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(
`${this.host}api/TokenAuth/SendTwoFactorAuthenticateCaptcha`,
"post",
{
provider: "Phone",
userId: this.twoFactorData.userId,
}
)
.catch((re) => {
var res = re.response.data;
this.errorMessage(res.error.message);
})
.then((re) => {
var res = re.data.result;
this.showTwoFactorSuccess = true;
this.showTwoFactorSuccess = false;
this.successMessage("发送验证码成功");
});
},
request 是利用axios库发送带有访问凭证Header请求功能的封装 ，ajaxRequest.ts请参考博文使用 Abp.Zero 搭建第三方登录模块（三）：网页端开发
这里使用js-cookie库获取cookie中的访问凭证，并添加到Header中
import { request } from "@/ajaxRequire";
import Cookies from "js-cookie";
const tokenKey = "main_token";
const setToken = (token: string) => Cookies.set(tokenKey, token);
const cleanToken = () => Cookies.remove(tokenKey);
const getToken = () => Cookies.get(tokenKey);
登录
编写登录函数handleLogin:
async handleLogin() {
this.loading = true;
var userNameOrEmailAddress = this.loginForm.username;
var password = this.loginForm.password;
var twoFactorAuthenticationToken =
this.loginForm.twoFactorAuthenticationToken;
var twoFactorAuthenticationProvider =
this.loginForm.twoFactorAuthenticationProvider;
userNameOrEmailAddress = userNameOrEmailAddress.trim();
await request(`${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;
}
"
>
<el-alert
v-if="showTwoFactorSuccess"
title="验证码已发送至用户的手机号，请查收"
type="info"
>
</el-alert>
</el-col>
<el-col :span="24">
<el-form-item
class="item"
prop="twoFactorAuthenticationToken"
>
<el-input
v-model="loginForm.twoFactorAuthenticationToken"
:placeholder="'发送验证码后键入验证码'"
tabindex="2"
autocomplete="on"
@blur="capsTooltip = false"
>
<el-button
slot="append"
:disabled="smsSendCd > 0"
@click="sendVerificationCode"
>{{
smsSendCd == 0 ? "发送验证码" : smsSendCd + "后重试"
}}</el-button
>
</el-input>
</el-form-item>
</el-col>
</el-row>
</el-tab-pane>
<el-tab-pane
:lazy="true"
label="邮箱验证"
name="Email"
:disabled="
twoFactorData.twoFactorAuthenticationProviders.indexOf(
'Email'
) == -1
"
>
<el-row>
<el-col :span="24">
<el-alert
v-if="showTwoFactorSuccess"
title="验证码已发送至登录用户对应的邮箱，请查收"
type="info"
>
</el-alert>
</el-col>
<el-col :span="24">
...
</el-col>
</el-row>
</el-tab-pane>
</el-tabs>
</template>
<el-row type="flex" class="row-bg" justify="center" :gutter="10">
<el-col :span="10" v-if="twoFactorData != null">
<el-button
:loading="loading"
style="width: 100%"
@click.native.prevent="twoFactorData = null"
>
返回
</el-button>
</el-col>
<el-col :span="10">
<el-button
:loading="loading"
type="primary"
style="width: 100%"
@click.native.prevent="handleLogin"
>
{{ twoFactorData == null ? "登录" : "继续" }}
</el-button>
</el-col>
</el-row>
</el-form>
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");
});
}
最终效果
