统一身份认证系统与App集成的技术实现

// 使用OAuth2.0获取Access Token

String accessToken = getAccessToken("client_id", "client_secret", "grant_type=client_credentials");

// 使用JWT验证用户身份

String jwtToken = generateJWT(accessToken);

// 在请求头中携带JWT

HttpHeaders headers = new HttpHeaders();

headers.set("Authorization", "Bearer " + jwtToken);

HttpEntity entity = new HttpEntity<>("body", headers);

ResponseEntity response = restTemplate.exchange("https://api.example.com/user", HttpMethod.GET, entity, String.class);
