公司运行的App 登陆-验证码短信接口,遭到大量的恶意攻击。处于安全的考虑,需要客户端api目前的一些接口加上验证签名的功能,以提高安全性。
现行的App之前也有过签名的秘钥在,后来出于性能考虑,验签功能并没有用上。所以并不是所有的接口都需要验签,只需要要在需要的接口及时加入验签功能即可。
我们运行的api项目,是基于Spring Cloud的一个项目,所以都是基于Spring Boot 的,版本是1.5.3
@Retention(RetentionPolicy.RUNTIME)
@Target(ElementType.METHOD)
@Documented
public @interface Signature {
String value() default "";
}
org.springframework.web.servlet.handler.HandlerInterceptorAdapter
的拦截器 SignatureInterceptor
这里我们只需要重写前置拦截的方法即可
public class SignatureInterceptor extends HandlerInterceptorAdapter {
private final static Logger logger = LoggerFactory.getLogger(SignatureInterceptor.class);
@Override
public boolean preHandle(HttpServletRequest request, HttpServletResponse response,
Object handler) throws Exception {
if (handler instanceof HandlerMethod) {
HandlerMethod hm = (HandlerMethod) handler;
Signature signature = hm.getMethodAnnotation(Signature.class);
if (signature == null) {
return true;
}
//验证签名的方法
ApiError result = checkSigature(request, response);
if (result == null) {
return true;
}
SimpleResponse simResponse = new SimpleResponse(result, request.getRequestURI());
String strResponseJson = JsonUtil.toJson(simResponse);
response.setContentType("application/json;charset=UTF-8");
try (OutputStream out = response.getOutputStream()) {
out.write(strResponseJson.getBytes("UTF-8"));
out.flush();
}
request.setAttribute(Constants.RESPONSE_BODY_STRING, strResponseJson);
return false;
}
return super.preHandle(request, response, handler);
}
@Configuration
public class WebMvcConfiguration extends WebMvcConfigurerAdapter{
@Bean
@Autowired
public ServletRegistrationBean dispatcherRegistration(DispatcherServlet dispatcherServlet){
ServletRegistrationBean dispatcherRegistration = new ServletRegistrationBean(dispatcherServlet);
dispatcherRegistration.addUrlMappings("*.do");
dispatcherRegistration.addUrlMappings("*.htm");
dispatcherRegistration.addUrlMappings("/*");
dispatcherRegistration.setLoadOnStartup(1);
return dispatcherRegistration;
}
/**
* 通过 @Bean 注入这个 拦截器
* @return
*/
@Bean
public HandlerInterceptor signatureInterceptor(){
return new SignatureInterceptor();
}
@Override
public void addInterceptors(InterceptorRegistry registry) {
// signatureInterceptor 定义 拦截的URL 的类型
registry.addInterceptor(signatureInterceptor()).addPathPatterns("/**")
.excludePathPatterns("/dss/**")
.excludePathPatterns("/mappings","/trace","/info","/metrics","/health","/env","/refresh","/configprops")
.excludePathPatterns("/archaius","/proxy.stream","/hystrix","/hystrix/**","/hystrix.stream")
.excludePathPatterns("/heapdump","/dump")
.excludePathPatterns("/error","/loggers","/loggers/**");
}
@Override
public void configureHandlerExceptionResolvers(List<HandlerExceptionResolver> exceptionResolvers) {
AppExceptionResolver appExceptionResolver = new AppExceptionResolver();
appExceptionResolver.setOrder(1);
exceptionResolvers.add(appExceptionResolver);
}
@Override
public void configureMessageConverters(List<HttpMessageConverter<?>> converters) {
MMHFastjsonHttpMessageConverter messageConverter = new MMHFastjsonHttpMessageConverter();
messageConverter.setSupportedMediaTypes(Lists.newArrayList(MediaType.APPLICATION_JSON_UTF8));
messageConverter.setDefaultCharset(Charset.forName("UTF-8"));
converters.add(messageConverter);
}
@Override
public void configureContentNegotiation(ContentNegotiationConfigurer configurer) {
configurer.favorPathExtension(false);
}
}
@Signature
@RequestMapping(value = {"/V2/sms/vcode/sendSmsVcodeForLoginOrReg.htm","/s/V2/sms/vcode/sendSmsVcodeForLoginOrReg.htm"})
@Signature
public void sendSmsVcodeForLoginOrRegV2() {
responseSuccessJson(response);
}
通过以上4部,再启动项目的时候,拦截器节开始了它的拦截功能,会针对添加了
@Signature
的接口,运行前置拦截功能,验签通过才执行接口本来的业务逻辑。
本段代码的核心是HandlerInterceptorAdapter
这个类,拦截适配器 它提供了4个方法:
