结果：ReferenceError：未定义响应

Posted 2021-04-05

我正在尝试通过SendGrid + Parse云代码模块的表单发送电子邮件。一切都在功能上很好，电子邮件正在通过。但是，当我查看我的日志时，我得到以下内容：

Result: ReferenceError: response is not defined

//卖弄.就是

var express = require('express');
var sendgrid = require('sendgrid');
sendgrid.initialize("USER", "PASS");

var app = express();

// App configuration section
app.use(express.bodyParser());    // Middleware for reading request body


app.post('/email', function(req, res) {
  var name = req.body.name;
  var email = req.body.email;
  var message = req.body.message;

  sendgrid.sendEmail({
    to: '[e-mail]',
    from: email,
    subject: 'Message from ' + name + ' via Web',
    text: message
  }, {
    success: function(httpResponse) {
      console.log(httpResponse);
      response.success("Email sent!");
    },
    error: function(httpResponse) {
      console.error(httpResponse);
      response.error("Uh oh, something went wrong");
    }
  });
});

答案

response没有定义，我想你打算写

sendgrid.sendEmail({
    to: '[e-mail]',
    from: email,
    subject: 'Message from ' + name + ' via Web',
    text: message
}, {
    success: function(httpResponse) {
      console.log(httpResponse);
      httpResponse.success("Email sent!");
    },
    error: function(httpResponse) {
      console.error(httpResponse);
      httpResponse.error("Uh oh, something went wrong");
    }
});

顺便说一句：你应该总是通过“use strict”设置严格模式 - 这样可以更快地捕获未定义的变量。
