Tauri 技术教程 * 第六章 Tauri的实战教程
第六节托盘、请求完善

一. 简介

在上面的章节我们完成了窗口和请求功能的实现，本章节我们将对系统现有的代码进行修改，以实现完整的功能。

二. 托盘完善

打开项目中 “tary.rs”文件，我们在之前介绍了如何创建和定义托盘菜单，但在实现部分并没有实现它，下面我们来看看它的具体功能和如何实现它。

1. 点击事件

点击托盘图标时，我们希望展示应用界面到桌面最前面，它的逻辑在：on_tray_icon_event 实现处理，它接收2各参数，

TrayIcon

  id: TrayIconId,
  inner: tray_icon::TrayIcon,
  app_handle: AppHandle<R>,

TrayIconEvent

实现思路：点击托盘图标，获取Tauri的主窗口，并显示它。

实现代码如下：

 let main_win=tray.app_handle().get_webview_window("main").unwrap();
 main_win.show().unwrap();
 main_win.unminimize().unwrap();
 main_win.set_focus().unwrap();

2. 显示事件

显示事件和点击事件的实现思路一致，这里提供另外一种代码：

....
 "show" => {
    for (key, value) in app.webview_windows() {
        if key == "main" {
            value.show().unwrap();
        }
    }
}
....

3. 退出事件

"quit" => {
    app.exit(0);
}

调用app.exit api 就可以

4. 完整代码如下：

use tauri::{
    menu::{Menu, MenuItem, Submenu},
    tray::{MouseButton, MouseButtonState, TrayIconBuilder, TrayIconEvent},
    Manager, Runtime,
};

pub fn create_tray<R: Runtime>(app: &tauri::AppHandle<R>) -> tauri::Result<()> {
    let quit_i = MenuItem::with_id(app, "quit", "退出", true, None::<&str>)?;
    let set_i = MenuItem::with_id(app, "set", "设置", true, None::<&str>)?;
    let show_i = MenuItem::with_id(app, "show", "显示窗口", true, None::<&str>)?;
    // 分割线
    let menu = Menu::with_items(app, &[&show_i, &set_i, &quit_i])?;

    let _ = TrayIconBuilder::with_id("tray")
        .icon(app.default_window_icon().unwrap().clone())
        .menu(&menu)
        .on_menu_event(move |app, event| match event.id.as_ref() {
            "show" => {
                for (key, value) in app.webview_windows() {
                    if key == "main" {
                        value.show().unwrap();
                    }
                }
            }
            "set" => {
                println!("set");
            }
            "quit" => {
                app.exit(0);
            }
            // Add more events here
            _ => {}
        })
        .on_tray_icon_event(|tray, event: TrayIconEvent| {
            if let TrayIconEvent::Click {
                button: MouseButton::Left,
                button_state: MouseButtonState::Up,
                ..
            } = event
            {
                let main_win=tray.app_handle().get_webview_window("main").unwrap();
                main_win.show().unwrap();
                main_win.unminimize().unwrap();
                main_win.set_focus().unwrap();
         
            }
        })
        .build(app);
    Ok(())
}

三 . 页面HTTP接口改造

1. 修改 Api hook 增加请求前缀

const res = await fetch(“http://localhost:8080” + url, options);

“http://localhost:8080” 为你的实际服务地址

这里要注意先修改权限配置如下：

 {
      "identifier": "http:default",
      "allow": [
        {
          "url": "http://**"
        },
        {
          "url": "https://**"
        },
        {
          "url": "http://*:*"
        },
        {
          "url": "https://*:*"
        }
      ],
      "deny": [
        {
          "url": "https://private.tauri.app"
        }
      ]
    },

2. 页面代码完善后如下

<template>

    <el-header>
      <el-col :span="8">
        <el-input v-model="queryInput" placeholder="请输入姓名搜索" />
