在命令行上,我可以执行如下请求: curl -I -H "Fastly-Debug: 1"
它会从为该 URL 提供服务的 CDN 中返回许多有用的信息,在本例中为 Fastly:

如何在节点中执行此操作?
这是我的尝试:
const headers = {
'Fastly-Key': environment.getFastlyToken(),
'Accept': 'application/json',
'Content-Type': 'application/json',
'Fastly-Debug': 1
};
async retrieveSurrogateKey(url) {
console.log("this is the url: ", url)
try {
request({
method: `GET`,
url: url,
headers: headers,
}, function(err, response, body) {
if (err){
console.trace(err)
}
console.log(request.headers)
})
} catch (error) {
console.log("error in retrieval: ", error)
}
}
有没有办法让我传入 -I 和 -H 标志?
