javascript - 发送电子邮件时出现 Node.js 404 错误，忽略了我的 res.status

Question

我有一个 Angular 应用程序，其形式可以发出 ajax 请求。电子邮件工作正常，但无论我将回复设置为什么；我收到路径错误。我假设 Node 期望路径“/send”呈现模板或数据，但我只想要电子邮件的路径!~我为表单使用模式弹出窗口，为路径使用 Angular ui 路由。

app.get('/send', function (req, res, err) { 
  var cartContent = req.body.slice(1,20);
  var content = tableify(cartContent);
  var sendit = {
    to: '*****@gmail.com',
    from: '****@bluenightphoto.com',
    replyTo: req.body[0].email,

    subject: "CP Carpet Quote Request: " + req.body[0].fname + " " + req.body[0].lname , // REQUIRED.

    html: '<b>Customer Quote</b>' + '<br>' + 'Customer Name: ' + req.body[0].fname + " " +
    '<br>' + 'Message: ' + req.body[0].message + '<br>' + <b>Table</b>'+ '<br><br>' + content,
  };

  // Transporter refers to nodemailer and sendit is the login details(mail works fine!)

  transporter.sendMail(sendit, function (req, res, err) {
    if (err) {
      console.log(err + "something strange...");
      res.status(401).send("that's all folk's");
    } else {
      res.status(200).send("nuthing here");
      console.log("Message sent! " );
    }

    transporter.close();
  });
});

但我的错误处理程序总是收到 404 响应，即使电子邮件发送成功也是如此。

编辑:尝试了下面的两个解决方案，没有用。

这是angular ajax代码

var makeForm = function () {
                if (mailJson[1].total !== 0) {
                    deferred.resolve(mailJson);
                    console.log('values loaded successfully again');


                    $http({
                        method : 'GET',
                        url : '/send',
                        data : mailJson,
                        headers : {
                            'Content-type' : 'application/json'
                        }
                    }).success(function () {
                        console.log('success!');
                        $scope.alertEmailOk = true;
                    }).error(function (err) {
                        console.log('there was an error indeed ' + err);
                        $scope.alertEmailOk = false;
                    });
                } else {
                    console.log('no values!');
                    deferred.reject(mailJson);
                }
                return deferred.promise;
            };

console.log('确实有错误' + err);总是触发..也许我需要发回数据？

这是我的 express 代码中的错误处理程序:

if (app.get('env') === 'production') {

    // changes it to use the optimized version for production
    app.use('/', express.static(path.join(__dirname, '/dist')));

    // production error handler
    // no stacktraces leaked to user
      app.use(function(err, req, res, next) {
        res.status(err.status || 500);
        res.render('error', {
            message: err.message,
            error: err
        });
    });
}

// Transporter refers to nodemailer and sendit is the login details(mail works fine!)

我已经阅读了您的评论，但首先要确定下一部分: 来自 nodemailer

var nodemailer = require('nodemailer');
var transporter = nodemailer.createTransport({
    service: 'gmail',
    auth: {
        user: 'sender@gmail.com',
        pass: 'password'
    }
});
var sendIt = { //<------ i've just renamed this compare to nodemailer.com sample 
    from: 'sender@address',
    to: 'receiver@address',
    subject: 'hello',
    text: 'hello world!'
};


// this part is very important !
// note the signature.
transporter.sendMail(sendIt, function(error, info){
    if(error){
        return console.log(error);
    }
    console.log('Message sent: ' + info.response);

});

所以现在尝试将其插入您的代码中:

//app.get('/send', function (req, res, err) { 
app.get('/send', function (req, res, next) { 

  var cartContent = req.body.slice(1,20);
  var content = tableify(cartContent);
  var sendit = {
    to: '*****@gmail.com',
    from: '****@bluenightphoto.com',
    replyTo: req.body[0].email,

    subject: "CP Carpet Quote Request: " + req.body[0].fname + " " + req.body[0].lname , // REQUIRED.

    html: '<b>Customer Quote</b>' + '<br>' + 'Customer Name: ' + req.body[0].fname + " " +
    '<br>' + 'Message: ' + req.body[0].message + '<br>' + <b>Table</b>'+ '<br><br>' + content,
  };

  // Transporter refers to nodemailer and sendit is the login details(mail works fine!)
  //     |                 
  //     |
  //     v
  // Transporter refers to the login details and sendit to the mail options


  transporter.sendMail(sendit, function (error, info) {// instead of (req, res, err) {
    if (error) { // instead of err just to avoid colision name
      console.log(error + "something strange...");
      res.status(401).send("that's all folk's");
    } else {
      res.status(200).send("nuthing here");
      console.log("Message sent! " );
    }

    transporter.close();
  });

return next();
});

在你的代码中，你的问题在这里:

transporter.sendMail(  sendit, function (  req, res, err)  {
//transporter.sendMail(sendit, function (error, info) {

    if (err) { 
      console.log(err + "something strange...");
      res.status(401).send("that's all folk's");

      // you are acting here on the 'info' coming from transporter.sendMail
     // not on 'res' from app.get('/send',      


    } else {
      res.status(200).send("nuthing here");
      console.log("Message sent! " );


      // you are acting here on the 'info' coming from transporter.sendMail
     // not on 'res' from app.get('/send',      

    }
