由於cors限制,我目前正在努力獲取NodeJS中網頁的HTML源代碼。使用JQuery我正在向預期HTML響應的頁面發出GET請求。然而,這會引發錯誤XMLHttpRequest cannot load https://www.reddit.com/. Response to preflight request doesn't pass access control check: No 'Access-Control-Allow-Origin' header is present on the requested resource. Origin 'http://127.0.0.1:8000' is therefore not allowed access
。有沒有辦法繞過使用NodeJS的CORS? (如通過代理)在NodeJS中獲取頁面的HTML源代碼
$.ajax({
url: 'https://www.reddit.com/',
headers: {
'Content-Type': 'text/html',
"Access-Control-Allow-Origin": '*'
},
type: "GET",
data: {
},
success: function (result) {
console.log(result);
},
error: function() {
console.log("error");
}
});
我還使用具有以下標題的WebPack開發服務器
headers: {
"Access-Control-Allow-Origin": '*',
"Access-Control-Allow-Credentials": "true",
"Access-Control-Allow-Methods": "GET, POST, PUT, DELETE, OPTIONS"
}

不要使用jQuery,使用Node.js的'http'模塊或者像npm這樣的包裝器軟件包'superagent' – Tobsta
