在Firebase中看不到请求标头的值? [英] Can't see value of request headers in firebase?

问题描述

我执行以下操作:

var headers = new Headers();
headers.append("bunny", "test");
headers.append("rabbit", "jump");
fetch("blahurl.com/someservice", {headers:headers})

在火力基地上:

export const listener = functions.https.onRequest(async (req, res) => {
 for (let entry of req.rawHeaders) {
        console.log(entry); // here I see a 'bunny,rabbit' get printed somewhere
    }

     //However this yields undefined:
     req.headers.bunny

不确定如何获取标头值，我只有标头...

Not sure how to get the header values, I just have the headers...

推荐答案

问题似乎出在cors上，因此将函数的主体移入其中是可行的，就像这样:

Looks like the issue was with cors, so moving the body of the function into it worked, like so:

const cors = require('cors')({ origin: true });

export const listener = functions.https.onRequest(async (req, res) => {
    cors(req, res, () => {

然后cookie开始正确显示...

And then the cookies started appearing correctly...

我不确定为什么，这不是响应，而只是请求.

I'm not entirely sure why though, this isn't a response thing it's just a request.
