Javascript Csrf验证失败-Django Rest和Backbone.js

我已经开始学习“轻量级Django”，以进一步了解Django和客户端JavaScript。在测试使用

Backbone.js创建的
LoginView
期间，我得到了
禁止（403）CSRF验证失败。请求中止。
消息，如本文所述：。
首先，我想在表单中插入
{%csrf\u token%}
模板标记，但当我这样做时，服务器会给我一条
POST/HTTP/1.1“405 0-不允许使用方法（POST）：/
消息

由于AJAX
X-CSRFToken
请求头是使用
$.ajaxPrefilter（）
设置的，因此我无法找出问题所在

当我使用httpie使用超级用户详细信息执行POST请求时，一切正常，如下例所示：

 HTTP/1.0 200 OK
 Allow: POST, OPTIONS
 Content-Type: application/json
 Date: Mon, 11 Sep 2017 13:49:49 GMT
 Server: WSGIServer/0.2 CPython/3.6.2
 Vary: Cookie
 X-Frame-Options: SAMEORIGIN

 {
    "token" : some_value
 }

利用控制台的“Inspect Element”功能，我得到以下消息：

 Response headers:
   Allow: GET, HEAD, OPTIONS
   Content-Length: 0
   Content-Type: text/html; charset=utf-8
   Date: Mon, 11 Sep 2017 14:03:06 GMT
   Server: WSGIServer/0.2 CPython/3.6.2
   X-Frame-Options: SAMEORIGIN

 Request headers:
   Accept: text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8
   Accept-Encoding: gzip, deflate
   Accept-Language: en-US,en;q=0.5
   Connection: keep-alive
   Content-Length: 116
   Content-Type: application/x-www-form-urlencoded
   Cookie: csrftoken=some_value
   Host: 127.0.0.1:8000
   Referer: http://127.0.0.1:8000/
   Upgrade-Insecure-Requests: 1
   User-Agent: Mozilla/5.0 (X11; Ubuntu; Linux x86_64; rv:55.0) Gecko/20100101 Firefox/55.0

我不知道是因为
模板视图
还是我遗漏了什么：

 urls.py:    
   from django.conf.urls import url,include
   from django.views.generic import TemplateView
   #from django.views.decorators.csrf import ensure_csrf_cookie

   from rest_framework.authtoken.views import obtain_auth_token

   from board.urls import router

   urlpatterns = [
       url(r'^api-auth/', obtain_auth_token, name='api-login'),
       url(r'^api-root/', include(router.urls)),
       url(r'^$', TemplateView.as_view(template_name='board/index.html')),
   ]

有人能解释一下到底发生了什么吗？
谢谢！
在每个POST请求之前，您需要将CSRF令牌发送到django weebasite中的django后端，您可以为您的前端（backbone.js）创建一个ajaxSetup。只需创建新文件ajaxSetup.js并通过此代码即可

function csrfSafeMethod(method) {
    // these HTTP methods do not require CSRF protection
    return (/^(GET|HEAD|OPTIONS|TRACE)$/.test(method));
}
function sameOrigin(url) {
    // test that a given url is a same-origin URL
    // url could be relative or scheme relative or absolute
    var host = document.location.host; // host + port
    var protocol = document.location.protocol;
    var sr_origin = '//' + host;
    var origin = protocol + sr_origin;
    // Allow absolute or scheme relative URLs to same origin
    return (url == origin || url.slice(0, origin.length + 1) == origin + 
    '/') ||
    (url == sr_origin || url.slice(0, sr_origin.length + 1) == sr_origin + 
    '/') ||
    // or any other URL that isn't scheme relative or absolute i.e relative.
    !(/^(\/\/|http:|https:).*/.test(url));
}
$.ajaxSetup({
    beforeSend: function(xhr, settings) {
        if (!csrfSafeMethod(settings.type) && sameOrigin(settings.url)) {
            // Send the token to same-origin, relative URLs only.
            // Send the token only if the method warrants CSRF protection
            // Using the CSRFToken value acquired earlier
            xhr.setRequestHeader("X-CSRFToken", csrftoken);
        }
    }
});
