3种启动tornado的方式
r"""A non-blocking, single-threaded HTTP server. 翻译: 一个非阻塞的单线程HTTP服务器 A server is defined by a subclass of `.HTTPServerConnectionDelegate`, or, for backwards compatibility, a callback that takes an `.HTTPServerRequest` as an argument. The delegate is usually a `tornado.web.Application`. 翻译:服务器由".HTTPServerConnectionDelegate"的子类定义,或者,对于向后兼容,一个回调".HTTPServerRequest"作为一个参数。委托通常是 "tornado.web.Application"。 `HTTPServer` supports keep-alive connections by default (automatically for HTTP/1.1, or for HTTP/1.0 when the client requests ``Connection: keep-alive``). 翻译:默认情况下,HTTPServer支持keep-alive连接(自动为HTTP/1.1,或HTTP/1.0,当客户端请求的连接:维生”)。 If ``xheaders`` is ``True``, we support the ``X-Real-Ip``/``X-Forwarded-For`` and ``X-Scheme``/``X-Forwarded-Proto`` headers, which override the remote IP and URI scheme/protocol for all requests. These headers are useful when running Tornado behind a reverse proxy or load balancer. The ``protocol`` argument can also be set to ``https`` if Tornado is run behind an SSL-decoding proxy that does not set one of the supported ``xheaders``. 翻译: 如果"xheader"是"True",我们支持``X-Real-Ip``/``X-Forwarded-For````X-Scheme``/``X-Forwarded-Proto``的头,它覆盖了 所有请求的远程IP和URI模式/协议。这些头当在反向代理或负载下运行Tornado时是有用的均衡器。"protocol协议"的参数也可以设置为"https"。 如果Tornado是在一个SSL-decoding的代理后面运行的,它不会设置一个支持的“xheaders””。 By default, when parsing the ``X-Forwarded-For`` header, Tornado will select the last (i.e., the closest) address on the list of hosts as the remote host IP address. To select the next server in the chain, a list of trusted downstream hosts may be passed as the ``trusted_downstream`` argument. These hosts will be skipped when parsing the ``X-Forwarded-For`` header. 翻译: 默认情况下,当解析``X-Forwarded-For``的header时,Tornado将会 选择最后一个(例如最接近的)在主机列表上的地址 远程主机IP地址。要选择链中的下一个服务器,一个列表 受信任的下游主机可以作为``trusted_downstream``“托管” 论点。在解析``X-Forwarded-For``时,这些主机将被跳过头。 To make this server serve SSL traffic, send the ``ssl_options`` keyword argument with an `ssl.SSLContext` object. For compatibility with older versions of Python ``ssl_options`` may also be a dictionary of keyword arguments for the `ssl.wrap_socket` method.:: 翻译: 要使这个服务器服务于SSL流量,请发送“ssloptions”关键字 用“ssl”进行论证。SSLContext”对象。为了与旧版本的兼容性 Python“ssloptions”的版本也可能是关键字的字典 关于“ssl”的争论。wrap_socket”方法。 针对https的做法 ssl_ctx = ssl.create_default_context(ssl.Purpose.CLIENT_AUTH) ssl_ctx.load_cert_chain(os.path.join(data_dir, "mydomain.crt"), os.path.join(data_dir, "mydomain.key")) HTTPServer(applicaton, ssl_options=ssl_ctx) from tornado.httpserver import HTTPServer from tornado.ioloop import IOLoop `HTTPServer` initialization follows one of three patterns (the initialization methods are defined on `tornado.tcpserver.TCPServer`): 1. `~tornado.tcpserver.TCPServer.listen`: simple single-process:: 单进程 server = HTTPServer(app) server.listen(8888) IOLoop.current().start() In many cases, `tornado.web.Application.listen` can be used to avoid the need to explicitly create the `HTTPServer`. 2. `~tornado.tcpserver.TCPServer.bind`/`~tornado.tcpserver.TCPServer.start`: simple multi-process:: server = HTTPServer(app) server.bind(8888) server.start(0) # Forks multiple sub-processes // Forks 多个单进程 IOLoop.current().start() When using this interface, an `.IOLoop` must *not* be passed to the `HTTPServer` constructor. `~.TCPServer.start` will always start the server on the default singleton `.IOLoop`. 3. `~tornado.tcpserver.TCPServer.add_sockets`: advanced multi-process:: # 高级的多进程, 这个好处就是同脚本启动多个不同端口服务, 2则不可以 sockets = tornado.netutil.bind_sockets(8888) tornado.process.fork_processes(0) # 10 server = HTTPServer(app) server.add_sockets(sockets) IOLoop.current().start() The `~.TCPServer.add_sockets` interface is more complicated, but it can be used with `tornado.process.fork_processes` to give you more flexibility in when the fork happens. `~.TCPServer.add_sockets` can also be used in single-process servers if you want to create your listening sockets in some way other than `tornado.netutil.bind_sockets`. .. versionchanged:: 4.0 Added ``decompress_request``, ``chunk_size``, ``max_header_size``, ``idle_connection_timeout``, ``body_timeout``, ``max_body_size`` arguments. Added support for `.HTTPServerConnectionDelegate` instances as ``request_callback``. .. versionchanged:: 4.1 `.HTTPServerConnectionDelegate.start_request` is now called with two arguments ``(server_conn, request_conn)`` (in accordance with the documentation) instead of one ``(request_conn)``. .. versionchanged:: 4.2 `HTTPServer` is now a subclass of `tornado.util.Configurable`. .. versionchanged:: 4.5 Added the ``trusted_downstream`` argument.

tornado https 该怎么写
翻译: 要使这个服务器服务于SSL流量,请发送“ssloptions”关键字 用“ssl”进行论证。SSLContext”对象。为了与旧版本的兼容性 Python“ssloptions”的版本也可能是关键字的字典 关于“ssl”的争论。wrap_socket”方法。 针对https的做法 ssl_ctx = ssl.create_default_context(ssl.Purpose.CLIENT_AUTH) ssl_ctx.load_cert_chain(os.path.join(data_dir, "mydomain.crt"), os.path.join(data_dir, "mydomain.key")) HTTPServer(applicaton, ssl_options=ssl_ctx)
方法二、
server = HTTPServer(application, max_buffer_size=504857600, ssl_options={"certfile":"/etc/letsencrypt/live/
zkey.cc/fullchain.pem", "keyfile":"/etc/letsencrypt/live/
zkey.cc/privkey.pem"})
第一种启动方式
from tornado.httpserver import HTTPServer from tornado.ioloop import IOLoop `HTTPServer` initialization follows one of three patterns (the initialization methods are defined on `tornado.tcpserver.TCPServer`): 1. `~tornado.tcpserver.TCPServer.listen`: simple single-process:: 单进程 server = HTTPServer(app) server.listen(8888) IOLoop.current().start() In many cases, `tornado.web.Application.listen` can be used to avoid the need to explicitly create the `HTTPServer`.
第二种启动方式
