我正在使用Python Flask。我想通过权限检查向用户发送媒体文件（mp4，mp3，mov等）。我将检查用户对DB的权限，我想只为经过身份验证的用户发送文件。
所以我开始开发该系统。我使用登录检查权限，我使用Send_file将文件发送给用户。在桌面上，它运作良好。但在我的iPad，iPhone，Android手机上，它没有用。他们的播放器警报“无法播放此视频”。在iPhone中，播放器的播放按钮不可用。

Flask服务器（Gunicorn）回归
“错误：[Errno 107]传输端点未连接”。当python烧瓶调试服务器 - “错误：[错误32]管道损坏。
我在超过5个不同的服务器上测试过，但它仍然无法正常工作。
我还使用了x-sendfile或send_from_directory，手动构建响应头。
@app.route('/download/<path:filename>')
def download(filename):
return send_file('data/file/' + filename)
在iOS7，iOS6，android中请求视频时，Gunicorn Flask Server出错

我终于解决了这个问题。
首先，我正在使用Nginx和Gunicorn。
使用Nginx和Gunicorn时，您可以使用以下步骤在下载文件之前检查身份验证信息。
它使用的是Nginx内部重定向功能。它将阻止对您的文件进行未经身份验证的访问。
用户 - > Nginx - > Gunicorn - >在python代码中检查Auth信息 - >响应数据
server {
listen 80;
server_name yourserver.com;
location /download_file/ {
internal; # Receive just internal redirect
alias /file/path/in/your/server/;
}
# Just for Gunicorn Serving (option)
location / {
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_set_header Host $http_host;
proxy_redirect off;
if (!-f $request_filename) {
proxy_pass http://service;
break;
}
}
}
@app.route('/download/<path:filename>')
def download(filename):
if not authentication():
abort(404)
redirect_path = '/download_file/' + filename
response = make_response("")
response.headers["X-Accel-Redirect"] = redirect_path
response.headers["Content-Type"] = mimetypes.guess_type(filename)
return response
然后您的浏览器将从Nginx接收文件
在iOS中工作也喜欢从常见的Web服务器提供服务。
