API开放平台基于accessToken实现

A企业和B企业要进行合作时，A要开放api接口给B调用，这时候A可以采用基于accessToken的方式实现开放api接口

数据库表设计

B调用方式

B企业调用接口前先获取accessToken

http://localhost:8080/auth/getAccessToken?appId=123456&appSecret=a1b2c3

然后调动真正的业务方法时携带accessToken

http://localhost:8080/openApi/getUser?accessToken=ac18deb132684f6c8cb2c01bd85f86aa

A企业具体实现

A企业设置accessToken过期时间为2小时，并且启动一个job定时刷新

A企业在拦截器里拦截所有的开放api接口，验证accessToken是否存在，是否过期，如果accessTokne存在并且没有过期就可以继续执行业务方法

@Component
public class AccessTokenInterceptor extends BaseApiService implements HandlerInterceptor {
    
    @Autowired
    private BaseRedisService baseRedisService;

    public boolean preHandle(HttpServletRequest httpServletRequest, HttpServletResponse httpServletResponse, Object o)
            throws Exception {
        System.out.println("---------------------开始进入请求地址拦截----------------------------");
        String accessToken = httpServletRequest.getParameter("accessToken");
        // 判断accessToken是否空
        if (StringUtils.isEmpty(accessToken)) {
            // 参数Token accessToken
            resultError(" this is parameter accessToken null ", httpServletResponse);
            return false;
        }
        String appId = (String) baseRedisService.getString(accessToken);
        if (StringUtils.isEmpty(appId)) {
            // accessToken 已经失效!
            resultError(" this is  accessToken Invalid ", httpServletResponse);
            return false;
        }
        // 正常执行业务逻辑...
        return true;

    }

    public void postHandle(HttpServletRequest httpServletRequest, HttpServletResponse httpServletResponse, Object o,
            ModelAndView modelAndView) throws Exception {
        System.out.println("--------------处理请求完成后视图渲染之前的处理操作---------------");
    }

    public void afterCompletion(HttpServletRequest httpServletRequest, HttpServletResponse httpServletResponse,
            Object o, Exception e) throws Exception {
        System.out.println("---------------视图渲染之后的操作-------------------------0");
    }

    // 返回错误提示
    public void resultError(String errorMsg, HttpServletResponse httpServletResponse) throws IOException {
        PrintWriter printWriter = httpServletResponse.getWriter();
        printWriter.write(new JSONObject().toJSONString(setResultError(errorMsg)));
    }

}
