springsecurity 如何实现通过GET请求也可以提交登录数据

Spring Security 默认情况下只支持 POST 方法提交登录数据。要支持 GET 方法提交登录数据,需要通过配置 `org.springframework.security.web.authentication.UsernamePasswordAuthenticationFilter` 过滤器的 `setPostOnly(false)` 方法来实现。
具体实现步骤如下:
1. 创建一个继承自 `UsernamePasswordAuthenticationFilter` 的类,重写其 `attemptAuthentication` 方法。
```java
public class CustomUsernamePasswordAuthenticationFilter extends UsernamePasswordAuthenticationFilter {
@Override
public Authentication attemptAuthentication(HttpServletRequest request, HttpServletResponse response)
throws AuthenticationException {
if (!"POST".equals(request.getMethod()) && !"GET".equals(request.getMethod())) {
throw new AuthenticationServiceException("Authentication method not supported: " + request.getMethod());
}
// 处理登录请求
// ...
}
}
```
2. 在 Spring Security 配置类中,将上述自定义的过滤器添加到过滤器链中,并设置 `setPostOnly(false)`。
```java
@Configuration
@EnableWebSecurity
public class SecurityConfig extends WebSecurityConfigurerAdapter {
@Autowired
private CustomUserDetailsService userDetailsService;
@Override
protected void configure(HttpSecurity http) throws Exception {
http.authorizeRequests()
.antMatchers("/login").permitAll()
.anyRequest().authenticated()
.and()
.formLogin()
.loginPage("/login")
.loginProcessingUrl("/login")
.and()
.logout()
.logoutUrl("/logout")
.and()
.csrf().disable()
.addFilterAt(customUsernamePasswordAuthenticationFilter(), UsernamePasswordAuthenticationFilter.class);
}
@Bean
public CustomUsernamePasswordAuthenticationFilter customUsernamePasswordAuthenticationFilter() throws Exception {
CustomUsernamePasswordAuthenticationFilter filter = new CustomUsernamePasswordAuthenticationFilter();
filter.setAuthenticationManager(authenticationManagerBean());
filter.setFilterProcessesUrl("/login");
filter.setPostOnly(false);
return filter;
}
@Override
protected void configure(AuthenticationManagerBuilder auth) throws Exception {
auth.userDetailsService(userDetailsService);
}
}
```
这样就可以通过 GET 请求提交登录数据了。但是,由于 GET 请求会将参数暴露在 URL 中,存在安全风险,建议还是使用 POST 请求。
