如何在angularjs上的查询字符串中插入数据

app.controller('MyController', ['$scope', '$location', function($scope, $location) {
  // 控制器代码
}]);

var params = $location.search();

params.key = 'value';

$location.search(params);

app.controller('MyController', ['$scope', '$location', function($scope, $location) {
  var params = $location.search();
  params.key = 'value';
  $location.search(params);
}]);
