Duba fitarwar IP da aka gani daga Chrome extension

Aika buƙata mai iyaka daga asalin extension ɗin zuwa wani ƙarshen da ka sarrafa, sannan ka bayyana abin da gwajin ya tabbatar da gaske.

Gwajin proxy a cikin Chrome extension yana buƙatar wuri mai amsa da za a iya tsammani. Yi amfani da HTTPS endpoint da kake sarrafawa, misali wanda ke mayar da ƙaramin JSON abu mai ɗauke da adireshin da yake gani.

Gudanar da buƙatar daga mahallin extension, kamar service worker ɗinsa ko shafin extension, sannan sanya endpoint ɗin a cikin host permissions na manifest:

"host_permissions": ["https://probe.example/*"]

Izinin host ba ya ba content script irin wannan damar ketare-asali. Ka riƙe gwajin a cikin mahallin extension maimakon ɗauka cewa script da aka saka zai iya yin irin wannan buƙatar.

async function probe() {
  const controller = new AbortController();
  const timer = setTimeout(() => controller.abort(), 5000);
  try {
    const response = await fetch('https://probe.example/ip', {
      cache: 'no-store',
      signal: controller.signal,
    });
    if (!response.ok) throw new Error(`HTTP ${response.status}`);
    const result = await response.json();
    if (typeof result.ip !== 'string') throw new Error('Bad probe body');
    return result.ip;
  } finally {
    clearTimeout(timer);
