高德地图的汽车路线规划的路线颜色样式更改

高德用的汽车路线规划，动画回放的功能，路线颜色改不了，粗细也改不了，所以会很丑。甲方爸爸很生气，后果很严重！！！

先来欣赏一下改之前的长什么样

然后改之后看看：

是不是好看很多！！！

只贴部分代码片段哈，主要用react， 下面的代码我是写在componentDidUpdate里面的，用的高德JS API哈~

const { Map, Marker, Size, Pixel } = window.AMap
    const AMapIcon = window.AMap.Icon

// 有地图的时候设置缩放，这里是因为我们用了高清解决方案，所以在有地图的时候要设置一下scale缩放和字体大小，没有地图的时候不设置，因为之前在iPhoneX上面出现过四分之一屏的现象。
    if ((currentStatus !== 0 && currentStatus !== 1 && currentStatus !== 8 && currentStatus !== 4 && currentStatus !== 5) && currentStatus !== 13) {
      console.log('has map')
      const scale = 0.65
      window.viewportScale = 1
      const metaArr = document.head.getElementsByTagName('meta')
      for (let i = 0; i < metaArr.length; i++) {
        const metaEl = metaArr[i]
        if (metaEl.name === 'viewport') {
          metaEl.setAttribute('content', `width=device-width,user-scalable=no,initial-scale=${ scale },maximum-scale=${ scale },minimum-scale=${ scale }`)
