Question

我创建了一个Angular前端，现在我希望它与我的PHP后端进行通信。运行ng服务时，我收到警告：./node_modules/@angular/http/src/backends/xhr_backend.js 167：24-52中的警告 “在'@ angular / platform-browser'中找不到导出' platform_browser_private '。Chrome显示相同的警告和错误：错误TypeError：无法读取未定义的属性'getDOM' 我该如何解决？

App.component.html：

var data = _moviesDbContext.Movies.Include(x => x.Ratings)
            .Select(x => new {
                Id = x.Id,
                Title = x.Title,
                Average = (int?)x.Ratings.Average(y => y.RatingValue)
        }).OrderByDescending(x => x.Average).ThenBy(x => x.Title).Take(5).ToList();

App.component.ts：

<form class="example-form">
  <mat-form-field class="example-full-width">
    <input type="text" placeholder="Pick one" aria-label="Number" matInput [formControl]="myControl" [matAutocomplete]="auto">
    <mat-autocomplete #auto="matAutocomplete">
      <mat-option *ngFor="let option of filteredOptions | async" [value]="option">
        {{option}}
      </mat-option>
    </mat-autocomplete>
  </mat-form-field>
</form>

App.module.ts：

 import {Component, OnInit} from '@angular/core';
import {FormControl} from '@angular/forms';
import {Observable} from 'rxjs';
import {map, startWith} from 'rxjs/operators';
import { ServerService } from './server.service';

/**
 * @title Filter autocomplete
 */
@Component({
  selector: 'app-root',
  templateUrl: 'app.component.html',
  styleUrls: ['app.component.css'],
})
export class AppComponent implements OnInit {
  myControl = new FormControl();
  megyek: string[];
  filteredOptions: Observable<string[]>;
  constructor(private serverService: ServerService) {}

  ngOnInit() {
    this.serverService.getMegyek()
    .subscribe(
      (megyek: any[]) => this.megyek = megyek,
      (error) => console.log(error)
    );
    this.filteredOptions = this.myControl.valueChanges
      .pipe(
        startWith(''),
        map(value => this._filter(value))
      );
  }

  private _filter(value: string): string[] {
    const filterValue = value.toLowerCase();

    return this.megyek.filter(option => option.toLowerCase().includes(filterValue));
  }
}

Server.service.ts：

import { BrowserModule } from '@angular/platform-browser';
import { NgModule } from '@angular/core';
import { ReactiveFormsModule, FormsModule } from '@angular/forms';
import { ServerService } from './server.service';
import { HttpModule } from '@angular/http';


import { AppComponent } from './app.component';

import {
  MatButtonModule,
  MatFormFieldModule,
  MatInputModule,
  MatRippleModule,
  MatAutocompleteModule,
} from '@angular/material';

import {BrowserAnimationsModule} from '@angular/platform-browser/animations';
import { Server } from 'selenium-webdriver/safari';

@NgModule({
  exports: [
    MatButtonModule,
    MatFormFieldModule,
    MatInputModule,
    MatRippleModule,
    MatAutocompleteModule,
    ReactiveFormsModule,
    BrowserAnimationsModule,
    FormsModule,
    HttpModule
  ],
  declarations: [],
  imports: []
})
export class MaterialModule {}

@NgModule({
  declarations: [
    AppComponent
  ],
  imports: [
    MaterialModule,
    BrowserModule,
  ],
  providers: [ServerService],
  bootstrap: [
    AppComponent,
  ],
  schemas: [],
})
export class AppModule { }

如何使我的Angular前端与PHP后端通信？
