我有metronic_v5.5.2 Angular版本，我正在尝试将其Angular版本与我的后端API集成。
由于我对这一切还很陌生，所以现在问题出在我的代理配置上，该配置无法按照我的期望工作。
以下是proxyconfig.json文件的代码
{
"/api": {
"target": "https://localhost:5001",
"secure": false,
"changeOrigin": true,
"logLevel": "debug"
}
}
但是在浏览器的控制台中，此请求实际上是路由到返回401错误的URL http://localhost:4200/api/auth/login。我无法通过点击按钮到达网址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);
});
}
}
函数对authdb导出类的代码进行了打击，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，并向服务目标添加了proxyConfig选项即可完成这项工作。
在服务内转到angular.json->，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，我是从here那里得到的

您说您是新手，所以让我先解释一些简单的事情。
当您调用http.post时，第一个参数是将被联系的URL。所以：
this.http.post(this.baseUrl + 'login', ...
将成为
this.http.post('api/auth/login', ...
因为您设置了baseUrl并添加了“登录”：
baseUrl = 'api/auth/';
但是您的代码没有说要使用哪个协议（http或https），也没有说要调用哪个domain：port（例如http://mydomain:port/api/auth/login）。
因此，Angular将默认为“ http”以及IT使用的域和端口，即localhost：4200。这样您的请求将变为：
http://localhost:4200/api/auth/login
这就是为什么您在控制台中看到它的原因。 Angular完全忽略了您的代理文件。我认为原因是名称或位置（通常应该在项目的根文件夹中），或者您没有告诉Angular加载它。
您需要告诉Angular在启动时实际使用它。因此，在package.json中，您需要这样的内容：
"start": "ng serve --proxy-config proxyconfig.json"
这告诉Angular-CLI，当您使用npm run start（或仅使用npm start）命令启动应用程序时，它应该从根文件夹中的json文件加载代理数据。
我建议您也阅读this tutorial。
此外，我认为您的proxyconfig中缺少/*：
{
"/api/*": {
"target": "http://localhost:5001",
"secure": false,
"changeOrigin": true,
"logLevel": "debug"
}
}

我花了几个小时才能将POST / api / auth / login的错误路由修复到您提供的映像中的https://localhost:5001上。
以下配置可将POST / api / auth / login的路由固定为https://localhost:5001/api/auth/login。
{
"/api": {
"target": "https://localhost:5001/api",
"changeOrigin": true,
"logLevel": "debug",
"pathRewrite": { "^/api" : "" }
}
}

在ng服务中添加“ --ssl”参数：
"start": "ng serve --proxy-config proxyconfig.json --ssl",
因为您要建立安全的连接：
"target": "https://localhost:5001",

要在Angular中配置代理，请执行以下步骤-
步骤1 。在存在package.json文件的有角根文件夹中，创建“ proxy.conf.json”并添加以下代码-
{
"/api/*": {
"target": "http://xxx.xxx.xxx.xxx:80/api/", // API URL or any URL for Proxy
"secure": false,
"logLevel": "debug",
"changeOrigin": true
}
}
第2步。然后更新angular.json文件，在架构师->服务->构建器->选项-
中添加属性“ proxyConfig”属性"projects": {
...
"angularPracticeProj": {
"projectType": "application",
"schematics": {},
...
"architect": {
...
"serve": {
...
"builder": "@angular-devkit/build-angular:dev-server",
"options": {
"browserTarget": "angularPracticeProj:build",
"proxyConfig": "proxy.conf.json" <==== angular proxy
},
...
}
...
}
}
}
如果您使用的是NodeJS / ExpressJS REST API，请从其中加载nodejs快递的位置更新app / root文件-
第3步（可选）。在定义了应用程序根目录的nodejs或ExpressJS根文件中，添加以下代码-
const app = express();
// angular app set as start
app.use(express.static(process.cwd() + "/../dist/angularPracticeProj/")); <= angular project's published/dist index file path
app.get('/', (req, res) => {
res.sendFile(process.cwd() + "/../dist/angularPracticeProj/index.html") <= angular project's published/dist index file path
});
