以下是一个简单的授权码功能的实现示例,使用Java Spring Boot框架:

  1. 定义授权码类:
public class AuthorizationCode {
    private String code;
    private String clientId;
    private LocalDateTime expiresAt;

    // 构造函数、getter和setter方法
}
  1. 定义授权码存储类:
@Component
public class AuthorizationCodeStore {
    private Map<String, AuthorizationCode> codeMap = new HashMap<>();

    public void save(AuthorizationCode code) {
        codeMap.put(code.getCode(), code);
    }

    public AuthorizationCode get(String code) {
        return codeMap.get(code);
    }

    public void delete(String code) {
        codeMap.remove(code);
    }
}
  1. 定义授权码生成器类:
@Component
public class AuthorizationCodeGenerator {
    private SecureRandom secureRandom = new SecureRandom();

    public AuthorizationCode generate(String clientId) {
        String code = new BigInteger(130, secureRandom).toString(32);
        LocalDateTime expiresAt = LocalDateTime.now().plusMinutes(10);

        AuthorizationCode authCode = new AuthorizationCode();
        authCode.setCode(code);
        authCode.setClientId(clientId);
        authCode.setExpiresAt(expiresAt);

        return authCode;
    }
}
  1. 定义授权码控制器类:
@RestController
@RequestMapping("/authorize")
public class AuthorizationCodeController {
    @Autowired
    private AuthorizationCodeGenerator codeGenerator;

    @Autowired
    private AuthorizationCodeStore codeStore;

    @PostMapping("/code")
    public ResponseEntity<String> getCode(@RequestParam String clientId) {
        AuthorizationCode code = codeGenerator.generate(clientId);
        codeStore.save(code);
        return ResponseEntity.ok(code.getCode());
    }

    @GetMapping("/validate")
    public ResponseEntity<Void> validateCode(@RequestParam String code) {
        AuthorizationCode authCode = codeStore.get(code);
        if (authCode == null || authCode.getExpiresAt().isBefore(LocalDateTime.now())) {
            return ResponseEntity.status(HttpStatus.UNAUTHORIZED).build();
        } else {
            codeStore.delete(code);
            return ResponseEntity.ok().build();
        }
    }
}
  1. 在应用程序启动类上添加@EnableWebMvc注解:
@SpringBootApplication
@EnableWebMvc
public class MyApp {
    public static void main(String[] args) {
        SpringApplication.run(MyApp.class, args);
    }
}

这个授权码功能的实现示例使用了内存存储,实际应用中可以使用数据库或缓存等持久化存储方案。此外,还需要考虑安全性和性能等方面的问题。
