【python3】酷狗音乐及评论回复下载

新年快乐，上班第一天分享一个python源码，功能比较简单，就是实现酷狗音乐的音乐文件（包含付费音乐）和所有评论回复的下载。

以 米津玄師 - Lemon 为例， 以下为效果图：

1、根据关键词搜索指定音乐，发现是下载是付费的

2、点击进入评论，可以看到有很多的评论，评论底下也有很多的回复

3、执行代码下载音乐、评论回复

3.1、输入关键词搜索音乐，根据歌曲名称和时长，选择目标歌曲，根据提示下载音乐文件

3.2、下载评论回复

3.3、下载结果，评论回复较多，作为例子只下载了一部分

最后附上源码：

import requests
import json

# 写到文档
def write(path, text):
    with open(path, 'a', encoding='utf-8') as f:
        f.write(text+'\n')

# 时间转换
def get_time(duration):
    second = duration % 60
    minuter = int(duration / 60)
    hour = int(minuter / 60)
    minuter = int(minuter % 60) if hour > 0 else minuter
    time = []
    for i in [hour, minuter, second]:
        i = str(i) '+str(i)
        time.append(i)
    return ':'.join(time)

# 下载音乐
def down(filehash):
    hash_url = "http://www.kugou.com/yy/index.php?r=play/getdata&hash={0}".format(filehash)
    hash_content = requests.get(hash_url).text
    dt = json.loads(hash_content)
    audio_name = dt['data']['audio_name']
    audio_url = dt['data']['play_url']
    with open(audio_name + ".mp3", "wb")as fp:
        fp.write(requests.get(audio_url).content)
    print("音乐下载完成：{0}".format(audio_name + ".mp3"))
