首先在from表单中加上

{% csrf_token %} 如果还出现

　　POST http://127.0.0.1:8000/login/ 403 (Forbidden)

　　send @ jquery.min.js:6

　　ajax @ jquery.min.js:6

　　(anonymous) @ (index):37

　　dispatch @ jquery.min.js:5

　　y.handle @ jquery.min.js:5

 

-----------------解决方法-----------------

在JS文件中加入

$(document).ajaxSend(function(event, xhr, settings) {    function getCookie(name) {        var cookieValue = null;        if (document.cookie && document.cookie != '') {            var cookies = document.cookie.split(';');            for (var i = 0; i < cookies.length; i++) {                var cookie = jQuery.trim(cookies[i]);                // Does this cookie string begin with the name we want?                if (cookie.substring(0, name.length + 1) == (name + '=')) {                    cookieValue = decodeURIComponent(cookie.substring(name.length + 1));                    break;                }            }        }        return cookieValue;    }    function sameOrigin(url) {        // url could be relative or scheme relative or absolute        var host = document.location.host; // host + port        var protocol = document.location.protocol;        var sr_origin = '//' + host;        var origin = protocol + sr_origin;        // Allow absolute or scheme relative URLs to same origin        return (url == origin || url.slice(0, origin.length + 1) == origin + '/') ||            (url == sr_origin || url.slice(0, sr_origin.length + 1) == sr_origin + '/') ||            // or any other URL that isn't scheme relative or absolute i.e relative.            !(/^(\/\/|http:|https:).*/.test(url));    }    function safeMethod(method) {        return (/^(GET|HEAD|OPTIONS|TRACE)$/.test(method));    }    if (!safeMethod(settings.type) && sameOrigin(settings.url)) {        xhr.setRequestHeader("X-CSRFToken", getCookie('csrftoken'));    }});
