微信小程序canvas type=2d生成海报保存到相册、文字换行溢出显示...、文字删除线、分享面板

做个简单的生成二维码海报分享，我做的时候也找简单的方法看能不能实现页面直接截图那种生成图片，原生小程序不支持，不多介绍下面有全部代码有注释、参数自行替换运行看看，有问题可以咨询我，我写的已经上线

效果如图：

 js:

// 产品详情
import {
  getProductDetails,
  getDataList,
  getShareData,
  getUnlimitedQRCode
} from "../../../../../api/dsxapi";
const ui = require("../../../../../utils/ui");

    id: null, //跳转传过来的产品id
    datas: null, //详情数据
    images: null, //轮播图
    current: 0,
    proTags: null, //产品标签
    images2: null, //详情图片
    routeId: null, //哪里打开的
    show: false, //遮罩层
    showShare: false, //分享面板
    shareImg: false, //控制分享图标
    options: [{

      },
      {
        name: '生成分享图',
        icon: 'https://wx.applet.style.51dsx.cn/img/share_button_fxt.png'
      },
    ],
    posterDatas: {
      width: 281, //画布宽度
      height: 460, //画布高度
      // 缓冲区，无需手动设定
      pic: null,
      buttonType: 1,
      show: false, // 显示隐藏跳转设置
      success: false, // 是否成功生成过海报
      canvas: null, // 画布的节点
      ctx: null, // 画布的上下文
      dpr: 1, // 设备的像素比
    },
    QRcodeImg: null, //小程序二维码
    photoWidth: null //产品图片宽度
  },
