【Code】Cookie操作封装

const getDomain = () => {
    const host = window.location.host
    if(host==='localhost:8080') {
        // 植入cookie时不可设置domain
        return ''
    }
    const arr = host.split('.')
    if (arr.length > 2) {
        const len = arr.length
        return `${arr[len - 2]}.${arr[len - 1]}`
    }
    return host
}
