好像是因为wx.previewImage导致的问题，

比如下列代码，点击按钮，获取网络图片，得到本地路径，再通过wx.getImageInfo校验文件路径是否可读，

可以读取，记录当前路径，且用wx.previewImage显示，

第二次点击按钮，路径已经记录过，再通过wx.getImageInfo校验文件路径是否可读，

MIX2返回 “getImageInfo:fail:file not found”

Page({     data: {         result: ''     },     doButton: function () {         if (this.data.result) {             wx.getImageInfo({                 src: this.data.result,                 success(res1) {                     console.log('第2次1', res1.path);                     wx.previewImage({                         urls: [res1.path]                     });                 },                 fail(err1) {                     console.log('第2次1', err1.errMsg);                 }             });         } else {             let _this = this;             wx.getImageInfo({                 src: 'http://a.hiphotos.baidu.com/image/pic/item/faf2b2119313b07eaad49f0c00d7912397dd8c4d.jpg',                 success(res1) {                     console.log('第1次1', res1.path);                     wx.getImageInfo({                         src: res1.path,                         success(res2) {                             console.log('第1次2', res2.path);                             _this.data.result = res2.path;                             wx.previewImage({                                 urls: [res2.path]                             });                         },                         fail(err2) {                             console.log('第1次2', err2.errMsg);                         }                     });                 },                 fail(err1) {                     console.log('第1次1', err1.errMsg);                 }             });         }     } })
