动态方法调用 为什么不安全 关于C#调用WebServices的方法(5)

调用方法如下

       Hashtable ht = new Hashtable();
            ht.Add("LoginName", "Admin");
            ht.Add("Password", "Password");
            ht.Add("Aey", "123");
       var data = HttpHelper.SoapV1_2WebService("http://localhost/OpenApi/MobileService.asmx", "Login", ht, "http://tempuri.org/");

以下是 HTTP GET 请求和响应示例。所显示的占位符需替换为实际值。

GET /OpenApi/MobileService.asmx/Login?LoginName=string&Password=string&Aey=string HTTP/1.1
Host: gps.szwearable.com

HTTP/1.1 200 OK
Content-Type: text/xml; charset=utf-8
Content-Length: length

<?xml version="1.0" encoding="utf-8"?>
<boolean xmlns="http://tempuri.org/">boolean</boolean>

 以上GET示例相应代码如下

 /// <summary>
        /// 需要WebService支持Get调用
        /// </summary>
        public static string WebServiceGet(String URL, String MethodName, Hashtable Pars)
        {
            HttpWebRequest request = (HttpWebRequest)HttpWebRequest.Create(URL + "/" + MethodName + "?" + HashtableToPostData(Pars));
            request.Method = "GET";
            request.ContentType = "application/x-www-form-urlencoded";
            // 凭证
            request.Credentials = CredentialCache.DefaultCredentials;
            //超时时间
            request.Timeout = 10000;
            var response = request.GetResponse();
            var stream = response.GetResponseStream();
            StreamReader sr = new StreamReader(stream, Encoding.UTF8);
            String retXml = sr.ReadToEnd();
            sr.Close();
            return retXml;
        }
        private static String HashtableToPostData(Hashtable ht)
        {
            StringBuilder sb = new StringBuilder();
            foreach (string k in ht.Keys)
            {
                if (sb.Length > 0)
                {
                    sb.Append("&");
                }
                sb.Append(HttpUtility.UrlEncode(k) + "=" + HttpUtility.UrlEncode(ht[k].ToString()));
            }
            return sb.ToString();
        }
