Expected function call and instead saw an expressiont

Question

 getcookiesInServer(req) {
    const serviceCookie = {};
    req && req.headers.cookie && req.headers.cookie.split(';').forEach((val) => {
      const parts = val.split('=');
      serviceCookie[parts[0].trim()] = (parts[1] || '').trim();
    });
    return serviceCookie;
  },
  // 获取客户端cookie
  getcookiesInClient(key) {
    return Cookie.get(key) ? Cookie.get(key) : '';
  },

报这个错误 Expected an assignment or function call and instead saw an expression
应该怎么改啊，第3行的错误？

Answer 1

if (req && req.headers.cookie) {
    req.headers.cookie.split(';').forEach((val) => {
      const parts = val.split('=');
      serviceCookie[parts[0].trim()] = (parts[1] || '').trim();
    });
}
