tkinter懒人音乐下载器

以下是一个简单的Tkinter懒人音乐下载器的示例代码，它使用Python的requests库和BeautifulSoup库来从网上搜索和下载音乐。请注意，这只是一个示例，可能不适用于所有网站和音乐类型。

import requests
from bs4 import BeautifulSoup
import tkinter as tk
from tkinter import messagebox, filedialog

def search_music():
    query = entry.get()
    if not query:
        messagebox.showerror("Error", "Please enter a search query.")
        return

    url = "https://www.youtube.com/results?search_query=" + query
    response = requests.get(url)
    soup = BeautifulSoup(response.text, "html.parser")

    videos = soup.select(".yt-uix-tile-link")
    if not videos:
        messagebox.showerror("Error", "No videos found.")
        return

    video = videos[0]
    video_url = "https://www.youtube.com" + video["href"]

    response = requests.get(video_url)
    soup = BeautifulSoup(response.text, "html.parser")

    audio = soup.select(".audio-thumb")
    if not audio:
        messagebox.showerror("Error", "No audio found.")
        return

    audio_url = audio[0]["href"]
    download_music(audio_url)

def download_music(url):
    filepath = filedialog.asksaveasfilename(defaultextension=".mp3")
    if not filepath:
        return

    response = requests.get(url)
    with open(filepath, "wb") as f:
        f.write(response.content)

root = tk.Tk()
root.title("Lazy Music Downloader")

label = tk.Label(root, text="Enter a search query:")
label.pack()

entry = tk.Entry(root, width=50)
entry.pack()

button = tk.Button(root, text="Search", command=search_music)
button.pack()

root.mainloop()

在这个示例中，我们首先使用requests库从YouTube搜索音乐，然后使用BeautifulSoup库从搜索结果中提取视频和音频的URL。最后，我们使用filedialog库提供的对话框来选择文件路径并下载音乐。
