项目地址

前端代码的框架采用vue.js + elementUI 这套较为简单的方式实现，以及typescript语法更方便阅读。

首先添加全局对象：

loginForm: 登录表单对象
twoFactorData: 两步验证数据，
showTwoFactorSuccess: 是否显示两步验证成功提示

loginForm: {
    //登录对象
    username: "",
    password: "",
    twoFactorAuthenticationToken: "",
    twoFactorAuthenticationProvider: "Phone",
},
twoFactorData: null,
showTwoFactorSuccess: false,

发送验证码

编写发送验证码函数sendVerificationCode，发送验证码后，启动定时器，60秒后可以再次发送验证码。

   async sendVerificationCode() {
      this.smsSendCd = 60;
      this.timer = setInterval(() => {
        this.smsSendCd--;
        if (this.smsSendCd <= 0) {
          clearInterval(this.timer);
        }
      }, 1000);
      await request(
        `${this.host}api/TokenAuth/SendTwoFactorAuthenticateCaptcha`,
        "post",
        {
          provider: "Phone",
          userId: this.twoFactorData.userId,
        }
      )
        .catch((re) => {
          var res = re.response.data;
          this.errorMessage(res.error.message);
        })
        .then((re) => {
          var res = re.data.result;
          this.showTwoFactorSuccess = true;
          this.showTwoFactorSuccess = false;
          this.successMessage("发送验证码成功");
        });
    },

request 是利用axios库发送带有访问凭证Header请求功能的封装，ajaxRequest.ts请参考博文使用 Abp.Zero 搭建第三方登录模块（三）：网页端开发

这里使用js-cookie库获取cookie中的访问凭证，并添加到Header中

import { request } from "@/ajaxRequire";
import Cookies from "js-cookie";

const tokenKey = "main_token";
const setToken = (token: string) => Cookies.set(tokenKey, token);
const cleanToken = () => Cookies.remove(tokenKey);
const getToken = () => Cookies.get(tokenKey);

 async handleLogin() {
      this.loading = true;

      var userNameOrEmailAddress = this.loginForm.username;
      var password = this.loginForm.password;

      var twoFactorAuthenticationToken =
        this.loginForm.twoFactorAuthenticationToken;
      var twoFactorAuthenticationProvider =
        this.loginForm.twoFactorAuthenticationProvider;

      userNameOrEmailAddress = userNameOrEmailAddress.trim();
      await request(`${this.host}api/TokenAuth/Authenticate`, "post", {
        userNameOrEmailAddress,
        password,
        twoFactorAuthenticationToken,
        twoFactorAuthenticationProvider,
      })
        .catch((re) => {
          var res = re.response.data;
          this.errorMessage(res.error.message);
        })
        .then(async (res) => {
          var data = res.data.result;
          if (data.requiresTwoFactorAuthenticate) {
            this.twoFactorData = data;
          } else {
            setToken(data.accessToken);
            setRememberClientToken(data.rememberClientToken);
            await this.getCurrentUser();
          }
        })
        .finally(() => {
          setTimeout(() => {
            this.loading = false;
          }, 1.5 * 1000);
        });
    },

请注意，当需要进行两步验证时，requiresTwoFactorAuthenticate会返回true，同时返回
twoFactorAuthenticationProviders。

退出登录

登出, 将Token以及用户信息置空

<el-button
    :loading="loading"
    type="danger"
    style="width: 100%"
    @click.native.prevent="logout">
    退出登录
</el-button>

logout() {
    setToken(null);
    this.token = null;
    this.userInfo = null;
},

界面控件

在登录表单的HTML中，添加两步验证控件：
显示规则为，当需要两步验证时（即twoFactorData不为空），显示两步验证控件，否则显示登录控件。

根据twoFactorAuthenticationProviders。我们采用了两种方式，一种是短信验证码，一种是邮箱验证码，这里我们采用了elementUI的tab组件，来实现两种方式的切换。

     <el-form
        ref="loginForm"
        :model="loginForm"
        class="login-form"
        autocomplete="on"
        label-position="left"
      >
        <template v-if="twoFactorData == null">
            ...
        </template>
        <template v-else>
          <p>您的账号开启了两步验证，请选择一种认证方式以继续登录</p>
          <el-tabs
            v-model="loginForm.twoFactorAuthenticationProvider"
            tab-position="top"
          >
            <el-tab-pane
              :lazy="true"
              label="SMS短信验证"
              name="Phone"
              :disabled="
                twoFactorData.twoFactorAuthenticationProviders.indexOf(
                  'Email'
                ) == -1
              "
            >
              <el-row>
                <el-col
                  :span="24"
                  style="
                     {
                      margin-bottom: 10px;
                    }
                  "
                >

用Abp实现两步验证（Two-Factor Authentication，2FA）登录（二）：Vue网页端开发

获取用户信息功能

登录成功后我们要拿到当前用户的信息，存入userInfo对象，并在页面上简单展示

<span>{{ userInfo }}</span>

创建一个获取当前用户的函数

async getCurrentUser() {
    await request(
    `${this.host}${this.prefix}/User/GetCurrentUser`,
    "get",
    null
    )
    .catch((re) => {
        var res = re.response.data;
        this.errorMessage(res.error.message);
    })
    .then(async (re) => {
        var result = re.data.result as any;
        this.userInfo = result;
        this.token = getToken();
        clearInterval(this.timer);

        this.smsSendCd = 0;
        this.currentVerifyingType = null;

        this.successMessage("登录成功");
    });
}
