在初始化参数时，加以下代码：

link: {
    // https://ckeditor.com/docs/ckeditor5/latest/features/link.html
    // addTargetToExternalLinks: true,
    decorators: {
        addTargetToExternalLinks: {
            mode: 'automatic',
            callback: url => /^(https?:)?\/\//.test( url ),
            attributes: {
                target: '_blank',
                // rel: 'noopener noreferrer'
            }
        }
    }
},
