django - 禁止(CSRF token 丢失或不正确。):

Question

我正在像下面这样进行ajax调用:

var data_dict = {'user':{{ user.id }}, 'bookId':that.id, 'csrfmiddlewaretoken': '{{ csrf_token }}'};
    $.ajax({
        type: 'POST',
        url:"/issuebook",
        data:data_dict,
        processData: false,
        contentType: false,
        success:function(response)
        {
        }
    });

urls.py是:

urlpatterns = [
url(r'^$',views.checkLogin,name='checklogin'),
url(r'^mylibrary/(?P<pk>\d+)/(?P<user_name>[\w\-]+)$',login_required(views.MyLibrary.as_view()),name='mylibrary'),
url(r'^centrallibrary/(?P<pk>\d+)/(?P<user_name>[\w\-]+)$',login_required(views.CentralLibrary.as_view()),name='centrallibrary'),
url(r'^issuebook$',login_required(views.IssueBookView.as_view()),name='issuebook'), 

]

我在ajax调用中收到“禁止(CSRF token 丢失或不正确。):/issuebook”错误。

Ajax调用中的csrf token 被呈现为:

var data_dict = {'user':{{ user.id }}, 'bookId':that.id, 'csrfmiddlewaretoken':'fSSdu8dJ4FO6FvDz8eU5ISzOewRYyGbC'};
                    $.ajax({
                        type: 'POST',
                        url:"/issuebook",
                        data:data_dict,
                        contentType: false,
                        success:function(response)
                        {
                        }
                    });

此错误是由ajax函数中的processData和contentType选项引起的。删除这两个选项将解决此问题。

说明:
参数必须以Content-Type application/x-www-form-urlencoded urlencode的形式发送到Django。而如果您设置processData: false，则不会对POST参数进行编码，并且contentType: false将ajax POST请求发送为text/plain。
