问题汇总
1、钉钉免登时,要通过dingtalk.js获取一个只能使用一次的code,用次code在服务端获取用户userid;若需要实现自动登录,就不能用传统的用户名密码登录。
2、登录过程中需要从后端获取 accesstoken、jsticket、用户userid,用userid获取userinfo,当accesstoken和jsticket都过期时(7200秒),四个参数皆需要通过网络获取,耗时较长。
3、需要使用spring security保护RESTApi,防止匿名访问。
4、spring security默认表单登录模式,用ajax 增加复杂度。
解决方案
解决思路:
1、前端获取到code时,用corpid作为username,code作为password,重写userDetail,用code能获取到userid时,表明code有效,并用词userid创建新用户,corpid作为密码,添加User权限并返回;
2、accesstoken和jsticket使用独立的程序定时获取,登录时只从数据库取出使用,不从网络获取以减少时间;前端加入loading动画以提升用户体验;开启remeber-me功能,减少登录。
3、配置springSecurity即可,同时将登录事件放置与dd.ready中,防止在钉钉之外的浏览器打开访问。
4、创建form,并使用jQuery填充用户名及密码,使用jQuery模拟click登录。安全性方面,由于corpid公开无妨,code使用次数仅有1此且5分钟有效期,目前暂未使用加密传递;
解决步骤
1、引入springsecurity依赖
compile('org.springframework.boot:spring-boot-starter-security')
2、配置websecurityConfigure
@Configuration
@EnableWebSecurity
public class WebSecurityConfig extends WebSecurityConfigurerAdapter {
private final String KEY="TECHASER";
//注入userBean
@Bean
UserDetailsService customUserService(){
return new DingtalkUserService();
}
//重写登录验证
@Override
protected void configure(AuthenticationManagerBuilder auth)throws Exception{
auth.userDetailsService(customUserService());
}
@Override
protected void configure(HttpSecurity http) throws Exception {
http
.authorizeRequests()
.antMatchers(
HttpMethod.GET,
"/",
"/*.html",
"/favicon.ico",
"/**/*.html",
"/**/*.css",
"/**/*.js",
"/**/*.map",
"/**/*.png",
"/**/*.jpg"
).permitAll()
.anyRequest().authenticated()
.and()
.formLogin()
.loginPage("/login").defaultSuccessUrl("/app").failureUrl("/login/failed").permitAll()
.and().logout().logoutUrl("/logout").logoutSuccessUrl("/login").permitAll()
.and().exceptionHandling().accessDeniedPage("/403")
.and().csrf().disable()
.rememberMe().rememberMeParameter("rememberMe").tokenValiditySeconds(5000).key(KEY);
http.headers().cacheControl();
}
}
登录验证方法:重写 loadUserByUsername即可
@Service
public class DingtalkUserService implements UserDetailsService {
@Autowired
private AuthService authService;
/**
* 使用前台传来的 免登code,从后端获取userId,从error_code=0判断code是否有效,corpId作为密码,并添加ROLE_USER权限
* corpId 前面添加 {noop} ,不使用密码加密
* @param username
* @return
* @throws UsernameNotFoundException
*/
@Override
public UserDetails loadUserByUsername(String username) throws UsernameNotFoundException {
String code=username;
String password="{noop}"+ Company.CORP_ID;
UserResponse userResponse= null;
try {
userResponse = AuthHelper.getUserCode(authService.autoGetAccessToken(),code);
} catch (IOException e) {
e.printStackTrace();
}
System.out.println("errorCode:"+userResponse.getErrcode());
if(userResponse.getErrcode().equals("0")){
List<GrantedAuthority> authorities=new ArrayList<GrantedAuthority>();
authorities.add(new SimpleGrantedAuthority("ROLE_USER"));
System.out.println("password is "+password);
return new User(userResponse.getUserid(),password,authorities);
}else {
return new User("user","{noop}not",new ArrayList<>());
}
}
}

需要通过网络获取的参数诸如accessToken jsTicket Userid等,可参考 http://open.dingtalk.com/
后续需要解决的问题:
1、登录速度需要进一步优化
2、remember-me开启后,需要在页面内提供可供退出登录的连接
3、加密传出数据,启用https
4、可以看到 crsf处于disable状态,需开启
绕过的问题
使用 ajax方式登录时,可以从控制台看出已经登录,并返回了需要打开的文档,但未能跳转页面,不明原因。
2018年8月10日补充更新:
解决了登录缓慢的问题
原先登录速度方面,由于使用了spring security,当webApp中请求过多时,造成认证授权的内容过多,容易发生阻塞:

在请求静态资源时,也会做验证,虽然WebSecurityConfigure中配置忽略:
@Override
public void configure(WebSecurity web) throws Exception {
web
.ignoring()
.antMatchers("/",
"/img/*",
"/*.html",
"/favicon.ico",
"/**/*.html",
"/**/*.css",
"/**/*.js",
"/**/*.map",
"/**/*.png",
"/**/*.jpg",
"/**/*.eot",
"/**/*.ttf",
"/**/*.woff",
"/**/*.woff2",
"/**/*.svg",
"/pages/*",
"/test4"
);
}
总是在某些请求是卡住五六秒,导致从登陆页面跳转至应用首页时发生白屏现象。
解决办法是,尽量减少请求的次数:
1、合并css、js文件
2、开源框架使用cdn 国内推荐使用:https://www.bootcdn.cn
3、页面中的ajax请求放到页面底部 window.onload函数中,待页面框架加载并渲染完成后开始执行。
此时页面访问速度明细提升,从最初的5~10秒到现在1秒内加载完成。
