ajax导致csrf验证失败的解决方法

开发十年，就只剩下这套Java开发体系了 >>>   

解决方法如下:

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;
}


$("#save").on("click",function({
	var csrftoken = getCookie('csrftoken');
	$.ajax({
		url:"{{ url 'login' }}",
		type:"post",
		data:{"id": result_id, "action": "get_result", "csrfmiddlewaretoken":getCookie('csrftoken')},
	})	
}))
