Cookie相关

操作Cookie相关内容。

获取Cookie

/**
 * 获取cookie
 *
 * @export
 * @param {string} coockiename
 * @return {*}  {(string | undefined)}
 */
export function getCookieValue(coockiename: string): string | undefined {
  try {
    const name = coockiename + '=';
    const ca = document.cookie.split(';');
    for (let i = 0; i < ca.length; i++) {
      const c = ca[i].trim();
      if (c.indexOf(name) == 0) {
        return c.substring(name.length, c.length);
      }
    }
  } catch (e) {}
  return undefined;
}

设置Cookie

/**
 * 设置cookie
 *
 * @export
 * @param {string} name
 * @param {string} val
 * @param {number} [expTime=365]
 */
export function setCookieValue(name: string, val: string, expTime = 365) {
  // 默认cookie有效期365天, 严格设置GTM格式
  const exp = new Date(Date.now() + expTime * 864e5);
  document.cookie = `${name}=${encodeURIComponent(
    val
  )};expires=${exp.toUTCString()}; path=/; domain=${getCookieDomain()};`;
}

获取主域名

/**
 * 获取主域名，如果域名是ip，直接返回 eg:www.baidu.com => .baidu.com
 * @export
 * @param {string} [hostName]
 * @return {*}  {string}
 */
export function getCookieDomain(hostName?: string): string {
  const initialHost: string = hostName || location.hostname;
  let host: string = initialHost;

  const ip =
    /^(\\d{1,2}|1\\d\\d|2[0-4]\\d|25[0-5])\\.(\\d{1,2}|1\\d\\d|2[0-4]\\d|25[0-5])\\.(\\d{1,2}|1\\d\\d|2[0-4]\\d|25[0-5])\\.(\\d{1,2}|1\\d\\d|2[0-4]\\d|25[0-5])$/;

  if (ip.test(initialHost) === true || initialHost === 'localhost') return initialHost;

  const regex = /([^]*).*/;
  const match: RegExpMatchArray | null = initialHost.match(regex);

  if (match !== undefined && match !== null) host = match[1];

  if (host !== undefined && host !== null) {
    const strAry: string[] = host.split('.');
    if (strAry.length > 2) {
      host = strAry.slice(1).join('.');
    }
  }
  return `.${host}`;
