segmentfault 强制跳转 https的代码片段，随手记录下：
(function(currentUrl) {
if (typeof URL != 'undefined') {
// 测试环境
if ('https://segmentfault.com' === '//localhost:3000') return
var baseUrl = new URL('https://segmentfault.com');
if (baseUrl.protocol != currentUrl.protocol || baseUrl.host != currentUrl.host) {
window.location.href = baseUrl.protocol + '//' + baseUrl.host + currentUrl.pathname + currentUrl.search + currentUrl.hash;
}
}
})(window.location);
(function(currentUrl) {
if (typeof URL != 'undefined') {
var baseUrl = new URL('https://segmentfault.com');
if (baseUrl.protocol != currentUrl.protocol ||
baseUrl.host != currentUrl.host) {
window.location.href = baseUrl.protocol + '//' + baseUrl.host +
currentUrl.pathname + currentUrl.search + currentUrl.hash;
}
}
})(window.location);
;(function(currentUrl) {
if (typeof URL != 'undefined') {
var baseUrl = new URL('https://a.com');
if (baseUrl.host === currentUrl.host && baseUrl.protocol != currentUrl.protocol) {
window.location.href = baseUrl.protocol + '//' + baseUrl.host +
currentUrl.pathname + currentUrl.search + currentUrl.hash;
}
}
})(window.location);
