Spring Security Jwt 令牌在请求表单角度时允许所有选项方法

Question

不知道怎么回事，网上到处查了一下，好像和我的一样，但是遇到了这个问题：

我正在使用带有 Angular 拦截器的 HttpClient 请求我的 Angular 应用程序来 setHeader，因为我的 Java Rest API 正在使用 JWT 进行身份验证，并且在标头中需要一个令牌，因此它将获取并验证用户请求，因为 Angular 拦截器不工作适当地。我在 Java 端获取 null 作为令牌并出现错误。请帮我解决这个问题。

最后我发现它可能是弹簧安全问题，因为我调试并发现选项请求所有过滤器并且它没有标头，因此它显示令牌并抛出异常 如果选项方法请求绕过并允许那么可能是我的问题将解决

Angular 拦截器代码

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



            console.log("i am inside");

            request = request.clone({
                setHeaders: {
                    Accept: 'application/json',
                    Authorization: `Bearer ${localStorage.getItem('token')}`
                }
            });


        return next.handle(request);
    }
}

Angular 服务

import { Injectable } from '@angular/core';
import { HttpClient } from '@angular/common/http';
import { Observable } from 'rxjs';

@Injectable({
  providedIn: 'root'
})
export class ServiceService {

  constructor(private http: HttpClient) { }

  api_user_url = 'http://localhost:8095';

  getAllApiUsers(): Observable<any> {
    return this.http.get(this.api_user_url + "/allUser");
  }

  setUserLogin(obj):Observable<any>{

    return this.http.post(this.api_user_url +"/login", obj);
  }
}

调用算法

public getAllUserList() {

    console.log("I am calling");

    this.service.getAllApiUsers()
      .subscribe(data => {
        this.alluser = data;
        console.log(data);

      })
  }

Spring Boot Java 控制台错误

Answer 1

Angular 拦截器看起来不错，但在您的浏览器控制台中有 CORS policy 错误。您的 Angular 应用在​​端口 4200 上运行，而您的后端在 8095（不同主机）上运行。

我不知道spring-boot，但是在查看文档后，您应该在后端应用程序中添加一些 cors 策略（生产和开发环境不同）：

您可以在这里阅读更多内容：https://spring.io/guides/gs/rest-service-cors/

现在您对/allUser 的请求未发送...在消除 CORS 问题后，一切都应该正常工作
