6.1.优化json数据的返回

（1）新建utils/restful.py

# utils/restful.py

from flask import jsonify

class HttpCode(object):
    ok = 200
    unautherror = 401
    paramserror = 400
    servererror = 500

def restful_result(code,message,data):
    return jsonify({"code":code,"message":message,"data":data or {}})

def success(message="",data=None):
    return restful_result(code=HttpCode.ok,message=message,data=data)

def unauth_error(message=""):
    return restful_result(code=HttpCode.unautherror,message=message,data=None)

def params_error(message=""):
    return restful_result(code=HttpCode.paramserror,message=message,data=None)

def server_error(message=""):
    return restful_result(code=HttpCode.servererror,message=message or "服务器内部错误",data=None)

（2）cms/views.py

class ResetPwdView(views.MethodView):
    .
    .
    .
    .
            if user.check_password(oldpwd):
                user.password = newpwd
                db.session.commit()
                return restful.success()
            else:
                return restful.params_error("旧密码错误")
        else:
            return restful.params_error(form.get_error())

6.2.sweetalert优化修改密码结果反馈

（1）把sweetalert文件夹放到static/common下面

（2）在cms/cms_base.html中引用

  <link rel="stylesheet" href="{{ static("common/sweetalert/sweetalert.css") }}">
    <script src="{{ static("common/sweetalert/sweetalert.min.js") }}"></script>
    <script src="{{ static("common/sweetalert/zlalert.js") }}"></script>

（3）cms/js/resetpwd.js

/**
 * Created by derek on 2018/6/3.
 */

$(function () {
    $("#submit").click(function (event) {
        //阻止按钮的提交表单的事件
        event.preventDefault();
        //分别获取三个标签
        var oldpwdE = $("input[name=oldpwd]");
        var newpwdE = $("input[name=newpwd]");
        var newpwd2E = $("input[name=newpwd2]");

        var oldpwd = oldpwdE.val();
        var newpwd = newpwdE.val();
        var newpwd2 = newpwd2E.val();

        //1.要在模板的meta标签中渲染一个csrf-token
        //2.在ajax请求的头部汇总设置X-CSRFtoken
        zlajax.post({
            'url':'/cms/resetpwd',
            'data':{
                'oldpwd':oldpwd,
                'newpwd':newpwd,
                'newpwd2':newpwd2
            },
            'success':function (data) {
                if (data['code'] == 200){
                    zlalert.alertSuccessToast("恭喜!密码修改成功！");
                    oldpwd.val('');
                    newpwd.val('');
                    newpwd2.val('');
                }else {
                    var message = data['message'];
                    zlalert.alertInfo(message);
                }
            },
            'fail':function (error) {
                zlalert.alertNetworkError(error);
            }
        });
    });
});
