How to get the GET request passed list data?

If I use the params for pass a list in GET method:

fetch_physicalserver_list(){

    var params = {
      id_list: this.physicalserver_id_list // there is [24, 26, 27]
    }

    this.$Lml_http('get', this.$Api_urls.user_productmanage_physicalserver.list(), params,  response => {
      this.physicalserver_list = response.data.results
      console.log( response.data.results)
    }, error => {

    })
}

And in the request, the id_list convert to the id_list[]=24&id_list[]=27&id_list[]=27.

enter image description here

and I don't know how to get the id_list in the backend.

I use the method to get the id_list[] I will only get the first id, if I get id_list, I will get nothing. enter image description here

the code of get_param_from_query_params method:

def get_param_from_query_params(query_params, param):

    param_temp = None

    try:
        mutable = query_params._mutable
        query_params._mutable = True

        param_list = query_params.pop(param)
        param_temp = param_list[0] if (isinstance(param_list, list) and len(param_list) > 0) else ''

        query_params._mutable = mutable
    except Exception as e:
        pass

    return param_temp

So, I have two questions:

1.The params's id_list converted to id_list[]. where is the official description? 2.How can I get the id_list after I passed to the backend?

Firstly, you are using the key id_list[], so you must use id_list[] to retrieve the key in Django. Including [] in JavaScript is a convention to show there are multiple values, but it makes no difference to Django.

If you want a list of values instead of a single value, then use pop_item instead of pop.

It's not clear to me why you need the get_param_from_query_params method. You are returning param_list[0] which means you'll only ever get a single item. It would be much simpler to use getlist:

id_list = query_params.getlist('id_list')
