【平头哥RVB2601创意应用开发】MP3播放器 [复制链接]

项目目的：1、在本地建立音乐播放服务器。

                  2、RVB2601连接路由器

                  3、播放本地的歌曲

一、用python建立自己的服务器：

      本项目用python的tornado建立音乐播放服务器：

     1、环境为python3+pycharm。具体如何安装，可自行网上找例程。因为不是本帖的重点，如果有需要可以单独联系我哈。

     服务器源码如下，就是23行，简单吧：

#!/usr/bin/env python
# -*- coding:utf-8 -*-

import os
import tornado.ioloop
import tornado.web


class MainHandler(tornado.web.RequestHandler):
    def get(self, filename):
        self.set_header('Content-Type', 'audio/mpeg')
        if os.path.exists(filename):
            with open(filename, 'rb') as f:
                while True:
                    data = f.read(1024)
                    if not data:
                        break
                    self.write(data)
            self.finish()
        else:
            self.send_error(404)


def make_app():
    return tornado.web.Application([
        (r"/(.*)", MainHandler),
    ])


if __name__ == "__main__":
    app = make_app()
    app.listen(8888)
    tornado.ioloop.IOLoop.current().start()

启动服务器后，在自己浏览器上测试：

 OK可以播放了。

二、打开CDK，下载web_play例程到本地：

修一个地方，让RVB2601可以自己上网：

 大家注意一定要指定ssd 跟pwd的长度，要不死活连不上网，我因为这个弄了好久。

netmgr_config_wifi(app_netmgr_hdl, "you ssid", strlen("you ssid"), "you passwd", strlen("youpasswd"));

  然后编译下载就OK了！

重启后看到连到wifi是否连上网：

 然后输入播放命令：

player play http://192.168.3.192:8888/2.mp3，就可以播放音乐了：

如果加上几个按键，就可以实现播放、停止、下一首了。

但是就是这喇叭的功率太了，大家要用缓冲的垫一下，把翻过来听，要不如果正面放，到低音时会有杂音。

总的来说，RVB是功能是非常强大的，还有很多的东西需要不断的去学习，在这里非常感谢坛友们，我是从他们的作品中学习到如何使用RVB2601。期待大家共同进步。
