在post请求上请求json时发生CSRF令牌错误

Question

我试图在django发出的post请求上呈现一个json响应，这样我的视图

from django.shortcuts import render
from django.http import HttpResponse
from django.views.generic import View

class TaskView(View):
    def get(self,request,*args,**kwargs):
        return HttpResponse("hello",content_type="application/json")
    def post(self,request,*args,**kwargs):
         return HttpResponse("hello",content_type="application/json")

这必须为get和post请求返回hello json响应。在

但我做了一个get请求，它正在工作。但如果我提出邮寄请求 我得到以下错误

^{pr2}$

我的中间件类设置

MIDDLEWARE_CLASSES = (
    'django.contrib.sessions.middleware.SessionMiddleware',
    'django.middleware.common.CommonMiddleware',
    'django.middleware.csrf.CsrfViewMiddleware',
    'django.contrib.auth.middleware.AuthenticationMiddleware',
    'django.contrib.auth.middleware.SessionAuthenticationMiddleware',
    'django.contrib.messages.middleware.MessageMiddleware',
    'django.middleware.clickjacking.XFrameOptionsMiddleware',
)

我需要重构视图的任何部分来处理json的post请求吗。在

Answer 1

如果您使用表单提交或ajax进行后调用。您需要在提交表单时传递{{csrf}}}。在

你能分享模板代码吗。。在

您需要在您的请求中实施明确的CSRF保护：

// using jQuery
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;
}
var csrftoken = getCookie('csrftoken');

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