我是来自 rails 的 Angular 社区的新手；我正在一个网站上工作，我可以在其中发布我的客户网站的案例研究。到目前为止，我很喜欢 angular，但我遇到了一个让我有点担心的问题。我似乎无法使用超链接来引用任何项目的问题。例如，如果您单击此应用程序将返回 404 状态，但如果您从根页面开始，一切都会运行没有问题。

我尝试过的解决方案

  1. 在加载页面之前向路由添加解析器以获取数据；它可以工作，但仍然没有超链接。

谁能帮我弄清楚我错过了什么或做错了什么？

以下是我的代码；任何帮助，将不胜感激

  1. 项目服务.ts

    import { AngularFirestore } from 'angularfire2/firestore';
    import { Observable, of } from 'rxjs';
    import { map,  } from 'rxjs/operators';
    import { Injectable } from '@angular/core';
    import { Project } from '../../models/project';
    import { HttpClient } from '@angular/common/http';
    import { Post } from '../post';
    
    
    
    
    @Injectable()
    
    export class ProjectService {
    
        ProjectListRef: Observable<any[]>;
        featuredProjectList: Observable<any[]>;
        posts: Array<Post>;
   
    
        constructor( private database: AngularFirestore, private http: HttpClient) {
            // Link For All Projects Page
            const allProjectsListLink = this.database.collection<Project>('projects', ref => ref.orderBy('company_name'));
    
    
    
            // Link For Featured Project Page
            const featuredProjectsListLink = this.database.collection<Project>('projects', ref => ref.limit(5));
    
    
    
this.ProjectListRef = allProjectsListLink.snapshotChanges()
            // using map pipe
            .pipe(map( actions => {
                return actions.map(a => {
                    // Get Document Data
                    const data = a.payload.doc.data() as Project;

                    // Get Document Id

                    const id = a.payload.doc.id;

                    return {id, ...data};

                });
            }));
    
      this.featuredProjectList = featuredProjectsListLink.snapshotChanges()
      // using map pipe
      .pipe(map( actions => {
      return actions.map(a => {
      // Get Document Data
      const data = a.payload.doc.data() as Project;

      // Get Document Id

      const id = a.payload.doc.id;

      return {id, ...data};

      });
      }));


      }


        getAllProjects() {
            return this.ProjectListRef;
        }
    
        getFeaturedProjects() {
            return this.featuredProjectList;
        }
    
        getProject(id: string) {
            console.log(id);
            return this.database.collection('projects').doc(id)
            .ref.get().then( doc => doc.data() );
          }
    
    }

              ngOnInit() {
            
                  // print out the data from the route resolver
                  this.route.data.pipe(
                    tap(console.log))
                    .subscribe(
                      data => this.project = data['project']

import { Observable } from 'rxjs';
import { Injectable } from '@angular/core';

您的角度代码没有任何错误。您面临的问题是 url 没有被重写为 index.html。您需要在 Firebase 设置 (firebase.json) 中进行配置。这是最简单和最常见的配置：

  "hosting": {
    "public": "dist",
    "rewrites": [
      {
        "source": "**",
        "destination": "/index.html"
      }
    ]
  }
}
