ServeMe是一个 DSL 用于利用nodejs创建简单的Web应用程序。 - ServeMe = require('serve-me')();
- ServeMe.start(3000);
其选项可以在ServeMe加载时设置，默认它将使用文件夹 "./public" 和文件 "index.html". - //Require the module
- ServeMe = require("serve-me");
- //Set the options
- ServeMe = ServeMe({
- debug: true,
- /**If debug mode is enabled, it will load each file again every http request, else the files will wait in cache.
- * Also prints more logs
- **/
- log: true,
- //(Optional) If log is enabled the server reports all the files served and more information.
- home: "mypage.html",
- //(Optional) home will change the html file served in "/" (by default: 'index.html')
- directory: "./www",
- //(Optional) directory will change the default public folder ('./public')
- error: {
- 404: "404.html",
- 500: "500.html"
- /**Error pages depending on the error code.
- * That specified files must exist in the 'public/error' folder.
- * Model: 'errorcode': "file.html"
- **/
- },
- //(Optional)
- secure: false,
- //Will use https when enabled.
- //ATENTION: A key and a certificate must be provided.
- //By default serve-me will use:
- key: "./keys/key.pem",
- cert: "./keys/cert.pem",
- });
- //Start the server
- ServeMe.start(3000);//3000 is the port. Of course you can change it.
Routes
To add specific actions to url paths ServeMe includes Routes.
Create a route example: - ServeMe.Routes.add("/hello", function(){
- return "Hello World!";
- });
Delete a route example: - ServeMe.Routes.reset("/hello");
To add actions to specific events yo can use the ServeMe Events. - ServeMe.on("event_name", function(data){
- console.log("I am an event!");
- });
"event_name" is the name required to select de action wanted.
These are the available events for now:
"http_request": Will be called each http connection.
"new_session": Will be called when a new session can be created.
"end_session": Will be called when an existing session lifetime ends.
"session": Will be called when an existing session connects.
"error": Will be called when an error appears.
If you want to create your own event, you can activate it with: - ServeMe.call("event_name");
The sessions have been implemented to facilitate the creation of user sessions or similar tasks, mainly using cookies.
First of all we need to enable sessions in the serveme options: - ServeMe = ServeMe({
- debug: false,
- sessions:{
- enabled: true, //Enable sessions
- persistence: true, //if false disables the lifetime, and the session never ends (default true)
- lifetime: 86400, //Life of the session in seconds (default: 1 day)
- new_session_url: "/session/new", //Url selected to create sessions
- //new session petition will be created each visit
- }
- });
Then "session/new" will reqistry each visitor in a new session. But one more step is needed. To alow the customization of the session registry you can use the "new_session" event like this: - var username = "bear",
- password = "drowssap";
- ServeMe.on("new_session", function(new_session){
- //new_session.data contains all the url arguments.
- //Login example:
- if( new_session.data.username == username &&
- new_session.data.password == password)
- {
- //if there are the correct credentials allow a new session creation, returning true.
- return true;
- }
- //else returning false.
- return false;
- });
session.data contains all the url arguments, for example a session request like - /session/new?user=bear&password=drowssap
will give us that session.data: - >{
- > user: "bear",
- > password: "drowssap"
- >}
