"data" 参数必须是字符串类型或 Buffer、TypedArray 或 DataView 的实例。接收到对象实例

Question

一旦有人在填写文本输入并回答 html 中的所有问题后单击“创建口袋妖怪数据”按钮，我想使用 json 创建口袋妖怪数据的保存文件但出于某种原因，我收到此错误

(node:30348) UnhandledPromiseRejectionWarning: TypeError [ERR_INVALID_ARG_TYPE]: The "data" argument must be of type string or an instance of Buffer, TypedArray, 
or DataView. Received an instance of Object
    at Object.writeFile (node:fs:2106:5)
    at E:\Pogramming folder\Pokehunt Streamers Tool\app\pokehunt\src\index.js:48:10

这是我的代码这是 renderer.js

const fs = require('fs');
const {ipcRenderer} = require('electron');

var coll = document.getElementsByClassName("collapsible");
var i;

for (i = 0; i < coll.length; i++) {
  coll[i].addEventListener("click", function() {
    this.classList.toggle("active");
    var content = this.nextElementSibling;
    if (content.style.display === "block") {
      content.style.display = "none";
    } else {
      content.style.display = "block";
    }
  });
}
let hunt = 
    {
        "name": "",
        "imageurl": "",
        "method": "",
        "timer": "00:00:00",
        "counter" : 0,
        "shinycharm": false
    };

document.getElementById("startBtn").addEventListener("click",()=>{
    console.log("click!");
    const pokename = document.getElementById("pokemon").value;
    if(pokename!=null){
        hunt.name = pokename;
        hunt.imageurl = 'https://poketch-cdn-assets.s3.amazonaws.com/images/pokemon/animated/shiny/${hunt.name}.gif';
        const selectMethod = document.getElementById("Method");
        hunt.method = selectMethod.value;
        const shinycharm = document.getElementById("shiny");
        switch(shinycharm){
            case "no":
                hunt.shinycharm = false;
                break;
            case "yes":
                hunt.shinycharm = true;
                break;
        }
        //for testing I did this log stuff
        console.log(JSON.stringify(hunt));
        const huntfinal = JSON.stringify(hunt);
        ipcRenderer.send("create-document-trigger",huntfinal);
    } else{
        hunt.name = "shinx";
    }
});

这是我的main.js

const { app, BrowserWindow, ipcMain, nativeTheme, dialog } = require('electron');
const path = require('path');
const fs = require('fs');

// Handle creating/removing shortcuts on Windows when installing/uninstalling.
if (require('electron-squirrel-startup')) { // eslint-disable-line global-require
  app.quit();
}
let mainWindow;
const createWindow = () => {
  // Create the browser window.
  mainWindow = new BrowserWindow({
    width: 955,
    height: 975,
    autoHideMenuBar: true,
    webPreferences:{
      enableRemoteModule: true,
      nodeIntegration: true,
      contextIsolation: false,
    }
  });

  // and load the index.html of the app.
  mainWindow.loadFile(path.join(__dirname, 'index.html'));

  // Open the DevTools.
  mainWindow.webContents.openDevTools();

  //dark mode
  ipcMain.handle('dark-mode:toggle', () => {
    if (nativeTheme.shouldUseDarkColors) {
      nativeTheme.themeSource = 'light'
    } else {
      nativeTheme.themeSource = 'dark'
    }
    return nativeTheme.shouldUseDarkColors
  })

  ipcMain.handle('dark-mode:system', () => {
    nativeTheme.themeSource = 'system'
  })

  ipcMain.on("create-document-trigger",(hunt)=>{
    dialog.showSaveDialog(mainWindow,{
      filters: [{name:"json files",extensions:["json"]}]
    }).then(({filePath}) =>{
      console.log("filepath: "+filePath);
      fs.writeFile(filePath,hunt,(err)=>{
        if(err){
          console.log(err.message);
        }
      })
    })
  })
};


app.on('ready', createWindow);

app.on('window-all-closed', () => {
  if (process.platform !== 'darwin') {
    app.quit();
  }
});

app.on('activate', () => {
  if (BrowserWindow.getAllWindows().length === 0) {
    createWindow();
  }
});

console.log 给我 {"name":"shinx","imageurl":"https://poketch-cdn-assets.s3.amazonaws.com/images/pokemon/animated/shiny/${hunt.name}.gif","method":"pokeradar","timer":"00h:00m:00s","counter":0,"shinycharm":false} 这几乎是（gif URL 没有放宠物小精灵的名字，但这是我稍后会解决的另一个问题）正是我在 json 文件，但代码无法创建此 json 文件。

Answer 1

我能够解决这个问题。

我把ipcMain.on("create-document-trigger",(hunt)=>{换成了ipcMain.on("create-document-trigger",(event,data) =>{

现在代码看起来像这样并且可以工作

  ipcMain.on("create-document-trigger",(event,data) =>{
    dialog.showSaveDialog(mainWindow,{
      filters: [{name:"json files",extensions:["json"]}]
    }).then(({filePath}) =>{
      console.log("filepath: "+filePath);
      fs.writeFile(filePath,data,(err)=>{
        if(err){
          console.log(err.message);
        }
      })
    })
  })
