flask 处理css文件问题

Question

flask版本使用0.10版本。
文件结构：
/price
price.py
/templates
layout.html
index.html
rate.html
/static
style.css
这是我的python代码：
#-*-coding:utf-8-*-
fromflaskimportFlask,render_template
app=Flask(__name__)app.config.from_object(__name__)
app.config.from_envvar('FLASKR_SETTINGS',silent=True)
app.config.update(
#DATABASE='/flaskr.db',
DEBUG=True,
SECRET_KEY='freightprice',
USERNAME='admin',
PASSWORD='Jake'
)
@app.route("/")
defindex():
returnrender_template('index.html',page="index")
@app.route('/rate')
defrate():
returnrender_template('rate.html',page="rate")
@app.route('/update')
defupdate():
returnrender_template('update.html',page="update")
if__name__=='__main__':
app.run()
layout.html代码
{%blockbody%}{%endblock%}
访问CSS的时候出现以下错误：

css代码：
使用UTF-8编码保存

Answer 1

刚开始我也遇到了CSS不生效的情况，试着排查了下，发现我把app放在了带有中文字符的文件夹里，移到非中文字符文件夹里就能生效了。

Answer 2

看起來是常見的編碼問題,unicode跟string之間需要encode或decode的切換,可以看一下stacktrace找一下是哪裡有不是unicode的地方。
