角度6-为什么在生产构建中缺少承载令牌(在dev-build中运行良好)

我使用的是Angular6,配置了一个HTTP拦截器,将承载令牌应用于传出请求。

• 在开发版本中( ng serve :-)

• ng serve --prod )请求在没有承载令牌的情况下发出。 :-(

我不知道为什么他们被排除在http请求之外。

我的生活没有什么不同 environment 文件夹。

我还应该看什么?

ng serve--生产 在当地也看到了同样的结果。

jwt拦截器:

import { Injectable } from '@angular/core';
import { HttpRequest, HttpHandler, HttpEvent, HttpInterceptor } from '@angular/common/http';
import { Observable } from 'rxjs';

@Injectable()
export class JwtInterceptor implements HttpInterceptor {
    intercept(request: HttpRequest<any>, next: HttpHandler): Observable<HttpEvent<any>> {

        // add authorization header with jwt token if available
        let currentUser = JSON.parse(localStorage.getItem('currentUser'));

        if (currentUser && currentUser.token) {
            request = request.clone({
                setHeaders: {
                    Authorization: `Bearer ${currentUser.token}`
                }
            });
            console.log('headers:', request.headers); // <---- I can see headers in console output
        }

        return next.handle(request);
    }
}

以下是我在控制台中看到的内容:
