Question

我正在向启用了CORS的端点发送请求，并通过javascript调试器控制台查看以下标头：

Access-Control-Allow-Headers:Origin, X-Requested-With, Content-Type, Accept, X-Username, X-Password, X-Auth-Token
Access-Control-Allow-Methods:GET,POST
Access-Control-Allow-Origin:*
Cache-Control:no-cache, no-store, max-age=0, must-revalidate
Content-Length:0
Date:Fri, 19 Jan 2018 00:10:04 GMT
Expires:0
Pragma:no-cache
X-Auth-Token:re6X3wiUlbZMiN0443u1E5OmCa1zad0UAI6ygDCRqj8=
X-Content-Type-Options:nosniff
X-Frame-Options:DENY
X-Something:Value
X-XSS-Protection:1; mode=block

我在服务器上设置它们，这是预期的。

当我用fetch打印它们时

fetch("http://localhost:8080/api/1.0/data/people",
        {
            mode: 'cors',
            method: "POST",
            body: data,
            headers: {
                'X-Username': 'e4080',
                'X-Password': 'e4080',
                'Accept': 'application/json',
                'Content-Type': 'application/json',
            }
        })
        .then(function (res) {
            var hdr = ""
            for (var pair of res.headers.entries()) {
                console.log(pair[0]+ ': '+ pair[1]);
            }
        })

我只能得到这个：

cache-control: no-cache, no-store, max-age=0, must-revalidate
auth-actions.js:103 expires: 0
auth-actions.js:103 pragma: no-cache

为什么我看不到所有的标题？具体来说，为什么我看不到X-Auth-Token标题？

isomorphic fetch不打印javascript调试器显示的所有头文件
