关于Ajax请求WebService

1、前台脚本

 1 <script type="text/javascript" language="javascript">
 2     var url = window.location.protocol + "//" + window.location.host;
 3     if (window.location.port != "") {
 4         url += ":" + window.location.port
 5     }
 6 
 7     var strUrl = url + "/WebService/OAService.asmx/EncryptDES";
 8     $.ajax({
 9         async: false,
10         type: "POST",
11         url: strUrl,
12         data: "{encryptString:'powerpip'}",
13         dataType: "json",
14         contentType: "application/json; charset=utf-8",
15         success: function (result) {
16             
17             dataResult = result.d; alert(dataResult);
18         },
19         error: function (XMLHttpRequest) {
20             alert("error");
21         }
22     });
23 
24 
25 </script>

 

2、WebService

 1 // 若要允许使用 ASP.NET AJAX 从脚本中调用此 Web 服务，请取消注释以下行。 
 2     [System.Web.Script.Services.ScriptService]
 3 
 4  /// <summary>
 5         /// DES加密字符串
 6         /// </summary>
 7         /// <param name="loginname"></param>
 8         /// <returns></returns>
 9         [WebMethod(Description = "DES加密字符串")]
10         public string EncryptDES(string encryptString)
11         {
12             ComOp com = new ComOp();
13 
14             return com.EncryptDES(encryptString, com.EncryptKey);
15         }

 

3、Web.Config

<system.web>

<webServices>
      <protocols>
        <add name="HttpPost"/>
        <add name="HttpGet"/>
      </protocols>
    </webServices>

</system.web>
