身份验证失败重定向请求参数不起作用 [英] Authentication failure redirect with request params not working
问题描述
我正在尝试配置我自己的成功和身份验证失败处理程序.在身份验证失败时,我想使用请求参数重定向回我的登录页面,此参数的存在将在我的登录页面上输出错误消息.然而,尽管出错时我被重定向回我的登录页面,但请求参数始终为 null
.
I am trying to configure my own success and authentication failure handlers. On authentication failure I want to redirect back to my login page with a request parameter, the presence of this parameter will output the error message on my login page. However although on error I am getting redirected back to my login page, the request parameter is always null
.
代码如下:
protected void configure(HttpSecurity http) throws Exception {
http
.csrf().disable()
.authorizeRequests()
.antMatchers("/").permitAll()
.antMatchers("/login").permitAll()
.anyRequest().authenticated()
.and()
.formLogin()
.loginPage("/login.html").permitAll()
.usernameParameter("username")
.passwordParameter("password")
.loginProcessingUrl("/login")
.successHandler(successHandler())
.failureHandler(handleAuthenticationFailure());
}
@Autowired
@Override
protected void configure(AuthenticationManagerBuilder auth) throws Exception {
//database checks
}
};
}
/**
* Authentication success handler defines action when successfully authenticated
* @return
*/
@Bean
public AuthenticationSuccessHandler successHandler(){
return new AuthenticationSuccessHandler() {
@Override
public void onAuthenticationSuccess(HttpServletRequest httpRequest, HttpServletResponse httpResponse, Authentication authentication)
throws IOException, ServletException {
// custom auth success here
httpResponse.setStatus(HttpServletResponse.SC_OK);
SavedRequest savedRequest = (SavedRequest) httpRequest.getSession().getAttribute("SPRING_SECURITY_SAVED_REQUEST");
httpResponse.sendRedirect(savedRequest.getRedirectUrl());
}
};
}
@Bean
public AuthenticationFailureHandler handleAuthenticationFailure() {
return new SimpleUrlAuthenticationFailureHandler() {
@Override
public void onAuthenticationFailure(HttpServletRequest httpRequest, HttpServletResponse httpResponse,
AuthenticationException authenticationException) throws IOException, ServletException {
// custom failure code here
setDefaultFailureUrl("/login.html?error=fail");
super.onAuthenticationFailure(httpRequest, httpResponse, authenticationException);
}
};
}
推荐答案
试试这个:
@Override
public void onAuthenticationFailure(HttpServletRequest request, HttpServletResponse response, AuthenticationException exception) throws IOException, ServletException {
// .......
response.sendRedirect("/login.html?error=fail");
}
更新:
将/login.html?error=fail"添加到 authorizeRequests() 部分非常重要,否则控制器将不会获取错误参数.
It's really important that the "/login.html?error=fail" is added to an authorizeRequests() section otherwise the controller won't pick up the error parameter.
将 .antMatchers("/login").permitAll()
替换为 .antMatchers("/login**").permitAll()
