public static T TecentDoPostJsonV3(String url,String key,String secretId, TecentPublicParams header, String json, OkHttpClient httpClient, Class clazz) throws Exception {
// ************* 步骤 1:拼接规范请求串 *************
String date = DateUtils.format(new 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 ="POST\n" +
"/\n" +

"host:"+url+"\n" +

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);

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)).toLowerCase();
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 = new 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.newCall((builder).url("https://"+url).post(requestBody).build()).execute();
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));
