我使用Flask和send_file()
让人们从服务器下载文件。
我目前的代码如下:
@app.route('/', methods=["GET", "POST"])
def index():
if request.method == "POST":
link = request.form.get('Link')
with youtube_dl.YoutubeDL(ydl_opts) as ydl:
info_dict = ydl.extract_info(link, download=False)
video_url = info_dict.get("url", None)
video_id = info_dict.get("id", None)
video_title = info_dict.get('title', None)
ydl.download([link])
print("sending file...")
send_file("dl/"+video_title+".f137.mp4", as_attachment=True)
print("file sent, deleting...")
os.remove("dl/"+video_title+".f137.mp4")
print("done.")
return render_template("index.html", message="Success!")
else:
return render_template("index.html", message=message)
我添加.f137.mp4
的唯一原因是,我使用AWS C9作为我的在线IDE,并且我无法在Amazon Linux上安装FFMPEG来组合音频和视频。然而,这不是问题所在。问题是它没有发送下载请求。
以下是控制台输出:
