blocks|key|1085030|text|为静态文件提供服务与旨在提供动态内容的应用程序无关。提供静态文件的正确方式取决于您使用的服务器。毕竟，当您的应用程序启动并运行时，您将需要将其绑定到web服务器。我只能代表apache+httpd发言，所以提供静态文件的方式是在通过mod-wsgi绑定到应用程序的虚拟主机中定义的。下面的指南将向您展示如何为站点地图、robots.txt或任何静态内容提供服务：http://code.google.com/p/modwsgi/wiki/QuickConfigurationGuide#Mounting_At_Root_Of_Site|type|unstyled|depth|inlineStyleRanges|entityRanges|offset|length|data|1085031|entityMap|0|LINK|mutability|MUTABLE|url|http://code.google.com/p/modwsgi/wiki/QuickConfigurationGuide#Mounting_At_Root_Of_Site^0|51|2E|0|0^^$0|@$1|2|3|4|5|6|7|L|8|@]|9|@$A|M|B|N|1|O]]|C|$]]|$1|D|3|-4|5|6|7|P|8|@]|9|@]|C|$]]]|E|$F|$5|G|H|I|C|$J|K]]]]

Serving static files has nothing to do with application that is meant to deliver dynamic content. The correct way of serving static files is dependent of what server you're using. After all, when you get your app up and running, you will need to bind it to a web server. I can speak only for apache httpd, so the way of serving static files is defined in the virtual host that you are binding to your application through mod-wsgi. Here is the guide that will show you how to serve sitemaps, robots.txt or any static content:

blocks|key|1085108|text|@vonPetrushev是对的，在生产中，你会希望通过nginx或apache提供静态文件，但对于开发来说，拥有简单的开发环境是很好的，让你的python应用程序提供静态内容，这样你就不必担心更改配置和多个项目。要做到这一点，您需要使用SharedDataMiddleware。|type|unstyled|depth|inlineStyleRanges|entityRanges|offset|length|data|1085109|from+flask+import+Flask

@vonPetrushev is right, in production you'll want to serve static files via nginx or apache, but for development it's nice to have your dev environment simple having your python app serving up the static content as well so you don't have to worry about changing configurations and multiple projects. To do that, you'll want to use the <a href="http://werkzeug.pocoo.org/docs/middlewares/#werkzeug.wsgi.SharedDataMiddleware" rel="noreferrer">SharedDataMiddleware</a>.

<pre><code>from flask import Flask
app = Flask(__name__)
'''
Your app setup and code
'''
if app.config['DEBUG']:
 from werkzeug import SharedDataMiddleware
 import os
 app.wsgi_app = SharedDataMiddleware(app.wsgi_app, {
 '/': os.path.join(os.path.dirname(__file__), 'static')
 })
</code></pre>

This example assumes your static files are in the folder "static", adjust to whatever fits your environment.

blocks|key|1085158|text|这可能是在提出这个问题后添加的，但我在查找flask的"helpers.py“时发现了flask.send_from_directory：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1085159|send_from_directory(directory,+filename,+**options)

This might have been added since this question was asked, but I was looking through flask's "helpers.py" and I found flask.send_from_directory:

<pre><code>send_from_directory(directory, filename, **options)
'''
 send_from_directory(directory, filename, **options)
 Send a file from a given directory with send_file. This
 is a secure way to quickly expose static files from an upload folder
 or something similar.
'''
</code></pre>

... which references flask.send_file:

<pre><code>send_file(filename_or_fp, mimetype=None, as_attachment=False, attachment_filename=None, add_etags=True, cache_timeout=43200, conditional=False)
</code></pre>

... which seems better for more control, although send_from_directory passes **options directly through to send_file.

blocks|key|1085244|text|另一种发送静态文件的方法是使用如下所示的通用规则：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1085245|@app.route('/<path:path>')

Another way to send static files is to use a catch-all rule like this:

<pre><code>@app.route('/&lt;path:path&gt;')
def catch_all(path):
 if not app.debug:
 flask.abort(404)
 try:
 f = open(path)
 except IOError, e:
 flask.abort(404)
 return
 return f.read()
</code></pre>

I use this to try to minimise the set-up when developing. I got the idea from <a href="http://flask.pocoo.org/snippets/57/" rel="noreferrer">http://flask.pocoo.org/snippets/57/</a>

Further, I'm developing using flask on my standalone machine but deploying with Apache in production server. I use:

<pre><code>file_suffix_to_mimetype = {
 '.css': 'text/css',
 '.jpg': 'image/jpeg',
 '.html': 'text/html',
 '.ico': 'image/x-icon',
 '.png': 'image/png',
 '.js': 'application/javascript'
}
def static_file(path):
 try:
 f = open(path)
 except IOError, e:
 flask.abort(404)
 return
 root, ext = os.path.splitext(path)
 if ext in file_suffix_to_mimetype:
 return flask.Response(f.read(), mimetype=file_suffix_to_mimetype[ext])
 return f.read()

[...]

if __name__ == '__main__':
 parser = optparse.OptionParser()
 parser.add_option('-d', '--debug', dest='debug', default=False,
 help='turn on Flask debugging', action='store_true')

 options, args = parser.parse_args()

 if options.debug:
 app.debug = True
 # set up flask to serve static content
 app.add_url_rule('/&lt;path:path&gt;', 'static_file', static_file)
 app.run()
</code></pre>

blocks|key|1085316|text|尽管这是一个老生常谈的问题，但我之所以回答这个问题，是因为这篇文章在谷歌搜索结果中占据了相当高的位置。虽然文档中没有对其进行介绍，但如果您阅读了Flask+Application对象构造函数的the+API+docs，就会对其进行介绍。通过像这样传递命名参数static_folder：|type|unstyled|depth|inlineStyleRanges|offset|length|style|CODE|entityRanges|data|1085317|from+flask+import+Flask

Even though this is an old answered question, I'm answering this because this post comes up pretty high in the Google results. While it's not covered in the documentation, if you read <a href="http://flask.pocoo.org/docs/api/#api" rel="noreferrer">the API docs</a> for the Flask Application object constructor it's covered. By passing the named parameter <code>static_folder</code> like so:

<pre><code>from flask import Flask
app = Flask(__name__,
 static_folder="/path/to/static",
 template_folder="/path/to/templates")
</code></pre>

...you can define where static files are served from. Similarly, you can define a <code>template_folder</code>, the name of you <code>static_url_path</code>.

blocks|key|870512|text|试试这个：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|870513|@app.route("/ProtectedFolder/<path:filename>")

<pre><code>@app.route(&quot;/ProtectedFolder/&lt;path:filename&gt;&quot;)
@CheckUserSecurityAccessConditions
def Protect_Content(filename):
 return send_from_directory((os.path.join(os.path.dirname(__file__), 'ProtectedFolder')),filename)
</code></pre>

Is there any clever solution to store static files in Flask's application root directory.
robots.txt and sitemap.xml are expected to be found in /, so my idea was to create routes for them:

<pre><code>@app.route('/sitemap.xml', methods=['GET'])
def sitemap():
 response = make_response(open('sitemap.xml').read())
 response.headers["Content-type"] = "text/plain"
 return response
</code></pre>

There must be something more convenient :)
