app.post('/l',function(req,res){ //创建一个路由,处理登陆的post请求 res.json({code:0}); //给前端相应一个json对象回去 }) 1. 2. 3. 总结 1.Express 提供了内置的中间件 express.static 来设置静态文件如:图片, CSS, JavaScript 等。 你可以使用 express.static 中间
function(req,res){//...} 然后请求都会被app这个函数处理(因为这个app是执行express后的结果,下面将不加区分的使用app和express两个词)。 可以认为,在express内部,有一个函数的数组,暂时叫这个数组tasks,每来一个请求express内部会依次执行这个数组中的函数(这里说依次并不严谨,每个函数必须满足一定条件才行,这个...
One approach is to utilize themiddlewarefunctionality in Express.js. How it works is when a request is made to a specific route, you can have the(req, res)variables sent to an intermediary function before the one specified in theapp.get((req, res) => {}). The middleware is a function...
app.use(express.static('public')); 现在可以加载public目录下的文件了: 比如: http://localhost:3000/image/jkk.png 通过多次使用 express。static中间件来添加多个静态资源目录: app.use(express.static('public')); app.use(express.static('file')); Express将会按照你设置静态资源目录的顺序来查看静态资源...
For example if an index.js file exists next to index.html and the model is not defined by configuration like in the example above, then the index.js file will be used to set the model so long as it exports either an object or a function that returns an object....
In aex, it introduces the function parameter mode like this.async function aexHTTPHandler(req, res, scope) { res.end(); scope.body; scope.inner; }Which we can call it the promis based mode or the aex mode, first introduced by the aex web framework project....

Jest provides a built-in `expect()` global function for making assertions. A basic test could look like this: ```js import sum from './sum'; it('sums numbers', () => { expect(sum(1, 2)).toEqual(3); expect(sum(2, 2)).toEqual(4); }); ``` All `expect()` matchers ...
}// 场景二exportfunctiongetUserList(){returnhttp.get('/user/getList') }// 场景三 如功能名包含了模块名,可省略exportfunctiongetUserList(){returnhttp.get('/user/getUserList') }// 其他exportfunctionsaveUser(data){returnhttp.post('/user/save', data) ...
Because TypeScript at this point is still somewhat immature, there might be some missing, but you can add them in yourself.Figure 2 Examining the winjs.d.ts Definition FileCopy declare module WinJS { export function strictProcessing(): void; export module Binding { export function as(data:...
