烧瓶：在开发中，我如何实现媒体资产的动态路由？ [英] Flask: In development, how can I achieve dynamic routing for media assets?

问题描述

我正在使用Flask开发一个简单的Web应用程序。

在文件/文件夹/子文件夹/资产[.pdf | .jpg]中有静态媒体资源（照片，PDF等）。但是我希望这些文件的URL看起来像这样： files / folder_subfolder_asset [.pdf | jpg] 。如您所见，真正的路径被编码在文件名中。

$ b对于每个图像，$ b

文件夹和子文件夹是不同的。有很多图像！ 在生产上，在服务器上，我将处理 NGINX ，我怎么能在开发 ？注意：在开发上，我使用 Flask run 来测试应用程序。如果我需要使用不同的东西，请咨询。

解决方案

您可以尝试使用（Application Objects或Blueprint Objects， $ b $ ul

/docs/0.12/api/rel =nofollow noreferrer> doc ）： static_url_path - 可以用来指定Web上静态文件的不同路径。默认是 static_folder 文件夹的名称。

static_folder 应该在 static_url_path 处提供静态文件。默认为应用程序根路径中的static文件夹。

例如：

您可以将 static_foler 设置为静态文件目录： / files / folder / subfolder / asset ， static_url_path 到 / files / folder_subfolder_asset ：

  from flask import烧瓶，请求，重定向，url_for 
 $ b app =烧瓶（__ name __，static_folder ='文件/文件夹/子文件夹/资产/'，static_url_path ='/ files / （），
 
 $ b @ app.route（'/'，methods = ['GET']）
 def root（）：
 return redirect（url_for（'static'， filename ='figure.jpeg'））
 
 if __name__ =='__main__'：
 app.run（debug = True）
  pre> 
 
 
然后当你去 http://127.0.0.1:5000 时，它会重定向到 http://127.0.0.1:5000/files/folder_subfolder_asset/figure.jpeg ， url 更改为定义的那个在 sta tic_url_path  
 
I am using Flask to develop a simple web application. 

I have static media assets (photographs, PDFs etc) inside files/folder/subfolder/asset[.pdf|.jpg]. But I want the URL to the files to look like this: files/folder_subfolder_asset[.pdf|jpg]. As you can see, the real path is coded in the filename.

folder and subfolder are different for each image. There are a lot of images! 

On production, on the server, I will be handling the serving of the files with NGINX, how can I accomplish something similar on development? 

Note: on development I'm using Flask run to test the application. Please advice if I need to use something different. 
解决方案
You could try with (Application Objects or Blueprint Objects, doc) :


static_url_path – can be used to specify a different path for the static files on the web. Defaults to the name of the static_folder folder.
static_folder – the folder with static files that should be served at static_url_path. Defaults to the 'static' folder in the root path of the application.


eg:

Your could set static_foler to static file directory: /files/folder/subfolder/asset, and static_url_path to /files/folder_subfolder_asset:
from flask import Flask, request, redirect, url_for

app = Flask(__name__,static_folder='files/folder/subfolder/asset/', static_url_path='/files/folder_subfolder_asset')

@app.route('/', methods=['GET'])
def root():
    return redirect(url_for('static', filename='figure.jpeg'))   

if __name__ == '__main__':
    app.run(debug=True)
Then when you go to http://127.0.0.1:5000, it will redirect to http://127.0.0.1:5000/files/folder_subfolder_asset/figure.jpeg, the url was change to the one defined in static_url_path
