth_token);
            sb.AppendFormat("oauth_signature={0}", sig);

            Debug.WriteLine(sb.ToString());
            var request = (HttpWebRequest)WebRequest.Create((resourceUrl));
            request.Headers[HttpRequestHeader.Authorization] = sb.ToString();
            request.ContentType = "text/xml";
            request.Accept = "text/xml";
            request.KeepAlive = true;
            //request.Method = WebRequestMethods.Http.Get;
            request.Method = "GET";

            HttpWebResponse response = (HttpWebResponse)request.GetResponse();
            Debug.WriteLine(response.StatusCode);
            Debug.WriteLine(response.Server);
            if (response.StatusCode == HttpStatusCode.OK)
            {

                Stream responseStream = response.GetResponseStream();
                StreamReader responseReader = new StreamReader(responseStream);
                XmlDocument xmlDoc = new XmlDocument();
                xmlDoc.Load(response.GetResponseStream());
                Dts.Variables["User::XML_Response"].Value = xmlDoc.OuterXml.ToString();

            }

それは役に立ちますか？

Spring.NET Social を使用してクライアント REST API をすばやく作成できます: http://www.springframework.net/social/

Magento は Twitter と同様に OAuth 1.0a 認証を使用します。ここで Twitter の実装を確認できます: http://www.springframework.net/social-twitter/
