Token生成示例

业务接入实时音视频互动服务需要进行Token身份验证。你需要在业务服务器自行生成token，本文介绍如何生成鉴权所需的Token，并提供相关的代码参考。

Golang

• 产生token

	appid:=int32(12345)
	uid:="1234444"
	expiresecs:=int32(46)
	tk:=sctoken.NewSCToken(appid,uid,expiresecs)
	// 设置业务参数
	tk.SetParameter("pkey1","pval1")
	tk.SetParameter("pkey2","pval2")
	// 设置业务权限
	tk.SetPrivilege("pri1",300)
	tk.SetPrivilege("pri2",400)
	// 生成token 串
	token:=tk.BuildToken("appkey1234")

• 验证token

	// 解析token串，生成SCToken对象
	tk,err:=sctoken.ParseToken(token,"appkey1234")
	if err!=nil {
		// print err
	} else {
		   if tk.IsValid(){
			    // token 有效
				// do something
				
			} else {
				// token 已过期
			}
	}

Java

• 产生token

private static void genToken()
    throws UnsupportedEncodingException {

    /*
     * Initialize tokenBuilder, passing your appKey which can be found on developer center
     */
    SCTokenBuilder builder = new SCTokenBuilder( new SCTokenAppSecretProvider() {

        @Override
        public String getAppsecret( int appKey ) {
            // app secret
            return "1234";
        }
    } );
    /*
     * Parameter:
     *
     * version: token Version, integer
     *
     * appid: appKey, integer
     *
     * uid, business definition, string
     *
     * validTime, in seconds, value less then 90 will be set to TOKEN_MIN_VALID_TIME(90s)
     *
     */
    SCTokenPropertyProvider provider = new SCTokenPropertyProvider(2, 1234, "2483549835", 4*60*60);
    // Optional Extend parameters，defined by your app
    provider.getParameterProperties()
            //
            .addTokenExtendProperty("param1","content")
            //
            .addTokenExtendProperty("param2",2);

    // Optional privilege properties，defined by your app
    provider.getPrivilegeProperties()
            //
    .addTokenExtendProperty("privilege1",12345566l)
            //
    .addTokenExtendProperty("privilege2",12345566l);

    //Generate token according to above attribute configuration
    byte[] token = builder.buildBinanyToken( provider );

    // In order to facilitate network transmission,
    // BASE 64 encoding and url_safe mode are used
    Base64 coder = new Base64( 76, new byte[] {}, true );

    // The byte array is converted to a string to print
    String tokenStr = coder.encodeAsString( token );
    System.out.println( "gen token:"+ tokenStr );
}

• 验证token

private static void validToken(String tokenStr) throws UnsupportedEncodingException {
    /*
     * Initialize tokenBuilder, passing your appKey which can be found on develop center
     */
    SCTokenBuilder builder = new SCTokenBuilder( new SCTokenAppSecretProvider() {

        @Override
        public String getAppsecret( int appKey ) {
            // app secret
            return "1234";
        }
    } );
    Base64 coder = new Base64( 76, new byte[] {}, true );

    // parse token，make sure your token is url-safed, mean that '+' and '/' MUST NOT be found in your token
    if (!tokenStr.equals(URLDecoder.decode(tokenStr, "UTF-8"))) {
        throw new SCTokenException("token isn't url-safed");
    }
    byte[] token = coder.decode(tokenStr.getBytes( "UTF-8" ) );

    SCToken scToken = builder.validateTokenBytes( token );
    System.out.println( "decode token: " + scToken.toString());
}

Python

• 产生token

    app_id = 1296325
    app_secret = bytearray(b'abcdefg')
    uid = "987654321"
    valid_time = 100
    build_timestamp = int(time.time() * 1000)
    // 设置业务参数
    parameter = {"pkey1": "pval1", "pkey2": "pval2"}
    // 设置业务权限
    privileges = {"pri1": 300, "pri2": 400}
    // 生成token 串
    token_str = SCToken().gen(app_id, app_secret, uid, parameter, privileges, build_timestamp, valid_time)

• 验证token

    // 解析token串，生成SCToken对象
    app_secret = bytearray(b'abcdefg')
    token_str = "_2dllwAAAHMAADA5AAk5ODc2NTQzMjEAAgAFcGtleTIABXB2YWwyAAVwa2V5MQAFcHZhbDEAAgAEcHJpMQAAAAAAAAEsAARwcmkyAAAAAAAAAZAAAAFsuAVsTAAA6mDjTWxNCdjou_5GSCFCWLtGAgn9Ww"
    
    yt, err = SCToken().parse(token_str, app_secret)
    
    if err != None:
        // print "token 解析失败"
    else:
        if yt.validate():
            // print "token 有效"
            // do something
        else:
            //print "token 过期"
