django支持ajax的post方法

要在django框架下使用ajax的post方法，首先要在setting.py中做如下设置：

打开MIDDLEWARE_CLASSES 中的'django.middleware.csrf.CsrfViewMiddleware',

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

然后在要使用ajax的模版中做配置：

引入如下js（必须在引入jquery的js文件之后引入）：

                $('html').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;
            }
            if (!(/^http:.*/.test(settings.url) || /^https:.*/.test(settings.url))) {
                // Only send the token to relative URLs i.e. locally.
                xhr.setRequestHeader("X-CSRFToken", getCookie('csrftoken'));
            }
        });

然后就可以使用了·······
