【laravel5.4】中jquery的post Ajax提交

1、post的ajax需要提交csrf_token字段，進行安全過濾

<meta name="csrf-token" content="{{ csrf_token() }}">
/* ajax回填表單字段,然后提交表單 */
                $.ajax({
                    headers: {
                        'X-CSRF-TOKEN': $('meta[name="csrf-token"]').attr('content')
                    },
                    type: 'POST',
                    url: '/ddoa/***',
                    data: {event:'crm_user',ding_name:ding_name,ding_userid:ding_userid,ding_openId:ding_openId},
                    dataType: 'json',
                    async : 'false',    //同步
                    success: function(data){
                        logger.i(data);
                        console.log(data);
                        if(data.code==1){
                            $("input[name='username']").val(data.username);
                            $("input[name='password']").val('123456');
                            $("#loginForm").submit();
                        }
                       },
                       error:function(data){
                        console.log(data);
                       }
                });
