Javascript 检查API中节点是否存在电子邮件

导言

好的，我有三个功能。前两个为第三个生成数据

获取帖子数据（电子邮件）

获取API密钥

使用API密钥、用户密钥和电子邮件并将它们发布到API

我需要什么

我需要第三个打印以下到我的控制台提供电子邮件存在

 else {
                    console.log("Login successful !");
                    console.log("API Key", api);
                    console.log("userKey", userkey);
                    console.log("useremail", login_email);
                    console.error("Third You have logged in !");
                }

我得到的

错误空值

即使我发布了一封存在的电子邮件，我还是收到了这封邮件。有人看到我的代码哪里出错了吗

节点代码

var firstFunction = function () {
    var promise = new Promise(function (resolve) { // may be redundant
        setTimeout(function () {
            app.post('/test.js', function (req, res) {
                console.log(req.body);
                // Get varibles from the post form
                var login = req.body.LoginEmail;
                // res.send(email_user);
                res.send(login);
                //resolve when get the response
                resolve({
                    data_login_email: login
                });
            });
            console.error("First done");

        }, 2000);

您的if条件是错误的

（！error&&response.statusCode==200）

应该是：如果有错误或状态不是200，那么

error | | response.statusCode=200

很好，我现在加上这个谢谢
