我有一个非常简单的资源像这样我的模式“PRESENTACION”
class PresentacionResource(ModelResource):
model = Presentacion
fields = (some fields)
ignore_fields = (few to ignore)
我需要实现这种验证,所以只要我阅读,我创建了两个包装
class AuthListOrCreateModelView(ListOrCreateModelView):
permissions = (IsAuthenticated, )
class AuthInstanceModelView(InstanceModelView):
permissions = (IsAuthenticated, )
然后我在我的urls.py
url(r'^presentaciones/$', AuthListOrCreateModelView.as_view(resource=PresentacionResource), name='presentacion-root'),
url(r'^presentaciones/(?P<id>[0-9]+)$', AuthInstanceModelView.as_view(resource=PresentacionResource), name='presentacion'),
这是get做工精细“presentaciones /的要求,但是当我尝试做一个PUT请求,我越来越不允许的403
什么是奇怪,我是GET是工作的罚款:只要我登录,它的正确响应,但如果我退出它与403 FORBIDDEN响应。
如果您正在使用Django的基于会话的认证,那么你可能会绊倒建成的Django的CSRF保护(见UserLoggedInAuthentication类[1])。
如果是这样的话,你需要确保CSRF的cookie被发送到客户端,然后你可以适应jQuery的指令[2]与可能更改数据请求发送X-CSRFToken头。
[1] http://django-rest-framework.org/_modules/authentication.html
[2] https://docs.djangoproject.com/en/dev/ref/contrib/csrf/#ajax
如果问题是X-CSRF令牌头可以修改Backbone.sync这样发送令牌,每个POST,PUT,DELETE请求。
/* alias away the sync method */
Backbone._sync = Backbone.sync;
/* define a new sync method */
Backbone.sync = function(method, model, options) {
/* only need a token for non-get requests */
if (method == 'create' || method == 'update' || method == 'delete') {
// CSRF token value is in an embedded meta tag
var csrfToken = $("meta[name='csrf_token']").attr('content');
options.beforeSend = function(xhr){
xhr.setRequestHeader('X-CSRFToken', csrfToken);
};
}
/* proxy the call to the old sync method */
return Backbone._sync(method, model, options);
};
我意识到这是一个较旧的职位,但最近我处理这个问题。 扩大对@ orangewarp的回答,并使用Django文档( https://docs.djangoproject.com/en/dev/ref/contrib/csrf/#ajax ),这里有一个解决方案:
该解决方案采用了csrftoken饼干。 另一种解决方案是创建你的API在CSRF令牌端点,并从那里抢CSRF。
Backbone._sync = Backbone.sync;
Backbone.sync = function(method, model, options) {
//from django docs
function getCookie(name) {
var cookieValue = null;
if (document.cookie && document.cookie != '') {
var cookies = document.cookie.split(';');
for (var i = 0; i < cookies.length; i++) {
var cookie = jQuery.trim(cookies[i]);
// Does this cookie string begin with the name we want?
if (cookie.substring(0, name.length + 1) == (name + '=')) {
cookieValue = decodeURIComponent(cookie.substring(name.length + 1));
break;
}
}
}
return cookieValue;
}
/* only need a token for non-get requests */
if (method == 'create' || method == 'update' || method == 'delete') {
var csrfToken = getCookie('csrftoken');
options.beforeSend = function(xhr){
xhr.setRequestHeader('X-CSRFToken', csrfToken);
};
}
return Backbone._sync(method, model, options);
};
