用vue 写一个登陆界面

由于我是AI语言模型，无法直接提供完整的代码，以下是一个简单的Vue登录界面示例：

template:

<div class="login-container">
  <form class="login-form">
    <h1>登录</h1>
    <div class="form-group">
      <label for="username">用户名：</label>
      <input type="text" id="username" v-model="username" />
    </div>
    <div class="form-group">
      <label for="password">密码：</label>
      <input type="password" id="password" v-model="password" />
    </div>
    <button type="button" @click="login">登录</button>
  </form>
</div>

script:

export default {
  data() {
    return {
      username: '',
      password: ''
    }
  },
  methods: {
    login() {
      // 登录逻辑
    }
  }
}

style:

.login-container {
  display: flex;
  justify-content: center;
  align-items: center;
  height: 100vh;
}

.login-form {
  display: flex;
  flex-direction: column;
  justify-content: center;
  align-items: center;
  padding: 20px;
  border: 1px solid #ddd;
  border-radius: 5px;
  box-shadow: 0 0 5px rgba(0, 0, 0, 0.1);
}

.form-group {
  display: flex;
  align-items: center;
  margin-bottom: 10px;
}

label {
  margin-right: 10px;
}

input {
  height: 30px;
  padding: 5px;
  border: 1px solid #ddd;
  border-radius: 5px;
  outline: none;
}

button {
  height: 40px;
  padding: 0 20px;
  background-color: #007bff;
  color: #fff;
  border: none;
  border-radius: 5px;
  outline: none;
  cursor: pointer;
}

button:hover {
  background-color: #0069d9;
}
