在Spring Security中启用CSRF时，访问被拒绝403 [英] When CSRF enable in Spring Security, Access denied 403
本文介绍了在Spring Security中启用CSRF时，访问被拒绝403的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
在我的Spring应用程序的spring安全配置文件中，启用csrf时
（< security：csrf />）
In my Spring application in spring security configuration file when csrf is enable
(<security:csrf/>)
并尝试提交登录表单，然后出现（或）
and try to submit login form then Access denied page 403 appear (or)
（无效的CSRF令牌'null在请求参数'_csrf'或标头'X-CSRF-TOKEN'上找到。）异常（当不存在拒绝访问处理程序时）
(Invalid CSRF Token 'null' was found on the request parameter '_csrf' or header 'X-CSRF-TOKEN'.) exception (when access-denied-handler not present)
但是，如果我没有在春季安全配置文件中启用CSRF，那么一切都会正常运行。
"But if I don't enable CSRF in spring security configuration file then everything work perfectly."
在启用CSRF时，这里是我的代码

输出：

请帮助。
解决方案
控制器：
@RequestMapping(value={"/","/loginSuccess"},method=RequestMethod.GET)
public ModelAndView loginSuccess()
web.xml
<welcome-file-list>
<welcome-file>login.jsp</welcome-file>
</welcome-file-list>
由于默认页面
推荐答案
我认为一旦提交表单，您正在执行ajax请求。在这种情况下，您必须在标题中传递csrf令牌。
I think you are doing an ajax request once you submit the form. In that case, you have to pass csrf token in the header.
类似
var token = $("meta[name='_csrf']").attr("content");
var header = $("meta[name='_csrf_header']").attr("content");
var headers ={};
headers[header]=token;
var headerObj = {};
headerObj['headers']=headers;
$http.post("http://xyz",request,headerObj);
为了仅对特定网址启用csrf，您可以执行以下操作
In order to enable csrf only for a particular url, You can do something like this
@EnableWebSecurity
@Configuration
public class SecurityConfig extends WebSecurityConfigurerAdapter {
@Override
protected void configure(HttpSecurity http) throws Exception {
http.csrf().requireCsrfProtectionMatcher(new RequestMatcher() {
@Override
public boolean matches(HttpServletRequest request) {
return request.getServletPath().contains("/xyz");
}
});
}
}
