如何以角度扩展$ http服务？

Unfortunately, we're stuck running 1.2.26 (will upgrade to 1.2.28 when it's gemified).

不幸的是,我们遇到了1.2.26(当它被篡改时会升级到1.2.28)。

In the meantime, how can I patch (heh) $http so that the short-hand patch method is available? I'm pretty new to the whole service/factory/module thing. I've done hours of searching and can't seem to figure it out.

在此期间,我如何修补(heh)$ http以便可以使用短手补丁方法?我对整个服务/工厂/模块的事情都很陌生。我已经做了几个小时的搜索,似乎无法搞清楚。

myApp.factory('patchedHTTP', function($http, BasicService) {
  // $http['patch'] = function(url, data, config) {
  //   return $http(angular.extend(config || {}, {
  //     method: 'patch',
  //     url: url,
  //     data: data
  //   }));
  // };
  var extended = angular.extend(BasicService, {});
  extended.createShortMethodsWithData('patch');
  return extended;
});

Above is the best I've got... and it doesn't do anything XD

以上是我得到的最好的......它没有做任何XD

The module.decorator has been added to the module API in version 1.4. That's why it is not working in 1.2.x.

module.decorator已添加到1.4版的模块API中。这就是它在1.2.x中不起作用的原因。

Please find below a working demo or here at jsfiddle.

It took me a while to implement the patch method because I've missed to return the promise of $http. But now it should be working.

我花了一段时间来实现补丁方法,因为我错过了返回$ http的承诺。但现在它应该工作。

angular.module('patchDemo', [])
.config(function ($provide) {

    $provide.decorator('$http', function ($delegate) {
        // NOTE: $delegate is the original service
		$delegate.patch = function(url, data, config) {
            var paramsObj = angular.extend({}, config || {}, {
                method: 'PATCH',
                url: url,
                data: data
            });

            return $delegate(paramsObj);
        }
		
        return $delegate;
    });
})
.controller('MainController', MainController);

function MainController($http) {
    console.log($http.patch);
    //$http({method: 'PATCH', url: 'http://jsonplaceholder.typicode.com/posts/1', data: {title:'foo'}}); //>>>>>working long version of patch

    $http.patch('http://jsonplaceholder.typicode.com/posts/1', {
        title: 'foo'
    }).then(function(response) {
    	console.log(response);
    });

}

<div ng-app="patchDemo" ng-controller="MainController"></div>

You can do this with an angular decorator.

你可以用角度装饰器做到这一点。

A service decorator intercepts the creation of a service, allowing it to override or modify the behaviour of the service. The object returned by the decorator may be the original service, or a new service object which replaces or wraps and delegates to the original service. For more information you can check angular documentation.

服务装饰器拦截服务的创建,允许它覆盖或修改服务的行为。装饰器返回的对象可以是原始服务,也可以是替换或包装并委托给原始服务的新服务对象。有关更多信息,您可以检查角度文档。

Example:

var app = angular.module('app');
app.decorator('$http', function ($delegate) {
  // NOTE: $delegate is the original service

  $delegate.patch = function () {
    // do the implementation here
  };

  return $delegate;
});

// usage
app.controller('SomeController', function($http) {
    $http.patch();
});

You can keep this decorator until you upgrade to some newer version and than just safely delete it.

您可以保留此装饰器,直到升级到某个较新版本,而不是安全地删除它。
