用 Python 將歌單里的歌詞保存成圖片

還有缺陷需要彌補

GitHub - songzhi/Lrc2Img: 用Python將歌單里的所有歌曲的歌詞保存成圖片，使用了網易雲音樂API

使用了：

• 網易雲音樂的API
• Pillow，requests 等模塊

• 字體是 造字工房尚黑常規體，可以自己更改，在Img類里的save方法的font變數里

大概思路：

1.利用 API 獲取信息，返回的是 Json 格式的數據，可以使用標準庫里的 json 模塊轉化成Python 內建的數據結構，其中 Json 中的 Object 轉化成了列表，所以對其進行迭代，找出其中的專輯圖片（url）、歌曲名字 id 和歌詞分別放入幾個列表中。

class NetEase(): cookies_filename = "netease_cookies.json" def __init__(self): super().__init__() self.headers = { Host: music.163.com, Connection: keep-alive, Content-Type: "application/x-www-form-urlencoded; charset=UTF-8", Referer: http://music.163.com/, "User-Agent": "Mozilla/5.0 (Macintosh; Intel Mac OS X 10_9_2) AppleWebKit/537.36" " (KHTML, like Gecko) Chrome/33.0.1750.152 Safari/537.36" } self.cookies = dict(appver="1.2.1", os="osx") def show_progress(self, response): content = bytes() total_size = response.headers.get(content-length) if total_size is None: content = response.content return content else: total_size = int(total_size) bytes_so_far = 0 for chunk in response.iter_content(): content += chunk bytes_so_far += len(chunk) progress = round(bytes_so_far * 1.0 / total_size * 100) self.signal_load_progress.emit(progress) return content def http_request(self, method, action, query=None, urlencoded=None, callback=None, timeout=1): headers={ Host: music.163.com, Connection: keep-alive, Content-Type: "application/x-www-form-urlencoded; charset=UTF-8", Referer: http://music.163.com/, "User-Agent": "Mozilla/5.0 (Macintosh; Intel Mac OS X 10_9_2) AppleWebKit/537.36" " (KHTML, like Gecko) Chrome/33.0.1750.152 Safari/537.36" } cookies = dict(appver="1.2.1", os="osx") res = None if method == "GET": res = requests.get(action, headers=headers, cookies=cookies, timeout=timeout) elif method == "POST": res = requests.post(action, query, headers=self.headers, cookies=self.cookies, timeout=timeout) elif method == "POST_UPDATE": res = requests.post(action, query, headers=self.headers, cookies=self.cookies, timeout=timeout) self.cookies.update(res.cookies.get_dict()) self.save_cookies() content = self.show_progress(res) content_str = content.decode(utf-8) content_dict = json.loads(content_str) return content_dict def user_playlist(self, uid): action = http://music.163.com/api/playlist/detail?id= + str(uid) res_data = self.http_request(GET, action) return res_data def get_lyric_by_musicid(self, mid): url = http://music.163.com/api/song/lyric? + id= + str(mid) + &lv=1&kv=1&tv=-1 return self.http_request(GET, url)

2.定義一個 Playlist 類：

class Playlist(): def __init__(self,uid): self.id=uid def get(self): uid=self.id import re music=NetEase() playlist = music.user_playlist(uid=uid) self.playlist = playlist[result][tracks] self.songName = [] self.songId = [] self.songImg = [] self.songLrc = [] for song in self.playlist: self.songName.append(song["name"]) self.songId.append(song["id"]) self.songImg.append(song["album"]["blurPicUrl"]) for songid in self.songId: lrc = music.get_lyric_by_musicid(mid=songid) lrc=lrc[lrc][lyric] pat = re.compile(r[.*]) lrc = re.sub(pat, "", lrc) lrc=lrc.strip() self.songLrc.append(lrc) def createImg(self): img=Img() for songName,songLrc,songImg in zip(self.songName,self.songLrc,self.songImg): img.save(songName,songLrc,songImg)

3.定義一個 Img 類來操作圖片：

class Img(): def __init__(self): import os try: self.Path = rC:Img self.albumImgPath = self.Path + ralbumImg os.mkdir(self.Path) os.mkdir(self.albumImgPath) except: pass return def getsize(self,lrc): lrc=lrc.split(
) width = [] for line in lrc: width.append(len(line)) width = max(width) self.fontSize = 500//width-1 # 字體大小 fontSpace = 10 # 每行間隔大小 length=len(lrc)*(self.fontSize+fontSpace) return width,length def save(self,name,lrc,imgurl): from io import BytesIO import requests width, length = self.getsize(lrc) from PIL import Image, ImageDraw, ImageFont albumImgSize=500#專輯縮略圖大小 font="MFShangHei_Noncommercial-Regular.otf" fontSize=self.fontSize#字體大小 fontSpace=10#每行間隔大小 space=10#留白 rImg= requests.get(imgurl) albumImg = Image.open(BytesIO(rImg.content)) albumImg.save(self.albumImgPath+r\+name + .bmp) font=ImageFont.truetype(font, fontSize) rSizeImg=albumImg.resize((albumImgSize,albumImgSize),resample=3) x=albumImgSize y=albumImgSize+length+space*4 outImg=Image.new(mode=RGB, size=(x, y), color=(255, 255, 255)) draw= ImageDraw.Draw(outImg) outImg.paste(rSizeImg,(0,0)) draw.text((space*2,albumImgSize+space*2),lrc,font=font,fill=(0,0,0),spacing=fontSpace,align=left) draw.text((space*2, y-80),——+name,fill=(0,0,0),font=font,align=left) outImg.save(self.Path+r\+name+.bmp) return

4.最後調用：

id=input(請輸入歌單ID：)music=Playlist(id)music.get()music.createImg()
