嗨,我有一个MVC应用程序,我已经为我的Web API定义了一些依赖项.

public class AutofacWebApiDependenceResolver : IDependencyResolver
{
    private readonly IComponentContext container;
    public AutofacWebApiDependenceResolver(IContainer container)
    {

     if (container == null)
     {
         throw new ArgumentNullException("container");
     }
     this.container = container;
    }

    public object GetService(Type serviceType)
    {
        if (serviceType == null)
        {
            throw new ArgumentNullException("serviceType");
        }
        var ret = this.container.ResolveOptional(serviceType) ;
        return ret;
    }
    public IEnumerable<object> GetServices(Type serviceType)
    {            
        if (serviceType == null)
        {
            throw new ArgumentNullException("serviceType");
        }            
        Type enumerableType = typeof(IEnumerable<>).MakeGenericType(serviceType);
        var ret = (IEnumerable<object>)this.container.ResolveOptional(enumerableType);
        return ret;
    }
}

然后在我的bootstrapper类中,我在Application_Start中调用它,如下所示:

GlobalConfiguration.Configuration.DependencyResolver = …

我在我的linux服务器上安装了一个MySQL,我忘记了它的密码所以我去了,并使用我在网上找到的方法进行了更改.我做了如下:

/etc/init.d/mysql stop
mysqld_safe --skip-grant-tables &
mysql --user root mysql
SELECT * FROM user; // I checked if I could access the user table or not
update user SET password = PASSWORD('new_pass') WHERE user = 'root';
flush privileges;
exit

更新查询确实更改了密码,因为它显示了受影响的行数和查询OK等.

然后我重新启动了mysql

/etc/init.d/mysql stop
/etc/init.d/mysql start

现在,当我使用新密码登录时

mysql -u root -p new_pass

它仍然给我错误 "ERROR 1045(28000):拒绝访问用户'root'@'localhost'(使用密码:是)"

有什么东西我错过了吗？

我是MongoDB的新手.我有一个具有以下定义的对象

[BsonDiscriminator("user")]
public Class BrdUser
{
    [BsonId(IdGenerator = typeof(StringObjectIdGenerator))]
    public string ID { get; set; }

    [BsonElement("username")]
    public string UserNm { get; set; }

    [BsonElement("email")]
    public string EmailAdrs { get; set; }
    .
    .
    .
    public IList<Question> Questions{ get; set; } //<-- Un sure as to what Bson type should this be
}

凡Questions被另一个BsonDocument定义为:

[BsonDiscriminator("userques")]
public class Question
{
    [BsonId(IdGenerator = typeof(StringObjectIdGenerator))]
    public string ID { get; set; }

    [BsonElement("title")]
    public string Title{ get; set; }

    [BsonElement("desc")]
    public …

我在Global.asax中有以下代码

protected void Application_AcquireRequestState(object sender, EventArgs e)
{           
    if (HttpContext.Current.Handler is IRequiresSessionState)
    {
        if (Request.IsAuthenticated)
        {
            if (HttpContext.Current.Session[this.MemberShipProvider.PrincipalSessionKey] != null)
            {
                CxPrincipal principal;
                try
                {
                    principal = (CxPrincipal)HttpContext.Current.Session[this.MemberShipProvider.PrincipalSessionKey];
                }
                catch
                {
                    principal = null;
                }

                HttpContext.Current.User = principal;
                Thread.CurrentPrincipal = principal;
            }
            else
            { 
                var identity = new CxIdentity("admin", 1, "", true);
                CxPrincipal principalLogin = new CxPrincipal(identity, 1);
                HttpContext.Current.Session[this.MemberShipProvider.PrincipalSessionKey] = principalLogin;
                HttpContext.Current.Session[SessionName.CurrentUser] = "Admin User";
                HttpContext.Current.User = principalLogin;
                Thread.CurrentPrincipal = principalLogin;
                this.FormServiceProvider.SignIn("admin", false); // this is equal to FormsAuthentication.SetAuthCookie

            } …

我有一个在SSL上运行的应用程序,我已经在System.Web下的web.config中添加了以下内容.

<httpCookies requireSSL="true" httpOnlyCookies="true" lockItem="true" />

但我仍然得到一个名为"cookieSesssion1"的无担保cookie.它没有被标记为安全.

你能告诉我我能把它标记为安全吗？

编辑: 除了Web.config指令,我在Global.asax文件中也有以下代码.

protected void Application_EndRequest(object sender, EventArgs e)
{
    if (Response.Cookies.Count > 0)
    {
        foreach (string s in Response.Cookies.AllKeys)
        {
            Response.Cookies[s].Secure = true;
        }
    }
}

以下是火箱调试的屏幕截图:

我错过了什么,请帮忙

我有一个 ASP.NET MVC 应用程序，其中包含通过 SignalR 调用的函数。ASP.NET 应用程序运行良好，所有客户端的数据都实时更新。

我可以创建一个 WinForms 应用程序并连接到同一个 SignalR 应用程序并通过它向我的 Web 应用程序推送数据吗？如果是这样，我如何通过 WinForms 连接到我的 SignalR Asp.NET MVC 应用程序。

我有一个元素

<a class="fa fa-user icon" href="#"></a>

我的要求是只要鼠标在它上面就有一个脉冲效果.

我的CSS是这样的.

.icon:hover{
    -webkit-animation: pulse 2s ease-in;
    -moz-animation: pulse 2s ease-in;
     animation: pulse 2s ease-in;
    -webkit-animation-iteration-count: infinite;
    -moz-animation-iteration-count: infinite;
    animation-iteration-count: infinite;
}


@keyframes pulse {
  0% {
    -webkit-transform: scale(1);
    opacity: 0.0;
 }
 25% {
    -webkit-transform: scale(1.35);
    opacity: 0.1;
 }
 50% {
    -webkit-transform: scale(1.7);
    opacity: 0.3;
 }
 75% {
    -webkit-transform: scale(2.05);
    opacity: 0.5;
 }
 100% {
    -webkit-transform: scale(2.4);
    opacity: 0.0;
 }
}

效果很好,但事情就是原始图标消失了.我希望原始图标在发生脉动效果时保持可见,以便在人将鼠标悬停在其上时使其突出.

我是否需要用新图标覆盖原始div？

我有一个select[multiple]我custom-multiselect在我的页面上给我的课程,我正在抓住这个DOMSubtreeModified事件如下:

HTML:

<select class="custom-multiselect"></select>

JQuery的:

$('.custom-multiselect').each(function (i, select) {
    var sel = this;
    adjustHeight(sel); //Custom function
    //Binding DOMSubtreeModified to catch if the select list gets modified by the user
    $(sel).on('DOMSubtreeModified', function () {            
        adjustHeight(sel);
    });
    //For Internet Explorer
    $(sel).on('propertychange', function () {
        adjustHeight(sel);
    });
});

这种方法完美无瑕.我想将转换DOMSubtreeModified成函数MutationObserver,因为DOMSubtreeModified折旧.

所以我做了这样的事情:

var observer = new MutationObserver(function (mutation) {
    mutation.forEach(function (m) {
        if (m.type == 'subtree') {
            adjustHeight(this);//Can I use m.target here?
        } …

我有一个为Android创建的自定义视图，其中绘制了一个Circle并将其划分为多个部分。

这是onDraw的代码：

int w = Width;
int h = Height;

int pl = PaddingLeft;
int pr = PaddingRight;
int pt = PaddingTop;
int pb = PaddingBottom;

int usableWidth = w - (pl + pr);
int usableHeight = h - (pt + pb);

int radius = Math.Min(usableWidth, usableHeight) / 2;
int cx = pl + (usableWidth / 2);
int cy = pt + (usableHeight / 2);

int lineLenght = radius - (pl * 2) - (pr * 2);

paint.Color = Color.Black; …

我有一个 ASP.NET MVC 5 应用程序，可以在开发计算机上正常运行。我发布它并在线传输文件，它生成以下错误：
