electron-vue ipcRenderer.on() 調用多次

  methods: {
    isSave (ev) {
      this.localFileUrl = ev.localFileUrl // 本地的路徑
      ipcRenderer.send('save-dialog', ev.localFileUrl)
      ipcRenderer.on('saveFile', (event, path1) => {
        if (!path1) path1 = '無路徑'
        console.log(path1)  // 打印很多次,不會關
        // this.copyFile(ev.localFileUrl, path1)
        // fs.createReadStream(ev.localFileUrl).pipe(fs.createWriteStream(path1))
      })
    }
}

自己解決的方式,在created中監聽就不會有這個問題

  created () {
    ipcRenderer.on('saveFile', (event, path1) => {
      if (!path1) path1 = '無路徑'
      console.log(path1)
      // this.copyFile(ev.localFileUrl, path1)
      // fs.createReadStream(ev.localFileUrl).pipe(fs.createWriteStream(path1))
    })
  },
