自定义注解@EnableHikHttpRequest、@HikHttp、@HikHttpRequest 实现对海康平台接口访问

完整代码

• 对接海康开放平台通常，先引入SDK，然后更具API文档去写需要的实现类接口，接口里面拼接各种参数，然后调用SDK返回太烦了，代码不够简洁，受到Feign启发，将对海康平台接口访问封装成注解的形式

@HikHttp
public interface HikPlatformApiService {

    @HikHttpRequest(value = HikApiConstant.personList, method = HttpMethod.POST)
    public HikVo createNetEaseAcc(Map params);

}

-传统的调用方式

`

/**
 * 调用POST接口，返回图片
 * 接口实际url：https://ip:port/artemis/api/visitor/v1/record/pictures
 * @return
 */
public static String callPostImgs() throws Exception {
    ArtemisConfig config = new ArtemisConfig();
    config.setHost("127.0.0.1"); // 代理API网关nginx服务器ip端口
    config.setAppKey("20469790");  // 秘钥appkey
    config.setAppSecret("lofnD6DbnBllHmk5YOyx");// 秘钥appSecret
    final String getSecurityApi = "/artemis" + "/api/visitor/v1/record/pictures"; // 接口路径
    Map<String, String> path = new HashMap<String, String>(2) {
        {
            put("https://", getSecurityApi);
        }
    };
    Map<String, String> head = new HashMap<String, String>(2) {  //get请求的head参数
        {
            put("headpost", "sky-test");
        }
    };
    Map<String, String> query = new HashMap<String, String>(2) {  //get请求的head参数
        {
            put("domainId", "0");
        }
    };
    JSONObject jsonBody = new JSONObject();
    jsonBody.put("svrIndexCode", "9ff58bc2-65a5-464b-b28c-daea67ba9569");

    String body = jsonBody.toJSONString();
    //参数根据接口实际情况设置
    HttpResponse result = ArtemisHttpUtil.doPostStringImgArtemis(config, path, body, query, null,"application/json",head);
    try {
        HttpResponse resp = result;
        if (302==resp.getStatusLine().getStatusCode()) {
            /*
            获取图片数据保存到本地
            注：1.对于有时效的图片，必须尽快保存到本地
               2.若无时效，则可以直接保存location，后续自行访问获取
             */
            Header header=  resp.getFirstHeader("location");
            String  newUrl = header.getValue();
            HttpGet httpget = new HttpGet(newUrl);
            HttpClient httpClient = wrapClient(httpget.getURI().getScheme()+"://"+httpget.getURI().getHost());
            HttpResponse execute = httpClient.execute(httpget);
            HttpEntity entity = execute.getEntity();
            InputStream in = entity.getContent();
            Tools.savePicToDisk(in, "d:/", "test311.jpg");
        }else{
            System.out.println("下载出错");
        }

    } catch (Exception e) {
        e.printStackTrace();
    }

    return getSecurityApi;
}

public static void main(String[] args) throws Exception {
    String result = callPostApiGetOrgList();
    System.out.println(result);
    String VechicleDataResult = callPostApiGetRegions();
    System.out.println(VechicleDataResult);
}

}

• 使用注解后，简洁明了

• 使用
  先在启动类上加上@EnableHikHttpRequest("com.coder.gctool.test")注解，和对应要扫描的包
  然后在该包下写接口
  

接口上添加@HikHttp注解，方法上添加 @HikHttpRequest注解就完成了
