无法读取未定义的 属性 'username' - 在 Node.js 中通过电子邮件发送表单数据
Cannot read property 'username' of undefined - Sending form data via email in Node.js
我正在尝试创建一个简单的网页,在填写联系表格并按下提交按钮时它应该会发送一封电子邮件。
我正在尝试为此使用 Node.js,但出现以下错误:
这是我到目前为止所做的。

我不知道我在这里错过了什么。如果有人知道如何解决这个问题,请告诉我我需要什么依赖项(如果需要的话)以及我需要在哪里修复我的错误。
亲切的问候
您需要先设置 body-parser
,然后再定义路线。
将您的 Express 应用配置移至 app.post('/contact')
路线之上:
app.set('views', path.join(__dirname, 'views'));
app.set('view engine', 'jade');
app.use(logger('dev'));
app.use(bodyParser.json());
app.use(bodyParser.urlencoded({ extended: true }));
app.use(cookieParser());
app.use(express.static(path.join(__dirname, 'public')));
app.post('/contact', function(req,res){
//....
});
在注册 post
之后注册 bodyparser
。将 app.use
行移到 app.post
之前,我认为它会起作用。
