云点播 播放器签名示例

一、Java 签名示例

使用 java-jwt 库计算签名。

import java.util.*;import com.auth0.jwt.algorithms.Algorithm;import com.auth0.jwt.exceptions.JWTCreationException;import com.auth0.jwt.JWT;class Main { public static void main(String[] args) { Integer AppId = 1255566655; // 用户 appid String FileId = "4564972818519602447"; // 目标 FileId String AudioVideoType = "RawAdaptive"; // 播放的音视频类型 Integer RawAdaptiveDefinition = 10; // 允许输出的未加密的自适应码流模板 ID Integer ImageSpriteDefinition = 10; // 做进度条预览的雪碧图模板 ID Integer CurrentTime = 1589448067; Integer PsignExpire = 1589548067; // 可任意设置过期时间 String UrlTimeExpire = "5ebe9423‬"; // 可任意设置过期时间 String PlayKey = "TxtyhLlgo7J3iOADIron"; HashMap<String, Object> urlAccessInfo = new HashMap<String, Object>(); urlAccessInfo.put("t", UrlTimeExpire); HashMap<String, Object> contentInfo = new HashMap<String, Object>(); contentInfo.put("audioVideoType", AudioVideoType); contentInfo.put("rawAdaptiveDefinition", RawAdaptiveDefinition); contentInfo.put("imageSpriteDefinition", ImageSpriteDefinition); try { Algorithm algorithm = Algorithm.HMAC256(PlayKey); String token = JWT.create().withClaim("appId", AppId).withClaim("fileId", FileId) .withClaim("contentInfo", contentInfo) .withClaim("currentTimeStamp", CurrentTime).withClaim("expireTimeStamp", PsignExpire) .withClaim("urlAccessInfo", urlAccessInfo).sign(algorithm); System.out.println("token:" + token); } catch (JWTCreationException exception) { // Invalid Signing configuration / Couldn't convert Claims. } }}

二、Go 签名示例

使用 jwt-go 库计算签名，请使用命令go get github.com/dgrijalva/jwt-go进行安装。

package mainimport ( "fmt" "time" "strconv" "github.com/dgrijalva/jwt-go")func main() { appId := 1255566655 // 用户 appid fileId := "4564972818519602447" // 目标 FileId audioVideoType := "RawAdaptive" // 播放的音视频类型 rawAdaptiveDefinition := 10 // 允许输出的未加密的自适应码流模板 ID imageSpriteDefinition := 10 // 做进度条预览的雪碧图模板 ID currentTime := time.Now().Unix() psignExpire := currentTime + 3600 // 可任意设置过期时间，示例1h urlTimeExpire := strconv.FormatInt(psignExpire, 16) // 可任意设置过期时间，16进制字符串形式，示例1h playKey := []byte("TxtyhLlgo7J3iOADIron") // Create a new token object, specifying signing method and the claims // you would like it to contain. token := jwt.NewWithClaims(jwt.SigningMethodHS256, jwt.MapClaims{ "appId": appId, "fileId": fileId, "contentInfo": { "audioVideoType": audioVideoType, "rawAdaptiveDefinition": rawAdaptiveDefinition, "imageSpriteDefinition": imageSpriteDefinition, }, "currentTimeStamp": currentTime, "expireTimeStamp": psignExpire, "urlAccessInfo": map[string]string{ "t": urlTimeExpire, }, }) // Sign and get the complete encoded token as a string using the secret tokenString, err := token.SignedString(playKey) fmt.Println(tokenString, err)}

三、C# 签名示例

使用 jose-jwt 计算签名，请使用 NuGet 命令Install-Package jose-jwt进行安装。

using System;using System.Text;using System.Collections.Generic;using Jose;public class Program{ public static void Main() { var appId = 1255566655; // 用户 appid var fileId = "4564972818519602447"; // 目标 FileId var audioVideoType = "RawAdaptive"; // 播放的音视频类型 var rawAdaptiveDefinition = 10; // 允许输出的未加密的自适应码流模板 ID var imageSpriteDefinition = 10; // 做进度条预览的雪碧图模板 ID var currentTime = DateTimeOffset.UtcNow.ToUnixTimeSeconds(); var psignExpire = currentTime + 3600; // 可任意设置过期时间，示例1h var urlTimeExpire = psignExpire.ToString("X4"); // 可任意设置过期时间，16进制形式，示例1h var playKey = "TxtyhLlgo7J3iOADIron"; var playKeyBytes = Encoding.ASCII.GetBytes(playKey); var payload = new Dictionary<string, object>() { {"appId", appId}, {"fileId", fileId}, {"contentInfo", new Dictionary<string, object>() { {"audioVideoType", audioVideoType}, {"rawAdaptiveDefinition", rawAdaptiveDefinition}, {"imageSpriteDefinition", imageSpriteDefinition} } }, {"currentTimeStamp", currentTime}, {"expireTimeStamp", psignExpire}, {"urlAccessInfo", new Dictionary<string, object>() { {"t", urlTimeExpire} } } }; string token = Jose.JWT.Encode(payload, playKeyBytes, JwsAlgorithm.HS256); Console.WriteLine(token); }}

四、PHP 签名示例

使用 php-jwt 计算签名，请使用命令composer require firebase/php-jwt进行安装。

<?phprequire 'vendor/autoload.php';use \\Firebase\\JWT\\JWT;$appId = 1255566655; // 用户 appid$fileId = "4564972818519602447"; // 目标 FileId$audioVideoType = "RawAdaptive"; // 播放的音视频类型$rawAdaptiveDefinition = 10; // 允许输出的未加密的自适应码流模板 ID$imageSpriteDefinition = 10; // 进度条预览的雪碧图模板 ID$currentTime = time();$psignExpire = $currentTime + 3600; // 可任意设置过期时间，示例1h$urlTimeExpire = dechex($psignExpire); // 可任意设置过期时间，16进制字符串形式，示例1h$playKey = "TxtyhLlgo7J3iOADIron";$payload = array( "appId" => $appId, "fileId" => $fileId, "contentInfo" => array( "audioVideoType"=> $audioVideoType, "rawAdaptiveDefinition"=> $rawAdaptiveDefinition, "imageSpriteDefinition"=> $imageSpriteDefinition ), "currentTimeStamp" => $currentTime, "expireTimeStamp" => $psignExpire, "urlAccessInfo" => array( "t" => $urlTimeExpire ));$jwt = JWT::encode($payload, $playKey, 'HS256');print_r($jwt);?>

五、Node.js 签名示例

使用 jsonwebtoken 计算签名，请使用命令npm install jsonwebtoken进行安装。
