python - Ajax post请求返回空querydict

Question

我正在尝试发送一个发布请求并根据该信息对用户进行身份验证。然而，即使我已经检查了 $('#sign_in').serialize() 的结果它返回类似 username=test&password=test 的内容它仍然返回 <QueryDict: {}>当我跑print(request.POST)时在我的views.py里面。我做错了什么以及为什么它不传递参数？

ajax函数

function logIn() {
    var username = $('#id_username').val();
    var password = $('#id_password').val();
    console.log($('#sign_in').serialize())
    $('#sign_in_btn').text('Logger ind...');
    $.ajax({
        url: "/account/login/",
        type: "POST",
        dataType: 'json',
        contentType: 'application/json',
        data: $('#sign_in').serialize(),
        success: function (data) {
            console.log(data)

        }, error: function (error) {

        }
    });
}

views.py

def login(request):
    print(request.POST)
    if request.method == "POST":
        form = SignInForm(data=request.POST)
        response_data = {}
        if form.is_valid():
            username = request.POST.get("username", False)
            password = request.POST.get("password", False)
            user = authenticate(username=username, password=password)
            auth_login(request, user)
            if user:
                response_data['success'] = True
                response_data['message'] = 'Brugeren er blevet oprettet!'
        else: #invalid case
            response_data['success'] = False
            response_data['message'] = 'Forkert brugernavn/kodeord. Prøv venligst en anden kombination eller tryk på glemt kodeord!'
            print(form.errors)
        return HttpResponse(json.dumps(response_data), content_type='application/json')
    else:
        form = SignInForm()
    return render(request, 'login.html', {'form': form})

您需要将 contentType 更改为 application/x-www-form-urlencoded 或将其留空，因为其默认值为application/x-www-form-urlencoded;charset=UTF-8。

The thing is .serialize() returns the content of the form URL-encoded not as JSON.
