Blackbird有一个简单的方法将返回值发送到控制台: Javascript代码 复制代码 代码如下: log.debug( 'this is a debug message' ); log.info( 'this is an info message' ); log.warn( 'this is a warning message' ); log.error( 'this is an error message' ); log.debug( 'this is a debug message' ); log.info( 'this is an info message' ); log.warn( 'this is a warning message' ); log.error( 'this is an error message' );
