Django實(shí)現(xiàn)在線無水印抖音視頻下載(附源碼及地址)
更新時(shí)間：2021年05月06日 15:17:06 作者：大江狗
該項(xiàng)目功能簡單，完全復(fù)制SaveTweetVedio的項(xiàng)目。用戶觀看抖音視頻時(shí)選擇復(fù)制視頻鏈接，輸入到下載輸入欄，即可下載無水印視頻，還可掃描二維碼手機(jī)上預(yù)覽。親測成功。
項(xiàng)目地址是：https://www.chenshiyang.com/dytk
接下來我們分析下源碼簡要看下實(shí)現(xiàn)原理。
實(shí)現(xiàn)原理
該項(xiàng)目不需要使用模型(models), 最核心的只有兩個(gè)頁面：一個(gè)主頁面(home)展示包含下載url地址的表單，一個(gè)下載頁面(download)處理表單請求，并展示去水印后的視頻文件地址及文件大小，以及用于手機(jī)預(yù)覽的二維碼。
對(duì)應(yīng)兩個(gè)核心頁面的路由如下所示，每個(gè)url對(duì)應(yīng)一個(gè)視圖函數(shù)。
# urls.py
from django.urls import path
from web.views import home, download
urlpatterns = [
path('home', home),
path('downloader', download),
]
#web/urls.py
from django.http import HttpResponse
from django.shortcuts import render, redirect
# Create your views here.
from common.utils import format_duration, load_media
from common.DouYin import DY
def home(request):
"""首頁"""
return render(request, 'home.html')
def download(request):
"""下載"""
url = request.POST.get('url', None)
assert url != None
dy = DY()
data = dy.parse(url)
mp4_path, mp4_content_length = load_media(data['mp4'], 'mp4')
mp3_path, mp3_content_length = load_media(data['mp3'], 'mp3')
realpath = ''.join(['https://www.chenshiyang.com', mp4_path])
print('realpath---------------------', realpath)
if len(data['desc'].split('#')) > 2:
topic = data['desc'].split('#')[2].rstrip('#')
return render(request, 'download.html', locals())
可以看出通過home頁面表單提交過來的下載url會(huì)交由download函數(shù)處理。common模塊的DouYin.py中定義的DY類負(fù)責(zé)對(duì)url繼續(xù)解析，爬取相關(guān)視頻地址，通過自定義utils.py中的load_media方法下載文件，并返回文件路徑以及文件大小。
由于解析下載url，從抖音爬取數(shù)據(jù)的代碼都封裝到DY類里了，所以我們有必要貼下這個(gè)類的代碼。另外，我們還需要貼下load_media這個(gè)方法的代碼。

data['mp3'] = mp3
data['mp4'] = mp4
data['cover'] = cover
data['nickname'] = author
data['desc'] = desc
data['duration'] = format_duration(item.get("duration"))
return data
從代碼你可以看到返回的data字典里包括了mp3和mp4源文件地址，以及視頻的封面，作者昵稱及描述等等。
接下來你可以看到load_media方法爬取了視頻到本地，并提供了新的path和大小。
