Question

启用csrf时，在Spring安全配置文件中的Spring应用程序中 (<security:csrf/>)

并尝试提交登录表单，然后出现（或）访问被拒绝页面403

(Invalid CSRF Token 'null' was found on the request parameter '_csrf' or header 'X-CSRF-TOKEN'.)异常（当访问被拒绝处理程序不存在时）

“但如果我没有在spring安全配置文件中启用CSRF，那么一切都能正常运行。”

启用CSRF时的代码

pom.xml（所有版本）

<properties>
    <spring.version>3.2.8.RELEASE</spring.version>
    <spring.security.version>3.2.3.RELEASE</spring.security.version>

输出：

    HTTP Status 403 - Access is denied

Username : ${username} 
You do not have permission to access this page!

请帮忙。

解决方案

控制器：

@RequestMapping(value={"/","/loginSuccess"},method=RequestMethod.GET)
public ModelAndView loginSuccess()

的web.xml

    <welcome-file-list>
      <welcome-file>login.jsp</welcome-file>
    </welcome-file-list>

由于默认页面

Answer 1

我认为您提交表单后正在执行ajax请求。在这种情况下，您必须在标题中传递csrf标记。

等等，

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);

为了只为特定网址启用csrf，您可以执行类似这样的操作

@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");
            }
        });
    }
}

在Spring Security中启用CSRF时，拒绝访问403
