电子应用将数据存储到系统时会崩溃（用代码3221225477退出的应用程序）

Question

我正在使用电子应用程序，并且正在使用以下类实现来保存和检索用户磁盘的数据。但是，有时此功能正确，有时该程序会崩溃并输出此错误。

用代码3221225477退出的应用程序

我不太确定是什么原因导致了此问题。我了解此错误代码意味着发生了违反访问的情况，但是我不确定为什么会发生访问。可能是班级的实施。我只是从这里拿出实施

也有没有随机发生这种情况，因此可能不是商店实现。

const electron = require('electron');
const path = require('path');
const fs = require('fs');


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');
    // 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);
  }
  
  // This will just return the property on the `data` object
  get(key) {
    const val = this.data[key];
    console.log('Get', key, val);
    return val;
  }
  
  // ...and this will set it
  set(key, val) {
    console.log('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.writeFileSync(this.path, JSON.stringify(this.data));
  }
}

function parseDataFile(filePath, defaults) {
  // 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(fs.readFileSync(filePath));
  } catch(error) {
    // if there was some kind of error, return the passed in defaults instead.
    return defaults;
  }
}

// expose the class
module.exports = Store;
