为什么它在location.hash中附加＃/ ...

Question

我正在为我的应用使用角度js。

在这里，My Angular代码为：

var app = angular.module('TaskManager', ['ngCookies']);

app.controller('LoginController', function($scope, $http, $location, $cookieStore) {

  $scope.login = function(str) {
    console.log(".......... login called......");

       $http({
        method: 'POST',
        url: '../TaskManager/public/user/login',
        data: $.param({
          email: email.value,
          password: password.value
        }),
        headers: {
          'Content-Type': 'application/x-www-form-urlencoded'
        }
      })
        .success(function(data, status) {
        console.log(data);
        var result = data.response;
        console.log(result);

        if (result == "success") {          

          //storing value at cookieStore
          $cookieStore.put("loggedin", "true");
          $cookieStore.put("loggedUserId", data.user_id);
          $cookieStore.put("password", data.password);
          $cookieStore.put("type", data.type);
          $cookieStore.put("email", data.email);             

          location.href='Dashboard.html';                      

        } else alert(data.message);
      });         
});   


app.controller('DashboardController', function($scope, $http, $location, $cookieStore) {    

  $scope.users = [];    

  $http({
    method: 'POST',
    url: '../TaskManager/public/task/tasklist',
    data: $.param({
      logged_userid: userId,
      password: password,
      status: 'All',
      user_id: useridToFetch
    }),
    headers: {
      'Content-Type': 'application/x-www-form-urlencoded'
    }
  })
    .success(function(data, status) {
    console.log(data);
    $scope.users = data.users;

  });       

  //location.hash="";    
  console.log(window.location);
});

它工作正常，但在登录后重定向到仪表板页面时，location.hash正在分配#/PAGE_NAME。它变为location.hash=#/PAGE_NAME，导致URL值重复。

像：

http://localhost:8085/NovaTaskManager/Dashboard.html#/Dashboard.html

我试图在DashboardController上清除哈希值，这会清除一段时间但刷新页面后会再次显示早期的URL。

不知道：

   1. why location.hash is getting assigned by default ?
   2. How it can be resolved ?

任何建议都将不胜感激。
