微信小程序需要wxml，wxss，js三種類型代碼

1，wxml

<view class="container">
  <view class="title">兔年頭像生成器</view>
  <view class="description">選擇一張圖片，生成你的兔年頭像吧！</view>
  <image class="avatar" src="{{avatarUrl}}"></image>
  <button class="btn" bindtap="onButtonClick">生成頭像</button>
  <view class="result" wx:if="{{result}}">{{result}}</view>
</view>

2，wxss

.container {
    display: flex;
    flex-direction: column;
    align-items: center;
    justify-content: center;
    height: 100vh;
  }
  
  .title {
    font-size: 24px;
    font-weight: bold;
    margin-bottom: 20px;
  }
  
  .description {
    font-size: 18px;
    color: #666;
    margin-bottom: 30px;
  }
  
  .avatar {
    width: 200px;
    height: 200px;
    margin-bottom: 30px;
  }
  
  .btn {
    width: 200px;
    height: 40px;
    background-color: #007aff;
    color: #fff;
    border-radius: 20px;
  }
  
  .result {
    margin-top: 30px;
    font-size: 18px;
    color: #f00;
  }

Page({
    data: {
      avatarUrl: '/images/default-avatar.jpg',
      result: ''
    },
    onButtonClick: function() {
      wx.chooseImage({
        count: 1,
        success: res => {
          const tempFilePath = res.tempFilePaths[0];
          wx.getImageInfo({
            src: tempFilePath,
            success: res => {
              wx.showLoading({
                title: '頭像生成中',
              });
              const ctx = wx.createCanvasContext('canvas');
              ctx.drawImage(res.path, 0, 0, 400, 400);
              const rabbitImage = '/images/rabbit.png';
              ctx.drawImage(rabbitImage, 250, 0, 150, 150);
              const rabbitEarsImage = '/images/rabbit-ears.png';
              ctx.drawImage(rabbitEarsImage, 230, -20, 200, 200);
              const rabbitNoseImage = '/images/rabbit-nose.png';
              ctx.drawImage(rabbitNoseImage, 280, 120, 100, 100);
              ctx.draw(false, () => {
                wx.canvasToTempFilePath({
                  canvasId: 'canvas',
                  success: res => {
                    this.setData({
                      avatarUrl: res.tempFilePath,
                      result: '頭像已生成！'
                    });
                    wx.hideLoading(); // 隱藏加載動畫
                  },
                  fail: err => {
                    console.error(err);
                    wx.hideLoading(); // 隱藏加載動畫
                  }
                });
              });
            },
            fail: err => {
              console.error(err);
            }
          });
        },
        fail: err => {
          console.error(err);
        }
      });
    }
  })
