### Java请求示例

快速接入基础代码请下载相关依赖源码， [点击下载源代码](https://git.polyv.net/help-center/document-center/-/blob/master/third_res/util.zip) ,下载后加入到自己的源码工程中即可。测试用例中的**HttpUtil.java 和 VodSignUtil.java** 都包含在下载文件中。

> 强烈建议您使用[点播Java SDK](https://git.polyv.net/help-center/document-center/-/blob/master/vod/java/README.md)完成API的功能对接，点播Java SDK 对API调用逻辑、异常处理、数据签名、HTTP请求线程池进行了统一封装和优化。

```java
private static final Logger log = LoggerFactory.getLogger(VodVideoManageManagementTest.class);
/**
 * 查询问答题目
 */
@Test
public void testGetQuizResult() throws Exception, NoSuchAlgorithmException {
    //公共参数,填写自己的实际参数
    String secretKey = super.secretKey;
    String userId = super.userId;
    String ptime = String.valueOf(System.currentTimeMillis());
    //业务参数
    String url = "http://api.polyv.net/v2/video/get-video-exam";
    String vid = "1b448be3231ebf0005ec631a7e4247ee_1";

    //调用参数
    Map<String, String> requestMap = new HashMap<>();
    requestMap.put("userid", userId);
    requestMap.put("ptime", ptime);
    requestMap.put("vid", vid);
    requestMap.put("sign", VodSignUtil.getSign(requestMap, secretKey));
    String response = HttpUtil.postFormBody(url, requestMap);
    log.debug("测试查询问答题目,{}", response);
    //do somethings
}
```
