Jquery ajax调用webservice总结

jquery ajax调用webservice(C#)要注意的几个事项：

1、web.config里需要配置2个地方

2.正确地编写webserivce的代码

/// <summary>
/// UserValidate 的摘要说明
/// </summary>
[WebService(Namespace = "http://tempuri.org/")]
[WebServiceBinding(ConformsTo = WsiProfiles.BasicProfile1_1)]
[System.ComponentModel.ToolboxItem(false)]
// 若要允许使用 ASP.NET AJAX 从脚本中调用此 Web 服务，请取消对下行的注释。
[System.Web.Script.Services.ScriptService]
public class UserValidate : System.Web.Services.WebService
{
DFHon.Content.Common.rootPublic rp = new DFHon.Content.Common.rootPublic();
[WebMethod]
[ScriptMethod(ResponseFormat = ResponseFormat.Json)]
public string ValidateUserLogState()
{
string result = "";
HttpCookie cookie = HttpContext.Current.Request.Cookies["DHFonMenberInfo"];
if (cookie != null)
{
string username = System.Web.HttpUtility.UrlDecode(cookie["MenberName"]);
int ipoint = 0;
int gpoint = 0;
try
{
DataTable dt = UserBll.ExecuteUserAllInfo(username);

if (dt.Rows.Count > 0)
{
ipoint = int.Parse(dt.Rows[0]["iPoint"].ToString());
gpoint = int.Parse(dt.Rows[0]["gPoint"].ToString());
}
}
catch
{ }
result = "{'user':{'id':'" + cookie["UserId"] + "','name':'" + username + "','message':'" + rp.getUserMsg(DFHon.Global.CurrentCookie.UserName) + "','ipoint':'" + ipoint.ToString() + "','gpoint':'" + gpoint.ToString() + "'}}";
