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'));

}

});
