我不斷收到此錯誤:服務工作者錯誤:事件已經回答了
Uncaught (in promise) DOMException: Failed to execute 'respondWith' on 'FetchEvent': The event has already been responded to.
我知道,如果異步東西的獲取函數內的推移該服務人員自動響應,但我不能完全制定出哪些位將是此代碼中的罪犯:
importScripts('cache-polyfill.js');
self.addEventListener('fetch', function(event) {
var location = self.location;
console.log("loc", location)
self.clients.matchAll({includeUncontrolled: true}).then(clients => {
for (const client of clients) {
const clientUrl = new URL(client.url);
console.log("SO", clientUrl);
if(clientUrl.searchParams.get("url") != undefined && clientUrl.searchParams.get("url") != '') {
location = client.url;
}
}
console.log("loc2", location)
var url = new URL(location).searchParams.get('url').toString();
console.log(event.request.hostname);
var toRequest = event.request.url;
console.log("Req:", toRequest);
var parser2 = new URL(location);
var parser3 = new URL(url);
var parser = new URL(toRequest);
console.log("if",parser.host,parser2.host,parser.host === parser2.host);
if(parser.host === parser2.host) {
toRequest = toRequest.replace('https://booligoosh.github.io',parser3.protocol + '//' + parser3.host);
console.log("ifdone",toRequest);
}
console.log("toRequest:",toRequest);
event.respondWith(httpGet('https://cors-anywhere.herokuapp.com/' + toRequest));
});
});
function httpGet(theUrl) {
/*var xmlHttp = new XMLHttpRequest();
xmlHttp.open("GET", theUrl, false); // false for synchronous request
xmlHttp.send(null);
return xmlHttp.responseText;*/
return(fetch(theUrl));
}
任何幫助,將不勝感激。
