FederationToken鉴权不可用

错误提示:     Error: Error Domain=please set generateToken first ! Code=0 "The operation couldn’t be completed. (please set generateToken first ! error 0.)"


我的鉴权代码

[ossService setAuthenticationType:FEDERATION_TOKEN];
    OSSFederationToken *federation = [[OSSFederationToken alloc] initWithAk:accessKeyId sk:accessKeySecret tempToken:securityToken expiration:expiration];
    [ossService setFederationTokenGetter:^OSSFederationToken *{
        return federation;
    }];

请提出详细日志

-------------------------

token过期了，重新生成吧
