无法使用应用商店保存/创建文件.js



所以我想使用 Store.js 在客户端存储上保存一个文件。

我可以使用store.set更改日期,并且可以将其log控制台以查看更改,但是它应该保存在未创建的应用程序数据中。

我试图获取保存它的路径,它是:

C:UsersUSERAppDataRoamingstoma2/Categories.json

我注意到有一个"/",所以我尝试:

C:UsersUSERAppDataRoamingstoma2Categories.json和: C:/Users/USER/AppData/Roaming/stoma2/Categories.json

但是他们三个都没有工作。

这是我的商店.js :

 const fs = require('browserify-fs');
 var fs2 = require('filereader'),Fs2 = new fs2();
 const electron = window.require('electron');
 const path = require('path');

 class Store {
     constructor(opts) {
       // Renderer process has to get `app` module via `remote`, whereas the main process can get it directly
       // app.getPath('userData') will return a string of the user's app data directory path.
       //const userDataPath = (electron.app || electron.remote.app).getPath('userData');
       var userDataPath = (electron.app || electron.remote.app).getPath('userData');
       for(var i=0;i<userDataPath.length;i++){
         if(userDataPath.charAt(i)=="\"){
           userDataPath = userDataPath.replace("\","/");
         }
       }

       // We'll use the `configName` property to set the file name and path.join to bring it all together as a string
       this.path = path.join(userDataPath, opts.configName + '.json');
       this.data = parseDataFile(this.path, opts.defaults);
       console.log(this.path);
     }
   // This will just return the property on the `data` object
   get(key) {
     return this.data[key];
   }
   // ...and this will set it
   set(key, val) {
     this.data[key] = val;
     // Wait, I thought using the node.js' synchronous APIs was bad form?
     // We're not writing a server so there's not nearly the same IO demand on the process
     // Also if we used an async API and our app was quit before the asynchronous write had a chance to complete,
     // we might lose that data. Note that in a real app, we would try/catch this.
     fs.writeFile(this.path, JSON.stringify(this.data));
   }
 }
 function parseDataFile(filePath, data) {
   // We'll try/catch it in case the file doesn't exist yet, which will be the case on the first application run.
   // `fs.readFileSync` will return a JSON string which we then parse into a Javascript object
   try {
     return JSON.parse(Fs2.readAsDataURL(new File(filePath)));
   } catch(error) {
     // if there was some kind of error, return the passed in defaults instead.
     return data;
   }
 }
 // expose the class
 export default Store;

可能存在问题 fith js.writeFile(( (嗯,这就是问题的根源(。

这是我的电话:

 //creation
 const storeDefCat = new Store({
   configName: "Categories",
   defaults: require("../data/DefaultCategorie.json")
 })
 //call for the save
 storeDefCat.set('Pizza',{id:0,path:storeDefCat.get('Pizza').path});

现在,如果可能的话,我可能需要找到另一种保存文件的方法。

我试过:fs :由于某种原因,它对我不起作用(我收到奇怪的错误,他们不想被修复..( .

如果有人有想法,那么我将不胜感激。

所以我设法解决了这个问题,为什么 fs 向我发送有关未定义函数的错误?为什么没有创建文件?它与它本身的代码无关,但导入...

为了澄清,我使用了:

const fs = require('fs');

解决方案是让它像:

const fs = window.require('fs');

只需添加window.就可以解决所有问题。由于这是我第一次使用电子,我不习惯从window导入,但似乎有必要。还有更多...没有帖子说这是修复程序。
