Ant*_*yrd 16 routing node.js express
我正在尝试在我的快递应用程序中添加新路由,但在尝试启动服务器时我一直收到错误.错误是
C:\development\node\express_app\node_modules\express\lib\router\index.js:252
throw new Error(msg);
^
Error: .get() requires callback functions but got a [object Undefined]
这是我的文件,我是节点的新手,所以如果我遗漏了一个重要文件,请告诉我
路线/ furniture.js
exports.furniture = function(req, res){
res.render('furniture', { title: '4\267pli' });
};
路线/ index.js
/*
* GET home page.
*/
exports.index = function(req, res){
res.render('index', { title: '4\267pli' });
};
意见/ furniture.ejs

麻烦是:
routes = require('./routes'),
user = require('./routes/user'),
furniture = require('./routes/furniture'),
这三个是设置你的路由文件夹,而不是一个特定的文件,快递将寻找index.js(找不到,然后 - >错误)
在这些文件夹中,您应该将index.js与您的:
exports.xxxx = function(req, res){
res.render('xx', { foo: foo});
};
然后,您的项目文件夹结构应如下所示:
routes/
??? index.js
?
??? user/
? ??? index.js (with a exports.user inside)
?
??? fourniture/
??? index.js (with a exports.furniture inside)
您可以将多个导出功能添加到这样的路线:
app.js
// a folder called routes with the index.js file inside
routes = require('./routes')
.
.
.
app.get('/', routes.main_function);
app.get('/sec_route', routes.sec_function);
app.post('/other_route', routes.other_function);
/routes/index.js
exports.main_function = function(req, res){
res.render('template1', { foo: foo });
};
exports.sec_function = function(req, res){
res.render('template2', { bar: bar });
};
exports.other_function = function(req, res){
res.render('template1', { baz: baz });
};
如果您的网站有时太大,我更喜欢做以下事情:
routes/furniture.js:
module.exports = function(app)
{
app.get("/furniture/", function(req, res) {
res.render('furniture', { title: '4\267plieee' });
});
}
然后在app.js:
require("./routes/furniture")(app);
它主要是相同的,但app.js将更清洁.
