Angular 7-从DB呈现innerHTML标记

import { Component, OnInit } from '@angular/core';
import { DataService } from 'your-data-service'; // 你的数据服务

@Component({
  selector: 'app-data',
  template: '<div [innerHTML]="dynamicHTML"></div>',
})
export class DataComponent implements OnInit {
  dynamicHTML: string;

  constructor(private dataService: DataService) { }

  ngOnInit() {
    this.getData();
  }

  getData() {
    this.dataService.getData().subscribe((data: string) => {
      this.dynamicHTML = data;
    });
  }
}

import { Injectable } from '@angular/core';
import { HttpClient } from '@angular/common/http';

@Injectable({
  providedIn: 'root'
})
export class DataService {
  private apiUrl = 'your-api-url'; // 你的API地址

  constructor(private http: HttpClient) { }

  getData() {
    return this.http.get<string>(this.apiUrl);
  }
}
