-_Routing_ refers to determining how an application responds to a client request to a particular endpoint, which is a URI (or path) and a specific HTTP request method (GET, POST, and so on).
+_路由（Routing）_ 指的是确定应用如何响应客户端对特定端点的请求，端点包含一个 URI（或路径）和特定的 HTTP 请求方法（GET、POST 等）。
 
-Each route can have one or more handler functions, which are executed when the route is matched.
+每个路由可以有一个或多个处理函数，当路由匹配时这些函数会被执行。
 
-Route definition takes the following structure:
+路由定义采用以下结构：
 
 ```js
 app.METHOD(PATH, HANDLER);
 ```
 
-Where:
+其中：
 
-- `app` is an instance of `express`.
-- `METHOD` is an [HTTP request method](https://developer.mozilla.org/en-US/docs/Web/HTTP/Reference/Methods), in lowercase.
-- `PATH` is a path on the server.
-- `HANDLER` is the function executed when the route is matched.
+- `app` 是 `express` 的一个实例。
+- `METHOD` 是一个 [HTTP 请求方法](https://developer.mozilla.org/en-US/docs/Web/HTTP/Reference/Methods)，使用小写。
+- `PATH` 是服务器上的路径。
+- `HANDLER` 是路由匹配时执行的函数。
 
 <Alert type="alert">
 
-This tutorial assumes that an instance of `express` named `app` is created and the server is
-running. If you are not familiar with creating an app and starting it, see the Hello world
-example.
+本教程假设已创建一个名为 `app` 的 `express` 实例且服务器正在运行。如果你不熟悉如何创建和启动应用，请参阅 Hello World 示例。
 
 </Alert>
 
-The following examples illustrate defining simple routes.
+以下示例演示了如何定义简单的路由。
 
-Respond with `Hello World!` on the homepage:
+在首页响应 `Hello World!`：
 
 ```js
 app.get('/', (req, res) => {
   res.send('Hello World!');
 });
 ```
 
-Respond to a POST request on the root route (`/`), the application's home page:
+在根路由（`/`），即应用首页，响应 POST 请求：
 
 ```js
 app.post('/', (req, res) => {
   res.send('Got a POST request');
 });
 ```
 
-Respond to a PUT request to the `/user` route:
+响应 `/user` 路由的 PUT 请求：
 
 ```js
 app.put('/user', (req, res) => {
   res.send('Got a PUT request at /user');
 });
 ```
 
-Respond to a DELETE request to the `/user` route:
+响应 `/user` 路由的 DELETE 请求：
 
 ```js
 app.delete('/user', (req, res) => {
   res.send('Got a DELETE request at /user');
 });
 ```

-## How do I define models?
+## 我如何定义模型？
 
-Express has no notion of a database. This concept is
-left up to third-party Node modules, allowing you to
-interface with nearly any database.
+Express 没有数据库的概念。这个概念留给第三方 Node 模块，允许你与几乎任何数据库进行交互。

-## How can I authenticate users?
+## 我如何对用户进行身份验证？
 
-Authentication is another opinionated area that Express does not
-venture into. You may use any authentication scheme you wish.
-For a simple username / password scheme, see [this example](https://github.com/expressjs/express/tree/master/examples/auth).
+身份验证是另一个 Express 不涉及的有争议领域。你可以使用任何你想要的身份验证方案。
+对于简单的用户名/密码方案，请参阅[此示例](https://github.com/expressjs/express/tree/master/examples/auth)。
 
-## Which template engines does Express support?
+## Express 支持哪些模板引擎？
 
-Express supports any template engine that conforms with the `(path, locals, callback)` signature.
-To normalize template engine interfaces and caching, see the
-[consolidate.js](https://github.com/visionmedia/consolidate.js)
-project for support. Unlisted template engines might still support the Express signature.
+Express 支持任何符合 `(path, locals, callback)` 签名的模板引擎。
+要统一模板引擎接口和缓存，请参阅 [consolidate.js](https://github.com/visionmedia/consolidate.js) 项目获取支持。未列出的模板引擎可能仍然支持 Express 签名。

+有关更多信息，请参阅[在 Express 中使用模板引擎](/guide/using-template-engines)。
 
-## How do I handle 404 responses?
+## 我如何处理 404 响应？
 
-In Express, 404 responses are not the result of an error, so
-the error-handler middleware will not capture them. This behavior is
-because a 404 response simply indicates the absence of additional work to do;
-in other words, Express has executed all middleware functions and routes,
-and found that none of them responded. All you need to
-do is add a middleware function at the very bottom of the stack (below all other functions)
-to handle a 404 response:
+在 Express 中，404 响应不是错误的结果，因此错误处理中间件不会捕获它们。这种行为是因为 404 响应仅仅表示没有更多工作要做；换句话说，Express 已执行所有中间件函数和路由，发现它们都没有响应。你只需要在栈的最底部（所有其他函数之下）添加一个中间件函数来处理 404 响应：
 
 ```js
 app.use((req, res, next) => {
   res.status(404).send("Sorry can't find that!");
 });
 ```
 
-Add routes dynamically at runtime on an instance of `express.Router()`
-so the routes are not superseded by a middleware function.
+在 `express.Router()` 实例上在运行时动态添加路由，以便路由不会被中间件函数覆盖。
 
-## How do I setup an error handler?
+## 我如何设置错误处理程序？
 
-You define error-handling middleware in the same way as other middleware,
-except with four arguments instead of three; specifically with the signature `(err, req, res, next)`:
+你定义错误处理中间件的方式与其他中间件相同，只是有四个参数而不是三个；具体签名为 `(err, req, res, next)`：

-## How do I render plain HTML?
+## 我如何渲染纯 HTML？
 
-You don't! There's no need to "render" HTML with the `res.render()` function.
-If you have a specific file, use the `res.sendFile()` function.
-If you are serving many assets from a directory, use the `express.static()`
