Html：
<div class="field">
<input type="text" class="input input-big" name="code" placeholder="填写右侧的验证码" data-validate="required:请填写右侧的验证码" />
<img src="/Login/ShowVCode" id="LoginCode" alt="" width="100" height="32" class="passcode" style="height:43px;cursor:pointer;" onclick="this.src=this.src+'?'">
</div>
</div>
控制器：
#region 验证码生成
public ActionResult ShowVCode()
{
ValidateCode validateCode = new ValidateCode();
string strCode = validateCode.CreateValidateCode(4);
Session["VCode"] = strCode;
byte[] imgBytes = validateCode.CreateValidateGraphic(strCode);
return File(imgBytes, @"image/jpeg");
}
#endregion
在控制器上怎么接受到验证码：
#region 验证
public ActionResult Logincode()
{
string strCode = Request["code"];//接收到的Code
string sessionCode = Session["VCode"] as string;//生成的Code
Session["VCode"] = null;
if (string.IsNullOrEmpty(sessionCode))
{
//return Content("验证码失败");
return Redirect("Index");
}
if (strCode == sessionCode)
{
// return Content("验证码正确");
// return Redirect("/Shopper/Index");
return RedirectToAction("Index", "Shopper", new { name = UserName });
}
else
{
//return Content("验证码失败");
return Redirect("Index");
}
}
#endregion
