### 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 LiveSignUtil.java** 都包含在下载文件中。

> 强烈建议您使用[直播Java SDK](https://git.polyv.net/help-center/document-center/-/blob/master/live/java/README.md)完成API的功能对接，直播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
/**
 * 修改页脚设置
 * @throws IOException
 * @throws NoSuchAlgorithmException
 */
@Test
public void updateGlobalFooterSettingTest() throws IOException, NoSuchAlgorithmException {
    //公共参数,填写自己的实际参数
    String appId = super.appId;
    String appSecret = super.appSecret;
    String timestamp = String.valueOf(System.currentTimeMillis());
    
    //业务参数
    String url = "http://api.polyv.net/live/v4/user/global-setting/footer/update";
    String showFooterEnabled = "Y";
    String footerText = "保利威提供技术支持";
    String footTextLinkProtocol = "https://";
    String footTextLinkUrl = "www.polyv.net";
    
    //http 调用逻辑
    Map<String, String> requestMap = new HashMap<>();
    requestMap.put("appId", appId);
    requestMap.put("timestamp", timestamp);
    requestMap.put("sign", LiveSignUtil.getSign(requestMap, appSecret));
    
    Map<String, Object> jsonMap = new HashMap<>();
    jsonMap.put("showFooterEnabled", showFooterEnabled);
    jsonMap.put("footerText", footerText);
    jsonMap.put("footTextLinkProtocol", footTextLinkProtocol);
    jsonMap.put("footTextLinkUrl", footTextLinkUrl);
    
    url = HttpUtil.appendUrl(url, requestMap);
    String response = HttpUtil.postJsonBody(url, JSON.toJSONString(jsonMap), null);
    
    log.info("测试修改页脚设置成功：{}", response);
    //do somethings
    
}
```
