JAVA 对接腾讯云直播的实现

签名授权

public static T TecentDoPostJsonV3(String url,String key,String secretId, TecentPublicParams header, String json, OkHttpClient httpClient, Class clazz) thros Exception {
 //  步骤 1拼接规范请求串 
  String date = DateUtils.format(ne Date(Long.valueOf(header.getX_TC_Timestamp() + "000")),DateUtils.FORMAT_SHORT);
  String service = url.substring(0,url.indexOf(".")); //截取服务类型 云直播是live
  System.out.println(json);
  String canonicalRequest ="POSTn" +
  "/n" +
  "n" +
  "content-type:application/json; charset=utf-8n" +
  "host:"+url+"n" +
  "n" +
  "content-type;hostn" +
  sha256Hex(json);
  System.out.println(canonicalRequest);
  //  步骤 2拼接待签名字符串 
  String credentialScope = date+ "/" + service + "/" + "tc3_request";
  String hashedCanonicalRequest = sha256Hex(canonicalRequest);
  String algorithm = "TC3-HMAC-SHA256";
  String stringToSign = algorithm + "n" + header.getX_TC_Timestamp() + "n" + credentialScope + "n" + hashedCanonicalRequest;
  System.out.println(stringToSign);
  //  步骤 3计算签名 
  byte[] secretDate = hmac256(("TC3" + key).getBytes(CHARSET), date);
  byte[] secretService = hmac256(secretDate, service);
  byte[] secretSigning = hmac256(secretService, "tc3_request");
  String signature = DatatypeConverter.printHexBinary(hmac256(secretSigning, stringToSign)).toLoerCase();
  System.out.println(signature);
  //  步骤 4拼接 Authorization 
  String authorization = algorithm + " " + "Credential=" + secretId + "/" + credentialScope + ", "
  + "SignedHeaders=" + "content-type;host" + ", " + "Signature=" + signature;
  System.out.println(authorization);
  header.setAuthorization(authorization);
  JSonObject jsonObject = (JSONObject)JSON.toJSON(header);
  RequestBody requestBody = RequestBody.create(CONTENT_TYPE, json);
  Request.Builder builder = ne Request.Builder();

  for (Map.Entry entry:jsonObject.entrySet()) {
   if(entry.getValue()==null){
  continue;
   }
   builder.addHeader(String.valueOf(entry.getKey()).replaceAll("_","-"),String.valueOf(entry.getValue()));
  }
  // 用okhttp3 拼接发送请求
  try {
   Response response = httpClient.neCall((builder).url("https://"+url).post(requestBody).build()).execute();

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

公共参数实体类

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;
  }
}

调用方法

String tencentLiveApi = "live.tencentcloudapi.";
String SECRET_KEY = ""; //此处填写自己腾讯云key
String SECRET_ID = ""; //此处填写自己腾讯云密匙
TecentPublicParams tecentPublicParams = ne TecentPublicParams();
tecentPublicParams.setX_TC_Action("DescribeLiveStreamPublishedList"); //对应方法名
tecentPublicParams.setX_TC_Version("2018-08-01");
TreeMap keyValues = ne TreeMap(); //参数
keyValues.put("DomainName","");
keyValues.put("EndTime", DateUtils.format(ne Date(),"yyyy-MM-dd'T'HH:mm:ss'Z'"));
keyValues.put("StartTime", DateUtils.format(DateUtils.addDay(ne 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();
}
