django 使用post方法出现403错误的解决办法

当采用客户端象django的服务器提交post请求时。会得到403，权限异常。因为django针对提交的请教，有校验。所以会如此。

解决办法：

导入模块：from django.views.decorators.csrf import csrf_exempt

在接收post请求的函数前面添加修饰器：@csrf_exempt

 //用户必须登陆这个getCookie才会起作用 

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;
}

     //用户必须登陆这个getCookie才会起作用  
     var csrftoken = getCookie('csrftoken');
       $.ajax({
            cache: false,
            type: "POST",
            url: "/showtable/",
            traditional:true,  //加上此项可以传数组
            dataType:'json',
            async: true,
            data:{'l1_first':l1_first},
            success: function(data) {
                console.log(data);

                $('#show_tree_table').bootstrapTable('destroy');
                //显示表头 并且导入数据
                show_list_table(data.table_title_list,data.new_project_json);
                $('body').mLoading("hide");
                totalpage = data.totalpage;
                console.log(totalpage);

               //进行分页
               $("#pagination2").pagination({
                   currentPage: 1,
                   totalPage: Math.ceil(totalpage / 20),
                   callback: function(current) {
                       PageNation(current);
                   }

               })


            },
            beforeSend: function(xhr, settings) {
                xhr.setRequestHeader("X-CSRFToken", csrftoken);
            }

       });
