Angular 跨域

https://github.com/angular/an...

假如待请求的接口服务器为 https://xxx.xxxxxxx.com/api/c...

项目根目录
proxy.config.json
target 为接口服务器

{"/api": {"target": "https://xxx.xxx.com/api","changeOrigin": true,"secure": false,"logLevel": "debug","pathRewrite": {"^/api": ""}}
}

export class AuthenticationService implements AuthService {API_URL = '/api/';API_ENDPOINT_LOGIN = 'card/Login';public login(credential: Credential): Observable<any> {// Expecting response from API// tslint:disable-next-line:max-line-length// {"id":1,"username":"admin","password":"demo","email":"admin@demo.com","accessToken":"access-token-0.022563452858263444","refreshToken":"access-token-0.9348573301432961","roles":["ADMIN"],"pic":"./assets/app/media/img/users/user4.jpg","fullname":"Mark Andre"}return this.http.get<AccessData>(this.API_URL + this.API_ENDPOINT_LOGIN + '?' + this.util.urlParam(credential)).pipe(map((result: any) => {if (result instanceof Array) {return result.pop();}return result;}),tap(this.saveAccessData.bind(this)),catchError(this.handleError('login', [])));}
}
