Setting up static folder path in Flask
提问by Stupid.Fat.Cat
Seems like my static files aren't being served properly. This is what it looks like right now:
似乎我的静态文件没有正确提供。这是它现在的样子：
myApp
__init__.py
static
img
js
bootstrap.min.js
etc.
This is what my app config in my __init__.pylooks like:
这是我的应用程序配置的__init__.py样子：
app = Flask(__name__, static_url_path="", static_folder="static")
This is the error:
这是错误：
127.0.0.1 - - [01/Dec/2014 13:12:01] "GET /static/js/bootstrap.min.js HTTP/1.1" 404 -
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?
就 url 路由而言，那里没有问题，本地主机/家庭路由到家，本地主机/联系人路由联系等。但是没有找到静态文件:(我错过了什么吗？
NOTE: I'm hosting this on my Mac, purely local host
注意：我在我的 Mac 上托管这个，纯本地主机
This is my __init__.pymain method:
这是我的__init__.py主要方法：
if __name__ == "__main__":
app.run(host='0.0.0.0', debug=True)
Running as:
运行为：
python __init.py__

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.
看起来您正在硬编码到静态文件 URL。您告诉 Flask 以不带 URL 前缀的方式为它们提供服务——默认是这样/static——但日志显示请求将转到/static/js/bootstrap.min.js。您可能在模板文件中有如下内容。
<script src="/static/js/bootstrap.min.js"></script>
Instead, you should use url_forto create the URL for you. Change the above to
相反，您应该使用url_for为您创建 URL。把上面的改成
<script src="{{ url_for('static', filename='js/bootstrap.min.js') }}"></script>
This will result in
这将导致
<script src="/js/bootstrap.min.js"></script>
