我已经搜索了很多这个问题并且它们似乎都有相同的答案,似乎属于由视图而不是控制器调用。
我已尝试实施答案,但我在这部分NullReferenceException
上获得了url.RequestContext.HttpContext.Request.Url.Scheme;
我引用了System.Web.Mvc;
,但我仍无法拨打Url.Action
。相反,我必须创建UrlHelper
的新对象,然后调用Action
方法。我不确定这是否是我的问题的原因。
我的代码如下:
public static class EmailHelper
{
public static string AbsoluteAction(this UrlHelper url, string actionName, string controllerName, object routeValues = null)
{
// Throws NullReferenceException
string scheme = url.RequestContext.HttpContext.Request.Url.Scheme;
return url.Action(actionName, controllerName, routeValues, scheme);
}
public static async Task SendReset(string emailAddress)
{
MailDefinition md = new MailDefinition()
{
IsBodyHtml = true,
Subject = "Password Reset",
BodyFileName = "~/Templates/ResetConfirm.html",
};
UrlHelper helper = new UrlHelper();
string url = helper.AbsoluteAction("Login", "Account");
ListDictionary replacements = new ListDictionary();
replacements.Add("{{LoginUrl}}", url);
MailMessage msg = md.CreateMailMessage(emailAddress, replacements, new System.Web.UI.Control());
SmtpClient client = new SmtpClient();
await client.SendMailAsync(msg);
}
}
修改
我从SendReset
的{{1}}帖子操作中致电AccountController
ResetPassword

UrlHelper
属性Url
也可以在控制器中访问,因此请将该实例提供给您的方法以访问UrlHelper
:
public async Task<ActionResult> ResetPassword(ResetPasswordViewModel model)
{
// some code here...
await EmailHelper.SendReset(Url, model.Email);
//...
}
public static class EmailHelper
{
public static async Task SendReset(UrlHelper urlHelper, string emailAddress)
{
//...
string url = urlHelper.AbsoluteAction("Login", "Account");
}
}
