Electron Dialog的使用以及打开目录、文件以及读写配

需求：在Electron中我期望打开某个目录，修改其目录下的某个配置文件
要打开目录、或者文件，就需要用到Electron的dialog。
该Api只支持再主程序使用，其他程序要使用就需要跟着下面步骤走。
第一步，引入：@electron/remote 新版取消了remote

npm install --save @electron/remote

第二步，再主程序中使用它。
1.引入remote模块
const remote = require("@electron/remote/main");
2.启用remote模块，渲染进程就可以使用主程序模块
remote.enable(win.webContents);
完整background.js代码

"use strict";

import { app, protocol, BrowserWindow } from "electron";
import { createProtocol } from "vue-cli-plugin-electron-builder/lib";
import installExtension, { VUEJS_DEVTOOLS } from "electron-devtools-installer";
const isDevelopment = process.env.NODE_ENV !== "production";
const path = require("path");
// *************************1.引入remote模块******************************
const remote = require("@electron/remote/main");
remote.initialize();
// Scheme must be registered before the app is ready
protocol.registerSchemesAsPrivileged([
  { scheme: "app", privileges: { secure: true, standard: true } },
]);

async function createWindow() {
  // Create the browser window.
  const win = new BrowserWindow({
    // 初始窗口
    width: 1200,
    height: 900,
    // 全屏
    // fullscreen: true,
    autoHideMenuBar: true, //隐藏菜单
    icon: "./icon.ico",
    webPreferences: {
      nodeIntegration: true, // 使渲染进程拥有node环境
      //关闭web权限检查，允许跨域
      webSecurity: false,
      // Use pluginOptions.nodeIntegration, leave this alone
      // See nklayman.github.io/vue-cli-plugin-electron-builder/guide/security.html#node-integration for more info
      nodeIntegration: process.env.ELECTRON_NODE_INTEGRATION,
      contextIsolation: !process.env.ELECTRON_NODE_INTEGRATION,
    },
  });
  // ********2.启用remote模块，渲染进程就可以使用主程序模块********************
  remote.enable(win.webContents);
  if (process.env.WEBPACK_DEV_SERVER_URL) {
    // Load the url of the dev server if in development mode
    await win.loadURL(process.env.WEBPACK_DEV_SERVER_URL);
    if (!process.env.IS_TEST) win.webContents.openDevTools();
  } else {
    createProtocol("app");
    // Load the index.html when not in development
    win.loadURL("app://./index.html");
  }
}

// Quit when all windows are closed.
app.on("window-all-closed", () => {
  // On macOS it is common for applications and their menu bar
  // to stay active until the user quits explicitly with Cmd + Q
  if (process.platform !== "darwin") {
    app.quit();
  }
});

app.on("activate", () => {
  // On macOS it's common to re-create a window in the app when the
  // dock icon is clicked and there are no other windows open.
  if (BrowserWindow.getAllWindows().length === 0) createWindow();
});

// This method will be called when Electron has finished
// initialization and is ready to create browser windows.
// Some APIs can only be used after this event occurs.
app.on("ready", async () => {
  if (isDevelopment && !process.env.IS_TEST) {
    // Install Vue Devtools
    try {
      await installExtension(VUEJS_DEVTOOLS);
    } catch (e) {
      console.error("Vue Devtools failed to install:", e.toString());
    }
  }
  createWindow();
});

// Exit cleanly on request from parent process in development mode.
if (isDevelopment) {
  if (process.platform === "win32") {
    process.on("message", (data) => {
      if (data === "graceful-exit") {
        app.quit();
      }
    });
  } else {
    process.on("SIGTERM", () => {
      app.quit();
    });
  }
}

完成以上两个步揍后，我就可以在其他窗口使用dialog了。
话不多说，直接先上HTML代码：

            <el-form :model="form" label-width="120px">
                <el-form-item label="请选择你的文件:">
                    <el-input v-model="filePath" placeholder="请选择你的文件" readonly @click="selectDirectory"/>
                </el-form-item>
            </el-form>
            <el-row>
                <el-button @click="readFile">读取配置文件</el-button>
                <el-button @click="writeFile">写入配置文件</el-button>
            </el-row>

引入

const { dialog } = require('@electron/remote')
console.log(dialog, 'dialog')
//引入node原生fs模块
const fs = require("fs")
//引入node原生读写配置
const ini = require('ini');

数据源data中

    data() {
        return {
            filePath: "",
            config:null,
        }
    },

methods中

    methods: {
        selectDirectory() {
            dialog.showOpenDialog({
                properties: ["openFile"] // 选择文件
                // properties: ["openDirectory"] // 选择目录
            }).then((results) => {
                // console.log(results.filePaths);
                // console.log(results.canceled);
                this.filePath = results.filePaths[0];
            })
        },
        // 读取配置文件
        readFile(){
            
            if(!this.filePath){
                this.errMsg("请先选择文件")
                return
            }
            this.config = ini.parse(fs.readFileSync(this.filePath).toString());
            console.log(this.config,'config')
        },
        // 写配置文件
        writeFile(){
            if(!this.config){
                this.errMsg("请先读取文件")
                return
            }
            this.config.xxxxx = "你想要修改的值"
            fs.writeFileSync(this.filePath, ini.stringify(this.config))
        },
        errMsg(msg){
            dialog.showErrorBox("错误信息",msg);
        },
    }
