利用uni-app写一个登录页面 包含获取手机号的接口

好的，以下是一个使用uni-app实现的登录页面，同时包含获取手机号的接口：

<template>
  <view class="container">
    <view class="form">
      <view class="form-item">
        <view class="form-label">手机号</view>
        <view class="form-input">
          <input type="tel" v-model="phone" placeholder="请输入手机号" />
        </view>
      </view>
      <view class="form-item">
        <view class="form-label">验证码</view>
        <view class="form-input">
          <input type="text" v-model="code" placeholder="请输入验证码" />
        </view>
        <view class="form-action">
          <button @click="getCode" :disabled="countdown > 0">
            {{ countdown > 0 ? countdown + '秒后重新获取' : '获取验证码' }}
          </button>
        </view>
      </view>
      <view class="form-action">
        <button @click="login">登录</button>
      </view>
    </view>
  </view>
</template>

<script>
import { getCode, login } from '@/api/user'

export default {
  data() {
    return {
      phone: '',
      code: '',
      countdown: 0,
      timer: null
    }
  },
  methods: {
    getCode() {
      if (!/^1\d{10}$/.test(this.phone)) {
        uni.showToast({
          title: '请输入正确的手机号',
          icon: 'none'
        })
        return
      }
      this.countdown = 60
      this.timer = setInterval(() => {
        this.countdown--
        if (this.countdown <= 0) {
          clearInterval(this.timer)
        }
      }, 1000)
      getCode(this.phone)
    },
    login() {
      if (!/^1\d{10}$/.test(this.phone)) {
        uni.showToast({
          title: '请输入正确的手机号',
          icon: 'none'
        })
        return
      }
      if (!/^\d{6}$/.test(this.code)) {
        uni.showToast({
          title: '请输入6位数字验证码',
          icon: 'none'
        })
        return
      }
      login(this.phone, this.code).then(res => {
        // 登录成功，进行跳转或其他操作
      })
    }
  }
}
</script>

<style scoped>
.container {
  display: flex;
  justify-content: center;
  align-items: center;
  height: 100vh;
  background-color: #f5f5f5;
}
.form {
  width: 90%;
  max-width: 400px;
  background-color: #fff;
  border-radius: 10px;
  padding: 20px;
  box-shadow: 0 2px 6px rgba(0, 0, 0, 0.1);
}
.form-item {
  display: flex;
  align-items: center;
  margin-bottom: 20px;
}
.form-label {
  flex-shrink: 0;
  width: 80px;
  font-size: 16px;
}
.form-input {
  flex-grow: 1;
}
.form-input input {
  width: 100%;
  height: 40px;
  padding: 0 10px;
  border: 1px solid #ddd;
  border-radius: 4px;
  font-size: 16px;
  outline: none;
}
.form-action {
  display: flex;
  justify-content: flex-end;
  align-items: center;
}
.form-action button {
  height: 40px;
  padding: 0 20px;
  border: none;
  background-color: #007aff;
  color: #fff;
  border-radius: 20px;
  font-size: 16px;
  outline: none;
  cursor: pointer;
}
.form-action button:disabled {
  background-color: #ddd;
  color: #666;
  cursor: not-allowed;
}
</style>

其中，`getCode`和`login`是调用接口的方法，可以根据实际情况进行实现。在这里，我使用了`uni.showToast`方法来进行提示。同时，通过设置`countdown`和`timer`来实现倒计时功能。
