如何从Node js Side获取基本path？
注意：我尝试了所有与此主题相关的问题和解答，但是无法解决问题。
我想从Node Js Side的基础path。 下面的例子。 我使用[angular js + NodeJS / ExpressJS]
<base href="/Tutorial/Routing/StateProvider/" /> HTML
<!DOCTYPE html> <html ng-app="myapp2"> <title>Index | Angular Js</title> <base href="/Tutorial/Routing/StateProvider/" /> <link href="//maxcdn.bootstrapcdn.com/bootstrap/3.3.5/css/bootstrap.min.css" rel="stylesheet"> <script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.4.8/angular.min.js"></script> <!--<script src="//ajax.googleapis.com/ajax/libs/angularjs/1.4.8/angular-route.js"></script>--> <script src="https://cdnjs.cloudflare.com/ajax/libs/angular-ui-router/0.3.2/angular-ui-router.js"></script> <script src="StateProviderController.js"></script> <body > <nav class="navbar navbar-default row"> <div class="container-fluid"> <div class="navbar-header"> <a class="navbar-brand" ui-sref="TutorialHome"> State Routing</a> </div> <ul class="nav navbar-nav"> <li><a ui-sref="Profile">Profile</a></li><!--State Transition on click--> <li><a ui-sref="Account">Account</a></li><!--State Transition on click--> <li><a ui-sref="Setting">Setting</a></li><!--State Transition on click--> <li style="float: right;"><a ui-sref="Home">Home</a></li><!--State Transition on click--> </ul> </div> </nav>
控制器Js
var myapp= angular.module('myapp2',["ui.router"]); myapp.config(function($stateProvider,$urlRouterProvider,$locationProvider,$urlMatcherFactoryProvider){ $urlMatcherFactoryProvider.strictMode(false); $stateProvider .state('TutorialHome', { url:'/index', templateUrl:'/index.html' }) .state('Home',{ url:'/', templateUrl:'http://localhost:3000/' }) .state('Profile',{ url:'/Profile', templateUrl:'Profile.html' }) .state('Account',{ url:'/Account', templateUrl:'Account.html' }) .state('Setting',{ url:'/Setting', templateUrl:'Setting.html' }) .state('Setting.StudenListing', { url:'/StudenList', views: { 'StudenListing': { templateUrl: 'StudenListing.html', controller:'StudentListingData' } } }) .state('Setting.StudenListing.StudentList',{ url:'/StudenList/:StudentID', /* templateUrl: 'StudentDetails.html', controller:'StudentDetails'*/ views:{ 'StudentDetails': { templateUrl: 'StudentDetails.html', controller:'StudentDetails' } } }) ; // $urlRouterProvider.otherwise('/index'); $locationProvider.html5Mode(true); }); myapp.controller('StateProviderCtrl',function($scope){ $scope.message ="Welcome To State Provider Page"; }); myapp.controller('StudentListingData',function($scope,$http){ console.log('test'); $http.get('/StudenRecordData').success(function(response){ // console.log(response); $scope.StudentRecorddata =response; }) }); myapp.controller('StudentDetails',function($scope,$http,$stateParams){ $scope.StudentID = $stateParams.StudentID; //console.log( $scope.StudentID); $http.get('/StuentRecordSearch/'+ $stateParams.StudentID).success(function(response){ //console.log(response); $scope.StuentDetails =response[0]; }) });
app.js
var express = require('express'); var path = require('path'); var favicon = require('serve-favicon'); var logger = require('morgan'); var cookieParser = require('cookie-parser'); var bodyParser = require('body-parser'); var url =require('url'); var index = require('./routes/index'); var app = express(); // view engine setup app.set('views', path.join(__dirname, 'views')); app.set('view engine', 'jade'); // uncomment after placing your favicon in /public //app.use(favicon(path.join(__dirname, 'public', 'favicon.ico'))); app.use(logger('dev')); app.use(bodyParser.json()); app.use(bodyParser.urlencoded({ extended: false })); app.use(cookieParser()); app.use(express.static(path.join(__dirname, 'public'))); app.use('/', index); app.get('/*',function(req,res){ console.log('node js request call'); var pathname2 = url.parse(req.url); console.log('pathname-1:'+pathname2); console.log('pathname-2:'+__dirname); console.log('pathname-3:'+__filename); console.log(url.parse(index)); //console.log('basw path:'+process.env.PWD); res.sendFile(path.resolve('public/index.html')); }); // catch 404 and forward to error handler app.use(function(req, res, next) { var err = new Error('Not Found'); err.status = 404; next(err); }); // error handler app.use(function(err, req, res, next) { // set locals, only providing error in development res.locals.message = err.message; res.locals.error = req.app.get('env') === 'development' ? err : {}; // render the error page res.status(err.status || 500); res.render('error'); }); module.exports = app;
使用cheerio模块提取服务器端的DOM。
创buildutility.js
var cheerio = require('cheerio'); var fs = require('fs'); var utility = { getBasePath : function (filePath) { fs.readFile(filePath, function (err, html) { if (err) { throw err; } else { $ = cheerio.load(html.toString()); return $('base').attr('href'); } }); } }; module.exports = utility;
