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");},});},});},
