cookie方法封装

方法封装：

/**
 * 获取cookie
 */
export function getCookie(sKey: string): string {
  if (!sKey) { return null; }
  return decodeURIComponent(document.cookie.replace(new RegExp("(?:(?:^|.*;)\\s*" + encodeURIComponent(sKey).replace(/[\-\.\+\*]/g, "\\$&") + "\\s*\\=\\s*([^;]*).*$)|^.*$"), "$1")) || null;
}

/**
 * 设置cookie
 */
export function setCookie(sKey: string, sValue: string, vEnd: any = 0, sPath: string = '/', sDomain: string = '', bSecure: boolean = false): boolean {
  if (!sKey || /^(?:expires|max\-age|path|domain|secure)$/i.test(sKey)) { return false; }
  var sExpires = "";
  if (vEnd) {
    switch (vEnd.constructor) {
      case Number:
        sExpires = vEnd === Infinity ? "; expires=Fri, 31 Dec 9999 23:59:59 GMT" : "; max-age=" + vEnd;
        /*
        Note: Despite officially defined in RFC 6265, the use of `max-age` is not compatible with any
        version of Internet Explorer, Edge and some mobile browsers. Therefore passing a number to
        the end parameter might not work as expected. A possible solution might be to convert the the
        relative time to an absolute time. For instance, replacing the previous line with:
        */
        /*
        sExpires = vEnd === Infinity ? "; expires=Fri, 31 Dec 9999 23:59:59 GMT" : "; expires=" + (new Date(vEnd * 1e3 + Date.now())).toUTCString();
        */
        break;
      case String:
        sExpires = "; expires=" + vEnd;
        break;
      case Date:
        sExpires = "; expires=" + vEnd.toUTCString();
        break;
    }
  }
  document.cookie = encodeURIComponent(sKey) + "=" + encodeURIComponent(sValue) + sExpires + (sDomain ? "; domain=" + sDomain : "") + (sPath ? "; path=" + sPath : "") + (bSecure ? "; secure" : "");
  return true;
}

/**
 * 删除cookie
 */
export function removeCookie(sKey: string, sPath: string, sDomain: string): boolean {
  if (!hasCookie(sKey)) { return false; }
  document.cookie = encodeURIComponent(sKey) + "=; expires=Thu, 01 Jan 1970 00:00:00 GMT" + (sDomain ? "; domain=" + sDomain : "") + (sPath ? "; path=" + sPath : "");
  return true;
}

/**
 * 检查cookie
 */
export function hasCookie(sKey: string): boolean {
  if (!sKey || /^(?:expires|max\-age|path|domain|secure)$/i.test(sKey)) { return false; }
  return (new RegExp("(?:^|;\\s*)" + encodeURIComponent(sKey).replace(/[\-\.\+\*]/g, "\\$&") + "\\s*\\=")).test(document.cookie);
}

使用方法：

cookie.setCookie('gymToken','66666666', new Date(86400000 + Date.now()))//添加
cookie.removeCookie('gymToken','/','') //删除
console.error('123123123',cookie.getCookie('gymToken')) //取值
console.error('444444',cookie.hasCookie('gymToken')) //判断
