使用节点js获取授权标头令牌 [英] get authorization header token with node js

问题描述

我想在后端节点js中获得令牌.

I would like to get token in backend node js.

首先，我从jwt获取令牌，并将其存储在localstorage中，但是当我想使用此令牌发送请求时，无法在服务器端获取它.

First, I get the token from jwt and I stored in localstorage,but when i would like to send a request with this token, I can't get it in server side.

客户端:

        function list_users(){
            url= "http://localhost:8181/users";
            var tok = window.localStorage.getItem('token');
            if (tok) {
        /*
        $.ajaxSetup({
                    headers: {
                        'x-access-token': tok
                    }
                });
        */

                $.ajax({
                headers: {'Authorization': tok},
                dataType: "application/json; charset=utf-8",
                url,
                type: 'GET',
                dataType: 'json',
                success: function (json) {
    alert("done");
    }
})
}
}

服务器端:

router.use(function(req, res, next) {

res.header("Access-Control-Allow-Origin", "*");
res.setHeader('Access-Control-Allow-Methods', 'GET, POST, OPTIONS, PUT, PATCH, DELETE');  
res.header("Access-Control-Allow-Headers", "Authorization");

console.log(req.headers['authorization']);
...

}

但是

req.headers ['授权']

req.headers['authorization']

打印

未定义"

"undefined"

请提供任何解决方案.

推荐答案

使用如下:

req.header('authorization');
