asp.net-mvc – 如何将asp.net mvc视图渲染为angular 2？

<side-bar></side-bar>
<action-bar></action-bar>

@{
    Html.RenderPartial("_SuperLegacyPartialView");   
}

我想出了一个满足我当时需求的解决方案.我正在使用带有WebPack的angular-cli,这符合我的需求.我不明白我见过的所有使用“templateUrl：’/ Template / Index’”的例子,其中路径是MVC视图的路径.这根本不起作用,因为在WebPack创建的任何捆绑视图中都找不到路径.也许那些人没有使用angular-cli和WebPack.

这个stackoverflow的答案–How can I use/create dynamic template to compile dynamic Component with Angular 2.0?在创建以下指令时非常有用.该指令将获取mvc局部视图的输出并进行编译.它允许发生Razor /服务器逻辑,并且还可以编译一些角度.虽然,实际上包含此MVC部分内的其他组件是有问题的.如果你这样做,请让我知道你做了什么.在我的情况下,我只需要服务器渲染,并将其放置在我的Angular 2水疗中心的确切位置.

MvcPartialDirective

import {
  Component,Directive,NgModule,Input,ViewContainerRef,Compiler,ComponentFactory,ModuleWithComponentFactories,ComponentRef,ReflectiveInjector,OnInit,OnDestroy
} from '@angular/core';

import { RouterModule }  from '@angular/router';
import { CommonModule } from '@angular/common';
import {Http} from "@angular/http";
import 'rxjs/add/operator/map';

export function createComponentFactory(compiler: Compiler,metadata: Component): Promise<ComponentFactory<any>> {
  const cmpClass = class DynamicComponent {};
  const decoratedCmp = Component(metadata)(cmpClass);

  @NgModule({ imports: [CommonModule,RouterModule],declarations: [decoratedCmp] })
  class DynamicHtmlModule { }

  return compiler.compileModuleAndAllComponentsAsync(DynamicHtmlModule)
    .then((moduleWithComponentFactory: ModuleWithComponentFactories<any>) => {
      return moduleWithComponentFactory.componentFactories.find(x => x.componentType === decoratedCmp);
    });
}

@Directive({ selector: 'mvc-partial' })
export class MvcPartialDirective implements OnInit,OnDestroy {
  html: string = '<p></p>';
  @Input() url: string;
  cmpRef: ComponentRef<any>;

  constructor(private vcRef: ViewContainerRef,private compiler: Compiler,private http: Http) { }

  ngOnInit() {
    this.http.get(this.url)
      .map(res => res.text())
      .subscribe(
        (html) => {
          this.html = html;
          if (!html) return;

          if(this.cmpRef) {
            this.cmpRef.destroy();
          }

          const compMetadata = new Component({
            selector: 'dynamic-html',template: this.html,});

          createComponentFactory(this.compiler,compMetadata)
            .then(factory => {
              const injector = ReflectiveInjector.fromResolvedProviders([],this.vcRef.parentInjector);
              this.cmpRef = this.vcRef.createComponent(factory,injector,[]);
            });
        },err => console.log(err),() => console.log('MvcPartial complete')
      );

  }

  ngOnDestroy() {
    if(this.cmpRef) {
      this.cmpRef.destroy();
    }
  }
}

在some-component.html中(假设您的mvc应用程序与您的spa共享域)

<mvc-partial [url]="'/stuffs/mvcstuff'"></mvc-partial>

MvcStuff.cshtml

@{
    ViewBag.Title = "This is some MVC stuff!!!";
}
<div>
    <h2>MVC Stuff:</h2>
    <h4>@ViewBag.Title</h4>
    <h2>Angular Stuff:</h2>
    <h4>{{1 + 1}}</h4>
</div>

在StuffsController.cs中

public PartialViewResult MvcStuff() => PartialView();
