如何在客户端上运行时删除dart中的cookie?
我试图通过使用
将其设置为空字符串来删除它document.cookie = 'cookie_to_be_deleted=""';
如果我在此行之后打印cookie的值,我会得到一个以分号分隔的键值对列表,其中包含两个“cookie_to_be_deleted”实例。一个具有我希望删除的原始值,另一个具有值为空的字符串。
答案 0 :(得分:7)
试试这个:
Date then = new Date.fromEpoch(0, new TimeZone.utc());
document.cookie = 'cookie_to_be_deleted=; expires=' + then.toString() + '; path=/';

void createCookie(String name, String value, int days) {
String expires;
if (days != null) {
Date now = new Date.now();
Date date = new Date.fromEpoch(now.value + days*24*60*60*1000, new TimeZone.local());
expires = '; expires=' + date.toString();
} else {
Date then = new Date.fromEpoch(0, new TimeZone.utc());
expires = '; expires=' + then.toString();
}
document.cookie = name + '=' + value + expires + '; path=/';
}
String readCookie(String name) {
String nameEQ = name + '=';
List<String> ca = document.cookie.split(';');
for (int i = 0; i < ca.length; i++) {
String c = ca[i];
c = c.trim();
if (c.indexOf(nameEQ) == 0) {
return c.substring(nameEQ.length);
}
}
return null;
}
void eraseCookie(String name) {
createCookie(name, '', null);
}
