javascript - 如何从 Angularjs 中的选择选项生成的动态 url 中删除双引号？

Question

我想创建 url，它将从服务器获取 json 数据。我能够生成动态网址，但它包含双引号http://localhost/admin/metering/samples?meter="instance"&group_by="project"&stats_attr="avg"&date_options=7&date_from=&date_to=

请参阅上面的网址，它包含双引号中的“实例”，但它不应该是这样的，
正确的网址是 http://192.168.206.133:8080/admin/metering/samples?meter=instance&group_by=project&stats_attr=avg&date_options=7&date_from=&date_to=

注意:如果您知道生成动态网址的好方法，那么您可以告诉我。

Angularjs

 $http.get("data.json")
    .success(function(response) {
      $scope.metrics = response.nova_meters.concat(response.glance_meters);

      $scope.metric = $scope.metrics[0];         
       $scope.groups=[{"name": "project", "value":"project" ,"label": "project"}];
      $scope.group_by = $scope.groups[0];  
       $scope.stats_attrs=[
      {
            "name": "avg", 
            "value": "avg",         
            "label": "avg"            
      },
      {
            "name": "min",
            "value": "min",          
            "label": "min"            
      },
      {
            "name": "max", 
            "value": "max",         
            "label": "max"            
      },
      {
            "name": "sum", 
            "value": "sum",         
            "label": "sum"            
      }
   ];

      $scope.stats_attr = $scope.stats_attrs[0];         
      $scope.date_options = [{
        "value": 1,
        "label": "Last day"
      }, {
        "value": 7,
        "label": "Last week"
      }, {
        "value": 23,
        "label": "Month to date"
      }, {
        "value": 30,
        "label": "Last 30 days"
      }, {
        "value": 356,
        "label": "Last year"
      }, {
        "value": "Other",
        "label": "Other"
      }];

      $scope.date_option = $scope.date_options[1];          
      var url="http://192.168.206.133:8080/admin/metering/samples?"+"meter="+JSON.stringify($scope.metric.label)+"&group_by="+JSON.stringify($scope.group_by.label)+"&stats_attr="+JSON.stringify($scope.stats_attr.label)+"&date_options="+JSON.stringify($scope.date_option.value)+"&date_from=&date_to=";

    });

从 URL 中删除 JSON.stringify

var url="http://192.168.206.133:8080/admin/metering/samples?"+"meter="+$scope.metric.label+"&group_by="+$scope.group_by.label+"&stats_attr="+$scope.stats_attr.label+"&date_options="+$scope.date_option.value+"&date_from=&date_to=";
