谢谢，让前端传给后端

好像读不了，可以用事件试试。 后端：

$[tauri::command]
fn get_local_storage<R: tauri::Runtime>(app:tauri::AppHandle<R>){
  app.emit_all("tauri://get-local-storage");
}

然后前端：

async function sendLocalStorage(){
  const tauriApi = await import('@tauri-apps/api');
  const {event:{listen,emit}} = tauriApi;
  listen('tauri://get-local-storage',() => {
     emit('local-storage',{key:'key',value:localStorage.getItem(key)})
  })
}

然后后端：

fn main() {
  tauri::Builder::default()
    .setup(|app| {
      app.listen_global("local-storage", |event| {
        println!("got event-name with payload {:?}", event.payload());
      });
      Ok(())
    })
    .run(tauri::generate_context!())
    .expect("failed to run app");
}

大概是这个流程吧

localStorage?
