request.getRequestURL()相关的问题

[sandy刘]

我在spring cloud zuul的统一异常处理中打印了请求地址request.getRequestURL()，但是从日志中看到，有时候这个请求地址居然是http://www.baidu.com/error，这怎么搞的，有大神也遇到过吗？下面是异常信息

整个项目全文搜都没有www.baidu.com，但是日志里有时候就是会出现来自http://www.baidu.com/error的报错信息，而且是被异常处理捕获了的，难道是服务被攻击了

通过浏览器发起请求来访问你的服务，request.getRequestURL()获取到的是浏览器地址栏输入的请求链接（不包括请求参数），这个链接不一定是真实有效的。比如，你可以修改自己电脑的hosts文件，将www.baidu.com指向你的服务的IP，然后访问http://www.baidu.com/xxx就会请求到你的服务，request.getRequestURL()获取到的自然就变成这样了。

多谢，这点的确说得通！

查一下配置文件看看吧，如application.yml，看看有没有http://www.baidu.com/error相关的
