jQuery最常用的发送ajax方式

 $('#add_submit_ajax').click(function(){
                $.ajax({
                    url: '/ajax_add_app',
                    // data: {'user': 123,'host_list': [1,2,3,4]},
                    data: $('#add_form').serialize(),
                    type: "POST",
                    dataType: 'JSON', // 内部  让jQuery把返回的 json字符串 转成json对象 
                    traditional: true,  //当发送的数据有列表时 告诉jQuery你不要帮我处理 直接发过去
                    success: function(obj){
                        console.log(obj);
                    },
                    error: function () {

                    }

                })
            });

二：

<script src="/static/jquery-1.12.4.js"></script>
    <script src="/static/jquery.cookie.js"></script>
    <script>
        $(function(){
            $.ajaxSetup({ // 发送ajax前 进行统一设置
                beforeSend: function(xhr,settings){ // xhr 是XMLHttpRequest  原生的发ajax请求对象
                    xhr.setRequestHeader('X-CSRFtoken', $.cookie('csrftoken')); //设置请求头
                }
            });

            $('#btn1').click(function () {
                $.ajax({
                    url: '/login/',
                    type:"GET",
                    data: {'user': 'root', 'pwd': '123'},
                    // headers: {'X-CSRFtoken': $.cookie('csrftoken')},
                    success:function(arg){

                    }
                })
            });
        })
    </script>

django中

views

from django.template.context import RequestContext
# Create your views here.
  
  
def test(request):
  
    if request.method == 'POST':
        print request.POST
        return HttpResponse('ok')
    return  render_to_response('app01/test.html',context_instance=RequestContext(request))

        $.ajaxSetup({

                if (!csrfSafeMethod(settings.type) && !this.crossDomain) {
                    xhr.setRequestHeader("X-CSRFToken", csrftoken);
                }
