小编Mic*_*elS的帖子

我有以下CSS

h1:before {
    content: "Chapter " counter(lvl1) "\000d\000a";
    counter-increment: lvl1;
    white-space: pre-wrap;
}
h1 {
    page-break-before: right;
}

和这个HTML

<p>...</p>
<h1>A Title</h1>
<p>...</p>

使用给定的CSS,我得到类似的东西

Chapter 1
A Title

当我尝试使用jQuery获取文本时,我得到"A Title".是否有可能获得"第1章\n标题"？

谢谢

我使用 IdentityServerAccessTokenType.Reference和一个 API。API 无法通过以下错误日志对请求的用户进行身份验证：

我正在为一个新项目尝试使用caliburn.micro框架,但我坚持使用绑定ListPicker(工具包中的那个).当我将控件更改为简单的DropDown时,一切都按预期工作.我假设DropDown工作正常,因为这里实现了默认约定:

AddElementConvention<Selector>(Selector.ItemsSourceProperty, "SelectedItem", "SelectionChanged")
    .ApplyBinding = (viewModelType, path, property, element, convention) => {
        if (!SetBinding(viewModelType, path, property, element, convention))
            return false;

        ConfigureSelectedItem(element, Selector.SelectedItemProperty,viewModelType, path);
        ApplyItemTemplate((ItemsControl)element, property);

        return true;
    };

ListPicker没有实现Selector,所以我试图在我的引导程序中添加一个自定义约定:

static void AddCustomConventions() {
    AddElementConvention<ListPicker>(ListPicker.ItemsSourceProperty, "SelectedItem", "SelectionChanged")
        .ApplyBinding = (viewModelType, path, property, element, convention) => {
            ConventionManager.ConfigureSelectedItem(element, ListPicker.SelectedItemProperty,viewModelType, path);
            return true;
        };
}

不幸的是,这不起作用.你能帮我吗？

我想从控制台应用程序发布WCF服务。为了安全起见，我想通过SSL进行通信，因此我创建了一个自签名证书。为了进行身份验证，我编写了自己的UserNamePasswordValidator。不幸的是，这不起作用

到目前为止，这是我的代码：

服务器

public class Program
{
    public static void Main()
    {
        var baseAddress = new Uri("https://localhost:8080/SelfHostedUsernamePasswordService");

        using (var host = new ServiceHost(typeof(SelfHostedUsernamePasswordService), baseAddress))
        {
            var binding = new BasicHttpBinding(BasicHttpSecurityMode.TransportWithMessageCredential);
            binding.Security.Transport.ClientCredentialType = HttpClientCredentialType.Basic;
            binding.Security.Message.ClientCredentialType = BasicHttpMessageCredentialType.Certificate;

            var endpoint = host.AddServiceEndpoint(typeof(ISelfHostedUsernamePasswordService), binding, baseAddress);

            var cf = new ChannelFactory<ISelfHostedUsernamePasswordService>(binding, endpoint.Address);
            cf.Credentials.ClientCertificate.SetCertificate(
                StoreLocation.LocalMachine,
                StoreName.My,
                X509FindType.FindByThumbprint,
                "0000000000000000000000000000000000000000");

            var metadataBehavior = new ServiceMetadataBehavior();
            metadataBehavior.HttpsGetEnabled = true;
            metadataBehavior.MetadataExporter.PolicyVersion = PolicyVersion.Policy15;
            host.Description.Behaviors.Add(metadataBehavior);

            var credentialBehavior = new ServiceCredentials();
            credentialBehavior.UserNameAuthentication.CustomUserNamePasswordValidator = new UsernamePasswordValidator();
            credentialBehavior.UserNameAuthentication.UserNamePasswordValidationMode = UserNamePasswordValidationMode.Custom;

我正在使用Visual Studio 2015 Community Edition并将我现有的ASP.NET MVC6应用程序更新为beta7.现在我不能再打开项目了.Visual Studio崩溃时出现以下异常:
