刷新页面显示文件未找到错误如何解决使用[angular js + NodeJS/ExpressJS]

Question

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.

我想 '#'在URL中移除,我刷新页面,然后显示我的当前页面.但现在显示"404未找到"像这样的.我使用$locationProvider.html5Mode(true);和<base href="/" />,但我不是成功.

我知道删除#在URL的解决方案是$locationProvider.html5Mode(true);与 <base href="/" />但我用的NodeJS/ExpressJS我就不能使用.

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);, <base href="/" />但我使用NodeJS/ExpressJS然后我想删除#和刷新页面问题解决

码

Folder Structure directive.my代码很长,然后我mange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解我的代码是什么错误.

Answer 1

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且需要在客户端浏览器中处理

解决此问题的方法是将所有虚拟URL重写为主角度index.html文件

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>

Answer 2

这就是我的应用程序.

来自HTML 文档的API文档

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.我试过没有基本标签并且requireBase是假的,但它似乎仍然给我带来了错误.

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'
        });

});

一旦您将自己重定向'landing'到'about'状态并且路由更改为/about,则仅在浏览器上更改URL,并且服务器不知道这一点.因此,当您刷新时,服务器不知道/about路径的含义.因此,您需要将/about路径(或属于angular的路径的任何路径)index.html重定向到,然后angular会将您重定向到/about自动状态.

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应用程序无法识别来自url /aboutvs 的路径,/about/因此它将我重定向回到着陆页.

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
