Angular 路由在与 Google App Engine 和 Flask 一起使用时不起作用

Question

我想做什么：

我正在尝试在 Google App Engine 上构建一个 RESTful Flask 应用程序，其中 Angular 处理路由和视图逻辑，而 Flask 处理后端逻辑和资源。

问题：

当我启动 GAE 的开发服务器时，第一页加载完美。问题是，当我点击页面顶部的 Referrals link 时，正在加载的模板没有改变。

到目前为止我做了什么

虽然看起来我在下面粘贴了很多代码，但大部分都是标记，其中并没有任何复杂的应用程序逻辑，因此略读就足够了

我计划先构建前端，然后再构建后端（尽管我已经进行了一些后端设置）。该应用程序目前不依赖于烧瓶应用程序（它没有任何应用程序逻辑，也没有任何请求处理程序）

这是我的 app.js 文件，到目前为止我所做的只是路由，没有逻辑：

// app.js, only angular code in project and only does routing
var rcsApp = angular.module('rcsApp', [
    'ngRoute'
]);

rcsApp.config(['$routeProvider',
    function($routeProvider) {
        $routeProvider.
            when('/', {
                templateUrl: 'templates/welcome-page.html'
            }).
            when('/index', {
                templateUrl: 'templates/welcome-page.html'
            }).
            when('/referrals', {
                templateUrl: 'templates/referrals.html'
            }).
            when('/404', {
                templateUrl: 'templates/404.html'
            }).
            otherwise({
                redirectTo: '/404'
            });

}]);

这是我的 app.yaml 文件，这是我用来提供静态页面的文件

# This file specifies your Python application's runtime configuration
# including URL routing, versions, static file uploads, etc. See
# https://developers.google.com/appengine/docs/python/config/appconfig
# for details.

# TODO: Enter your application id below. If you have signed up
# using cloud.google.com/console use the "project id" for your application
# id.
application: placeholder
version: 1
runtime: python27
api_version: 1
threadsafe: yes

# Handlers define how to route requests to your application.
handlers:
# App Engine serves and caches static files contained in the listed directories
# (and subdirectories). Uncomment and set the directory as needed.
#- url: /client
#  static_dir: client

- url: /css
  static_dir: static/css

- url: /img
  static_dir: static/img

- url: /js
  static_dir: static/js

- url: /templates
  static_dir: templates

- url: /api/.*  
  script: main.app

- url: .*
  static_files: templates/app-view-wrapper.html
  upload: templates/app-view-wrapper.html

# Third party libraries that are included in the App Engine SDK must be listed
# here if you want to use them.  See
# https://developers.google.com/appengine/docs/python/tools/libraries27 for
# a list of libraries included in the SDK.  Third party libs that are *not* part
# of the App Engine SDK don't need to be listed here, instead add them to your
# project directory, either as a git submodule or as a plain subdirectory.
# TODO: List any other App Engine SDK libs you may need here.
#libraries:
#- name: jinja2
#  version: latest

这是整个应用程序的基础 html 模板：

以下是三个模板：

templates/welcome-page.html

<!-- templates/welcome-page.html -->
<div><h1>MAIN PAGE</h1></div>

templates/referrals.html

<!-- templates/referrals.html -->
<div><h1>REFERRALS PAGE</h1></div>

templates/404.html

<!-- templates/404.html -->
<div><h1>404</h1></div>

文件层次结构如下：

- rcsbackend
  - templates
  - static
    - img
    - js
    - css
  - app.yaml
  - main.py

Answer 1

您的解决方案成功了，因为默认情况下 html5mode 被禁用，这就是 angular 路由只识别 # 之后的 URL 的原因，并且你在 URL 为你工作之前设置了路线。

解决方案

您需要在应用程序中启用 html5mode 才能使路由正常工作，只需在 angular.

的配置阶段执行 $locationProvider.html5Mode(true)

代码

.config(function($locationProvider) {
    $locationProvider.html5Mode(true);
})

现在您可以返回到您的旧代码，将解决您的问题。

更新

为了 link 在您的应用程序周围使用相对 links，您需要在您的文档中设置一个。

<base href="/">

参考此 SO answer 可以帮助您在应用程序中启用 html5mode。
