在Express-js中使用路由 [英] Using routes in Express-js
问题描述
所以我开始使用Node.js.我看到了Ryan Dahl在 Nodejs.org 上的视频,并听说他推荐了Express-js的网站。
So I'm starting to use Node.js. I saw the video with Ryan Dahl on Nodejs.org and heard he recommended Express-js for websites.
我下载了最新版本的Express,并开始编写代码。我有一个完全成熟的静态查看在/,但一旦我尝试发送参数,我得到这样的错误:
I downloaded the latest version of Express, and began to code. I have a fully fledged static view up on /, but as soon as I try sending parameters, I get errors like this:
Cannot GET /wiki
我尝试按照 expressjs.com ,但是使用路线的方式在最新版本中有所改变,这使得该指南无法使用。
I tried following the guide on expressjs.com but the way one uses routes has changed in the latest version, which makes the guide unusable.
指南:
app.get('/users/:id?', function(req, res, next){
var id = req.params.id;
if (id) {
// do something
} else {
next();
}
});
由Express生成:
Generated by Express:
app.get('/', routes.index);
当我尝试添加其他路线时,出现问题。
My problem arises when I try and add another route.
app.get('/wiki', routes.wiki_show);
我已经尝试了一大堆方法,但是我不断得到 GET / wiki
(404)错误。
I've tried a bunch of approaches, but I keep getting the Cannot GET /wiki
(404) error.
routes / index.js如下所示:
routes/index.js looks like this:
exports.index = function(req, res) {
res.render('index', { title: 'Test', articles: articles, current_article: current_article, sections: sections })
};
我在这里做的唯一的事情是添加一些参数(同一个文件中的数组),这个我工作。但是当我复制内容并将<。c $ c> exports.index 更改为 exports.wiki
或导出。 wiki_show
我仍然得到不能GET / wiki
错误。
The only thing I did there was add some parameters (arrays in the same file) and this i working. But when I copy the contents and change exports.index
to exports.wiki
or exports.wiki_show
I still get the Cannot GET /wiki
error.
任何人都可以解释我在这里缺少什么? - 谢谢。
Can anyone explain to me what I'm missing here? - Thanks.
推荐答案
所以,在我创建了我的问题之后,我在右边找到了相关的列表: a href =https://stackoverflow.com/questions/4602212/organize-routes-in-node-js>组织Node.js中的路由。
So, after I created my question, I got this related list on the right with a similar issue: Organize routes in Node.js.
该链接中的答案与 GitHub快速回购相关联,并建议请查看路线分离示例。
The answer in that post linked to the Express repo on GitHub and suggests to look at the 'route-separation' example.
这有助于我更改代码,现在我可以使用它了。 - 感谢您的意见。
This helped me change my code, and I now have it working. - Thanks for your comments.
我的实现最终看起来像这样;
My implementation ended up looking like this;
我需要我的路线app.js:
I require my routes in the app.js:
var express = require('express')
, site = require('./site')
, wiki = require('./wiki');
我添加了这样的路线:
app.get('/', site.index);
app.get('/wiki/:id', wiki.show);
app.get('/wiki/:id/edit', wiki.edit);
我的应用程序根目录中有两个名为wiki.js和site.js的文件,其中包含:
I have two files called wiki.js and site.js in the root of my app, containing this:
exports.edit = function(req, res) {
var wiki_entry = req.params.id;
res.render('wiki/edit', {
title: 'Editing Wiki',
wiki: wiki_entry
})
}
