首选方法是使用nginx或其他Web服务器提供静态文件。他们将比Flask更有效率。
但是，你可以用来
send_from_directory从目录发送文件，这在某些情况下非常方便：
from flask import Flask, request, send_from_directory# set the project root directory as the static folder, you can set others.app = Flask(__name__, static_url_path='')@app.route('/js/<path:path>')def send_js(path): return send_from_directory('js', path)if __name__ == "__main__": app.run()千万不能使用
send_file或
send_static_file与用户提供的路径。
send_static_file 例：from flask import Flask, request# set the project root directory as the static folder, you can set others.app = Flask(__name__, static_url_path='')@app.route('/')def root(): return app.send_static_file('index.html')
