基于python实现在线听音乐（QQ音乐）

在CSDN中，许多的听音乐代码是在用户已有一个音乐的MP3文件的情况下实现自动播放音频。接下来的代码可以实现你说什么音乐，他就放什么音乐。

首先我们来分析一下实现这个功能分为那几步骤。

用户输入歌名/歌手——>自动上网查询——>自动保存到pythonproject文件——>自动打开保存文件

这些步骤我们可以进行归纳为两部分：保存目标歌曲、打开保存文件

保存目标歌曲代码：

    music_json = response[9:-1]
    # json转字典
    music_data = json.loads(music_json)  # 转换成 字典
    # print(music_data)
    music_list = music_data['data']['song']['list']
    for music in music_list:
        music_name = music['songname']  # 歌曲的名字
        singer_name = music['singer'][0]['name']  # 歌手的名字
        songmid = music['songmid']

        purl = response['req_0']['data']['midurlinfo'][0]['purl']
        full_media_url = 'http://dl.stream.qqmusic.qq.com/' + purl
        music_data.append(
            {
                'music_name': music_name,
                'singer_name': singer_name,
                'full_media_url': full_media_url
            })
    return music_data
def save_music_mp3(music_data):
    """下载歌曲"""
    if not os.path.exists('歌曲下载'):
        os.mkdir('歌曲下载')
    for music in music_data:
        music_name = music['music_name']
        singer_name = music['singer_name']
        full_url = music['full_media_url']
        music_response = requests.get(full_url, headers=headers).content       #歌曲下载
        with open('歌曲下载/%s-%s.mp3' % (music_name, singer_name), 'wb')as fp:
            fp.write(music_response)
            print('[%s]保存成功！' % music_name)    #成功反馈


if __name__ == '__main__':
    music_info_list = get_music_info()
    music_data = get_purl(music_info_list)
    save_music_mp3(music_data)

通过这段代码可以把音乐保存到一个叫“歌曲下载” 的文件中

那么如何把保存的文件自动打开呢？我们可以用Chromedriver打开

打开保存歌曲代码：

    for music in music_data:
        music_name = music['music_name']
        singer_name = music['singer_name']
        x = (music_name + "-" + singer_name)
        print(x)   #变量x就是我们刚刚那段代码保存下来的音乐名
        # coding = utf-8
        from time import sleep
        import os
        from selenium import webdriver

       

        browser = webdriver.Chrome()
        # browser.get('http://www.baidu.com/')
        browser.get('file:///D:/PycharmProjects/pythonProject2/歌曲下载/'+ x + ".mp3") #路径可以自行修改

        login_form = browser.find_element_by_id('auto').click()

        # 等待5秒
        sleep(10 * 60)
        # 退出
        browser.quit()

最终代码：
