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.path

from flask import Flask, Response


app = 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: …

我有一个通过端口5000运行的Flask服务器,它很好.我可以访问http://example.com:5000

但是可以在http://example.com上简单地访问它吗？我假设这意味着我必须将端口从5000更改为80.但是当我在Flask上尝试时,我在运行它时收到此错误消息.

Traceback (most recent call last):
  File "xxxxxx.py", line 31, in <module>
app.run(host="0.0.0.0", port=int("80"), debug=True)
   File "/usr/local/lib/python2.6/dist-packages/flask/app.py", line 772, in run
run_simple(host, port, self, **options)

socket.error: [Errno 98] Address already in use

运行lsof -i :80回报
