[英]How to include JS, CSS and other server-side utils to a HTML page in NodeJs using expressJs?
[英]Refreshing page shows file not found error how to resolve using [angular js + NodeJS/ExpressJS ]
注意:我尝试了与此主题相关的所有问题和答案。 像这样,我尝试了相关的问题并试图解决它,但没有成功。
我正在构建angularJS web-app。 它纯粹基于AngularJS / HTML 5和NodeJS / ExpressJS以及数据库端使用mongo DB,然后出现此问题。
我希望在网址中删除'#'
并刷新页面然后显示当前页面。但是现在显示“未找到404”。我使用这个$locationProvider.html5Mode(true);
和<base href="/" />
但我没有成功。
我知道在URL解决方案中删除#是
$locationProvider.html5Mode(true);
和<base href="/" />
但我使用NodeJS / ExpressJS然后我不能使用。
我的网址
http://localhost:3000/Tutorial/Routing/StateProvider/index.html#/Setting/StudenList
我想要URL
http://localhost:3000/Tutorial/Routing/StateProvider/index.html/Setting/StudenList
笔记:
没有这个解决方案$locationProvider.html5Mode(true);
和<base href="/" />
但我使用NodeJS / ExpressJS然后我想删除#和刷新页面问题解决

Folder Structure directive
.my代码很长,然后我管理片段( 在html和js内 )。 不运行片段因为我插入我的所有代码只是为了理解我的代码是什么错误。

这是因为接收请求的Web服务器查找与服务器上的完整URL匹配的资源,该资源不存在,因为URL的角度部分引用角度应用程序中的路径并需要在客户端浏览器中处理
AngularJS + NodeJS / ExpressJS - 在html5mode中页面刷新后阻止404错误的路由
var express = require('express');
var path = require('path');
var router = express.Router();
// serve angular front end files from root path
router.use('/', express.static('app', { redirect: false }));
// rewrite virtual urls to angular app to enable refreshing of internal pages
router.get('*', function (req, res, next) {
res.sendFile(path.resolve('app/index.html'));
});
module.exports = router;
AngularJS + IIS - URL重写规则以防止在html5mode中页面刷新后出现404错误(对于apache 单击此处 )
<rewrite>
<rules>
<rule name="AngularJS" stopProcessing="true">
<match url=".*" />
<conditions logicalGrouping="MatchAll">
<add input="{REQUEST_FILENAME}" matchType="IsFile" negate="true" />
<add input="{REQUEST_FILENAME}" matchType="IsDirectory" negate="true" />
</conditions>
<action type="Rewrite" url="/" />
</rule>
</rules>
</rewrite>
修复此问题的其他方法
这就是我的应用程序。
如果启用了(HTML5模式)并且requireBase为true,并且不存在基本标记,则在注入$ location时将引发错误。
所以,你需要base
标签。 我试过没有基本标记和requireBase
是假的,但它似乎仍然为我抛出一个错误。
的index.html
<head>
<base href="/">
</head>
app.route.js [Angular.js]
app.config(function($stateProvider, $urlRouterProvider, $locationProvider) {
// This removes '#' and makes URL pretty
$locationProvider.html5Mode({
enabled: true,
requireBase: true
});
// Default path if nothing is matched. State would become 'landing'
$urlRouterProvider.otherwise('/');
$stateProvider
.state('landing', {
url: '/',
templateUrl: "/dashboard/landing/templates/index.html",
controller: 'LandingController'
}).state('about', {
url: '/about',
templateUrl: "/dashboard/about/templates/index.html",
controller: 'AboutController'
});
});
一旦您将自己从'landing'
重定向到'about'
状态并且路由更改为/about
,则只会在浏览器上更改URL,并且服务器不知道这一点。 所以,当你刷新,服务器不知道是什么/about
通路装置。 因此,您需要将路径(或属于angular的路径的任何路径)重定向/about
index.html
,然后angular会将您重定向到/about
自动。
app.js [Express.js]
// dashboard route should deliver templates instead of loading angular JS app so this should come before the next one
app.use('/dashboard', express.static(__dirname + '/public/dashboard'));
// put all the API methods here and separate from the redirection to `index.html`
app.use('/api', routes.apiRoutes);
// all the paths that do not start with `/dashboard` or `/api` is/should be angular route and thus, redirect back to `index.html`
app.get('*', function (req, res) {
res.sendFile(__dirname + '/public/index.html');
});
边注
在另一个应用程序中,我看到一个问题,刷新浏览器在路径末尾附加一个尾部斜杠( /
)和重定向后,Angular应用程序无法识别url /about
vs /about/
so的路径将我重定向回登录页面。
我通过在app.route.js中添加它来解决这个问题
$urlMatcherFactoryProvider.strictMode(false);
我希望这有帮助
您必须更改application-configuration.js文件,如下所示:
请找到这个部分:“indexController”
var indexController = function ($scope, $rootScope, $http, $location, blockUI) {
var baseUrl="/Tutorial"; //here it will be your site name
}
只需在您的网址链接中添加此baseUrl即可。
嗯......这个问题是每个人在使用node.js和angular开始时可能会遇到的问题。
第一个问题是网址中的“#”,就像所有人建议的那样
$locationProvider.html5Mode(true);
现在刷新问题将会发生,预计......再次发生。
为什么会这样?
请求被发送到node.js服务器,没有任何地方可以阻止它。
只需确保相应的尾随请求映射到主角度视图。 如果整个程序只有一个ng-app
,那么只需重定向到主视图。
在node.js服务器上添加类似的东西
app.get('/', function(req, res) {
res.sendFile(__dirname + '/index.html');
});
app.get('/*', function(req, res) {
res.sendFile(__dirname + '/index.html');
});
这里index.html
是我的主视图,它链接到主控制器文件,其中存在路由代码。 如果我正在尝试加载/about
它将转到控制器,然后控制器将加载特定的视图。
这是解决此问题的简便方法。
