//在onLaunch页面下载zip文件包，并存到本地，在对zip包进行解压（zip包里面是图片），那么所有图片以及zip包都存在了本地缓存的根目录。 代码如下： onLaunch: function(obj) { this.downloadFileFn(); }, downloadFileFn: function() {     let url = wx.env.USER_DATA_PATH;     wx.setStorageSync('USER_DATA_PATH', url);     const FileSystemManager = wx.getFileSystemManager();          FileSystemManager.stat({         path: url, //文件/目录路径         recursive: true,         success: function (res) {             console.log('*******stat-成功-判断zip是否存在', url)             let isFileSystem = "N";             let list = res.stats;             for (let index in list) {                 let path = list[index].path;                 if (path == 'fileSystem.zip') {                     isFileSystem = "Y";                 }             }             if (isFileSystem == "N") {                 console.log('*******zip不存在,开始下载zip', url)                 wx.downloadFile({                     url: 'https://my.chinasie.com/attcenter/api/sys/fileSystem.zip',                     header: {                     'content-type': 'application/json',                     "Authorization": "Bearer "                     },                     success(res) {                         console.log('*******downloadFile-成功-开始保存到本地', res)                         if (res.statusCode === 200) {                             FileSystemManager.saveFile({                                 tempFilePath: res.tempFilePath,                                 filePath: url + "/fileSystem.zip",                                 success: function (res) {                                 console.log('*******saveFile-保存成功-开始解压', res)                                                                  FileSystemManager.unzip({                                     zipFilePath: `${url}/fileSystem.zip`,                                     targetPath: `${wx.env.USER_DATA_PATH}`,                                     success: function (res) {                                     console.log('-------------unzip-成功', res)                                                            FileSystemManager.stat({                                     path: url, //文件/目录路径                                     recursive: true,                                     success: function (res) {                                     debugger                                     console.log('*******stat-解压成功查看所有结果集', res)                                     },                                     fail: function (ex) {                                     console.log('*******stat-失败', ex)                                     }                                     })                     },                     fail: function (ex) {                     console.log('-------------unzip-失败', ex)                     }                     })         },     fail: function (ex) {     console.log('*******saveFile-失败', ex)     }     }) } } }) } else { console.log('*******zip已存在') } } }) }, page页面使用如下： 获取URL，在跟在解压的图片文件名， page.js let url = wx.env.USER_DATA_PATH;； this.setData({ USER_DATA_PATH:url }) page.wxml <image src='{{USER_DATA_PATH+"/agree.png"}}'></image>  图片名非真实的  <image src='{{USER_DATA_PATH+"/login-banner1.jpg"}}'></image>  <image src='{{USER_DATA_PATH+"/department.png"}}'></image> 如图： iOS  图片读取不出来   [图片] 如图： 安卓手机  图片可以读取出来   [图片] [图片] 能否知情中尽快回复，比较着急，非常感谢。
