如果你用$。Ajax函数，你可以简单地在数据体中添加CSRF令牌:

$.ajax({
    data: {
        somedata: 'somedata',
        moredata: 'moredata',
        csrfmiddlewaretoken: '{{ csrf_token }}'
    },

Non-jquery回答:

var csrfcookie = function() {
    var cookieValue = null,
        name = 'csrftoken';
    if (document.cookie && document.cookie !== '') {
        var cookies = document.cookie.split(';');
        for (var i = 0; i < cookies.length; i++) {
            var cookie = cookies[i].trim();
            if (cookie.substring(0, name.length + 1) == (name + '=')) {
                cookieValue = decodeURIComponent(cookie.substring(name.length + 1));
                break;
            }
        }
    }
    return cookieValue;
};

用法:

var request = new XMLHttpRequest();
request.open('POST', url, true);
request.setRequestHeader('Content-Type', 'application/x-www-form-urlencoded; charset=UTF-8');
request.setRequestHeader('X-CSRFToken', csrfcookie());
request.onload = callback;
request.send(data);

这个问题是因为django希望cookie中的值作为表单数据的一部分传递回来。前一个答案中的代码是让javascript寻找cookie值并将其放入表单数据中。从技术角度来看，这是一种可爱的方式，但它看起来有点啰嗦。

在过去，我通过让javascript将令牌值放入post数据中更简单地做到了这一点。

如果在模板中使用{% csrf_token %}，则会发出一个包含该值的隐藏表单字段。但是，如果你使用{{csrf_token}}，你只会得到令牌的裸值，所以你可以在javascript中使用这个....

csrf_token = "{{ csrf_token }}";

然后，可以在散列中包含所需的键名，然后将其作为数据提交给ajax调用。

我有一个解决办法。在我的JS我有两个函数。 首先得到饼干(即。csrftoken):

function getCookie(name) {
let cookieValue = null;
if (document.cookie && document.cookie !== '') {
    const cookies = document.cookie.split(';');
    for (let i = 0; i < cookies.length; i++) {
        const cookie = cookies[i].trim();
        // 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;

}

第二个是我的ajax函数。在这种情况下，它是用于登录的，实际上不返回任何东西，只是传递值来设置一个会话:

function LoginAjax() {


    //get scrftoken:
    const csrftoken = getCookie('csrftoken');

    var req = new XMLHttpRequest();
    var userName = document.getElementById("Login-Username");
    var password = document.getElementById("Login-Password");

    req.onreadystatechange = function () {
        if (this.readyState == 4 && this.status == 200) {            
            //read response loggedIn JSON show me if user logged in or not
            var respond = JSON.parse(this.responseText);            
            alert(respond.loggedIn);

        }
    }

    req.open("POST", "login", true);

    //following header set scrftoken to resolve problem
    req.setRequestHeader('X-CSRFToken', csrftoken);

    req.setRequestHeader("Content-type", "application/x-www-form-urlencoded");
    req.send("UserName=" + userName.value + "&Password=" + password.value);
}

将这一行添加到jQuery代码中:

$.ajaxSetup({
  data: {csrfmiddlewaretoken: '{{ csrf_token }}' },
});

和完成。

One CSRF token is assigned to every session ( i.e. every time you log in). So before you wish to get some data entered by user and send that as ajax call to some function which is protected by csrf_protect decorator, try to find the functions that are being called before you are getting this data from user. E.g. some template must be being rendered on which your user is entering data. That template is being rendered by some function. In this function you can get csrf token as follows: csrf = request.COOKIES['csrftoken'] Now pass this csrf value in context dictionary against which template in question is being rendered. Now in that template write this line: Now in your javascript function, before making ajax request, write this: var csrf = $('#csrf').val() this will pick value of token passed to template and store it in variable csrf. Now while making ajax call, in your post data, pass this value as well : "csrfmiddlewaretoken": csrf

这将工作，即使你没有实现django表单。

实际上，这里的逻辑是:您需要从请求中获得的令牌。 因此，您只需要在登录后立即找出被调用的函数。一旦你有了这个令牌，要么进行另一个ajax调用来获取它，要么将它传递给一些可以通过ajax访问的模板。
