Hi there, I am quite new to Django and encounters a problem which
takes me a lot of time to figure out. As I known, Django provides some
functionality to prevent cross domain AJAX requests. However, using
jQuery you can specify a callback (JSONP) and could talk and get data
back from the server. For example:
$.getJSON('http://127.0.0.1:8000/biotool/prepDownload/login/?user=' +
uName + '&password=' + pWord + '&callback=?',
function (data) {
if (data != null) {
Load.displayPackages(data);
window.location = "#_sepa";
}
else {//request failed
var element =
document.getElementById("loginError");
element.innerHTML = "Could not authenticate
with server";
}
});
However, for some cases, when you need to send a large amount of data
to the server (in JSON format), you may have to use $.post(). This is
a sample section of code:
$.ajax( {
'url': 'http://127.0.0.1:8000/biotool/
prepDownload/test/',
'type': 'POST',
'data': {'rowID': '2', 'taxon': 'aaa'},
'success': function (s) {
alert (s);
} });
My views.py:
def test(request):
print request.POST
print request.GET
return HttpResponse('test')
The problem is the request.POST is empty. If I set the 'type' to GET:
the request.GET contains 2 elements which I sent as parameters. I have
searched the web for ages and did not find a solution to this problem.
I can solve the problem using GET, however, the data I sent may be
large and requires some kinds of structure. Please if anybody has
experience on this. There is a user with similar problems:

I have disabled all CSRF protections just to test this.
P/s: I have a log in page and some other pages using jQuery to
generate cross domain GET requests and they work fine. The problem
only arises when I use POST.
Thanks,
Viet Nguyen
