将参数传递给AngularJS控制器方法

Question

This is probably a very basic question but I can't find the answer. 这可能是一个非常基本的问题，但我找不到答案。 I just started learning AngularJs and I am trying to do a simple page with a controller where you can enter a text in an input and make a HTTP GET request. 我刚开始学习AngularJs，我试图用控制器做一个简单的页面，您可以在输入中输入文本并发出HTTP GET请求。 So far I have the following: 到目前为止，我有以下内容：

In the HTML 在HTML中

<body ng-app="starter" ng-controller="searchController as searchController">

<ion-pane>
  <ion-header-bar class="bar-stable">
    <h1 class="title">Ionic Blank Starter</h1>
  </ion-header-bar>
  <ion-content>
    <input type="text" ng-model="searchController.searchString" required />
    <button class="btn" ng-click="searchController.search()">Search</button>
  </ion-content>
</ion-pane>

In the controller 在控制器中

angular.module('starter', [])
  .controller('searchController', function() {
    this.searchURL = 'http://www.myapifilms.com/imdb?title=%thetitle%&format=JSON';
    this.searchString = '';

    this.search = function searchMovie() {
        url = this.searchURL.replace('%thetitle%', this.searchString);
        console.log("URL: " + url);
        this.searchRequest($http, url);
    };

    this.searchRequest = function ($http, url) {
        $http.get(url).success(function(data) {
            console.log("Success: " + data);
        })
    };
});

The line this.searchRequest($http, url); 这行this.searchRequest($http, url); is obviously wrong because I have no reference to $http, which will be injected by AngularJs later. 显然是错误的，因为我没有引用$ http，稍后将由AngularJs注入。

So my question is how do I mix AngularJs services like $http with my own passed parameters? 所以我的问题是如何将像$ http这样的AngularJs服务与自己传递的参数混合使用？ Maybe I am not structuring this properly and would love to hear comments on that. 也许我没有适当地构建这个结构，希望听到对此的评论。 My goal is just to get input text and make a HTTP request with it. 我的目标只是获取输入文本并使用它发出HTTP请求。

Answer 1

you should inject service (angular or your custom service) in controller declaration instead of passing it in the method 您应该在控制器声明中注入服务（角度或自定义服务），而不是在方法中传递它

angular.module('starter', [])
    .controller('searchController', ["$http", function($http) {
        ...
    }]);
