tornado总结4-html模板使用2_html/css_WEB-ITnose
参考地址
http://www.tornadoweb.org/en/stable/guide/templates.html?highlight=render#ui-modules
osc的所有页面顶部都有这个导航条, 我们可以使用tornado的UI modules来实现导航条,实现代码的复用.
增加了一个my_uimodules.py,里面包含了供tornado模板使用的uimodules,增加了一个header.html里面是导航条的html代码,增加了一个page2.py,返回简单的html页面page2.html.
访问路径 "/"时的效果
点击导航链接 "页面1"的效果
点击导航链接 "页面2"的效果
my_uimodules.py
import tornado.webclass HeaderBar(tornado.web.UIModule): def render(self, location): return self.render_string("header.html", location=location)class HeaderBar2(tornado.web.UIModule): def render(self, location): return self.render_string("header.html", location=location)所有的模板驱动都继承自 tornado.web.UIModule , 然后调用render_string调用指定的模板和参数. 你可以在此处写一个顶部导航栏再写个侧边导航栏. 我只在这里写了一个顶部导航模板驱动. 它接受一个参数location, 我把它作为导航栏最右侧的页面说明. 本模板驱动返回的是header.html,并把location传给了它.
header.html
<div> <a href="/">主页</a> <a href="/page1">页面1</a> <a href="/page2">页面2</a> <span>你现在处于页面 {{ location }}</span></div> 本模板文件作为页面的顶部导航栏,并通过location参数得到当前的页面地址
main.py
import osimport tornado.httpserverimport tornado.ioloopimport tornado.webimport my_uimodulesfrom handlers.home import HomeHandlerfrom handlers.page1 import Page1Handlerfrom handlers.page2 import Page2Handlerclass PageNotFoundHandler(tornado.web.RequestHandler): def get(self): return self.write_error(404)class Application(tornado.web.Application): def __init__(self): handlers = [ (r"/", tornado.web.RedirectHandler, {"url": "/home"}), (r"/home", HomeHandler), (r"/page1", Page1Handler), (r"/page2", Page2Handler), (r".*", PageNotFoundHandler), ] settings = dict( static_path= os.path.join(os.path.dirname(__file__), "static"), template_path=os.path.join(os.path.dirname(__file__), "templates"), ui_modules=my_uimodules, ) tornado.web.Application.__init__(self, handlers, **settings)if __name__ == "__main__": port = 8899 application = Application() http_server = tornado.httpserver.HTTPServer(application, xheaders=True) http_server.listen(port) print('Listen on http://localhost:{0}'.format(port)) print('Listen on http://localhost:{0}/page1'.format(port)) print('Listen on http://localhost:{0}/page2'.format(port)) tornado.ioloop.IOLoop.instance().start()在torndao进行初始化设置时, 在settings 里面指定了自定义模板所在模块.
"ui_modules=my_uimodules"
当tornado在处理模板时,如果碰到如下的语句, 它就会去刚才设置的ui_modules模块中去找 xxxx模板驱动
{% module xxxx %}
页面代码
home.html
<!DOCTYPE html><html lang="en"><head> <meta charset="UTF-8"> <title>主页</title></head><body> {% module HeaderBar("主页") %} <h1 id="这是主页">这是主页</h1> <script src="/static/js/home.js"></script></body></html>page1.html
<!DOCTYPE html><html lang="en"><head> <meta charset="UTF-8"> <title>{{ argu1 }}</title></head><body> {% module HeaderBar("页面1") %} <h1 id="这是Page">这是Page1</h1> <ul> {% for i in argu2 %} <li>{{ i }}</li> {% end %} </ul></body></html>page2.html
<!DOCTYPE html><html lang="en"><head> <meta charset="UTF-8"> <title>Page2</title></head><body> {% module HeaderBar("页面2") %} <h1 id="这是Page">这是Page2</h1></body></html>
所有页面模板的body的第一行都添加了一个 {% module HeaderBar("页面2") %} ,如前面所讲当tornado在处理render的模板时如果碰到了这种格式的请求,就会去 ui_modules 指定的模块my_uimodules下面查找HeaderBar,并把"页面2"作为第一个参数传给了它, HeaderBar把这个参数当做location传给了 header.html.
就这样每个页面顶部导航栏的相同和不同之处都体现了出来.
