这2天微信小程序加强了eval的审核限制，用了这个库一直审核不通过，麻烦看看是不是哪里违反了限制

我是参照官方示例来引用线上文件包的，版本：[email protected]

lottieCreate(wx.createCanvasContext('lottie-cat'), {
  path: 'https://xxxx/cat.zip',
  width: 400,// 可不传
  height: 400// 可不传
})

// 创建lottie动画
function lottieCreate(canvasContext, { path, width, height }) {
  const lottie = require('./lottie').default// 引用本库文件

  if (!canvasContext || !path) return

  if (!width || !height) {// 不传默认设屏幕尺寸
    const systemInfo = wx.getSystemInfoSync()
    width = systemInfo.windowWidth
    height = systemInfo.windowHeight
  }
  console.log('canvas尺寸：', width, height)

  canvasContext.canvas = {
    width,
    height,
  }

  Object.defineProperty(canvasContext, "globalAlpha", {
    get() {
      return this._globalAlpha
    },
    set(value) {
      this._globalAlpha = value
    },
  })
  canvasContext.globalAlpha = 1
  return lottie.loadAnimation({
    renderer: "canvas",
    loop: true,
    autoplay: true,
    path,
    rendererSettings: {
      context: canvasContext,
      clearCanvas: true,
    },
  })
}

兄弟，你这个问题怎么解决？有可替代的库吗

@vcxiaohan @sky-chy 由于 lottie web 内部会有 eval 逻辑， 所以 lottie-miniapp 为了保持同步内部实现 eval

https://github.com/airbnb/lottie-web/blob/master/player/js/utils/expressions/ExpressionManager.js#L437 https://github.com/landn172/lottie-miniapp/blob/master/src/lottie/utils/expressions/ExpressionManager.js#L446

可以尝试自行编译将这行代码注释，尝试下是否可以运行 （某些lottie 文件会涉及到此处）。

可以使用官方维护方案 https://developers.weixin.qq.com/miniprogram/dev/platform-capabilities/extended/utils/api-typings.html
