public void ProcessRequest(HttpContext context) { context.Response.ContentType = "text/plain"; #region 判断用户是否被注册过 string returnStr = ""; //这里其实是context.Request.QueryString根据name获取的值 一定要设置空间的name值 if (context.Request["userName"] != null && context.Request["userName"].ToString().Length > 0) { if (isExist(context.Request["userName"].ToString())) { returnStr = "false"; } else { returnStr = "0"; } } else { returnStr = "null"; } context.Response.Write(returnStr); context.Response.End(); #endregion } #region 判断用户是否被注册过 public bool isExist(string userName) { Snet.BLL.UserAccount bll = new BLL.UserAccount(); return bll.Exists(userName); } #endregion
