问题描述

好像我的静态文件没有正确提供.这就是现在的样子:

Seems like my static files aren't being served properly. This is what it looks like right now:

myApp
    __init__.py
    static
       img
       js
         bootstrap.min.js
       etc.

这是我 __ init __.py 中的应用程序配置的样子:

This is what my app config in my __init__.py looks like:

app = Flask(__name__, static_url_path="", static_folder="static")

这是错误:

127.0.0.1 - - [01/Dec/2014 13:12:01] "GET /static/js/bootstrap.min.js HTTP/1.1" 404 -

就url路由而言，没有问题，本地主机的localhost/home路由，本地主机的localhost/contact路由等.但是找不到静态文件:(我缺少什么吗?

As far as the url routing goes, no problems there, localhost/home routes to home, localhost/contact routes to contact, etc. But static files aren't being found :( Am I missing something?

注意:我是在Mac(纯粹是本地主机)上托管该主机

NOTE: I'm hosting this on my Mac, purely local host

这是我的 __ init __.py 主要方法:

if __name__ == "__main__":
    app.run(host='0.0.0.0', debug=True)

运行方式:

python __init.py__

推荐答案

似乎您正在硬编码到静态文件URL.您告诉Flask在没有URL前缀的情况下为它们提供服务器-默认值为/static -但日志显示请求将发送至/static/js/bootstrap.min.js .模板文件中可能包含以下内容.

It looks like you are hardcoding to static file URLs. You tell Flask to server them with no URL prefix -- the default would have been /static -- but the log shows the request going to /static/js/bootstrap.min.js. You probably have something like the following in a template file.

<script src="/static/js/bootstrap.min.js"></script>

相反，您应该使用 url_for 为您创建URL.将以上更改为

Instead, you should use url_for to create the URL for you. Change the above to

<script src="{{ url_for('static', filename='js/bootstrap.min.js') }}"></script>

这将导致

<script src="/js/bootstrap.min.js"></script>
