花生壳和神卓互联内网穿透那个好用？

目前企业级主流的穿透技术分别是花生壳和神卓互联，虽然两家公司在稳定性方面表现相当，用户可以根据自己的需求和喜好选择其中之一作为内网穿透服务。无论选择哪一个，都可以享受到高质量、稳定可靠的内网穿透服务。同时还测试了一些网络上其他内网穿透产品，测试下来发现他们基本都一样，都是一些个人网上开源内网穿透项目搭建的。

神卓互联

两个内网穿透都可以拿来开发web应用调试。

分享一个 Java web 应用调试

1. 用户表设计：

CREATE TABLE user (
  id INT PRIMARY KEY AUTO_INCREMENT,
  username VARCHAR(50) NOT NULL,
  password VARCHAR(100) NOT NULL,
  remember_me BOOLEAN DEFAULT false
);

2. 登录页面：

<form id="loginForm" method="post">
    <input type="text" name="username" placeholder="Username" required>
    <input type="password" name="password" placeholder="Password" required>
    <input type="checkbox" name="rememberMe" id="rememberMe" value="true">
    <label for="rememberMe">Remember me</label>
    <button type="submit">Log in</button>
</form>

<script>
    $('#loginForm').submit(function(event) {
        event.preventDefault();
        var formData = {
            'username': $('input[name=username]').val(),
            'password': $('input[name=password]').val(),
            'rememberMe': $('input[name=rememberMe]').is(':checked')
        };
        $.ajax({
            type: 'POST',
            url: '/login',
            data: formData,
            success: function(response) {
                window.location.href = '/';
            },
            error: function(xhr) {
                alert(xhr.responseText);
            }
        });
    });
</script>

3. Spring Security配置：

@Configuration
@EnableWebSecurity
public class SecurityConfig extends WebSecurityConfigurerAdapter {
 
    @Autowired
    private UserDetailsService userDetailsService;
 
    @Autowired
    private RememberMeServices rememberMeServices;
 
    @Override
    protected void configure(HttpSecurity http) throws Exception {
        http
            .authorizeRequests()
                .antMatchers("/", "/home").permitAll()
                .anyRequest().authenticated()
                .and()
            .formLogin()
                .loginPage("/login")
                .defaultSuccessUrl("/")
                .permitAll()
                .and()
            .rememberMe()
                .key("mySecretKey")
                .rememberMeServices(rememberMeServices)
                .and()
            .logout()
                .permitAll();
    }
 
    @Autowired
    public void configureGlobal(AuthenticationManagerBuilder auth) throws Exception {
        auth.userDetailsService(userDetailsService);
    }
 
    @Bean
    public RememberMe

4. 开发记住密码功能：

@Controller
public class LoginController {
 
    @Autowired
    private UserService userService;
 
    @GetMapping("/login")
    public String showLoginPage() {
        return "login";
    }
 
    @PostMapping("/login")
    public ResponseEntity<String> processLogin(@RequestParam String username, @RequestParam String password,
            @RequestParam(required = false) boolean rememberMe, HttpServletResponse response) {
        User user = userService.authenticate(username, password);
        if (user != null) {
            SecurityContextHolder.getContext().setAuthentication(
                    new UsernamePasswordAuthenticationToken(user.getUsername(), user.getPassword()));
            if (rememberMe) {
                userService.setRememberMe(username, password);
                rememberMeServices.loginSuccess(request, response, authentication);
            } else {
                userService.clearRememberMe(username);
            }
            return ResponseEntity.ok("Login success");
        } else {
            return ResponseEntity.status(HttpStatus.UNAUTHORIZED).body("Login failed");
        }
    }
}

@Service
public class UserServiceImpl implements UserService {
 
    @Autowired
    private UserRepository userRepository;
 
    @Override
    public User authenticate(String username, String password) {
        User user = userRepository.findByUsername(username);
        if (user != null && user.getPassword().equals(password)) {
            return user;
        } else {
            return null;
        }
    }
 
    @Override
    public void setRememberMe(String username, String password) {
        User user = userRepository.findByUsername(username);
        if (user != null) {
            user.setRememberMe(true);
            user.setPassword(passwordEncoder.encode(password));
            userRepository.save(user);
        }
    }
 
    @Override
    public void clearRememberMe(String username) {
        User user = userRepository.findByUsername(username);
        if (user != null) {
            user.setRememberMe(false);
            user.setPassword(null);
            userRepository.save(user);
        }
    }
}

5. 注销功能：

<form id="logoutForm" method="post" action="/logout">
    <input type="hidden" name="${_csrf.parameterName}" value="${_csrf.token}">
    <button type="submit">Log out</button>
</form>

完整的代码可以参考以下示例：

6. UserController.java

@Controller
public class UserController {
 
    @GetMapping("/")
    public String showHomePage() {
        return "home";
    }
 
    @GetMapping("/profile")
    public String showProfilePage() {
        return "profile";
    }
}

未完待续！
