找不到参考项目中的视图

问题描述

我的解决方案包含2个项目:

My solution consist of 2 projects:

• MyApp.Rest
• MyApp.Core

Core使用Razor模板生成电子邮件和报告.Rest仅是WebAPI，并引用Core.其余的具有启动文件，在该文件中进行Razor配置.将来，Core也将被其他项目使用.

Core uses Razor templating to generate emails and reports. Rest is a WebAPI only and references Core. Rest has the startup file, where Razor configuration takes place. Core will also be used by other projects in the future.

问题是，即使我已将输出目录添加为剃须刀的FileProvider，并且模板已复制到输出目录，我仍无法使视图引擎定位视图文件.

The problem is I am not able to make the view engine to locate view files even though I have added the output directory as a FileProvider for razor and the template has been copied to the output directory.

输出目录:

MyApp.Code.dll
MyApp.Rest.dll
RazorTemplates
 -> Template1.cshtml

Startup.cs

Startup.cs

services.AddMvc()
    .AddApplicationPart(typeof(MyApp.Core.RazorViewRenderer).GetTypeInfo().Assembly)
    .AddViewLocalization(LanguageViewLocationExpanderFormat.Suffix)
    .AddDataAnnotationsLocalization();

services.Configure<RazorViewEngineOptions>(o => {
    o.ViewLocationFormats.Add("/RazorTemplates/{0}" + RazorViewEngine.ViewExtension);
    o.FileProviders.Add(new PhysicalFileProvider(AppContext.BaseDirectory));
});

RazorViewRenderer.cs:

RazorViewRenderer.cs:

public async Task<string> RenderAsync<TModel>(string name, TModel model) {
    var actionContext = GetDefaultActionContext();
    var viewEngineResult = _viewEngine.FindView(actionContext, "Template1", true);

    if (!viewEngineResult.Success) {
        throw new InvalidOperationException($"View '{name}' cannot be found."); //Craches here.
    }

    var view = viewEngineResult.View;
    using (var output = new StringWriter()) {
        var viewContext = new ViewContext(actionContext, view,
            new ViewDataDictionary<TModel>(
                metadataProvider: new EmptyModelMetadataProvider(),
                modelState: new ModelStateDictionary()) {
                Model = model
            },
            new TempDataDictionary(
                actionContext.HttpContext,
                _tempDataProvider),
            output,
            new HtmlHelperOptions());

        await view.RenderAsync(viewContext);
        return output.ToString();
    }
}

注意:RazorLight不是一个选项.它不支持HTML帮助器，也完全不支持本地化.

Note: RazorLight is not an option. It does not support Html helpers and it does not support localization at all.

推荐答案

使用GetView()而不是FindView()解决了我的问题.

Solved my problem using GetView() instead of FindView().

此外，本地化也被打破.我必须使用IViewLocalizer的实现，因为在GitHub上查看Microsoft的代码后，IViewLocalizer使用了IHostingEnvironment中指定的程序集，该程序集设置为MyApp.Rest而不是MyApp.Core.

Also, localization was broken. I had to use my own implementation of IViewLocalizer since looking at Microsoft's code on GitHub, IViewLocalizer uses the assembly specified in IHostingEnvironment, which was set to MyApp.Rest instead of MyApp.Core.
