Web.js framework for Node.js

• 实现了URL路由功能
• 实现GET和POST的HTTP请求响应
• 实现自定义404页面
• 实现GET和POST响应器出错时的备用错误处理器
• 引用Mustache模版引擎的方法

一个小DEMO

先把web文件夹复制到你的项目里，然后require(‘./web/web’)就行了。

URL路由映射设置

var qs = require("querystring"),
    web = require("./web/web");

var urls = {
            "test" : "simple.txt",
            "test/([a-zA-Z0-9])" : "test.html",
            "^[0-9]" : "testimage.jpg"
            };

web.run(urls, 8888, "127.0.0.1");
console.log("It's running on http://localhost:8888");

上面这段代码做了一个简单的HTTP服务器和URL路由映射功能(支持正则):

1. 当浏览http://localhost:8888/的时候就会看到主页
2. 当浏览http://localhost:8888/test/的时候就会返回simple.txt里面的内容
3. 当浏览http://localhost:8888/test/+任意字符(如http://localhost:8888/test/foo)的时候就会返回test.html
4. 当浏览http://localhost:8888/+任意数字的时候就会返回一个名为testimage.jpg的图片

GET和POST的响应器设置

var qs = require("querystring"),
    web = require("./web/web");

var urls = {
            "test" : "simple.txt",
            "test/([a-zA-Z0-9])" : "test.html",
            "^[0-9]" : "testimage.jpg"
            },
    gets = {
            "get" : function (req, res, qs) {
                        var qss = "";
                        for (var key in qs) {
                            qss += key + ":" + qs[key] + "
";
                        }
                        web.send(res, 'Test the GET
' + qss);
                    },
            "a" : function (req, res, qs) {
                        gt;
                    }
            },
    posts = {
            "post" : function (req, res, data) {
                        web.send(res, "POST success.");
                    }
            };w

eb.run(urls, 8888, "127.0.0.1");
web.get(gets);
web.post(posts);

console.log("It's running on http://localhost:8888");

这里定义了两个Object，和URL规则一样，但是不支持正则(出于性能考虑)，值需要是一个callback函数，需要传入三个参数：Request、Response、Data(一个包含请求内的数据的Obj，当中的set函数请无视。。)。

自定义404页面

set404方法，只需要传入一个指定404文件的文件名就可以了。

var qs = require("querystring"),
    web = require("./web/web");

var urls = {
            "test" : "simple.txt",
            "test/([a-zA-Z0-9])" : "test.html",
            "^[0-9]" : "testimage.jpg"
            },
    gets = {
            "get" : function (req, res, qs) {
                        var qss = "";
                        for (var key in qs) {
                            qss += key + ":" + qs[key] + "
";
                        }
                        web.send(res, 'Test the GET
' + qss);
                    },
            "a" : function (req, res, qs) {
                        gt;
                    }
            },
    posts = {
            "post" : function (req, res, data) {
                        web.send(res, "POST success.");
                    }
            };

web.run(urls, 8888, "127.0.0.1");
web.get(gets);
web.post(posts);
web.set404("404.html");

console.log("It's running on http://localhost:8888");

GET和POST错误设置

var qs = require("querystring"),
    web = require("./web/web");

var urls = {
            "test/([a-zA-Z0-9])" : "test.html",
            "[0-9]" : "testimage.jpg"
            },
    gets = {
            "get" : function (req, res, qs) {
                        var qss = "";
                        for (var key in qs) {
                            qss += key + ":" + qs[key] + "
";
                        }
                        web.send(res, 'Test the GET
' + qss);
                    },
            "a" : function (req, res, qs) {
                        gt;
                    }
            }
    posts = {
            "post" : function (req, res, data) {
                        web.send(res, "POST success.");
                    }
            },
    erorrs = {
            "get" : function (req, res) {
                        web.send(res, "Get handler has gone wrong");
                    },
            "post" : function (req, res) {
                        web.send(res, "Post handler has gone wrong");
                    }
            };

web.run(urls, 8888, "127.0.0.1");
web.get(gets);
web.post(posts);
web.set404("404.html");
web.erorr(erorrs);

console.log("It's running on http://localhost:8888"); 

还是一样的用法，但是是一个get属性和post属性，传入Request和Response。

嗯，今天先到这里。。以后更新了再补充。。塞哟拉拉
