SpringCloud Zuul过滤器实现登陆鉴权代码实例

SpringCloud Zuul过滤器实现登陆鉴权代码实例

1.新建一个filter‘包

2.新建一个类，实现ZuulFilter，重写里面的方法

3.在顶部类添加注解，@Component，让Spring扫描

/**

* 登陆过滤器

*/

@Component

public class LoginFilter extends ZuulFilter {

@Override

public String filterType() { //前置过滤器

return PRE_TYPE;

}

@Override

public int filterOrder() { //过滤器顺序，越小越先执行

return 3;

}

@Override

public boolean shouldFilter() { //过滤器是否生效

RequestContext requestContext = RequestContext.getCurrentContext();

HttpServletRequest request = requestContext.getRequest();

System.out.println(request.getRequeshttp://tURI());

System.out.println(request.getRequestURL());

if ("/apizuul/order/api/v1/order/save".equalsIgnoreCase(request.getRequestURI())){ //拦截

return true;

bGNqVnbEf}

return false;

}

/**

* 业务逻辑

* @return

* @throws ZuulException

*/

@Override

public Object run() throws ZuulException {

System.out.println("拦截...");

RequestContext requestContext = RequestContext.getCurrentContext();

HttpServletRequest request = requestContext.getRequest();

String token = request.getHeader("token");

if (StringUtils.isBlank(token)){

token = request.getParameter("token");

}

//登陆校验逻辑 jwt生成token

if (StringUtils.isBlank(token)){

requestContext.setSendZuulResponse(false); //不会往下执行

requestContext.setResponseStatusCode(HttpStatuhttp://s.UNAUTHORIZED.value());

}

return null;

}
