首先安装tornado：我用的最新版5.1.1
cmd 输入命令 pip install tornado
建立hello world页面及tornado简单页面，并配置template和static文件路径，url分发：
这里要注意：py文件名不能用tornado，import时会报错！
import tornado.ioloop
import tornado.web
class MainHandler(tornado.web.RequestHandler):
def get(self):
self.write("Hello, world")
#自己扩展url指向的类，调用其对应方法post/get
class IndexHandler(tornado.web.RequestHandler):
def get(self):
self.render("index.html")
def post(self, *args, **kwargs):
self.write("post request")
#配置文件
settings={
"template_path":"template",
"static_path":"static",
#static文件设置别名
"static_url_prefix":"/ray/",
}
#尾部**settings为加载配置文件
def make_app():
return tornado.web.Application([
(r"/", MainHandler),
(r"/index.html", IndexHandler),
],**settings)
if __name__ == "__main__":
app = make_app()
app.listen(8888)
tornado.ioloop.IOLoop.current().start()index.html:
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>index</title>
</head>
<body>
<h1>这是个一个主页</h1>
<form action="/index.html" method="post">
<p> username:<input type = "text"></p>
<p> password:<input type = "password"></p>
<p> <input type = "submit" value="提交"></p>
</form>
<img src="/ray/123.jpg" />
<!--<img src="/static/123.jpg" />-->
</body>
</html>浏览器效果:
