Question

我制作了一个通用的拦截器，用于为每个请求在标头中打入授权令牌。令牌已从Spring Boot后端正确保存到会话存储中。相同的令牌在Postman中工作，但在Angular服务中会失败（从Spring Boot调用REST API时）。在浏览器控制台中，它显示HTTP 500 invalid token任何帮助。

JwtInterceptor.ts

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

@Injectable()
export class JwtInterceptor {

    constructor() {}

    intercept(request: HttpRequest<any>, next: HttpHandler): Observable<HttpEvent<any>> {
        // add authorization header with jwt token if available
        // tslint:disable-next-line:prefer-const
        const token = sessionStorage.getItem('token');
        if (token) {
            request = request.clone({
                headers: request.headers.set('Authorization', 'Bearer ' + token)
            });
        }
        return next.handle(request);
    }

}

Answer 1

令牌可能已过期这就是我在代码中所做的

    const myHeaders = new Headers();
    myHeaders.append("Content-Type", "application/json");
    myHeaders.append("Authorization",localStorage.getItem("token") );

Angular 5 JWT总是说“无效令牌”
