12ABPZero系列教程之拼多多卖家工具 拼团提醒功能登录拼多多实现

Posted 2020-10-21 shensigzs

　　上篇文章已经完成了整个拼多多拼团提醒功能，本篇继续完成拼多多帐号登录，拼多多帐号登录的目的是为了获取拼团商品的SKU和订单号，便于商家备货。

以下是拼多多官方的后台登录，要实现的功能并不是直接在这里登录，而是在项目通过发送数据包的方式去登录，主要就是拿到登录后的cookie或token。

注：做此功能需要准备拼多多卖家帐号，如果没有，可以跳过本篇内容。

 

PddTool项目

添加CodeResponse.cs文件，代码如下：

文件路径：D:\\abp version\\aspnet-zero-3.4.0\\aspnet-zero-3.4.0\\src\\PddTool\\PddApi\\Response\\CodeResponse.cs

public class CodeResponse
    {
        /// <summary>
        /// 
        /// </summary>
        public bool result { get; set; }
        /// <summary>
        /// 
        /// </summary>
        public Data data { get; set; }
    }
    public class Data
    {
        /// <summary>
        /// 
        /// </summary>
        public string token { get; set; }
        /// <summary>
        /// 
        /// </summary>
        public string image { get; set; }
    }

 

 

添加UserResponse.cs文件，代码如下：

文件路径：D:\\abp version\\aspnet-zero-3.4.0\\aspnet-zero-3.4.0\\src\\PddTool\\PddApi\\Response\\UserResponse.cs

/// <summary>
    /// 登录返回
    /// </summary>
    public class UserResponse
    {
        /// <summary>
        /// 
        /// </summary>
        public bool authResult { get; set; }
        /// <summary>
        /// 
        /// </summary>
        public UserInfo userInfo { get; set; }
        /// <summary>
        /// 
        /// </summary>
        public string inMobileWhiteList { get; set; }
        /// <summary>
        /// 
        /// </summary>
        public string mobileVerification { get; set; }
    }
    public class UserInfo
    {
        /// <summary>
        /// 用户id
        /// </summary>
        public int id { get; set; }
        /// <summary>
        /// 用户名
        /// </summary>
        public string username { get; set; }
        /// <summary>
        /// 店铺id
        /// </summary>
        public int mallId { get; set; }
        /// <summary>

        public int passwordStatus { get; set; }
        /// <summary>
        /// 手机
        /// </summary>
        public string mobile { get; set; }

        public string nickname { get; set; }
        /// <summary>
        /// 角色id列表
        /// </summary>
        public List<int> roleIdList { get; set; }
        /// <summary>

        /// <summary>
        /// 
        /// </summary>
        public List<string> roleNameList { get; set; }
        /// <summary>

        /// <summary>
        /// 登录cookie
        /// </summary>
        public string Cookie { get; set; }
    }

 

 

添加RequestErrorResponse.cs文件，代码如下：

文件路径：D:\\abp version\\aspnet-zero-3.4.0\\aspnet-zero-3.4.0\\src\\PddTool\\PddApi\\Response\\RequestErrorResponse.cs

/// <summary>
    /// 请求错误返回
    /// </summary>
    public class RequestErrorResponse
    {
        /// <summary>
        /// 
        /// </summary>
        public string error_msg { get; set; }
        /// <summary>
        /// 
        /// </summary>
        public int error_code { get; set; }
    }

 

 

添加LoginRequest.cs文件，代码如下：

文件路径：D:\\abp version\\aspnet-zero-3.4.0\\aspnet-zero-3.4.0\\src\\PddTool\\PddApi\\Request\\LoginRequest.cs

        /// <summary>
        /// 令牌
        /// </summary>
        public string Token { get; set; }
    }

 

 

修改MallTool.cs文件，末尾添加如下代码：

文件路径：D:\\abp version\\aspnet-zero-3.4.0\\aspnet-zero-3.4.0\\src\\PddTool\\MallTool.cs

/// <summary>
        /// 取验证码
        /// </summary>
        /// <returns></returns>
        public static CodeResponse GetCode()
        {
            string url = string.Format("http://mms.pinduoduo.com/captchaCode/getCaptchaCode?rd=" + Guid.NewGuid());
            var client = new RestClient(url);
            var request = new RestRequest(Method.GET);
            request.AddHeader("cache-control", "no-cache");
            request.AddHeader("referer", "http://mms.pinduoduo.com/Pdd.html");
            IRestResponse response = client.Execute(request);
            var code = JsonConvert.DeserializeObject<CodeResponse>(response.Content);
            return code;
        }

        /// <summary>
        /// 拼多多登录
        /// </summary>
        /// <param name="data"></param>
        /// <returns></returns>
        public static UserResponse Login(LoginRequest data)
        {
            string url = "http://mms.pinduoduo.com/auth";
            var client = new RestClient(url);
            var request = new RestRequest(Method.POST);
            request.AddParameter("username", data.Username);
            request.AddParameter("password", data.Password);
            request.AddParameter("authCode", data.Code);
            request.AddParameter("verificationCode", "");
            request.AddParameter("token", data.Token);
            request.AddHeader("cache-control", "no-cache");
            IRestResponse response = client.Execute(request);
            if (response.Content.Contains("error_code"))
            {
                var error = JsonConvert.DeserializeObject<RequestErrorResponse>(response.Content);
                throw new UserFriendlyException(error.error_msg);
            }
            var c = response.Cookies.Single(a => a.Name.Equals("PASS_ID"));
            var cookie = c.Value;
            var user = JsonConvert.DeserializeObject<UserResponse>(response.Content);
            user.userInfo.Cookie = cookie;
            return user;
        }

 

到这里就把拼多多后台登录封装好了，就2个方法，一个获取验证码、一个提交post数据登录。

 

Application项目

修改IMallAppService.cs文件，添加2个方法，代码如下：

文件路径：D:\\abp version\\aspnet-zero-3.4.0\\aspnet-zero-3.4.0\\src\\MyCompanyName.AbpZeroTemplate.Application\\Pdd\\MallApp\\IMallAppService.cs

/// <summary>
        /// 取验证码
        /// </summary>
        /// <returns></returns>
        CodeOutput GetCode();

        /// <summary>
        /// 登录
        /// </summary>
        /// <returns></returns>
        UserInfoOutput Login(LoginInput input);

 

 

添加CodeOutput.cs文件，代码如下：

public class CodeOutput
    {
        /// <summary>
        /// 图片
        /// </summary>
        public string Image { get; set; }

        /// <summary>
        /// 令牌

public class UserInfoOutput
    {
        /// <summary>
        /// 用户名
        /// </summary>
        public string Username { get; set; }

        /// <summary>
        /// 店铺id
        /// </summary>
        public int MallId { get; set; }

        /// <summary>
        /// 
        /// </summary>
        public string Cookie { get; set; }
    }

 

 

添加LoginInput.cs文件，代码如下：

文件路径：D:\\abp version\\aspnet-zero-3.4.0\\aspnet-zero-3.4.0\\src\\MyCompanyName.AbpZeroTemplate.Application\\Pdd\\MallApp\\Dto\\LoginInput.cs

public class LoginInput
    {
        /// <summary>
        /// 用户名
        /// </summary>
        public string Username { get; set; }

        /// <summary>
        /// 密码
        /// </summary>
        public string Password { get; set; }

        /// <summary>
        /// 验证码
        /// </summary>
        public string Code { get; set; }

        /// <summary>
        /// 令牌
        /// </summary>
        public string Token { get; set; }
    }

 

 

修改MallAppService.cs文件，实现接口添加的2个方法，代码如下：

文件路径：D:\\abp version\\aspnet-zero-3.4.0\\aspnet-zero-3.4.0\\src\\MyCompanyName.AbpZeroTemplate.Application\\Pdd\\MallApp\\MallAppService.cs

 /// <summary>
        /// 获取验证码
        /// </summary>
        /// <returns></returns>
        public CodeOutput GetCode()
        {
            var code = MallTool.GetCode();
            if (code.result == false)
            {
                throw new UserFriendlyException("验证码获取失败！");
            }
            return new CodeOutput()
            {
                Image = code.data.image,
                Token = code.data.token
            };
        }

        /// <summary>
        /// 登录
        /// </summary>
        /// <returns></returns>
        public UserInfoOutput Login(LoginInput input)
        {
            var data = Mapper.Map<LoginRequest>(input);
            try
            {
                var key = string.Format("{0}_{1}_Mall", AbpSession.UserId, input.Username);
                var cache = _cacheManager.GetCache<string, UserResponse>(key);
                if (cache != null)
                {
                    cache.Clear();
                }
                var user = _cacheManager.GetCache<string, UserResponse>(key).Get("Login." + input.Username, () => MallTool.Login(data));
                //登录成功清除对应店铺开团商品的缓存
                key = string.Format("{0}_{1}_KaiTuan", AbpSession.UserId, user.userInfo.mallId);
                _cacheManager.GetCache<string, List<KaiTuan>>(key).Clear();

                return new UserInfoOutput()
                {
                    Cookie = user.userInfo.Cookie,
                    MallId = user.userInfo.mallId,
                    Username = input.Username
                };
            }
            catch (Exception ex)
            {
                throw new UserFriendlyException("登录失败：" + ex.Message);
            }

        }

 

 

打开CustomDtoMapper.cs文件，添加如下映射：

文件路径：D:\\abp version\\aspnet-zero-3.4.0\\aspnet-zero-3.4.0\\src\\MyCompanyName.AbpZeroTemplate.Application\\CustomDtoMapper.cs

mapper.CreateMap<LoginInput, LoginRequest>();

 

 

生成解决方案，浏览器打开http://localhost:8088/swagger/ui/index，测试刚刚添加的2个api。

接下来页面实现。

 

打开KaiTuanController.cs文件，添加如下代码：

文件路径：D:\\abp version\\aspnet-zero-3.4.0\\aspnet-zero-3.4.0\\src\\MyCompanyName.AbpZeroTemplate.Web\\Areas\\Mpa\\Controllers\\Pdd\\KaiTuanController.cs

public ActionResult LoginModal()
        {
            var code = _mallAppService.GetCode();
            ViewBag.code = code;
            return PartialView("_LoginModal");
        }

 

 

添加对应的视图文件_LoginModal.cshtml，代码如下：

文件路径：D:\\abp version\\aspnet-zero-3.4.0\\aspnet-zero-3.4.0\\src\\MyCompanyName.AbpZeroTemplate.Web\\Areas\\Mpa\\Views\\KaiTuan\\_LoginModal.cshtml

@using MyCompanyName.AbpZeroTemplate.Pdd.MallApp.Dto
@using MyCompanyName.AbpZeroTemplate.Web.Areas.Mpa.Models.Common.Modals
@{
    var code = ViewBag.code as CodeOutput;
}
@Html.Partial("~/Areas/Mpa/Views/Common/Modals/_ModalHeader.cshtml", new ModalHeaderViewModel("登录拼多多"))
<div class="modal-body">
    <form name="LoginForm" class="form-horizontal margin-bottom-40" role="form">
        <input id="token" type="hidden" name="token" value="@code.Token" />
        <div class="form-group form-md-line-input">
            <div class="col-md-6">
                <div class="input-icon">
                    <input type="text" class="form-control" name="username" placeholder="帐号名/手机号">
                    <div class="form-control-focus">
                    </div>
                    <i class="fa fa-user"></i>
                </div>
            </div>
        </div>
        <div class="form-group form-md-line-input">
            <div class="col-md-6">
                <div class="input-icon right">
                    <input type="password" class="form-control" name="password" placeholder="密码">
                    <div class="form-control-focus">
                    </div>
                    <i class="fa fa-key"></i>
                </div>
                <div class="help-block">
                    with right aligned icon
                </div>
            </div>
        </div>
        <div class="form-group form-md-line-input">
            <div class="col-md-6">
                <div class="input-group">
                    <input type="text" class="form-control" name="code" placeholder="">
                    <div class="form-control-focus">
                    </div>
                    <div class="input-group-addon">
                        <img id="img" src="@code.Image" style="width: 113px; height: 30px;" />
                    </div>
                </div>
            </div>
        </div>
        <div class="form-group">
            <div class="col-md-offset-4 col-md-10">
                <button type="button" class="btn green save-button">登录</button>
            </div>
        </div>
    </form>
</div>
@Html.Partial("~/Areas/Mpa/Views/Common/Modals/_ModalFooterWithCancel.cshtml")

 

 

添加视图对应的JS文件，代码如下：

文件路径：D:\\abp version\\aspnet-zero-3.4.0\\aspnet-zero-3.4.0\\src\\MyCompanyName.AbpZeroTemplate.Web\\Areas\\Mpa\\Views\\KaiTuan\\_LoginModal.js

var _mallService = abp.services.app.mall;
(function ($) {
    app.modals.LoginModal = function () {

        var _$loginForm = null;

        var _modalManager;
        this.init = function (modalManager) {
            _modalManager = modalManager;
            //取出Form表单
            _$loginForm = _modalManager.getModal().find(‘form[name=LoginForm]‘);
        };

        this.save = function () {
            //验证不通过返回
            if (!_$loginForm.valid()) {
                return;
            }
            //序列化参数
            var login = _$loginForm.serializeFormToObject();
            _modalManager.setBusy(true);
            _mallService.login(
                login
            ).done(function (data) {
                _modalManager.close();
                abp.event.trigger(‘app.loginModalSaved‘, { username: data.username });
            }).always(function () {
                _modalManager.setBusy(false);
            });
        };
    };
    function getCode() {
        _mallService.getCode().done(function (data) {
            $("#img").attr("src", data.image);
            $("#token").val(data.token);
        });
    }

    //getCode();

    $("#img").click(function () {
        getCode();
    });
})(jQuery);

 

 

打开文件Index.js，添加如下代码：

文件路径：D:\\abp version\\aspnet-zero-3.4.0\\aspnet-zero-3.4.0\\src\\MyCompanyName.AbpZeroTemplate.Web\\Areas\\Mpa\\Views\\KaiTuan\\Index.js

6行位置添加一个变量：

var username;//记录登录拼多多用户名

 

 

26行位置添加如下代码：

/**
         登录模态框
         */
        var _loginModal = new app.ModalManager({
            viewUrl: abp.appPath + ‘Mpa/KaiTuan/LoginModal‘,
            scriptUrl: abp.appPath + ‘Areas/Mpa/Views/KaiTuan/_LoginModal.js‘,
            modalClass: ‘LoginModal‘
        });

 

 

178行位置添加如下代码：

//登录拼多多
        $("#LoginPddButton").click(function () {
            _loginModal.open();
        });

        abp.event.on(‘app.loginModalSaved‘, function (data) {
            console.info("成功", data);
            username = data.username;
            toastr["success"]("登录拼多多成功", "提示");
        });

 

 

生成解决方案，浏览器登录后台测试。
