Vue elementUI实现免密登陆与号码绑定功能

前言

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。

首先来编写发送验证码函数，登录，绑定，解绑的业务都需要发送验证码功能，通过currentVerifyingType 来区别当前验证码种类。也就是在服务端的Purpose目的。

VerifyingType 可以为LOGIN，UNBIND_PHONENUMBER或BIND_PHONENUMBER

async sendVerificationCode(phoneNumber, type) {
    this.currentVerifyingType = type;
    this.smsSendCd = 60;
    this.timer = setInterval(() => {
    this.smsSendCd--;
    if (this.smsSendCd <= 0) {
        clearInterval(this.timer);
    }
    }, 1000);
    await request(`${this.host}${this.prefix}/Captcha/Send`, "post", {
    userId: this.userInfo == null ? null : this.userInfo.id,
    phoneNumber: phoneNumber,
    type: type,
    })
    .catch((re) => {
        var res = re.response.data;
        this.errorMessage(res.error.message);
    })
    .then((re) => {
        var res = re.data.result;
        this.successMessage("发送验证码成功");
    });
}

注意几个关键的全局变量

userInfo: null,                   //用户对象
currentVerifyingType: null,       //当前发送验证码的用途
smsSendCd: 0,                     //发送验证码的冷却时间，默认60s
loginForm: {                      //登录对象
username: "",
password: "",
},
token: null,                      //登录凭证Token
verifyNumber: null,               //填写的验证码

登录功能

创建手机号输入控件

<el-input
    ref="username"
    v-model="loginForm.username"
    :placeholder="'请输入手机号'"
    type="text"
    tabindex="1"
    autocomplete="on">
    <template slot="prepend">+86</template>
</el-input>

创建验证码控件，并添加一个按钮用于发送验证码，点击后触发sendVerificationCode

<el-input
    ref="password"
    v-model="loginForm.password"
    :type="passwordType"
    :placeholder="'发送验证码后键入验证码'"
    tabindex="2"
    autocomplete="on"
    @blur="capsTooltip = false"
    @keyup.enter.native="handleLogin"
    >
    <el-button
        slot="append"
        :disabled="smsSendCd > 0"
        @click="sendVerificationCode(loginForm.username, 'LOGIN')"
        >{{
        smsSendCd == 0 ? "发送验证码" : smsSendCd + "后重试"
        }}
    </el-button>
</el-input>

登录函数，将验证电话号码（即用户名）和验证码

async handleLogin() {
    this.loading = true;
    let phoneNumber = this.loginForm.username;
    let password = this.loginForm.password;
    phoneNumber = phoneNumber.trim();
    await request(`${this.host}api/TokenAuth/Authenticate`, "post", {
    phoneNumber,
    password,
    });
}

登录完成后，将Token存入Cookie

.then(async (res) => {
    var data = res.data.result;
    setToken(data.accessToken);

绑定/解绑功能

创建新手机号输入框，若没有绑定手机，附带绑定按钮，按下后将发送验证码；若已绑定手机，需要先解绑，才能绑定新号码，附带解绑按钮，按下后将发送验证码

<el-input v-model="userInfo.phoneNumber"> </el-input>
<el-button
    v-if="!userInfo.isPhoneNumberConfirmed"
    size="mini"
    type="primary"
    :disabled="smsSendCd > 0"
    @click="
    sendVerificationCode(userInfo.phoneNumber, 'BIND_PHONENUMBER')
    "
    >{{ smsSendCd == 0 ? "验证手机号" : smsSendCd + "后重试" }}
</el-button>
<el-button
    v-else
    size="mini"
    type="danger"
    :disabled="smsSendCd > 0"
    @click="
    sendVerificationCode(userInfo.phoneNumber, 'UNBIND_PHONENUMBER')
    "
    >{{ smsSendCd == 0 ? "解绑手机号" : smsSendCd + "后重试" }}
</el-button>

创建校验短信验证码控件

<el-input v-model="verifyNumber">
    <el-button
        slot="append"
        type="primary"
        size="mini"
        @click="verify">
        完成验证
    </el-button>
</el-input>

创建校验短信验证码函数，

async verify() {
    var action = null;
    if (this.currentVerifyingType == "BIND_PHONENUMBER") {
    action = "Bind";
    } else if (this.currentVerifyingType == "UNBIND_PHONENUMBER") {
    action = "Unbind";
    } else {
    action = "Verify";
    }
    await request(`${this.host}${this.prefix}/Captcha/${action}`, "post", {
    token: this.verifyNumber,
    })
    .catch((re) => {
        var res = re.response.data;
        this.errorMessage(res.error.message);
    })
    .then((re) => {
        var res = re.data;
        if (res.success) {
        this.successMessage("绑定成功");
        window.location.reload()   
        }
    });
}

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>{<!--{cke_protected}{C}%3C!%2D%2D%20%2D%2D%3E-->{ 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");
    });
}

此函数将在成功登录之后调用，也用于已登录状态的情况下，打开网页时调用，在handleLogin函数中，在请求登录api后编写续操作

.then(async (res) => {
    var data = res.data.result;
    setToken(data.accessToken);
    await this.getCurrentUser();
})

获取用户信息功能

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;
},

至此，已完成了所有的工作
