angular - 代理配置在角度 6 中不起作用

Question

我有 metronic_v5.5.2 Angular 版本，我正在尝试将它的 Angular 版本与我的后端 API 集成。

由于我对这一切都很陌生，现在问题在于我的代理配置没有按照我的预期工作。

以下是proxyconfig.json文件的代码

{
    "/api": {
        "target": "https://localhost:5001",
        "secure": false,
        "changeOrigin": true,
        "logLevel": "debug"
    }
}

图片显示请求正在路由到 URL “https://localhost:5001/api/auth/login” POST /api/auth/login -> https://localhost:5001

但是在浏览器的控制台中，这个请求实际上是路由到返回 401 错误的 URL http://localhost:4200/api/auth/login 。我无法通过单击按钮路由到 url：https://localhost:5001/api/auth/login

以下是 HTML 代码

<!--begin::Form-->
<form class="m-login__form m-form" name="form" (ngSubmit)="f.form.valid && submit()" #f="ngForm" novalidate>
    <div class="form-group">
        <mat-form-field>
            <mat-label>Email</mat-label>
            <input matInput type="email" name="email" placeholder="Email address" autocomplete="off" [(ngModel)]="model.email" #email="ngModel" email="true" required>
        </mat-form-field>
    </div>
    <div class="form-group">
        <mat-form-field>
            <mat-label>Password</mat-label>
            <input matInput minlength="4" type="password" name="password" placeholder="Password" autocomplete="off" [(ngModel)]="model.password" #password="ngModel" required>
        </mat-form-field>
    </div>
</form>
<!--end::Form-->

<!--begin::Action-->
<div class="m-login__action m-login__action--fit">
    <a href="javascript:;" (click)="forgotPasswordPage($event)" class="m-link">
        <span translate="AUTH.GENERAL.FORGOT_BUTTON">Forgot Password?</span>
    </a>
    <m-spinner-button [options]="spinner" (click)="submit()">{{'AUTH.LOGIN.BUTTON' | translate}}</m-spinner-button>
</div>

以下是 login.component.ts 代码

submit() {
        this.spinner.active = true;
        if (this.validate(this.f)) {
            this.authServiceDb.logindb(this.model).subscribe(response => {
                    this.router.navigate(['/']);
                    this.alertify.success('Logged In Successfully');
                    this.spinner.active = false;
                    this.cdr.detectChanges();
            }, error => {
                this.alertify.error(error);
            });
        }
    }

功能 authdb 导出类的代码给出了打击，编辑

import { Injectable } from '@angular/core';
import { Http, Headers, RequestOptions, Response } from '../../../node_modules/@angular/http';
import { map, catchError } from 'rxjs/operators';
import { throwError } from '../../../node_modules/rxjs';
import { tokenNotExpired, JwtHelper } from 'angular2-jwt';

@Injectable({
    providedIn: 'root'
})
export class AuthdbService {
    baseUrl = 'api/auth/';
    userToken: any;
    decodedTokenn: any;
    jwtHelper: JwtHelper = new JwtHelper();
    constructor(private http: Http) { }
public logindb(model: any) {
    return this.http.post(this.baseUrl + 'login', model, this.requestOptions()).pipe(map((response: Response) => {
      const user = response.json();
      if (user) {
        localStorage.setItem('token', user.tokenString);
        this.decodedTokenn = this.jwtHelper.decodeToken(user.tokenString);
        this.userToken = user.tokenString;
      }
    })).pipe(catchError(this.handleError));
  }
  register(model: any) {
    return this.http.post(this.baseUrl + 'register', model, this.requestOptions()).pipe(catchError(this.handleError));
  }
  loggedIn() {
    return tokenNotExpired('token');
  }
  private requestOptions() {
    const headers = new Headers({
      'Content-type': 'application/json'});
    return new RequestOptions({headers: headers});
  }
  private handleError(error: any) {
    const applicationError = error.headers.get('Application-Error');
    if (applicationError) {
      return throwError(applicationError);
    }
    const serverError = error.json();
    let modelStateErrors = '';
    if (serverError) {
      for (const key in serverError) {
        if (serverError[key]) {
          modelStateErrors += serverError[key] + '\n';
        }
      }
    }
    return throwError(
      modelStateErrors || 'Server Eroor'
    );
  }
}

我遇到了同样的问题，向proxyConfig服务目标添加选项就可以了。

转到 angular.json -> 在服务中添加键：值对"proxyConfig": "proxy.conf.json"

像这样 -

"architect": {
  "serve": {
    "builder": "@angular-devkit/build-angular:dev-server",
    "options": {
      "browserTarget": "your-application-name:build",
      "proxyConfig": "proxy.conf.json"
    },

顺便说一句，我从这里得到这个
