预检响应的oauth / token的HTTP状态代码无效401

我已经在Spring Boot中实现了针对CORS的过滤器,代码如下:-

@SpringBootApplication

@Component

public class Application implements Filter {

public static void main(String[] args) {

SpringApplication.run(Application.class, args);

}

@Override

public void init(FilterConfig filterConfig) throws ServletException {

}

@Override

public void doFilter(ServletRequest servletRequest, ServletResponse servletResponse, FilterChain filterChain) throws IOException, ServletException {

HttpServletRequest request = (HttpServletRequest) servletRequest;

HttpServletResponse response = (HttpServletResponse) servletResponse;

response.setHeader("Access-Control-Allow-Origin", "*");

response.setHeader("Access-Control-Allow-Credentials", "true");

response.setHeader("Access-Control-Allow-Methods", "POST, GET, OPTIONS, DELETE");

response.setHeader("Access-Control-Max-Age", "3600");

response.setHeader("Access-Control-Allow-Headers", "Content-Type, Accept, X-Requested-With, remember-me");

filterChain.doFilter(servletRequest, servletResponse);

}

@Override

public void destroy() {

}

}

为了从oauth2获取access_token我已经从angularjs创建了以下对象:

 {"url":"http://localhost:8080/oauth/token?grant_type=client_credentials&client_id=clientId&client_secret=clientSecret","headers":{"Authorization":"Basic token_value"},"withCredentials":true,"method":"POST"}

我在服务器上遇到以下错误:-

OPTIONS url... 401() Response for preflight has invalid HTTP status code 401

我已经在堆栈溢出中寻找类似问题的解决方案,但都没有解决我的问题。有人可以帮忙吗?

回答:

请阅读有关预检要求的更多信息。

他们只是建议浏览器(如果服务器支持跨域请求)。对此类OPTIONS请求的响应应该很好(即<400)。

我认为该语句filterChain.doFilter(servletRequest,servletResponse);正在进一步传递请求,而不是返回响应。
