如何在Flask中提供静态文件
所以这很尴尬。我有一个应用程序,我把它放在一起,Flask
现在它只是提供一个静态HTML页面,其中包含一些CSS和JS的链接。我无法在文档Flask
中找到返回静态文件的位置。是的,我可以使用,render_template
但我知道数据没有模板化。我曾经想过send_file
或者url_for
是对的,但是我无法让它们发挥作用。与此同时,我正在打开文件,阅读内容,并Response
使用适当的mimetype来装配:
import os.pathfrom flask import Flask, Responseapp = Flask(__name__)app.config.from_object(__name__)def root_dir(): # pragma: no cover return os.path.abspath(os.path.dirname(__file__))def get_file(filename): # pragma: no cover try: src = os.path.join(root_dir(), filename) # Figure out how flask returns static files # Tried: # - render_template # - send_file # This should not be so non-obvious return open(src).read() except IOError as exc: return str(exc)@app.route('/', methods=['GET'])def metrics(): # pragma: no cover content = get_file('jenkins_analytics.html') return Response(content, mimetype="text/html")@app.route('/', defaults={'path': ''})@app.route('/<path:path>')def get_resource(path): # pragma: no cover mimetypes = { ".css": "text/css", ".html": "text/html", ".js": "application/javascript", } complete_path = os.path.join(root_dir(), path) ext = os.path.splitext(path)[1] mimetype = mimetypes.get(ext, "text/html") content = get_file(complete_path) return Response(content, mimetype=mimetype)if __name__ == '__main__': # pragma: no cover app.run(port=80)
有人想为此提供代码示例或网址吗?我知道这很简单。
