关于.NET对接淘宝API的问题
本帖最后由 xuzhenshun 于 2013-07-02 09:48:19 编辑 最近在学着对接淘宝的API

在登录那里被被搞晕了，下面是淘宝的说明
http://open.taobao.com/doc/detail.htm?spm=0.0.0.0.sIg3jQ&id=118

我是使用Server-side flow方法来获取

(1) 通过用户授权获取授权码Code； （获取授权码 :https://oauth.taobao.com/authorize ；沙箱访问 https://oauth.tbsandbox.com/authorize ）

//沙箱环境
        protected string AppKey = "102223556992";
        protected string AppSecret = "sand3xc00f28d1f022ae6343ed69f5d";


        protected void Page_Load(object sender, EventArgs e)
        {
            string url = "https://oauth.tbsandbox.com/authorize"; //沙箱环境
            //参数
            taobao.Model.parameterCode model = new Model.parameterCode()
            {
                client_id = AppKey,
                redirect_uri = "localhost:50138/OAuth.aspx",
                response_type = "code",
                state = "13",
                view = "web"
            };

            url += ("?client_id=" + model.client_id + "&redirect_uri=" + model.redirect_uri + "&response_type=" + model.response_type + "&state=" + model.state + "&view=" + model.view);

            Response.Redirect(url);
        }

这个第一步我已经完成了，然后完成后淘宝自动呆着code回转到localhost:50138/OAuth.aspx这个页面，这个页面的CS代码如下第二步所释。

(2) 用上一步获取的Code和应用密钥（AppSecret）通过Https Post方式换取Token。 （获取访问令牌： https://oauth.taobao.com/token ； 沙箱访问 https://oauth.tbsandbox.com/token ）

//沙箱环境
        protected string AppKey = "102223556992"; 
 
        protected string AppSecret = "sand3xc00f28d1f022ae6343ed69f5d";

        protected void Page_Load(object sender, EventArgs e)
        {
            if (Request.QueryString["code"] != null)
            {
                //获取到授权码Code，执行获取Access ToKen方法
                GetAccessToKen(Request.QueryString["code"].ToString());
            }
        }

        //获取Access ToKen令牌方法
        protected void GetAccessToKen(string code)
        {
            string url = "https://oauth.tbsandbox.com/token";  //沙箱环境

            #region 参数整合
            taobao.Model.parameterAccessToKen model = new Model.parameterAccessToKen()
            {
                client_id = AppKey,
                client_secret = AppSecret,
                code = code,
                grant_type = "authorization_code",
                redirect_uri = "localhost:50138/OAuth.aspx",
                state = "13",
                view = "web"
            };

            string strCan = "";
            strCan += ("client_id=" + model.client_id);
            strCan += ("&client_secret=" + model.client_secret); 
 
            strCan += ("&code=" + model.code);
            strCan += ("&grant_type=" + model.grant_type);
            strCan += ("&redirect_uri=" + model.redirect_uri);
            strCan += ("&state=" + model.state);
            strCan += ("&view=" + model.view);
            #endregion

            Response.Write(GetPage(url, strCan));

        }


        /// <summary>  
        /// Post数据到网站  
        /// </summary>  
        /// <param name="posturl">网址</param>  
        /// <param name="postData">参数</param>  
        /// <returns></returns>  
        public string GetPage(string posturl, string postData)
        {
            Stream outstream = null;
            Stream instream = null;
            StreamReader sr = null;
            HttpWebResponse response = null;
            HttpWebRequest request = null;
            Encoding encoding = System.Text.Encoding.GetEncoding("UTF-8");
            byte[] data = encoding.GetBytes(postData);
            // 准备请求...  
            try
            {
                // 设置参数   
 
                request = WebRequest.Create(posturl) as HttpWebRequest;
                CookieContainer cookieContainer = new CookieContainer();
                request.CookieContainer = cookieContainer;
                request.AllowAutoRedirect = true;
                request.Method = "POST";
                request.ContentType = "application/x-www-form-urlencoded";
                request.ContentLength = data.Length;
                outstream = request.GetRequestStream();
                outstream.Write(data, 0, data.Length);
                outstream.Close();
                //发送请求并获取相应回应数据  
                response = request.GetResponse() as HttpWebResponse;
                //直到request.GetResponse()程序才开始向目标网页发送Post请求  
                instream = response.GetResponseStream();
                sr = new StreamReader(instream, encoding);
                //返回结果网页（html）代码  
                string content = sr.ReadToEnd();
                string err = string.Empty;
                return content;
            }
            catch (Exception ex)
            { 
 
                string err = ex.Message;
                return err;
            }
        }

但是，这个第二部怎么都弄好不！尤其是“通过Https Post方式换取Token”我都改了好多种POST的方法了，还是不行，每次都会报错“基础连接已经关闭: 未能为 SSL/TLS 安全通道建立信任关系。”
淘宝API .NET对接淘宝API Access?Token session?key 沙箱环境
[解决办法]
人家用的ssl/tls

//如果是发送HTTPS请求
if(url.StartsWith("https",StringComparison.OrdinalIgnoreCase))
{
ServicePointManager.ServerCertificateValidationCallback = new RemoteCertificateValidationCallback(CheckValidationResult);
request = WebRequest.Create(url) as HttpWebRequest;
request.ProtocolVersion=HttpVersion.Version10;
}

你post加上这个
