python - CherryPy URL 映射不起作用

Question

我正在尝试使 URL 映射正常工作，但到目前为止还无法实现。我正在附加 config.conf、global.conf 和 server.py 文件，请帮忙。

我已经阅读了有关调度的 CherryPy 文档，但我就是不知道我可能在哪里做错了。我是 CherryPy 的新手。

我收到以下错误:

404 Not Found

The path '/titles.html' was not found.
In addition, the custom error page failed: 
ValueError: unsupported format character '"' (0x22) at index 1916

from jinja2 import Environment, FileSystemLoader

HTTP_ROOT = os.path.abspath(os.path.dirname(__file__))
env       = Environment(loader=FileSystemLoader(os.path.join(HTTP_ROOT,'templates')))

conf = os.path.join(HTTP_ROOT,'config.conf')
glob = os.path.join(HTTP_ROOT,'global.conf')

class Root(object):
    @cherrypy.expose
    def index(self):
        tmpl = env.get_template('index.html')
        return tmpl.render(title='CherryPy - Pythonic WSGI OO HTTP WEB Framework')

@cherrypy.expose
def titles(self):
    today = date.today()
    tmpl = env.get_template('titles.html')
    return tmpl.render(launch1=(date(2014,2,18)-today).days)


root = Root()
root.titles = titles

if __name__ == '__main__':
    cherrypy.config.update(glob)
    cherrypy.tree.mount(root, "/", config=conf)
    cherrypy.engine.start()
    cherrypy.engine.block()

你的标题句柄就是这样。

http://localhost/titles

不需要 .html。这仅与模板系统的物理路径相关。不过如果你真的做了什么可以引用:

http://localhost/titles.html

然后将你的句柄更改为此...

@cherrypy.expose
def titles_html(self):
    today = date.today()
    tmpl = env.get_template('titles.html')
    return tmpl.render(launch1=(date(2014,2,18)-today).days)
