我收到以下错误：
错误： $injector：unpr 未知提供程序
未知提供程序：_planetsProvider <- _planets <- 搜索控制器
.API get 请求工作正常，我的 SearchController.js 也被触发，但我仍然收到上面的错误。我已经尝试了StackOverflow和官方文档中的几乎所有建议。我该如何解决它？
这是我的代码：(Plunker链接(
应用.js
var myApp = angular.module('myApp', ['ngRoute']);
myApp.config( function($routeProvider) {
$routeProvider
.when('/', { templateUrl: '/views/home.html',
controller: 'HomeController' })
.when('/login', { templateUrl: '/views/login.html',
controller: 'LoginController' })
.when('/search', { templateUrl: '/views/search.html',
controller: 'SearchController',
resolve:{
_planets: function(myService)
{
console.log("asdas");
return myService.getRequestForPlanets();
}
}
})
});
搜索控制器.js
angular.module('myApp').controller('SearchController', function($scope, myService, _planets, $rootScope) {
$scope.message = 'This is Show orders screen';
$scope.planets=_planets;
console.log(_planets);
});
我的服务.js
angular.module('myApp').service('myService', function($http, $rootScope, $location, $q)
{
$rootScope.loading = false;
this.getRequestForPlanets=function()
{
$rootScope.loading = true;
var deferred = $q.defer();
$http.get('https://swapi.co/api/planets')
.then(function(response){
$rootScope.loading = false;
console.log(response.data.results);
deferred.resolve(response.data.results);
})
.catch(function(response){
deferred.reject(response);
});
return deferred.promise;
}
});

基于您提供的 plnkr 链接：https://plnkr.co/edit/WRh3z5HTGby6nT1G8ovi?p=preview
您的控制器正在实例化两次，一次在您的路由中，app.js如下：
.when('/search', { templateUrl: '/views/search.html',
controller: 'SearchController',
...
再次以您在search.html这里的观点：
<div ng-controller="SearchController">
<p>{{message}}</p>
...
由于路由已将SearchController注入到应用中，因此第二次在视图中实例化时，会引发Unknown Provider错误。
如果您从search.html中删除ng-controller="SearchController"，它应该可以解决您遇到的问题。
希望对您有所帮助！
