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

        return this.http.get<AccessData>(this.API_URL + this.API_ENDPOINT_LOGIN + '?' + this.util.urlParam(credential)).pipe(
            map((result: any) => {

                    return result.pop();
                }
