Question

我正在尝试将cookie添加到另一个get请求中的响应对象（res）。但是，如果尝试以下操作，则会给我一个错误，在发送标头后无法设置标头。我假设通过调用“请求”已经发送了报头，如何使用来自单独的get请求的数据将cookie添加到响应对象？同步性质也不会让我将数据保存在get请求之外。我正在使用npm btw的请求模块，谢谢。

/* GET home page. */
router.get('/', function(req, res, next) {
    process.env['NODE_TLS_REJECT_UNAUTHORIZED'] = 0
    var status = "Not currently logged in.";
    if (req.cookies.token !== undefined) {
      status = "Currently Logged in.";
    }
    if (req.cookies.email !== undefined) {
      request('https://localhost:44338/api/customer/' + req.cookies.email 
      {json: true}, (err, response, body) => {
        res.cookie('user', body[0].customerID, {maxAge: 9000000});
        //console.log(body);
      });
    }
    res.render('index', { title: 'Mighty Morphin Store', data: "", status: status});
});

设置cookie后，您必须在回调函数中发送响应。

/* GET home page. */
router.get('/', function(req, res, next) {
    process.env['NODE_TLS_REJECT_UNAUTHORIZED'] = 0
    var status = "Not currently logged in.";
    if (req.cookies.token !== undefined) {
      status = "Currently Logged in.";
    }
    if (req.cookies.email !== undefined) {
      request('https://localhost:44338/api/customer/' + req.cookies.email 
      {json: true}, (err, response, body) => {
        res.cookie('user', body[0].customerID, {maxAge: 9000000});
        //console.log(body);
        res.render('index', { title: 'Mighty Morphin Store', data: "", status: status});
      });
    }

});

将Cookie添加到节点JS中的get请求中的响应对象？
