1 Template
1.1 通过字符串返回
import tornado
class IndexHandler(web.RequestHandler):
def get(self):
arg = 'Template'
self.finish(f'<h1>Hello {arg}!!</h1>')
1.2 通过模板Template返回
tornado.template
一个简单的模板系统,将模板编译为Python代码。
基本用法如下
class IndexHandler1(web.RequestHandler):
def get(self):
arg = 'Template1'
t = template.Template(f'<h1>Hello {arg}!!</h1>')
self.finish(t.generate())
class IndexHandler2(web.RequestHandler):
def get(self):
arg1 = 'Template2'
t = template.Template('<h1>Hello {{arg}}!!</h1>')
self.finish(t.generate(arg = arg1))
class IndexHandler3(web.RequestHandler):
def get(self):
arg1 = 'Template3_file'
loader = template.Loader('./templates/')
self.finish(loader.load('index.html').generate(arg = arg1))
<!-- templates/index.html -->
<h1>Hello {{arg}}!!</h1>
1.3 通过模板render返回
class IndexHandler4(web.RequestHandler):
def get(self):
arg1 = 'render_Template3_file'
self.render('index.html',arg=arg1)
