Question

请问 JavaScript 能获取 当前网页的请求头吗？ Request Hearders ，而不是 Response Hearders 。

heart_dict = {
    'accept':'application/json, text/javascript, */*; q=0.01',
    'accept-encoding':'gzip, deflate, br',
    'accept-language':'zh-CN,zh;q=0.9',
    'content-length':'309',
    'content-type':'application/x-www-form-urlencoded; charset=UTF-8',
    'origin':'https://trade.xxxx.com',
    'referer':'https://trade.xxxx.com/trade/itemlist/list_sold_items.htm?spm=686.1000925.a1zvx.d28.9VG8CJ&mytmenu=ymbb',
    'sec-fetch-dest':'empty',
    'sec-fetch-mode':'cors',
    'sec-fetch-site':'same-origin',
    'user-agent':'Mozilla/5.0 (Windows NT 6.1; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/83.0.4103.97 Safari/537.36',
    'x-requested-with':'XMLHttpRequest',
}

Answer 1

1. 没图
2. 可以取到一部分，不过是通过其它途径，比如 userAgent 之类。无法完整获取当前页面请求头。
