Hashtable ht = new Hashtable();
string uname = Request.Params["user_name"];
string pwd = Request.Params["user_pwd"];
int wrongTypeName = 0;
int wrongTypePwd = 0;
uname = PageValidate.InputText(uname, 30);
if (Validator.StrIsNullOrEmpty(uname))
{
wrongTypeName = 1;
}
if (Validator.StrIsNullOrEmpty(pwd))
{
wrongTypePwd = 1;
}
if (!string.IsNullOrEmpty(uname) && !string.IsNullOrEmpty(pwd))
{
//以下使用常量来做演示：
string userName="ethan.zhu";
string password ="";//需要MD5加密之后的字符串
if (uname==userName&&password==pwd )
ht.Add("loginSuccess", 0);
else
wrongTypeName = 4;//返回用户名或密码错误
if (wrongTypeName > 0 || wrongTypePwd > 0)
{
ht.Add("wrongTypeName", wrongTypeName);
ht.Add("wrongTypePwd", wrongTypePwd);
}
Response.Write(CreateJsonParams(ht));
}
Response.End();
}
将Hashtable转换成json：
复制代码 代码如下:
public static string CreateJsonParams(Hashtable items)
{
string returnStr = "";
foreach (DictionaryEntry item in items)
{
returnStr += "\"" + item.Key.ToString() + "\":\"" + item.Value.ToString() + "\",";
}
return "{" + returnStr.Substring(0, returnStr.Length - 1) + "}";
}
