Configuring the Tornado service in Python

Import Tornado.httpserver
Import Tornado.options
Import Tornado.web
From tornado.options import define, Options

From Data_util import utilsltptranslate

Define ("Port", default=8005, help= "run on the given port", Type=int)

Services started

Class Handlerltptranslate (Tornado.web.RequestHandler):
Def post (self):
Self.set_header (' Access-control-allow-origin ', ' * ')
Self.set_header (' access-control-allow-methods ', ' POST, GET, OPTIONS ')
Self.api_response ()

def api_response(self):    post_data = {}    response = {}    data=[]    try:        for key in self.request.arguments:            post_data[key] = self.get_arguments(key)[0]            text = post_data["text"]        if post_data["flag"] == "companyName":            data.append(self.application.UtilsLTPTranslate.getEnCompanyName(text))        elif post_data["flag"] == "address":            data.append(self.application.UtilsLTPTranslate.getEnAddress_2(text))        elif post_data["flag"] != "common" :            data.append(self.application.UtilsLTPTranslate.zh2en(text))        else:            data.append(self.application.UtilsLTPTranslate.zh2en(text))        response["data"] = dataexcept:        response["data"] = dataself.finish(json.dumps(response, ensure_ascii=False))

To prevent the data model from being repeatedly loaded, you need to initialize

Class Application (Tornado.web.Application):
def Init(self):
Self. Utilsltptranslate = Utilsltptranslate ()
Handlers = [(R "/ltptranslate", Handlerltptranslate)]
Tornado.web.Application. Init (Self,handlers,)

Def forservice ():
Print ("Start ... ...................)
Tornado.options.parse_command_line ()
Http_server = Tornado.httpserver.HTTPServer (Application ())
Http_server.bind (Options.port)
Http_server.start (0)
Tornado.ioloop.IOLoop.instance (). Start ()

If name = = 'main':
Forservice () #启动服务
