由于在url中追加params,控制器被调用两次

Question

我在angularjs.我试图在url中添加参数$location.search('sid', key);.key的值来自另一个服务器的http请求.这是append参数的代码.

.config(['$routeProvider',function ($routeProvider) {
        $routeProvider
            .when('/', {
                templateUrl: 'test1.html',
                controller: 'test1Controller'
            })
            .when('/message/:userId', {
                templateUrl: 'test2.html',
                controller: 'test2Controller'
            })
            .otherwise({
                redirectTo: '/'
            });
    }])
.run(['$route', '$rootScope', '$location' ,'getAuthDetails', function($route, $rootScope, $location,getAuthDetails) {
        var key;

        getAuthDetails.get().then(function(data){
            key = data.key;
            $rootScope.query = 'sid='+key;
            console.log($location.$$path);
            $location.search('sid', key);  //append parameter. This is calling controller twice
        });

        $rootScope.$on('$routeChangeSuccess', function () {
            $rootScope.query = 'sid='+key;
        });
    }]);

我遇到的问题是.随着sid被添加到url中.该console.log放我test1Controller越来越调用两次.Sid用于连接套接字连接.

是否有任何解决方法在url追加后调用控制器.

您可以使用 reloadOnSearch: false

例:

.config(['$routeProvider',function ($routeProvider) {
        $routeProvider
            .when('/', {
                templateUrl: 'test1.html',
                controller: 'test1Controller',
                reloadOnSearch: false // wont reload the controller when the search query changes
            })
            .when('/message/:userId', {
                templateUrl: 'test2.html',
                controller: 'test2Controller'
            })
            .otherwise({
                redirectTo: '/'
            });
    }])
