在服务器上删除Google Analytics（分析）cookie

Question

当我们指定用户不希望启用它们时，我们一直在尝试删除GTM创建的cookie。

我们加载GTM是标头的第一件事，然后是JS cookies库，最后是我们以下代码。

// Loaded page
window.dataLayer = window.dataLayer || [];
function gtag(){
    dataLayer.push(arguments);
}
gtag('js', new Date());
gtag('config', 'XX-XXXXXXXX-X');

if (cookiesEnabled) { // a variable that shows if they are enabled
  // Cookies accepted
  window['ga-disable-XX-XXXXXXXX-X'] = false
} else {
  window['ga-disable-XX-XXXXXXXX-X'] = true
}

// Function to set the cookies
function setCookies (accepted) {
if (!accepted) {
  Cookies.set('_ga', undefined, {
    expires: -1,
    path: '', // Also tested with /
    domain: `.${document.domain}`
  })
  Cookies.set('_gid', undefined, {
    expires: -1,
    path: '', // Also tested with /
    domain: `.${document.domain}`
  })
  Cookies.set('_gat_gtag_XX_XXXXXXXX_X', undefined, {
    expires: -1,
    path: '', // Also tested with /
    domain: `.${document.domain}`
  })
  
  // This was also tested
  Cookies.remove('_ga', {
    path: '', // Also tested with /
    domain: `.${document.domain}`
  })
  Cookies.remove('_gid', {
    path: '', // Also tested with /
    domain: `.${document.domain}`
  })
  Cookies.remove('_gat_gtag_XX_XXXXXXXX_X', {
    path: '', // Also tested with /
    domain: `.${document.domain}`
  })
}
}

我们已经通过设置和删除了这两种方式尝试了这一点。我们本地计算机上运行的代码完美工作，毫无问题地删除了cookie，但是当我们将完全相同的代码传递给测试服务器时，这些cookie将不会被删除。

有些东西也许我们缺少了？我们找不到什么。
