AngularJS 使用 HTML5 模式路由 404 错误

Question

我刚开始使用 angular js，我尝试了路由并且工作得很好。问题是当我刷新页面时它显示 404 错误，因为它正在签入我的实际目录而不是签入路线。

这里是完整的代码

<!DOCTYPE html>
<html>
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.23/angular.min.js"></script>
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.4.8/angular-route.js"></script>

<body ng-app="myApp">

  <base href="/" />

  <a href="blue">blue</a>

  <a href="green">green</a> //blue.html and green.html are in same directory as index.html

  <p>Click on the links to load blue or green.</p>

  <div ng-view></div>

  <script>
    var app = angular.module("myApp", ["ngRoute"]);

    app.config(function($routeProvider, $locationProvider) {
      $routeProvider
        .when("/blue/:name?", {
          templateUrl: "blue.html",
          controller: "blue_control"
        })

        .when("/green", {
          templateUrl: "green.html",
          controller: "green_control"
        })

      $locationProvider.html5Mode({
        enabled: true
      });

    });
    app.controller("blue_control", function($scope) {
      $scope.msg = "this is blue";
    });
    app.controller("green_control", function($scope) {
      $scope.msg = "this is green";
    });
  </script>


</body>

</html>

这是浏览器输出

这是我刷新的时候

请提供一些解决方案。

Answer 1

问题是您没有将变量 $routeProvider 分配给您的控制器，这导致控制器无法访问变量 $routeParams

试一试

 /*app.controller("blue_control", function($scope) {

      $scope.msg = "this is blue";
    });
    app.controller("green_control", function($scope) {
      $scope.msg = "this is green";
    });*/
 app.controller("blue_control", function($scope,$routeParams) {
     console.log( $routeParams.term_user);
      $scope.msg = "this is blue";
    });
    app.controller("green_control", function($scope,$routeParams) {
      $scope.msg = "this is green";
    });

UPDATE

我认为你不能使用低版本angulajs的路由版本请更改 angularjs 的更高版本，例如

/* <script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.23/angular.min.js"></script>*/

<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.6.4/angular.min.js"></script>

<!DOCTYPE html>
<html>


<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.6.4/angular.min.js"></script>
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.4.8/angular-route.js"></script>

<body ng-app="app">

  <base href="/#/" />

  <a href="#/blue">blue</a>

  <a href="#/green">green</a> //blue.html and green.html are in same directory as index.html

  <p>Click on the links to load blue or green.</p>

  <div ng-view></div>

  <script>
    var app = angular.module("app", ['ngRoute']);

    app.config(function($routeProvider) {
      $routeProvider
        .when("/blue/:name?", {
          templateUrl: "blue.html",
          controller: "blue_control"
        })

        .when("/green", {
          templateUrl: "green.html",
          controller: "green_control"
        })

      

    });
    app.controller("blue_control", ['MyFirstController',function($scope, $routeParams) {
      $scope.msg = "this is blue";
    }]);
    app.controller("green_control", ['MyFirstController2',function($scope, $routeParams) {
      $scope.msg = "this is green";
    }]);
  </script>


</body>

</html>

HTML5模式需要URL重写。

来自文档：

HTML5 Mode

Server side

Using this mode requires URL rewriting on server side, basically you have to rewrite all your links to entry point of your application (e.g. index.html). Requiring a <base> tag is also important for this case, as it allows AngularJS to differentiate between the part of the url that is the application base and the path that should be handled by the application.

— AngularJS Developer Guide - Using $location (HTML5 Mode Server Side)

对于 NodeJS 和 ExpressJS

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;

对于 Windows

上的 IIS

<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>

看，How do I configure IIS for URL Rewriting an AngularJS application in HTML5 mode?

对于阿帕奇

RewriteEngine On RewriteCond %{DOCUMENT_ROOT}%{REQUEST_URI} -f [OR] 
RewriteCond %{DOCUMENT_ROOT}%{REQUEST_URI} -d
RewriteRule ^ - [L]
RewriteRule ^

我在使用 http-server 作为我的本地网络服务器时遇到了同样的问题，这是 html5 的一个已知问题，在 angular-ui/ui-router FAQ.

中有详细说明

我使用以下命令切换到 Nginx（通过 apt-get 安装）/etc/nginx/sites-enabled/default

server {
    listen 80 default_server;
    listen [::]:80 default_server;

    #root /var/www/html;

    root /home/conor/workspace/code_institute/route_test;

    # Add index.php to the list if you are using PHP
    index index.html index.htm index.nginx-debian.html;

    #server_name _;
    server_name localhost;

    location / {
        # First attempt to serve request as file, then
        # as directory, then fall back to displaying a 404.
        #try_files $uri $uri/ =404;
        try_files $uri $uri/ /index.html;
    }

 }

修改后为start/stop/reload；

sudo service nginx <start|stop|status>
