python之Django 和 Angular 2 templateUrl

我决定将现有的 Angular 2 应用程序集成到我的 Django REST 项目中。

1. 为我的前端创建带有静态文件夹的 Django 应用程序:

   urls.py:

   from django.conf.urls import url 
   from frontend import views 
   from django.conf import settings 
   from django.conf.urls.static import static 
    
    
   urlpatterns = [ 
       url(r'^$', views.index,  name='index'), 
   ] + static(settings.STATIC_URL, document_root=settings.STATIC_ROOT) 
   

   views.py:

   from django.shortcuts import render 
    
   def index(request): 
       """ 
       Renders the Angular2 SPA 
       """ 
       return render(request, template_name='index.html') 
   

2. 将我的 Angular 2 应用移至前端静态文件夹

3. 在我的设置中添加静态设置:

   STATIC_URL = '/static/' 
   STATICFILES_DIRS = [ 
       os.path.join(BASE_DIR, 'frontend', 'static'), 
   ] 
    
   STATIC_ROOT = os.path.join(BASE_DIR, 'static') 
   

4. 修改 index.html:

   <html> 
     <head> 
       <base href="/"> 
       <title>PhotoHub</title> 
       <meta charset="UTF-8"> 
       <meta name="viewport" content="width=device-width, initial-scale=1"> 
       {% load staticfiles %} 
    
    
       <link rel="stylesheet" href="{% static "node_modules/bootstrap/dist/css/bootstrap.min.css" %}"> 
       <link href="{% static "bower_components/font-awesome/css/font-awesome.min.css" %}" rel="stylesheet" /> 
       <link href="{% static "bower_components/alertify.js/themes/alertify.core.css" %}" rel="stylesheet" /> 
       <link href="{% static "bower_components/alertify.js/themes/alertify.bootstrap.css" %}" rel="stylesheet" /> 
       <link rel="stylesheet" href="{% static "styles.css" %}"> 
    
       <script src="{% static "bower_components/jquery/dist/jquery.min.js" %}"></script> 
       <script src="{% static "node_modules/bootstrap/dist/js/bootstrap.min.js" %}"></script> 
       <script src="{% static "bower_components/alertify.js/lib/alertify.min.js" %}"></script> 
       <!-- 1. Load libraries --> 
        <!-- Polyfill(s) for older browsers --> 
       <script src="{% static "node_modules/core-js/client/shim.min.js" %}"></script> 
       <script src="{% static "node_modules/zone.js/dist/zone.js" %}"></script> 
       <script src="{% static "node_modules/reflect-metadata/Reflect.js" %}"></script> 
       <script src="{% static "node_modules/systemjs/dist/system.src.js" %}"></script> 
       <!-- 2. Configure SystemJS --> 
       <script src="{% static "systemjs.config.js" %}"></script> 
       <script> 
         System.import('app').catch(function(err){ console.error(err); }); 
       </script> 
     </head> 
     <!-- 3. Display the application --> 
     <body> 
       <photohub></photohub> 
     </body> 
   </html> 
   

5. 在 systemjs.config.js 中进行更改:

   (function (global) { 
     System.config({ 
       //static 
       defaultJSExtensions: true, 
       paths: { 
         // paths serve as alias 
         'npm:': 'static/node_modules/' 
       }, 
       // map tells the System loader where to look for things 
       map: { 
         app: 'static/dist', 
         // angular bundles 
         '@angular/core': 'npm:@angular/core/bundles/core.umd.js', 
         '@angular/common': 'npm:@angular/common/bundles/common.umd.js', 
         '@angular/compiler': 'npm:@angular/compiler/bundles/compiler.umd.js', 
         '@angular/platform-browser': 'npm:@angular/platform-browser/bundles/platform-browser.umd.js', 
         '@angular/platform-browser-dynamic': 'npm:@angular/platform-browser-dynamic/bundles/platform-browser-dynamic.umd.js', 
         '@angular/http': 'npm:@angular/http/bundles/http.umd.js', 
         '@angular/router': 'npm:@angular/router/bundles/router.umd.js', 
         '@angular/forms': 'npm:@angular/forms/bundles/forms.umd.js', 
         // other libraries 
         'rxjs':                      'npm:rxjs', 
         'angular-in-memory-web-api': 'npm:angular-in-memory-web-api', 
       }, 
       // packages tells the System loader how to load when no filename and/or no extension 
       packages: { 
         app: { 
           main: './main.js', 
           defaultExtension: 'js' 
         }, 
         rxjs: { 
           defaultExtension: 'js' 
         }, 
         'angular-in-memory-web-api': { 
           main: './index.js', 
           defaultExtension: 'js' 
         } 
       } 
     }); 
   })(this); 
   

TypeScript 文件在 /dist 中编译，模板保留在 /app 中。当我使用两个不同的服务器时，templateUrl 的路径如下所示:

templateUrl: './app/app.component.html' 

现在我正尝试以这种方式声明 templateUrl，但它不起作用:

templateUrl: '{{ STATIC_URL }}' + '/app/app.component.html' 

现在如何处理模板 url？

响应:

"GET /app/components/login/login.component.html HTTP/1.1" 404 2601
Not Found: /app/app.component.html

JavaScript 文件加载良好:

"GET /app/components/login/login.component.html HTTP/1.1" 404 2601
Not Found: /app/components/register/register.component.html

请您参考如下方法:

这个解决的问题:

templateUrl: 'static/app/app.component.html'
