Question

编辑：完全忽略此问题。这是一个文件系统问题。

每当我尝试打开posts文件夹时，都会收到错误消息：

Traceback (most recent call last):
  File "C:\Python36-32\lib\site-packages\flask\app.py", line 1997, in __call__
    return self.wsgi_app(environ, start_response)

    with open(str(find_recent_post_name())) as post:
PermissionError: [Errno 13] Permission denied: 'posts/'

我的main.py文件：

from flask import Flask
from flask import render_template

app = Flask(__name__)

def find_recent_post_name():
    import glob
    posts = glob.glob("posts/")
    return posts[len(posts) - 1]

def find_recent_post():
    with open(str(find_recent_post_name())) as post:
        newest_post = post.readlines()
    return newest_post


@app.route("/")
def index():
    return render_template("index.html", newest_post=find_recent_post())

if __name__ == '__main__':
    app.run(debug=True)

我的Python版本是v3.6.1和Flask v1.12.0

编辑：调试代码并使用PowerShell似乎有效。

烧瓶不是问题。您可以更改文件夹/posts/的权限，也可以以read访问权限的用户身份运行flask。

$ chmod 755 <folder names>

允许访问运行烧瓶应用的用户，或者您可以使用：

$ sudo python main.py

作为admin运行或以已有访问权限的用户身份运行flask。并注意您应该在部署时添加相同的设置。因此uwsgi或gunicron的工作人员或者您在部署时运行应用程序的工作人员应使用相同的凭据运行。

请注意，您的user应具有read或4访问权限，以便阅读文件内容并获得execute或1访问权限能够cd进入它。

使用Flask访问Python3.6上的文件夹的权限被拒绝
