如何在python中从JSON对象获取数据数组？

Question

I have a jquery POST function like this :

 $.post(data_send_url,
    {
        all_letters:["A","B","C"]
    },
    function(data, status){
        alert(data);
});

In the server side when I access it using request.data in a Django view function I get <QueryDict: {'all_letters[]': ['e', 'r', 'p']}> . How can I get a Python list like all_letters = ['e','r','p'] ?

Answer 1

This code solved my problem:

$.post(data_send_url,
    {
        all_letters:JSON.stringify(["A","B","C"]), //JSON.stringify added
    },
    function(data, status){
        alert(data);
});

And in views.py

json.loads(request.data.get("all_letters"))
json.loads(request.POST["all_letters"]) #both of these work fine

Answer 2

can you try to stringify the array and after this use json.loads ?

$.post(data_send_url,
    {
        all_letters: JSON.stringify(["A","B","C"])
    },
    function(data, status){
        alert(data);
});

# and after this use json.loads
import json

print(json.loads(request.data['all_letters']))

Answer 3

Try 'all_letter[]' as key just like below:

request.data["all_letters[]"]

This might work otherwise try to construct querydict properly in JS code and try to access it.
