</script>

<template>
  <view class="viewport">
    <view class="logo">
      <image
        src="https://pcapi-xiaotuxian-front-devtest.itheima.net/miniapp/images/logo_icon.png"
      ></image>

          <button>
            <text class="icon icon-phone">模拟快捷登录</text>
          </button>
        </view>
      </view>
      <view class="tips">登录/注册即视为你同意《服务条款》和《小兔鲜儿隐私协议》</view>
    </view>
  </view>
</template>

<style lang="scss">

      position: relative;
      text {

  left: 20rpx;
  right: 20rpx;

  text-align: center;
}
</style>

二、定义接口

复制代码

//src/services/login.ts
export type LoginParams = {
  code: string
  encryptedData: string
  iv: string
}

/**
 * 小程序登录
 * @param data 请求参数
 */
export const postLoginWxMin = (data: LoginParams) => {
  return http({
    method: 'POST',
    url: '/login/wxMin',
    data,
  })
}
