I want to transfer the array of objects to the background using post. This is how I pass it:

 Http({
            method:"POST",
            url:"addGroup",
            data:qs.stringify({
                "list":this.excelData
            })
 })

where excelData is an array of objects:

excelData:[{
    name:xxx,
    age;10
}{
    name:xxx,
    age;16
}] 

the background gets an empty set when reading list:

ci_list=request.POST.getlist("list")

ci_list=request.POST.getlist("list[]")

?
