我正在开发一个angularjs客户端，用于使用我在Django中编写的RESTful服务。我目前没有对服务进行任何开发，也不需要能够方便地进行更改。
我想方便地更改角度客户端。当我正在开发时，我希望通过127.0.0.1上的dockerized Nginx服务器或127.0.0.1:8000上的Django开发服务器运行服务，这两者都可以。默认情况下，grunt在127.0.0.1:9000上提供角度应用程序，这意味着调用我的服务，例如（coffeescript）：
return $resource('api/logos/:id')
正在寻找127.0.0.1:9000/api/…，它将无法找到。在开发过程中，如何剥离或更改角度正在寻找其服务的端口号？

更简单的方法是在服务上启用CORS。由于您的服务使用Django，您应该能够使用Django CORS headers app。
使用pip安装它，然后将corsheaders添加到已安装的应用程序中。接下来，在您的设置中添加Django常用中间件之前的CORS中间件，如下所示：
MIDDLEWARE_CLASSES = (
...
'corsheaders.middleware.CorsMiddleware',
'django.middleware.common.CommonMiddleware',
...
)
最后，再次在Django设置中将角度应用程序所在的端口列入白名单，如下所示：
CORS_ORIGIN_WHITELIST = (
'localhost:9000' # for example. Your port may vary.
)
在角度方面，您需要在开发过程中提供服务的完整路径，否则端口差异将导致问题。
我有一个类似的问题，这是我解决它的方式：
angular.module(...).config(['$httpProvider', function($httpProvider) {
$httpProvider.interceptors.push(['env', function(env) {
return {
'request': function(config) {
if( config.url.indexOf('/api/') === 0 ) {
config.url = env.apiContextPath + config.url;
}
return config;
}
};
}]);
}]);
你可能需要调整indexOf(...)部分，但你得到了一般的想法。阅读here关于拦截器。env服务保存应用程序环境配置，即它与本地开发，开发服务器，生产等不同。我使用grunt-ng-constant在Grunt中生成它，有很多方法可以做到 - 这里不详细介绍。grunt-connect才能使用代理。免责声明：我的配置略有不同，所以虽然一般的想法可能是正确的，但一些细节可能需要调整！
你需要grunt-connect-proxy。简而言之，请按照文档中的步骤操作：
将代理配置添加到connect:livereload
将代理中间件添加到您的中间件（我相信最好先）
livereload: {
options: {
open: false,
middleware: function (connect) {
return [
// ADDED PROXY MIDDLEWARE HERE
require('grunt-connect-proxy/lib/utils').proxyRequest,
connect.static('.tmp'),
connect().use(
'/bower_components',
connect.static('./bower_components')
),
connect().use(
'/app/styles',
connect.static('./app/styles')
),
connect.static(appConfig.app)
];
}
},
proxies: [{
context: '/api',
host: 'localhost', // the host serving your API
port: 8000 // again the port of your API server
}]
},
将configureProxy任务添加到服务器任务：
grunt.registerTask('serve', 'Compile then start a connect web server', function (target) {
if (target === 'dist') {
return grunt.task.run(['build', 'connect:dist:keepalive']);
}
grunt.task.run([
'clean:server',
'wiredep',
'concurrent:server',
'autoprefixer:server',
'configureProxies:livereload', // HERE
'connect:livereload',
'watch'
]);
});
