代理配置未在角工作6

问题描述 投票：5回答：3

我已经metronic_v5.5.2角版本，我想它的角版本与我的后端集成的API。

由于我很新的这一切，现在的问题是具有根据我的期望不工作我的代理配置。

以下是proxyconfig.json文件的代码

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

Image is showing that the request is routing to the URL "https://localhost:5001/api/auth/login" POST /api/auth/login -> https://localhost:5001

但是，在浏览器的控制台这一要求实际上是路由到URL http://localhost:4200/api/auth/login它会返回401错误。我无法路线上点击按钮来的网址：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出口类的代码被给予打击，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'
    );
  }
}

我有同样的问题，增加proxyConfig选项的服务目标所做的工作。

转到angular.json - >全球范围内服务中添加键值：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，我得到这个从here

你说你是新来这个，所以让我先解释一下简单的东西。

当你调用http.post第一个参数是将要连接的URL。所以：

this.http.post(this.baseUrl + 'login', ...

会变成

this.http.post('api/auth/login', ...

因为你设置的baseUrl并添加“登录”：

baseUrl = 'api/auth/';

但您的代码不说要使用的协议（HTTP或HTTPS），也没有哪域：端口上调用（如http://mydomain:port/api/auth/login）。

因此角将默认为“HTTP”和域，它正在使用的端口，这为localhost：4200。所以，你的要求就变成了：

http://localhost:4200/api/auth/login

这就是为什么你看到，在控制台中。角度是完全无视你的代理文件。我想原因是在该名称或位置（通常它应该是在你的项目的根文件夹），或者你还没有告诉角加载它。

你需要告诉角度实际使用它时，它启动。所以在你的package.json需要的是这样的：

"start": "ng serve --proxy-config proxyconfig.json"

这告诉角CLI，当你使用npm run start（或只是npm start）命令来启动应用程序，它应该从根文件夹JSON文件加载代理数据。

我劝读this tutorial也。

另外，我觉得你有/*从proxyconfig丢失：

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

我花了几个小时来解决POST / API / auth /中登录的不正确路由https://localhost:5001这是你提供的形象。

以下配置可修复POST / API / auth /中登录到https://localhost:5001/api/auth/login路由。

{
    "/api": {
        "target": "https://localhost:5001/api",
        "changeOrigin": true,
        "logLevel": "debug",
        "pathRewrite": { "^/api" : "" }
    }
}
