微信小程序显示PDF文件

需求：在小程序中显示PDF文件
思路：wx.openDocument打开新的网页，显示PDF文件

<view @click="showPdf">点击查看协议</view>
 
showPdf() {
    // let url = otption.currentTarget.dataset.index.keyValue;
    let url =
      "https://fs.mufengweilai.com/api/gym/2024/01/22/84f266eafdc945ac8e55f84da1693687.pdf";
    //打开pdf文件
    wx.showLoading({
      title: "加载中...",
    });
    wx.downloadFile({
      url: url,
      success: function (res) {
        const filePath = res.tempFilePath;
        wx.openDocument({
          filePath: filePath,
          success: function (res) {
            wx.hideLoading();
          },
          fail: function (res) {
            console.log("打开失败");
          },
        });
      },
    });
  },
