這篇文章主要介紹了JAVA 對接騰訊云直播的實現(xiàn)，文中通過示例代碼介紹的非常詳細(xì)，對大家的學(xué)習(xí)或者工作具有一定的參考學(xué)習(xí)價值，需要的朋友們下面隨著小編來一起學(xué)習(xí)學(xué)習(xí)吧

簽名授權(quán)

public static T TecentDoPostJsonV3(String url,String key,String secretId, TecentPublicParams header, String json, OkHttpClient httpClient, Class clazz) throws Exception {
 // ************* 步驟 1：拼接規(guī)范請求串 *************
  String date = DateUtils.format(new Date(Long.valueOf(header.getX_TC_Timestamp() + "000")),DateUtils.FORMAT_SHORT);

  System.out.println(json);

  JSONObject jsonObject = (JSONObject)JSON.toJSON(header);
  RequestBody requestBody = RequestBody.create(CONTENT_TYPE, json);

     continue;
   }
   builder.addHeader(String.valueOf(entry.getKey()).replaceAll("_","-"),String.valueOf(entry.getValue()));

  try {

   String request = response.body().string();
   T t = JSON.parseObject(request, clazz);
   return t;
  } catch (IOException var8) {
   throw new ApiProcessException(ErrorCode.HTTP_REQUEST_ERROR, var8.getMessage());
  }
}
public static  byte[] hmac256(byte[] key, String msg) throws Exception {
  Mac mac = Mac.getInstance("HmacSHA256");
  SecretKeySpec secretKeySpec = new SecretKeySpec(key, mac.getAlgorithm());
  mac.init(secretKeySpec);
  return mac.doFinal(msg.getBytes(CHARSET));
}

公共參數(shù)實體類

public class TecentPublicParams {
  private String X_TC_Action;
  private String X_TC_Region;
  private String X_TC_Timestamp = Long.toString(System.currentTimeMillis() / 1000);
  private String X_TC_Version;
  private String Authorization;
  private String X_TC_Language = "zh-CN";
  private String X_TC_Token;

  public String getX_TC_Action() {
    return X_TC_Action;
  }

  public void setX_TC_Action(String x_TC_Action) {
    X_TC_Action = x_TC_Action;
  }

  public String getX_TC_Region() {
    return X_TC_Region;
  }

  public void setX_TC_Region(String x_TC_Region) {
    X_TC_Region = x_TC_Region;
  }

  public String getX_TC_Timestamp() {
    return X_TC_Timestamp;
  }

  public void setX_TC_Timestamp(String x_TC_Timestamp) {
    X_TC_Timestamp = x_TC_Timestamp;
  }

  public String getX_TC_Version() {
    return X_TC_Version;
  }

  public void setX_TC_Version(String x_TC_Version) {
    X_TC_Version = x_TC_Version;
  }

  public String getAuthorization() {
    return Authorization;
  }

  public void setAuthorization(String authorization) {
    Authorization = authorization;
  }

  public String getX_TC_Language() {
    return X_TC_Language;
  }

  public void setX_TC_Language(String x_TC_Language) {
    X_TC_Language = x_TC_Language;
  }

  public String getX_TC_Token() {
    return X_TC_Token;
  }

  public void setX_TC_Token(String x_TC_Token) {
    X_TC_Token = x_TC_Token;
  }
}

調(diào)用方法

String tencentLiveApi = "live.tencentcloudapi.com";
String SECRET_KEY = "***"; //此處填寫自己騰訊云key
String SECRET_ID = "***"; //此處填寫自己騰訊云密匙
TecentPublicParams tecentPublicParams = new TecentPublicParams();
tecentPublicParams.setX_TC_Action("DescribeLiveStreamPublishedList"); //對應(yīng)方法名
tecentPublicParams.setX_TC_Version("2018-08-01");
TreeMap keyValues = new TreeMap(); //參數(shù)
keyValues.put("DomainName","***");
keyValues.put("EndTime", DateUtils.format(new Date(),"yyyy-MM-dd'T'HH:mm:ss'Z'"));
keyValues.put("StartTime", DateUtils.format(DateUtils.addDay(new Date(),-30),"yyyy-MM-dd'T'HH:mm:ss'Z'"));
String back ="";
try {
  back = LiveUtils.TecentDoPostJsonV3(tencentLiveApi,SECRET_KEY,SECRET_ID,tecentPublicParams,JSON.toJSONString(keyValues),httpClient,String.class);
} catch (Exception e) {
  e.printStackTrace();
}
