《How I stopped worrying about IO blocking Tornado》 http://www.peterbe.com/plog/worrying-about-io-blocking 1 部分代码:
class MyHandler(tornado.web.RequestHandler):
@[asynchronous](/member/asynchronous)
@[gen](/member/gen) .engine
def get(self):
http_client = AsyncHTTPClient()
response = yield gen.Task(http_client.fetch, "http://example.com")
stuff = do_something_with_response(response)
self.render("template.html", **stuff)
在nginx 配置里给管理员专配通道
upstream aroundtheworld_backends {
server 127.0.0.1:10001;
server 127.0.0.1:10002;
server 127.0.0.1:10003;
}
upstream aroundtheworld_admin_backends {
server 127.0.0.1:10004;
}
server {
server_name aroundtheworldgame.com;
root /var/lib/tornado/aroundtheworld;
...
try_files /maintenance.html @[proxy](/member/proxy) ;
location /admin {
proxy_pass http://aroundtheworld_admin_backends;
}
location @[proxy](/member/proxy) {
proxy_pass http://aroundtheworld_backends;
